Rental Habitability Laws by State: Mold, Pests, Heat and Air Conditioning (2026)
What a landlord must do about mold, pests and bed bugs, heat and air conditioning — state by state, with the statute or code behind each rule.
The habitability baseline
Almost every state requires rental housing to be fit to live in. Specific rules on mold, pests, heat or cooling are less common: where a state has no specific statute, these problems are usually handled under the general duty to keep the unit habitable and make repairs after notice. Local housing codes often set temperatures and pest rules too, so check your city.
Mold, Pests, Heat & AC: all 50 states and DC
| State | Mold | Pests & bed bugs | Heat | Air conditioning |
|---|---|---|---|---|
| Alabama | No statute — general habitability/repair duty applies. Alabama has no mold disclosure or mold remediation law for rentals. The landlord must comply with building and housing codes affecting health and safety and must make all repairs needed to keep the premises habitable. Ala. Code § 35-9A-204(a)(1)-(2) | No statute specifically on pests or bed bugs. Pest problems fall under the landlord's general duty to keep the premises habitable and common areas clean and safe. The tenant must keep the unit as clean and safe as conditions permit and dispose of garbage in a clean and safe manner. Ala. Code §§ 35-9A-204(a)(2)-(3), 35-9A-301(2)-(3) | Yes. The landlord must supply reasonable heat, unless the building is not required by law to have heating or the heat is generated by equipment in the tenant's exclusive control and supplied by a direct utility connection. The landlord must also keep any heating system it supplies in good and safe working order. State law sets no minimum indoor temperature or heating season. Ala. Code § 35-9A-204(a)(4), (6) | No state requirement to provide air conditioning and no maximum indoor temperature. If the landlord supplies air conditioning, the landlord must keep it in good and safe working order. Ala. Code § 35-9A-204(a)(4) |
| Alaska | No statute — general habitability/repair duty applies. Alaska has no mold disclosure or remediation law for rentals. The landlord must make all repairs and do whatever is necessary to keep the premises fit and habitable, and keep ventilating systems it supplies in good working order. AS 34.03.100(a)(1), (3) | No statute specifically on pests or bed bugs. Infestations fall under the landlord's general duty to keep the premises fit and habitable and common areas clean and safe. The tenant must keep the unit clean and safe and dispose of garbage in a clean and safe manner. AS 34.03.100(a)(1)-(2); AS 34.03.120(a)(1)-(2) | Yes. The landlord must supply reasonable amounts of heat at all times, insofar as energy conditions permit, unless the heat is generated by an installation in the tenant's exclusive control with a direct utility connection. If the landlord deliberately or negligently fails to supply heat, the tenant may give written notice and then buy reasonable heat and deduct the cost from rent, recover damages, or obtain substitute housing. State law sets no minimum indoor temperature. AS 34.03.100(a)(3), (5); AS 34.03.180 | No state requirement to provide air conditioning and no maximum indoor temperature. If the landlord supplies air conditioning, it must be kept in good and safe working order. AS 34.03.100(a)(3) |
| Arizona | No statute — general habitability/repair duty applies. Arizona has no mold disclosure or remediation law for rentals. The landlord must comply with building codes materially affecting health and safety and make all repairs needed to keep the premises fit and habitable. A.R.S. § 33-1324(A)(1)-(2) | Arizona has a bed-bug statute. Landlords must give bed-bug educational materials to existing and new tenants and may not rent a unit they know has a current bed-bug infestation. Tenants may not knowingly move infested items into the unit and must notify the landlord in writing or electronically if they know bed bugs are present. Other pests fall under the general duty to keep the premises fit and habitable. A.R.S. § 33-1319; § 33-1324(A)(2) | Yes. The landlord must supply reasonable heat when required by seasonal weather, unless the building is not required by law to have heating or the heat comes from equipment in the tenant's exclusive control with a direct utility connection. If the landlord deliberately or negligently fails to supply heat, the tenant may give notice and buy heat and deduct the cost, recover damages, or get substitute housing. State law sets no minimum temperature. A.R.S. §§ 33-1324(A)(6), 33-1364 | Yes, where air conditioning or cooling units are installed and offered. The landlord must supply reasonable air conditioning or cooling when required by seasonal weather and keep those systems in good working order. Failure to supply it is treated like a failure to supply heat or water, with the same tenant remedies. State law sets no maximum indoor temperature and does not require a landlord to install AC. A.R.S. §§ 33-1324(A)(4), (6), 33-1364(A) |
| Arkansas | No statute — Arkansas has no mold disclosure or remediation law for rentals. Arkansas's implied residential quality standards (for leases entered into or renewed after November 1, 2021) require only running hot and cold water, electricity, potable water, code-compliant sewer and plumbing, a functioning roof and building envelope, and working heat and air conditioning if it served the unit when the lease was signed. Mold is not listed. Ark. Code Ann. § 18-17-502 (added by Act 1052 of 2021) | No statute on pests or bed bugs. They are not among Arkansas's implied quality standards, so the lease and local codes govern who treats them. The tenant must keep the unit reasonably clean and safe and dispose of garbage in a reasonably clean and safe manner. Ark. Code Ann. §§ 18-17-502, 18-17-601(2)-(3) | A functioning heating system is required only to the extent heating served the premises when the lease was signed (leases entered into or renewed after November 1, 2021). State law sets no minimum temperature. If heat fails, the tenant must give written notice; if the landlord does not fix it within 30 days and rent is current, the tenant may end the lease without penalty and get the deposit back. The tenant may not withhold rent. Ark. Code Ann. § 18-17-502(a)(6), (d) | A functioning air-conditioning system is required only if air conditioning served the premises when the lease was signed (leases entered into or renewed after November 1, 2021). There is no requirement to install AC and no maximum indoor temperature. The remedy is the same 30-day notice and lease termination as for heat. Ark. Code Ann. § 18-17-502(a)(6), (d) |
| California | Visible mold growth, as determined by a health officer or code enforcement officer, and dampness of habitable rooms are listed as substandard housing conditions, which make a unit untenantable under the landlord's repair duty. Minor mold on surfaces that can collect moisture during normal use is excluded. The Toxic Mold Protection Act also requires landlords to give written mold disclosures and a state mold booklet to tenants, but those duties do not start until the Department of Public Health adopts mold exposure standards, guidelines and the booklet. Cal. Health & Safety Code § 17920.3(a)(11), (a)(13); Cal. Civ. Code § 1941.1(a); Health & Safety Code §§ 26147, 26148 | The landlord must keep the building, grounds and all areas it controls clean and free of rodents and vermin, and insect, vermin or rodent infestation is a substandard condition. Under the bed-bug law, the landlord may not show or rent a vacant unit it knows has a current bed-bug infestation, must give every new tenant a written bed-bug information notice (all existing tenants since January 1, 2018), and must notify tenants in writing within two business days of a pest control operator's findings for inspected units (and all tenants for confirmed common-area infestations). Tenants must cooperate with inspections. Cal. Civ. Code §§ 1941.1(a)(6), 1954.602, 1954.603, 1954.604, 1954.605; Health & Safety Code § 17920.3(a)(12) | Yes. A unit is untenantable if it substantially lacks heating facilities that met code when installed and are kept in good working order, and lack of adequate heating is a substandard condition. State housing regulations (Title 25) require dwelling units to be able to maintain a minimum indoor temperature. Cal. Civ. Code § 1941.1(a)(4); Health & Safety Code § 17920.3(a)(6); Cal. Code Regs., tit. 25, § 34 | No state requirement to provide air conditioning and no state maximum indoor temperature for rentals. The state housing department has recommended that the Legislature consider a maximum safe indoor air temperature of 82°F for dwellings, but that recommendation is not law. Cal. Civ. Code § 1941.1; HCD, Policy Recommendations: Recommended Maximum Safe Indoor Air Temperature (2025 Report to the Legislature, under AB 209 of 2022) |
| Colorado | Yes. A rental is legally uninhabitable if there is mold associated with dampness, or any other damp condition, that would materially interfere with the tenant's health or safety if not fixed. Minor mold on surfaces that collect moisture through normal use is excluded. The landlord must make sure the unit is habitable before leasing it and must fix such conditions under the warranty of habitability; the tenant may use the remedies in § 38-12-507. C.R.S. §§ 38-12-503, 38-12-505(1)(a), (3) | The landlord must provide appropriate extermination for rodent, vermin, pest or insect infestations throughout the premises. Under the bed-bug law, the tenant must promptly notify the landlord in writing or electronically; within 96 hours the landlord must get the unit inspected by a qualified inspector, and inspect contiguous units if bed bugs are found. The landlord must give written results within two business days and start treatment within five business days. The landlord pays for inspection and treatment, and may not rent a unit it knows or suspects has bed bugs; on request it must disclose bed bugs in the past eight months and the last clean inspection date. C.R.S. § 38-12-505(1)(b)(VII)-(VIII); §§ 38-12-1001 to 38-12-1007 | Yes. A unit that substantially lacks functioning heating facilities that met code when installed and are kept in good working order is uninhabitable. Lack of functioning heating from October through April is presumed to materially interfere with the tenant's life, health or safety. State law sets no minimum indoor temperature. C.R.S. § 38-12-505(1)(b)(V), (4)(d) | No state requirement to provide air conditioning or maximum indoor temperature. However, a landlord may not prohibit or restrict a tenant from installing or using a portable cooling device (such as a window or portable AC unit) unless it would violate codes or law, violate the manufacturer's safety guidelines, damage the premises, or exceed the electrical capacity. A landlord that restricts them must disclose the restrictions in writing and give information on cooled common spaces or nearby community cooling spaces. Violating these cooling rules makes the unit uninhabitable. C.R.S. § 38-12-505(1)(b)(XVI), (7) |
| Connecticut | No statute — general habitability/repair duty applies. Connecticut has no mold-specific disclosure or remediation law for rentals. The landlord must comply with the tenement-house law and all building and housing codes materially affecting health and safety, and make all repairs needed to keep the premises fit and habitable. Stricter local codes take precedence. Conn. Gen. Stat. § 47a-7(a)(1)-(2), (b) | Connecticut has a detailed bed-bug statute. The tenant must promptly tell the landlord orally or in writing about a known or suspected infestation. Within five business days the landlord must inspect (or have a qualified inspector inspect) the unit and contiguous units it owns, and if bed bugs are found, begin effective treatment within five business days. The landlord pays for inspection and treatment; the tenant pays to prepare the unit and must cooperate, and can be liable for extra treatments caused by knowing, unreasonable noncompliance. The landlord may not rent a unit it knows or suspects is infested, must disclose current infestations in the unit or contiguous units before renting, and on request must give the date of the last clean inspection. Conn. Gen. Stat. § 47a-7a | Yes. The landlord must supply reasonable heat, unless the building is not required by law to have heating or the heat is generated by equipment in the tenant's exclusive control or supplied by a direct utility connection, and must keep heating facilities in good and safe working order. If the landlord fails to supply heat for reasons within its control, the tenant may give notice and buy heat and deduct the cost from rent, or get substitute housing if not restored within 48 hours. Conn. Gen. Stat. §§ 47a-7(a)(4), (6), 47a-13 | No state requirement to provide air conditioning and no maximum indoor temperature. The landlord must keep any facilities and appliances it supplies in good and safe working order, and the tenant must use air conditioning and other facilities reasonably. Conn. Gen. Stat. §§ 47a-7(a)(4), 47a-11(e) |
| Delaware | No statute — general habitability/repair duty applies. Delaware has no mold disclosure or remediation law for rentals. The landlord must comply with all state and local housing codes, provide a unit that does not endanger the health, welfare or safety of tenants, and make all repairs needed to keep the unit in the condition it was, or should have been, at the start of the tenancy. 25 Del. C. § 5305(a)(1)-(2), (4) | Delaware has a bed-bug statute. Before renting, the landlord must visually inspect the unit for evidence of bed bugs and disclose if adjacent units are infested or being treated. After a report of a known or suspected infestation, the landlord must inspect or get a pest management professional to inspect within 120 hours, start professional remediation within 14 days of notice if bed bugs are found, inspect adjacent units within 5 days, notify affected tenants of the findings, and keep written records. The landlord pays for investigation and remediation if the tenant reports within 60 days of move-in or within 30 days of an infestation being found in an adjoining unit; for later reports the tenant shares reasonable remediation costs for the tenant's unit (except in public housing authority properties). Tenants may not knowingly bring in infested belongings. 25 Del. C. § 5317 | Only if the rental agreement says so: the landlord must supply (or arrange) water, hot water, heat and electricity when the lease so specifies. If the landlord substantially fails to provide heat, the tenant may, on written notice, procure substitute housing with rent abating, or keep two-thirds of the per-diem rent while heat is not supplied, among other remedies. State law sets no minimum indoor temperature. 25 Del. C. §§ 5305(b)(2), 5308 | No state requirement to provide air conditioning and no maximum indoor temperature. The landlord must keep any electrical, plumbing and other facilities it supplies in good working order. 25 Del. C. § 5305(a)(5) |
| District of Columbia | Yes. After written or electronic notice from a tenant that mold or suspected mold exists in the unit or a common area, the property owner must inspect within 7 days and remediate within 30 days of the inspection (unless a shorter deadline is ordered). Mold above the District's contamination threshold must be remediated by a licensed mold remediation professional. A professional mold assessment finding contamination creates a rebuttable presumption of a housing code violation, and a court may award assessment costs, attorney fees and, for bad-faith failure to remediate within 60 days, treble damages. When a tenant applies, the landlord must disclose either a 3-year history of mold contamination in the unit and common areas or proof of proper remediation. D.C. Code §§ 8-241.01, 8-241.02, 8-241.04, 8-241.05(a); D.C. Tenant Bill of Rights (OTA, rev. Sept. 25, 2026) | No bed-bug-specific statute. Under the D.C. Housing Code, all rental dwellings must be free of insects and rodents, and structures and exterior property must be kept free from rodent harborage and infestation. Keeping the premises free of rodents and pests is part of the implied warranty of habitability; maintenance of the unit is a shared responsibility, while common areas are primarily the landlord's responsibility. D.C. Housing Code (14 DCMR) and Property Maintenance Code (12G DCMR), as summarized by the Department of Buildings; D.C. Tenant Bill of Rights § 7 | Yes. Heating equipment must keep all habitable rooms, bathrooms and toilet rooms at no less than 68°F from 6:30 a.m. to 11:00 p.m. and 65°F from 11:00 p.m. to 6:30 a.m., from October 1 to May 1. With a two-pipe system or any system needing more than 15 days to switch from air conditioning to heat, heat must start no later than October 15. Landlords must also have heating and hot water systems professionally tested annually. 14 DCMR § 501; D.C. Tenant Bill of Rights § 7 | Where an air-conditioning system is provided, it must be operated and maintained from no later than May 15 through no earlier than September 15, keeping the rooms it serves at the greater of 78°F or at least 15°F below the outside temperature. The Housing Code does not require a landlord to install air conditioning where none is provided. D.C. Property Maintenance Code (12G DCMR) / Housing Code (14 DCMR), as summarized by the Department of Buildings |
| Florida | No statute — Florida has no mold-specific landlord-tenant statute. Mold is handled under the landlord's general duty to comply with applicable building, housing, and health codes (or, where none apply, to keep structural components and plumbing in good repair). Fla. Stat. § 83.51(1) | For units other than a single-family home or duplex, unless otherwise agreed in writing, the landlord must make reasonable provisions for extermination of rats, mice, roaches, ants, wood-destroying organisms, and bedbugs. If the tenant must temporarily vacate for extermination, the landlord must give 7 days' written notice (in person, by mail, or by e-mail under s. 83.505), must abate rent, and the tenant cannot be required to vacate more than 4 days; the landlord is not liable for other damages. For single-family homes and duplexes, pest duties depend on the lease and local codes. Fla. Stat. § 83.51(2)(a)1. | Yes, for units other than single-family homes and duplexes (unless otherwise agreed in writing): the landlord must make reasonable provisions for functioning facilities for heat during winter, plus running water and hot water. No minimum temperature or heating season is set by state statute. Fla. Stat. § 83.51(2)(a)5. | No statute — Florida law does not require landlords to provide air conditioning or set a maximum indoor temperature. If the lease or unit includes A/C, local codes and the lease govern repair. Fla. Stat. § 83.51 |
| Georgia | No statute — Georgia has no mold-specific landlord-tenant law (no mold disclosure or remediation standard). Mold is addressed under the landlord's general duty to keep the premises in repair and, since July 1, 2024, the implied term in every residential lease that the premises are fit for human habitation. O.C.G.A. § 44-7-13(a), (b) (as amended by HB 404, 2024) | No statute — Georgia law does not specifically assign pest or bed-bug treatment or require a bed-bug disclosure. Pest problems fall under the landlord's general repair duty and the fit-for-habitation requirement; the state handbook advises that leases spell out pest control, including how often it occurs. O.C.G.A. § 44-7-13; Georgia Landlord-Tenant Handbook (DCA, rev. 8-29-24), p. 10 | No statewide statute sets a heat requirement, minimum temperature, or heating season. Under the general repair duty, the state handbook says landlords must keep electric, heating, cooling, and plumbing in working order. O.C.G.A. § 44-7-13; Georgia Landlord-Tenant Handbook (DCA, rev. 8-29-24), p. 11 | No statute requires landlords to provide air conditioning or sets a maximum indoor temperature. Where cooling equipment is provided, the state handbook says the landlord must keep it in working order as part of the repair duty. O.C.G.A. § 44-7-13; Georgia Landlord-Tenant Handbook (DCA, rev. 8-29-24), p. 11 |
| Hawaii | No statute — Hawaii's Residential Landlord-Tenant Code has no mold-specific disclosure or remediation rule. Mold is addressed under the landlord's general duties to comply with building and housing laws materially affecting health and safety and to make all repairs needed to keep the premises habitable. HRS § 521-42(a)(1), (3) | No statute — Hawaii law does not specifically assign pest or bed-bug treatment and has no bed-bug disclosure rule. Infestations are handled under the landlord's habitability and code-compliance duties and the tenant's duty to keep the unit clean and dispose of garbage properly. HRS §§ 521-42(a)(1), (3), (5); 521-51(2), (3) | No statute — Hawaii law does not require landlords to provide heat or set minimum indoor temperatures. Heating equipment the landlord supplies must be kept in good working order as one of the 'facilities and appliances supplied by the landlord.' HRS § 521-42(a)(4) | No statute — landlords are not required to provide air conditioning, and there is no maximum indoor temperature. If the landlord supplies A/C or fans, they must be maintained in good working order, subject to reasonable wear and tear. HRS § 521-42(a)(4) |
| Idaho | No statute — Idaho has no mold-specific landlord-tenant law and no state agency that regulates mold inspection or removal in rentals. Mold is handled under the tenant's right to sue a landlord who maintains the premises in a manner hazardous to health or safety, fails to provide reasonable waterproofing and weather protection, or fails to maintain plumbing and ventilation facilities. The Attorney General advises tenants to report leaks, excess moisture, or recurring mold to the landlord immediately. Idaho Code § 6-320(a)(1)–(3); Idaho AG, Landlord and Tenant Manual (July 2026), pp. 16–17 | No statute — Idaho law does not specifically assign pest or bed-bug treatment or require a bed-bug disclosure. The Attorney General lists insect infestations as an example of a condition that may violate housing standards and the landlord's duty not to maintain the premises in a manner hazardous to health or safety. Idaho Code § 6-320(a)(3); Idaho AG, Landlord and Tenant Manual (July 2026), pp. 11–12 | No statute sets a minimum temperature or requires landlords to supply heat, but a tenant may sue a landlord who fails to maintain in good working order heating facilities the landlord supplied. The Attorney General lists nonfunctioning heating units as a condition that may violate housing standards. Idaho Code § 6-320(a)(2); Idaho AG, Landlord and Tenant Manual (July 2026), p. 12 | No statute requires landlords to provide air conditioning or sets a maximum indoor temperature. If the landlord supplies cooling facilities, the landlord must keep them in good working order, and a tenant may sue for damages and specific performance if it does not. Idaho Code § 6-320(a)(2) |
| Illinois | No statute — Illinois has no statewide mold disclosure or remediation law for rentals. Mold falls under the landlord's general duty to keep the unit fit to live in, make necessary repairs, and comply with state and local health and housing codes. For small repairs required by the lease or by law (lesser of $500 or half a month's rent), a tenant may use the statutory repair-and-deduct procedure after 14 days' written notice. Illinois Attorney General, Landlord and Tenant Rights and Laws, p. 1; 765 ILCS 742/5 | No statute — Illinois has no statewide pest or bed-bug law for private rentals. Infestations are handled under the landlord's duty to keep the unit fit to live in and comply with local health and housing codes. Illinois Attorney General, Landlord and Tenant Rights and Laws, p. 1 | No statewide statute sets a heat requirement, minimum temperature, or heating season for private rentals. Heat is generally covered by the landlord's duty to keep the unit fit to live in and by local housing codes, which often set minimum temperatures (for example, in Chicago). Illinois Attorney General, Landlord and Tenant Rights and Laws, p. 1 | No statute — Illinois does not require landlords to provide air conditioning or set a maximum indoor temperature for private rentals. Illinois Attorney General, Landlord and Tenant Rights and Laws, p. 1 |
| Indiana | No statute — Indiana has no mold-specific landlord-tenant law. Mold is handled under the landlord's duties to deliver the premises in a safe, clean, and habitable condition and to comply with applicable health and housing codes. A tenant may sue to enforce these duties after giving notice and a reasonable time to repair. IC 32-31-8-5(1), (2); IC 32-31-8-6 | No statute — Indiana does not specifically assign pest or bed-bug treatment and has no bed-bug disclosure rule. Infestations fall under the landlord's safe, clean, and habitable delivery duty and health-code compliance, and the tenant's duties to keep the unit reasonably clean and comply with tenant obligations under health and housing codes. IC 32-31-8-5(1), (2); IC 32-31-7-5(1), (2) | Yes, if a heating system is provided at the time the lease is signed: the landlord must maintain it in good and safe working condition, and it must be sufficient to adequately supply heat at all times. No specific minimum temperature or heating season is set by state statute. Plumbing must supply a reasonable amount of hot and cold running water at all times. IC 32-31-8-5(4)(B), (D) | No duty to install air conditioning, but if heating, ventilating, and air conditioning systems are provided when the lease is entered into, the landlord must provide and maintain them in good and safe working condition. No maximum indoor temperature is set. IC 32-31-8-5(4)(D) |
| Iowa | No statute — Iowa has no mold-specific landlord-tenant law. Mold is handled under the landlord's duties to comply with building and housing codes materially affecting health and safety and to make all repairs and do whatever is necessary to keep the premises fit and habitable. Iowa Code § 562A.15(1)(a)(1), (2) | No statute — Iowa does not specifically assign pest or bed-bug treatment or require a bed-bug disclosure. Infestations fall under the landlord's fit-and-habitable and code-compliance duties; tenants must keep their unit clean and dispose of garbage and waste in a clean and safe manner. Iowa Code §§ 562A.15(1)(a)(1), (2), (5); 562A.17(2), (3) | Yes. The landlord must supply running water, reasonable amounts of hot water at all times, and reasonable heat — unless the building is not required by law to be so equipped or the heat/hot water is generated by equipment under the tenant's exclusive control with a direct utility connection. Heating facilities supplied by the landlord must be kept in good and safe working order. No numeric minimum temperature is set by state statute. Iowa Code § 562A.15(1)(a)(4), (6) | No duty to install air conditioning and no maximum indoor temperature. Air-conditioning facilities supplied or required to be supplied by the landlord must be maintained in good and safe working order. Iowa Code § 562A.15(1)(a)(4) |
| Kansas | No statute — Kansas has no mold-specific landlord-tenant law. Mold is handled under the landlord's duty to comply with building and housing codes materially affecting health and safety and to maintain plumbing, sanitary, and ventilating systems in good and safe working order. K.S.A. 58-2553(a)(1), (3) | No statute — Kansas does not specifically assign pest or bed-bug treatment and has no bed-bug disclosure rule. Infestations fall under the landlord's code-compliance duty; tenants must keep their unit clean and remove garbage and waste in a clean and safe manner, and are responsible for damage they or their guests or animals cause. K.S.A. 58-2553(a)(1), (4); 58-2555(b), (c), (f) | Yes. The landlord must supply running water, reasonable amounts of hot water at all times, and reasonable heat — unless the building is not required by law to be so equipped or the heat or hot water comes from equipment under the tenant's exclusive control with a direct utility connection. Heating appliances the landlord supplies must be kept in good and safe working order. No numeric minimum temperature is set by state statute. K.S.A. 58-2553(a)(3), (5) | No duty to install air conditioning and no maximum indoor temperature.

| Kentucky | No statute — Kentucky has no mold-specific landlord-tenant law. Where the Uniform Residential Landlord and Tenant Act (URLTA) has been locally adopted, mold falls under the landlord's duties to comply with building and housing codes materially affecting health and safety and to do whatever is necessary to keep the premises fit and habitable. Outside URLTA areas, no statewide habitability statute applies; the lease and local codes govern. KRS 383.595(1)(a), (b); KRS 383.500 | No statute — Kentucky does not specifically assign pest or bed-bug treatment and has no bed-bug disclosure rule. In URLTA areas, infestations fall under the landlord's code-compliance and fit-and-habitable duties and the tenant's duty to keep the unit clean and dispose of garbage properly. Elsewhere, the lease and local codes govern. KRS 383.595(1)(a), (b); KRS 383.605(2), (3) | In URLTA areas, yes: the landlord must supply running water, reasonable amounts of hot water at all times, and reasonable heat between October 1 and May 1 — unless the building is not required by law to be so equipped or heat/hot water is produced by equipment under the tenant's exclusive control with a direct utility connection. Heating facilities the landlord supplies must be kept in good and safe working order. No numeric minimum temperature is set. Outside URLTA areas, there is no statewide heat statute. KRS 383.595(1)(d), (e) | No duty to install air conditioning and no maximum indoor temperature. In URLTA areas, air-conditioning facilities supplied or required to be supplied by the landlord must be kept in good and safe working order. KRS 383.595(1)(d) |
| Louisiana | No statute — Louisiana has no mold disclosure or remediation law. The Civil Code's general lessor duties apply. The lessor must maintain the property in a condition suitable for its leased purpose, make all necessary repairs during the lease (except those the lessee is responsible for), and warrant that it is free of vices or defects that prevent its use, including defects that arise later and defects unknown to the lessor. If the lessor fails to repair within a reasonable time after demand, the lessee may repair and deduct reasonable costs. La. C.C. arts. 2682(2), 2691, 2696, 2697, 2694 | No statute — no state law specifically assigns pest or bed bug treatment or requires disclosure. Infestations are handled under the lessor's general duties to maintain the property in suitable condition, make necessary repairs, and warrant against vices and defects. The lessee must repair damage caused by their own fault or that of people on the premises with their consent. La. C.C. arts. 2682, 2691, 2692, 2696 | No statute — Louisiana law sets no minimum indoor temperature or heating season. If heating is part of the leased premises, the lessor's general duty to maintain the property in a condition suitable for its leased purpose and to make necessary repairs applies. La. C.C. arts. 2682, 2691 (Civil Code lease-obligation articles 2682-2698 checked) | No statute — Louisiana does not require landlords to provide air conditioning or set a maximum indoor temperature. If AC is provided as part of the lease, the general maintenance and repair duty applies. La. C.C. arts. 2682, 2691 |
| Maine | Yes, by statute. It is a breach of the implied warranty of habitability for a landlord to offer for rent a unit with a leaking event (a water leak from flooding or a roof, window, door, plumbing, foundation or appliance failure), or chronic moisture or humidity outside the tenant's control, that results in the growth of mold, bacteria or other biological organisms. A tenant who gave written notice, is current on rent and did not cause the condition can sue; the court can order repairs, reduce rent to the unit's fair value, or let the tenant temporarily vacate without paying. Municipalities may adopt stricter standards. 14 M.R.S. § 6021(1), (3), (4), (6-B) (added by PL 2025, c. 515) | Detailed bed bug statute. The landlord must inspect within 5 days after written or oral notice from a tenant, contact a licensed pest control agent within 10 days after confirming an infestation, and pay for treatment by an insured agent. Before renting, the landlord must disclose if an adjacent unit is infested or being treated, and on request must give the last date the unit or adjacent units were inspected and found free of bed bugs. A landlord may not rent a unit known or suspected to be infested. Tenants must promptly report suspected bed bugs, allow access on reasonable notice, and follow treatment measures. A tenant who unreasonably fails to cooperate pays for the resulting treatments. A noncompliant landlord owes the greater of $250 or actual damages, plus attorney fees. 14 M.R.S. § 6021-A | When the lease obligates the landlord to provide heat, the heating system must be able to keep at least 68°F (measured 3 feet from exterior walls and 5 feet above the floor, at an outside temperature of -20°F). The landlord must not keep it so cold that it is injurious to health and must keep pipes and systems from freezing. Falling short breaches the warranty of habitability. A landlord and tenant can agree in a separate signed writing to a lower setting, but not below 62°F, with a fair rent reduction. The agreement is revocable and not allowed if anyone over 65 or under 5 lives there. No statewide heating season is set. 14 M.R.S. § 6021(6), (6-A) | No statute — Maine law does not require landlords to provide air conditioning or set a maximum indoor temperature. If the lease includes AC, the landlord must keep that promise. 14 M.R.S. ch. 710 (§§ 6021-6030-K checked) |
| Maryland | Yes, by statute (Maryland Tenant Mold Protection Act, effective July 1, 2025). Landlords must give each tenant the state mold information pamphlet when the lease is signed and on request, and ask the tenant to sign an acknowledgment. Within 15 days after written notice of mold from the tenant, a building occupant or the local housing-code agency, the landlord must do a mold assessment. If mold is found, the landlord must remediate it within 45 days after the assessment, or within a reasonable time if 45 days isn't feasible. Assessment and remediation must follow industry guidelines and state and local law. The landlord must keep the property properly ventilated with low indoor humidity, communicate with occupants during the work, and meet minimum livability codes. Md. Code, Real Prop. § 8-220; Md. Code, Envir. § 6-1702 (2025 Md. Laws ch. 539, SB 856) | No bed-bug-specific statute. A rodent infestation in two or more units is a listed serious defect: if the landlord fails to fix it within a reasonable time after notice (over 30 days is presumed unreasonable), the tenant may use rent escrow. Other infestations that create a health hazard can also qualify. The state Minimum Livability Code, which adopts the International Property Maintenance Code, applies where no substantially similar local code exists. Md. Code, Real Prop. § 8-211(d)(3), (d)(5), (g); COMAR 09.12.54.03-.04 | Lack of heat is a listed serious defect: if the landlord doesn't fix it within a reasonable time after notice, the tenant can use rent escrow. This does not apply when the tenant pays the utility and the lack of heat is from the tenant's own nonpayment. No state statute sets a minimum temperature. The state Minimum Livability Code adopts the 2012 International Property Maintenance Code, which contains heating standards, for housing in localities without a substantially similar local code. Md. Code, Real Prop. § 8-211(d)(1); COMAR 09.12.54.03-.04 | No statewide requirement to provide air conditioning. Under the rent-escrow statute, there is a rebuttable presumption that the absence of air conditioning is not a covered serious defect, unless it poses a serious and substantial threat to life, health or safety. Md. Code, Real Prop. § 8-211(e)(2)(iv) |
| Massachusetts | Yes, under the State Sanitary Code. Owners must keep buildings and structural elements watertight and free from excess moisture or the appearance of mold. After leaks or flooding, the owner must dry all surfaces within 48 hours of being notified or of the end of the event, whichever is sooner. No room may be used for habitation if it is subject to excess moisture. Code violations are enforced by the local board of health, and any violation not otherwise listed is deemed a condition that may endanger health or safety. Occupants must use building elements with reasonable care. No statute requires mold disclosure to tenants. 105 CMR 410.500(A)(1), (B); 410.510; 410.420(A); 410.630(A)(18); 410.020 ('Chronic Dampness') | Set by the State Sanitary Code. In buildings with 2 or more units (and rooming houses), the owner must keep the building free from infestation and is responsible for extermination, including bed bugs. In single-unit residences, the occupant is responsible unless the owner failed to maintain the structure to keep pests out. Owners must inspect each unit for pests before a new tenancy and keep documented results. Occupants must keep units sanitary and give access and follow preparation instructions for pesticide treatments. Commercial applicators must give 48 hours' written pre-notification. Failure to keep premises pest-free is a condition deemed to endanger health or safety. 105 CMR 410.550; 410.630(A)(17) | Yes. The owner must heat every habitable room and bathroom from September 15 through May 31: at least 68°F from 7:00 a.m. to 11:00 p.m. and at least 64°F from 11:01 p.m. to 6:59 a.m. Temperature is measured 5 feet above the floor, more than 5 feet from an exterior wall. A local board of health may shorten the season, ending it no earlier than May 15 or starting it no later than September 30. Failure to provide required heat is a condition deemed to endanger health or safety. 105 CMR 410.180(A), (C), (D); 410.630 | No statewide requirement to provide air conditioning. The Sanitary Code does set a ceiling: during the heating season, the heating system may not cause the temperature in any room to exceed 78°F. 105 CMR 410.180(B) |
| Michigan | No statute — Michigan has no mold disclosure or remediation law. Every residential lease includes statutory covenants that the premises and common areas are fit for their intended use, that the landlord will keep the premises in reasonable repair, and that the landlord will comply with state and local health and safety laws. The exception is disrepair caused by the tenant's willful or irresponsible conduct. Where the Housing Law of Michigan applies, the owner must keep the roof from leaking and drain rainwater so as to avoid dampness in walls and ceilings. An occupant can sue for damages and injunctive relief if unsafe or unsanitary conditions go unabated after notice. MCL 554.139(1); MCL 125.471; MCL 125.536 | No statute — no state law specifically assigns pest or bed bug treatment or requires disclosure. Infestations fall under the landlord's statutory covenants of fitness and reasonable repair and the duty to comply with health and safety laws, unless the tenant's willful or irresponsible conduct caused the problem. Local housing codes often set specific extermination duties. MCL 554.139(1) | No statewide minimum indoor temperature or heating season was found in state statute. Where the Housing Law of Michigan applies, the owner must keep heating, plumbing, ventilation and wiring in good repair. More generally, the landlord's covenants of fitness, reasonable repair and compliance with health and safety laws apply to heating the landlord supplies. Many cities set minimum temperatures in local housing codes. MCL 125.471; MCL 554.139(1) | No statute — Michigan law does not require landlords to provide air conditioning or set a maximum indoor temperature. If the landlord supplies AC, it falls under the general fitness and repair covenants. MCL 554.139; MCL 125.471 (checked) |
| Minnesota | No statute — no mold-specific disclosure or remediation law. Mold is covered by the general statutory covenants that the unit and common areas are fit for their intended use, kept in reasonable repair, and kept in compliance with state and local health and safety laws. A condition with a serious negative impact on health or safety can support an emergency tenant remedies action, and tenants can also use rent escrow or a tenant remedies action. Minn. Stat. § 504B.161, subd. 1(a)(1), (2), (4); § 504B.381, subd. 1 | The landlord's statutory duty to keep the premises in reasonable repair expressly includes extermination of insects, rodents, vermin or other pests, including bed bugs. The exception is when the problem was caused by the willful, malicious or irresponsible conduct of the tenant or someone under the tenant's control. A serious infestation is an emergency that can support an expedited emergency tenant remedies action. No bed-bug-specific disclosure statute. Minn. Stat. § 504B.161, subd. 1(a)(2); § 504B.381, subd. 1(2)(i) | Yes, statewide. The landlord must provide heat of at least 68°F in all places intended for habitation, including kitchens and bathrooms, from October 1 through April 30. The only exception is when a utility company requires and instructs the heat to be reduced. Loss of heat that the landlord is responsible for is an emergency that can support an emergency tenant remedies action. Minn. Stat. § 504B.161, subd. 1(a)(5); § 504B.381, subd. 1(2)(iv) | No statute requires landlords to provide air conditioning or sets a maximum indoor temperature. But if AC is included in the lease, a nonfunctioning air conditioner is a listed emergency that the tenant can use to seek an emergency tenant remedies order. Minn. Stat. § 504B.381, subd. 1(2)(viii) |
| Mississippi | No statute — Mississippi has no mold disclosure or remediation law. The landlord's general statutory duty applies: comply with building and housing codes that materially affect health and safety, and maintain the unit and its plumbing, heating and cooling systems in substantially the same condition as at the start of the lease, reasonable wear and tear excluded. There is no duty for defects caused by the tenant's deliberate or negligent acts. Tenants must tell the landlord about conditions that may cause damage. Miss. Code Ann. § 89-8-23; § 89-8-25(g) | No statute — no state law assigns pest or bed bug treatment or requires disclosure. Pests are governed by the general duty to comply with health and safety housing codes and maintain the premises, and by the lease. Tenants must keep their part of the premises clean and safe and dispose of garbage properly. Miss. Code Ann. § 89-8-23(1); § 89-8-25(a)-(b) | No minimum temperature or heating season is set by state law. A landlord must maintain the heating system in substantially the same condition as at the start of the lease, reasonable wear and tear excluded, unless the tenant's deliberate or negligent actions damaged it, and must comply with applicable housing codes. The lease decides whether a heating system is provided at all. Miss. Code Ann. § 89-8-23(1)(b) | No statute requires landlords to provide air conditioning or sets a maximum indoor temperature. But if the unit has a cooling system, the landlord must maintain it in substantially the same condition as at the start of the lease, reasonable wear and tear excluded, unless the tenant damaged it deliberately or negligently. Miss. Code Ann. § 89-8-23(1)(b) |
| Missouri | No statute — Missouri has no mold disclosure or remediation law. Missouri courts recognize an implied warranty of habitability as case law, not statute. Local housing codes set specific standards. If a condition that detrimentally affects habitability or sanitation violates a local housing or building code, an eligible tenant may use the statutory repair-and-deduct remedy. To qualify, the tenant must have lived there 6 consecutive months, be current on rent, and have no uncured lease-violation notices. RSMo 441.234; RSMo ch. 441 and 535 (checked) | No statute — no state law assigns pest or bed bug treatment or requires disclosure. The lease, local housing codes and the case-law implied warranty of habitability govern. Where an infestation violates a local housing code, an eligible tenant may use the repair-and-deduct remedy. RSMo ch. 441 and 535 (checked); RSMo 441.234 | No statewide minimum temperature or heating season for rentals. Heat requirements come from local housing codes and the lease. By statute, in master-metered multi-unit buildings, the utility must post notice 5 days before shutting off heat-related service for the owner's nonpayment. Tenants may then petition for a receiver, and service may not be cut while the petition is pending. RSMo 441.650; ch. 441 (checked) | No statute — Missouri law does not require landlords to provide air conditioning or set a maximum indoor temperature. RSMo ch. 441 and 535 (checked) |
| Montana | Montana Mold Disclosure Act: a landlord who knows mold is present must disclose it to the tenant before or when the lease is signed, and a landlord who knows the building was tested for mold must say so and give the tenant the test results (if available) and evidence of any later mitigation. A landlord may also give a statutory mold disclosure statement for the tenant to sign; a landlord who gives it, discloses prior testing and mitigation, and discloses known mold is shielded from liability based on the presence of or propensity for mold. No state mold-remediation standard; the general duty to keep the premises fit and habitable applies. Mont. Code Ann. §§ 70-16-701 to 70-16-703; § 70-24-303(1)(b) | No pest- or bed-bug-specific statute. The landlord must make repairs and do whatever is necessary to keep the premises fit and habitable and keep common areas clean and safe; the tenant must keep the unit reasonably clean and safe and dispose of garbage properly. Mont. Code Ann. §§ 70-24-303(1)(b)-(c), 70-24-321(1)(b)-(c) | Yes. The landlord must supply reasonable heat between October 1 and May 1 (plus running water and reasonable hot water at all times) and keep heating facilities in good and safe working order. No statewide minimum temperature is set. Exception: buildings not required by law to be equipped for heat, or units where heat is generated by an installation in the tenant's exclusive control. Mont. Code Ann. § 70-24-303(1)(d), (1)(f) | No state requirement to provide air conditioning or a maximum indoor temperature. If the landlord supplies air conditioning, it must be maintained in good and safe working order. Mont. Code Ann. § 70-24-303(1)(d) |
| Nebraska | No statute — general habitability/repair duty applies. After written or actual notice, the landlord must substantially comply with applicable minimum housing codes and do whatever is necessary to put and keep the premises fit and habitable. Neb. Rev. Stat. § 76-1419(1)(a)-(b) | No pest- or bed-bug-specific statute. The landlord must keep the premises fit and habitable and common areas clean and safe (after notice); the tenant must keep the occupied part of the premises clean and safe and dispose of garbage and waste properly. Neb. Rev. Stat. §§ 76-1419(1)(b)-(c), 76-1421(2)-(3) | Yes. The landlord must supply reasonable heat (and running water and reasonable hot water at all times) and maintain heating facilities in good and safe working order. No statewide minimum temperature or heating season is set. Exceptions: buildings not required by law to be equipped for heat, or units where heat is generated by an installation in the tenant's exclusive control supplied by a direct public utility connection. Neb. Rev. Stat. § 76-1419(1)(d), (1)(f) | No state requirement to provide air conditioning or a maximum indoor temperature. Air conditioning supplied or required to be supplied by the landlord must be kept in good and safe working order. Neb. Rev. Stat. § 76-1419(1)(d) |
| Nevada | No statute — general habitability duty applies. The landlord must maintain the unit in a habitable condition at all times; a unit is not habitable if it violates housing or health codes on health, safety, sanitation, or fitness, or substantially lacks effective waterproofing and weather protection, working plumbing, or walls, floors, and ceilings in good repair. NRS 118A.290(1) | At the start of the tenancy, the building, grounds, and other areas under the landlord's control must be clean, sanitary, and reasonably free of rodents, insects, and vermin. The tenant must keep the unit clean and safe and dispose of garbage properly. No bed-bug-specific statute. NRS 118A.290(1)(g); NRS 118A.310 | Yes. A unit is not habitable if it substantially lacks adequate heating facilities that conformed to law when installed and are maintained in good working order. No statewide minimum temperature or heating season is set. If the landlord is required to supply heat and willfully or negligently fails to, the tenant has additional remedies, including damages of up to $2,500. NRS 118A.290(1)(d); NRS 118A.380 | No state requirement to provide air conditioning or a maximum indoor temperature. Air conditioning supplied or required to be supplied by the landlord must be kept in good repair, and air conditioning is treated as an essential service when the lease or the chapter requires the landlord to supply it. NRS 118A.290(1)(i); NRS 118A.380 |
| New Hampshire | No statute — general habitability standards apply. The state minimum housing standards do not mention mold but prohibit related conditions such as roofs or walls that leak consistently and defective internal plumbing or sewage back-ups. RSA 48-A:14, II and IV | The landlord may not maintain premises infested by insects and rodents without a periodic inspection and eradication program, or infested by bed bugs without a periodic inspection and remediation program (remediation = substantially reducing bed bugs for at least 60 days). The landlord must investigate a tenant's report of insects, bed bugs, or rodents within 7 days and take reasonable measures to remediate. Tenants may not refuse access for emergency pest entry or, on 48 hours' written notice, for a bed-bug check when an adjacent, above, or below unit has bed bugs, and must follow reasonable written preparation instructions given at least 72 hours before treatment. RSA 48-A:14, I and I-a; RSA 540-A:3, IV-a, V-a to V-c | Yes. Heating facilities must be properly installed, safely maintained, in good working condition, and capable of heating all habitable rooms, bathrooms, and toilet rooms to an average of at least 65°F; when the landlord supplies heat as part of the rent, rooms must actually be kept at a minimum average of 65°F. No heating season is specified. A landlord may not willfully interrupt heat or other utility service except temporarily for repairs or emergencies. RSA 48-A:14, XI; RSA 540-A:3, I | No state requirement to provide air conditioning or a maximum indoor temperature. RSA 48-A:14 |
| New Jersey | No statute — the implied warranty of habitability and state/local housing maintenance codes apply. New Jersey has no enacted mold disclosure, testing, or remediation standard for rentals. Marini v. Ireland, 56 N.J. 130 (1970) (implied warranty of habitability); N.J.A.C. 5:10 (Regulations for Maintenance of Hotels and Multiple Dwellings) | In hotels and multiple dwellings (3+ units), the owner must eradicate insects, rats, or other pests when the infestation is in two or more units or in common areas, keep the building ratproof and free of infestation, and have qualified persons perform preventive pest procedures at least once a year (more often if infestation recurs). The state's Truth in Renting guide lists bed-bug information among the items a landlord should provide to tenants. N.J.A.C. 5:10-10.2 | Yes, for buildings of three or more units: from October 1 to May 15, every unit and habitable room must be kept at least 68°F from 6:00 a.m. to 11:00 p.m. and at least 65°F from 11:00 p.m. to 6:00 a.m. The owner must supply the fuel or energy and keep the heating system in good operating condition, regardless of lease terms, unless the tenant agrees in writing to heat a unit served by its own separately billed heating equipment. N.J.A.C. 5:10-14.3, 5:10-14.4 | No state requirement to provide air conditioning or a maximum indoor temperature. Air conditioning that was part of the original tenancy may be treated as a 'vital facility' whose failure affects habitability. Implied warranty of habitability (Marini v. Ireland, 56 N.J. 130 (1970)); N.J.A.C. 5:10 subchapter 14 (heat only) |
| New Mexico | No statute — general repair duty applies. The owner must substantially comply with applicable minimum housing codes and make repairs and do whatever is necessary to put and keep the premises in a safe condition. NMSA 1978, § 47-8-20(A)(1)-(2) | No pest- or bed-bug-specific statute. The owner must keep the premises in a safe condition and common areas safe, and provide garbage receptacles and removal; the resident must keep the occupied part of the premises clean and safe and dispose of garbage properly. NMSA 1978, §§ 47-8-20(A)(2)-(3), (5); 47-8-22(B)-(C) | Yes. The owner must supply reasonable heat (and running water and a reasonable amount of hot water at all times) and maintain heating facilities in good and safe working order. No statewide minimum temperature or heating season is set. Exceptions: buildings not required by law to be equipped for heat, or units where heat is generated by an installation in the resident's exclusive control supplied by a direct public utility connection. NMSA 1978, § 47-8-20(A)(4), (A)(6) | No state requirement to provide air conditioning or evaporative cooling, or a maximum indoor temperature. Air conditioning supplied or required to be supplied by the owner must be kept in good and safe working order. NMSA 1978, § 47-8-20(A)(4) |
| New York | No statewide mold statute — the warranty of habitability applies. Every residential lease includes a non-waivable warranty that the premises are fit for human habitation and free of conditions dangerous, hazardous, or detrimental to life, health, or safety. N.Y. Real Prop. Law § 235-b | In multiple dwellings, the owner must keep the building and its lot, yards, and passages clean and free from vermin, dirt, filth, and garbage; tenants are answerable for conditions they cause. Failure to rid an apartment of an insect infestation is an example of a breach of the warranty of habitability. No statewide bed-bug disclosure statute. N.Y. Mult. Dwell. Law § 80; N.Y. Mult. Resid. Law § 174; N.Y. Real Prop. Law § 235-b | Yes, in multiple dwellings: from October 1 through May 31, the owner must heat all living areas to at least 68°F from 6 a.m. to 10 p.m. when it is below 55°F outside, and at least 55°F from 10 p.m. to 6 a.m. when it is below 40°F outside. Local regulations may require higher temperatures. N.Y. Mult. Dwell. Law § 79; N.Y. Mult. Resid. Law § 173 | No state requirement to provide air conditioning or a maximum indoor temperature. N.Y. Mult. Dwell. Law § 79 (heat only); N.Y. Real Prop. Law § 235-b |
| North Carolina | No mold-specific statute, but excessive standing water, sewage, or flooding caused by plumbing leaks or inadequate drainage that contributes to mold is an 'imminently dangerous condition' the landlord must repair within a reasonable time after actual knowledge or notice. The general duty to keep the premises fit and habitable also applies. N.C. Gen. Stat. § 42-42(a)(2), (a)(8)(l) | No bed-bug statute. Rat infestation resulting from structural defects that leave the premises not impervious to rodents is an 'imminently dangerous condition' the landlord must remedy within a reasonable time; drainage problems contributing to mosquito infestation are also listed. The tenant must keep the unit clean and safe, avoid unsanitary conditions in common areas, and dispose of garbage properly. N.C. Gen. Stat. §§ 42-42(a)(2), (a)(8)(k)-(l); 42-43(a)(1)-(2) | Yes. The landlord must keep heating facilities in good and safe working order (after written notice of needed repairs, except emergencies), and lack of operable heating facilities capable of heating living areas to 65°F when it is 20°F outside, from November 1 through March 31, is an imminently dangerous condition requiring prompt repair. N.C. Gen. Stat. § 42-42(a)(4), (a)(8)(h) | No state requirement to provide air conditioning or a maximum indoor temperature. Air conditioning supplied or required to be supplied by the landlord must be kept in good and safe working order and promptly repaired after written notice (except emergencies). N.C. Gen. Stat. § 42-42(a)(4) |
| North Dakota | No statute — general habitability/repair duty applies. North Dakota has no mold disclosure, remediation or exposure-standard law for rentals; the landlord must comply with applicable building and housing codes affecting health and safety and 'make all repairs and do whatever is necessary to put and keep the premises in a fit and habitable condition.' N.D.C.C. § 47-16-13.1(1)(a)-(b) | No statute — no bed-bug or pest-specific law. The landlord's general duty to keep the premises fit and habitable and common areas clean and safe applies; the tenant must keep the unit as clean and safe as conditions permit, remove garbage, and not damage the premises. N.D.C.C. §§ 47-16-13.1(1)(b)-(c), 47-16-13.2 | Yes. The landlord must supply 'reasonable heat' and keep heating facilities it supplies in good and safe working order, unless the building is not required by law to be equipped for heat or the heat is generated by an installation under the tenant's exclusive control on a direct utility connection. No statewide minimum temperature or heating season is set. N.D.C.C. § 47-16-13.1(1)(d), (f) | No state requirement to provide air conditioning or a maximum indoor temperature. If the landlord supplies air conditioning, it must be maintained in good and safe working order. N.D.C.C. § 47-16-13.1(1)(d) |
| Ohio | No statute — general habitability/repair duty applies. Ohio has no mold disclosure, remediation or exposure-standard law for rentals; the landlord must comply with building, housing, health and safety codes and 'do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition.' Ohio Rev. Code § 5321.04(A)(1)-(2) | No statute — no bed-bug or pest-specific state law. The landlord must keep the premises fit and habitable and common areas safe and sanitary; the tenant must keep the part of the premises the tenant occupies safe and sanitary and dispose of garbage in a clean, safe and sanitary manner. Ohio Rev. Code §§ 5321.04(A)(2)-(3), 5321.05(A)(1)-(2) | Yes. The landlord must supply 'reasonable heat at all times' and keep landlord-supplied heating fixtures in good and safe working order, except where the building is not required by law to be equipped for heat or heat is generated by an installation in the tenant's exclusive control on a direct utility connection. No statewide minimum temperature or heating season. Ohio Rev. Code § 5321.04(A)(4), (6) | No state requirement to provide air conditioning or a maximum indoor temperature. Air-conditioning fixtures and appliances supplied by the landlord must be kept in good and safe working order. Ohio Rev. Code § 5321.04(A)(4) |
| Oklahoma | No statute — general habitability/repair duty applies. Oklahoma has no mold disclosure, remediation or exposure-standard law for rentals; the landlord must 'make all repairs and do whatever is necessary to put and keep the tenant's dwelling unit and premises in a fit and habitable condition.' 41 O.S. § 118(A)(2) | No statute — no bed-bug or pest-specific law. The landlord must keep the unit fit and habitable and (except single-family residences) keep common areas clean, safe and sanitary; the tenant must keep the occupied part of the premises as safe, clean and sanitary as its condition permits and dispose of garbage in a safe, clean and sanitary manner. 41 O.S. §§ 118(A)(1)-(2), 127(1)-(2) | Yes, except in single-family residences or where service comes through direct, independently metered utility connections to the unit: the landlord must supply 'reasonable heat' and running and hot water, and must keep landlord-supplied heating facilities in good and safe working order. No statewide minimum temperature or heating season. If the landlord willfully or negligently fails to supply heat, after written notice the tenant may terminate, procure heat and deduct the cost from rent, recover diminished rental value, or obtain substitute housing and be excused from rent. 41 O.S. §§ 118(A)(3), (A)(5), 121(C) | No state requirement to provide air conditioning or a maximum indoor temperature. If supplied by the landlord, air-conditioning must be maintained in good and safe working order. 41 O.S. § 118(A)(3) |
| Oregon | No mold-specific statute — the general habitability duty applies. A unit is unhabitable if it substantially lacks effective waterproofing and weather protection, plumbing in good working order, or floors, walls and ceilings in good repair, among other items. Mold is expressly excluded from the 'minor habitability defect' repair-and-deduct remedy (repairs up to $300), so tenants must use the other habitability remedies. ORS 90.320(1); ORS 90.368(1)(b) | No bed-bug-specific statute. At the start of the tenancy the landlord must deliver buildings and grounds free of rodents and vermin, and must keep areas under the landlord's control free of rodents and vermin. The tenant must keep areas under the tenant's control free of rodents and vermin to the extent the tenant caused the problem, and must reasonably cooperate with the landlord's efforts to remedy it. ORS 90.320(1)(f); ORS 90.325(1)(b) | Yes. A unit is unhabitable if it substantially lacks adequate heating facilities that conformed to applicable law when installed and are maintained in good working order. No statewide minimum indoor temperature or heating season. If the landlord deliberately or negligently fails to supply heat or other essential services, the tenant has remedies including procuring heat and deducting the cost, recovering damages, or obtaining substitute housing. ORS 90.320(1)(d); ORS 90.365 | Partly. For units in buildings whose construction permits were issued on or after April 1, 2024, the landlord must provide adequate cooling in at least one room (not a bathroom) — central air, a heat pump or a landlord-provided portable air conditioner. For all tenancies, a landlord generally may not prohibit a tenant from installing or using a portable air conditioner or evaporative cooler, subject to listed safety, building-code, electrical-capacity and window-installation exceptions; written restrictions must say whether the landlord will offer a community cooling space kept at no more than 80°F during extreme heat events. No state maximum indoor temperature for older buildings. ORS 90.320(1)(n); ORS 90.355 |
| Pennsylvania | No statute — Pennsylvania has no mold disclosure, remediation or exposure-standard law for rentals. Conditions such as mold are governed by the court-created implied warranty of habitability, which requires the landlord to keep the unit fit and habitable and to fix serious defects affecting safety or the ability to live there; the duty cannot be waived by the lease. Implied warranty of habitability (Pugh v. Holmes, 405 A.2d 897 (Pa. 1979)), as described in the PA Attorney General's Consumer Guide to Tenant and Landlord Rights | No statute — no state bed-bug or pest law for rentals. The Attorney General lists rodent infestation as an example of an uninhabitable condition under the implied warranty of habitability; the tenant must notify the landlord and allow a reasonable opportunity to fix it. Implied warranty of habitability (Pugh v. Holmes, 405 A.2d 897 (Pa. 1979)); PA AG Consumer Guide, Part IV.C | No state statute sets a heat requirement or minimum temperature for rentals. Lack of heat in winter is treated as an uninhabitable condition under the implied warranty of habitability. Implied warranty of habitability (Pugh v. Holmes, 405 A.2d 897 (Pa. 1979)); PA AG Consumer Guide, Part IV.C | No state requirement to provide air conditioning or a maximum indoor temperature. Landlord and Tenant Act of 1951, 68 P.S. § 250.101 et seq. (no provision) |
| Rhode Island | No statute — general habitability/repair duty applies. Rhode Island has no mold disclosure, remediation or exposure-standard law for rentals; the landlord must comply with building and housing codes affecting health and safety and 'make all repairs and do whatever is necessary to put and keep the premises in a fit and habitable condition.' R.I. Gen. Laws § 34-18-22(a)(1)-(2) | Under the state Housing Maintenance and Occupancy Code, the occupant of a single-unit dwelling is responsible for extermination of insects, rodents and other pests, and an occupant in a multi-unit building is responsible when only that occupant's unit is infested. The owner is responsible when the infestation is caused by the owner's failure to keep the building rodent-proof or reasonably insect-proof, and whenever two or more units or shared/public areas are infested. No bed-bug-specific statute. R.I. Gen. Laws § 45-24.3-6(i) | Yes. The landlord must supply reasonable heat as required by the state housing code (or stricter local code) between October 1 and May 1. Heating facilities must be capable of heating all habitable rooms, bathrooms and toilet compartments to at least 68°F, measured 18 inches above the floor, under average winter conditions. Exceptions: buildings not required to be equipped for heat, and units where the tenant controls a heating installation on a direct utility connection. R.I. Gen. Laws §§ 34-18-22(a)(6), 45-24.3-9(1) | No state requirement to provide air conditioning or a maximum indoor temperature. Landlord-supplied air-conditioning must be maintained in good and safe working order. R.I. Gen. Laws § 34-18-22(a)(4) |
| South Carolina | No statute — general habitability/repair duty applies. South Carolina has no mold disclosure, remediation or exposure-standard law for rentals; the landlord must comply with building and housing codes materially affecting health and safety and 'make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition.' S.C. Code § 27-40-440(a)(1)-(2) | No statute — no bed-bug or pest-specific law. The landlord's general duty to keep the premises fit and habitable applies; the tenant must keep the unit and the part of the premises the tenant uses reasonably safe and clean and dispose of garbage in a reasonably clean and safe manner. If the written lease conspicuously says so, the landlord may enter without consent between 9 a.m. and 6 p.m., after announcing intent, for regularly scheduled termite, insect or pest treatment. S.C. Code §§ 27-40-440(a)(2), 27-40-510(2)-(3), 27-40-530(b)(2) | Yes. The landlord must make available reasonable heat (and running and reasonable hot water) except where the building is not required by law to be equipped for heat or the heat is generated by an installation in the tenant's exclusive control on a direct utility connection, and must keep landlord-supplied heating facilities in reasonably good and safe working order. Heat is an 'essential service.' No statewide minimum temperature or heating season. S.C. Code §§ 27-40-440(a)(4)-(5), 27-40-210(17) | No state requirement to provide air conditioning or a maximum indoor temperature. If the landlord supplies air conditioning, it must be kept in reasonably good and safe working order; appliances in the unit are presumed landlord-supplied unless the rental agreement specifically excludes them. S.C. Code § 27-40-440(a)(5) |
| South Dakota | No statute — general habitability/repair duty applies. South Dakota has no mold disclosure, remediation or exposure-standard law for rentals; the landlord must keep the premises and common areas in reasonable repair, fit for human habitation and in good and safe working order, except for disrepair caused by the tenant's (or the tenant's invitees') negligent, willful or malicious conduct. SDCL 43-32-8 | No statute — no bed-bug or pest-specific law. The landlord's general duty to keep the premises fit for human habitation applies, except where the condition was caused by the tenant's negligent, willful or malicious conduct. SDCL 43-32-8 | The landlord must maintain heating systems in good and safe working order (unless the tenant caused the disrepair) and keep the unit fit for human habitation. No state statute sets a minimum indoor temperature or heating season. SDCL 43-32-8 | No state requirement to provide air conditioning or a maximum indoor temperature. SDCL ch. 43-32 (no provision) |
| Tennessee | No statute — Tennessee's landlord-tenant law sets no mold disclosure or remediation rule. In counties covered by the Uniform Residential Landlord and Tenant Act, mold falls under the landlord's general duties to comply with building and housing codes materially affecting health and safety and to make all repairs needed to keep the premises fit and habitable. The tenant must keep the unit as clean and safe as when the tenant took possession. T.C.A. § 66-28-304(a); § 66-28-401 | No statute — no pest or bed-bug provision in the landlord-tenant law. In URLTA counties, infestations fall under the landlord's code-compliance and fit-and-habitable duties; the tenant must keep the unit clean and safe, dispose of garbage properly, and comply with tenant obligations under housing codes. T.C.A. § 66-28-304(a); § 66-28-401(1)-(3) | No minimum temperature or heating season in state law. In URLTA counties, heat is an 'essential service': if the landlord deliberately or negligently fails to supply it, the tenant, after written notice, may procure heat and deduct the actual reasonable cost from rent, recover damages for reduced rental value, or obtain substitute housing (rent excused) and recover its reasonable value plus attorney's fees. The remedy is unavailable if the tenant, family or guests caused the condition. T.C.A. § 66-28-502(a), (c); § 66-28-304(a)(1)-(2) | No statute — Tennessee law does not require air conditioning or set a maximum indoor temperature. If the landlord supplies air conditioning, a failure that materially affects health and safety may be treated under the general repair duty or the 'essential services' remedy (which covers obligations materially affecting health and safety) in URLTA counties. T.C.A. § 66-28-304; § 66-28-502(a)(3) |
| Texas | No landlord-tenant mold statute — Texas law sets no mold disclosure or mold-specific remediation duty for residential landlords. Mold is handled under the general duty to repair: after written notice from a tenant who is current on rent, the landlord must make a diligent effort to repair a condition that materially affects the physical health or safety of an ordinary tenant. Separately, the Occupations Code licenses professional mold assessors and remediators; an owner of residential property with fewer than 10 units (or its employee) may do its own mold assessment or remediation without a license. Tex. Prop. Code Sec. 92.052; Tex. Occ. Code ch. 1958 (Sec. 1958.102) | No statute — the Property Code has no pest or bed-bug provision (no disclosure, inspection or treatment rule). An infestation is treated under the general repair duty if it materially affects the physical health or safety of an ordinary tenant and the tenant gave notice; the landlord has no duty to remedy conditions caused by the tenant, household or guests. Leases commonly allocate pest-control responsibility. Tex. Prop. Code Sec. 92.052 (ch. 92 checked) | No statewide heat or minimum-temperature requirement. State law requires only a device supplying hot water of at least 120 degrees F. If the landlord agreed (expressly or impliedly) to furnish heating equipment that produces inadequate heat, and a local housing, building or health official has notified the landlord in writing that the lack of heat materially affects health or safety, the tenant may use the repair-and-deduct remedy if the landlord fails to repair within 3 days after the tenant's notice. Tex. Prop. Code Sec. 92.052(a)(3)(B); 92.0561(d)(3)(C) | No statewide air-conditioning requirement or maximum indoor temperature. If the landlord agreed in the lease to furnish cooling equipment that is producing inadequate cooled air, and a local official has notified the landlord in writing that the lack of cooling materially affects health or safety, the tenant may repair and deduct if the landlord fails to repair within 3 days after notice. A landlord that submeters or allocates electricity may not cut off a tenant's electricity for nonpayment during a National Weather Service heat advisory for the county (that day or either of the two preceding days). Tex. Prop. Code Sec. 92.0561(d)(3)(C); 92.008 |
| Utah | No statute — the Utah Fit Premises Act does not mention mold. Mold is governed by the general duty to keep the unit fit for human habitation and in accordance with local ordinances and local board of health rules, and not to rent premises unless they are safe, sanitary and fit for human occupancy. The act applies only to conditions that materially affect the physical health or safety of the ordinary renter. Utah Code 57-22-3; 57-22-4(1); 57-22-6 | No statute — no pest or bed-bug provision in the Fit Premises Act. Infestations fall under the safe-and-sanitary duty and local health-department rules when they materially affect health or safety. The renter must keep the unit clean and safe, dispose of garbage properly, and comply with local board of health rules. Utah Code 57-22-3; 57-22-4(1); 57-22-5(1) | Yes. Each rental unit must have heating (along with electrical systems, plumbing and hot and cold water), and the owner must maintain the heating system. State law sets no minimum indoor temperature or heating season; local ordinances and board of health rules may. Utah Code 57-22-3(1); 57-22-4(1) | No duty to install air conditioning and no maximum indoor temperature. If the unit has an air conditioning system, the owner must maintain it in an operable condition. Utah Code 57-22-4(1) |
| Vermont | No mold-specific statute, but the state Rental Housing Health Code requires every rental unit to be kept free from the regular or periodic appearance of standing water or excessive moisture that may result in visible mold growth, and bars use of humidifiers in ways that raise relative humidity above 60%. The landlord's statutory warranty of habitability requires premises that are safe, clean, fit for habitation and compliant with building, housing and health regulations; the warranty cannot be waived. 9 V.S.A. § 4457(a)-(b); Vermont Rental Housing Health Code §§ 8.2, 10.3 | Yes, by health code. The owner must keep common spaces free from infestation (pests or bed bugs) and exterminate there, and must exterminate inside a unit when the infestation is caused by the owner's failure to maintain the building or exists in two or more units. Rooming-house owners are responsible for all rooms. The tenant must keep the unit free from infestation and pay for extermination when the infestation is caused by the tenant's failure to maintain the unit (except where the owner is responsible as above). Extermination must remove harborage and food sources and use treatments such as spraying, fumigating, heat treating or trapping. Vermont Rental Housing Health Code §§ 4.7, 4.15, 6.1-6.3 | Yes. The landlord must ensure heating facilities capable of safely providing a reasonable amount of heat, and a landlord who provides heat under the lease must supply a reasonable amount at all times (summer rentals and hunting camps excepted). The Rental Housing Health Code requires heating facilities whenever the outside temperature is below 55 degrees F, able to maintain at least 65 degrees F in all habitable rooms, kitchens and bathrooms (measured 3 feet above the floor and 3 feet from an exterior wall) without overheating one room to heat another; unvented fuel-fired space heaters are prohibited. 9 V.S.A. § 4457(c); Vermont Rental Housing Health Code §§ 7.1-7.5 | No statute — Vermont law and the Rental Housing Health Code do not require air conditioning or set a maximum indoor temperature. The code requires ventilation to the outdoors and screens on operable windows. 9 V.S.A. ch. 137 (checked); Vermont Rental Housing Health Code § 8.1 |
| Virginia | Yes — detailed statute. Disclosure: the move-in inspection report must state whether there is visible evidence of mold in readily accessible interior areas; a 'no visible mold' statement is deemed correct unless the tenant objects in writing within 5 days. If mold is disclosed, the tenant may terminate and not take (or keep) possession, or take possession and have the landlord remediate within 5 business days, reinspect and issue a new report. Duty: the landlord must maintain the premises to prevent moisture accumulation and mold growth, respond promptly to tenant notices, and promptly remediate visible mold to professional standards, reinspect, and give the tenant a summary of remediation information. Where mold materially affects health or safety, the landlord may relocate the tenant for up to 30 days to a comparable unit or hotel at no cost to the tenant (rent continues). Tenants must use reasonable efforts to prevent moisture and mold and promptly report it. Va. Code § 55.1-1215; § 55.1-1220(A)(5); § 55.1-1227(A)(10); § 55.1-1231 | The landlord's general duty to keep the premises fit and habitable and to comply with housing codes applies. The tenant must keep the part of the unit the tenant occupies free from insects and pests and promptly notify the landlord of them, and is financially responsible for added treatment costs caused by unreasonable delay in reporting and for treatment costs caused by the tenant's fault in failing to prevent infestation. The landlord must give at least 48 hours' written notice before applying insecticide or pesticide in a unit (unless the tenant requested it or agrees to less), post notice for common-area applications, and the tenant must prepare the unit per the landlord's written instructions. Va. Code § 55.1-1220(A)(1)-(2); § 55.1-1227(A)(3), (14); § 55.1-1223 | Yes. The landlord must supply heat in season (unless heat is generated by equipment within the tenant's exclusive control or supplied by a direct public utility connection) and keep heating facilities in good and safe working order. Heat is an 'essential service'; if the landlord willfully or negligently fails to supply it, the tenant may give written notice and, after a reasonable time to correct, pursue statutory remedies (such as damages for reduced rental value). State law sets no minimum temperature or dates for the heating season; local codes may. Va. Code § 55.1-1220(A)(4), (7); § 55.1-1200 ('essential service'); § 55.1-1239 | No duty to install air conditioning, but if air conditioning is provided the landlord must supply reasonable air conditioning and keep it in good and safe working order. Central air conditioning supplied by the landlord and operating (or represented as operating) when the lease takes effect is an 'essential service' so a willful or negligent failure to supply it triggers the same tenant remedies. State law sets no maximum indoor temperature. Va. Code § 55.1-1220(A)(4), (7); § 55.1-1200; § 55.1-1239 |
| Washington | Disclosure required: the landlord must give tenants information provided or approved by the Department of Health about the health hazards of indoor mold and how tenants can control mold growth, either in writing to each tenant or posted in a visible public location on the property. The landlord is immune from civil liability for failing to do so unless the failure is knowing and intentional. There is no mold-specific remediation standard; mold is handled under the landlord's general duty to keep the premises fit for habitation, comply with health and safety codes and make repairs. RCW 59.18.060(1), (5), (14), (15) | The landlord must provide a reasonable program for the control of insects, rodents and other pests at the start of the tenancy and, except in a single-family residence, must control infestation during the tenancy unless the tenant caused it. No bed-bug-specific statute (no disclosure or inspection rule). The tenant must pay all extermination and fumigation costs for an infestation the tenant caused. RCW 59.18.060(4); 59.18.130(2) | Yes. The landlord must provide facilities adequate to supply heat (and water and hot water) as reasonably required by the tenant, and keep heating facilities it supplies in reasonably good working order. After notice, a defect depriving the tenant of heat must be remedied within 24 hours (where possible). State law sets no minimum indoor temperature or heating season. RCW 59.18.060(8), (11); 59.18.070(1) | No duty to provide air conditioning and no maximum indoor temperature. Since 2026, a landlord generally may not prohibit or restrict a tenant from installing a portable cooling device (air conditioner or portable heat pump) and may not charge a fee for its use, inspection or installation. Exceptions: the unit already has a permanent, fully operational heat pump; installation would violate codes or manufacturer safety guidelines, cause unreasonable damage, or exceed the electrical supply; and window units may be restricted for egress, lock, mounting, security or written insurance-policy reasons (which must be disclosed in the lease). The tenant must give 2 days' notice before installing a window unit. Also, a landlord may not cut off electric or water service for nonpayment on a day the National Weather Service has issued a heat-related alert for the area. RCW 59.18.740; 59.18.060(11)(a) |
| West Virginia | No statute — West Virginia's landlord-tenant law does not mention mold and sets no disclosure or remediation rule. Mold is governed by the general duty to deliver and maintain the unit in a fit and habitable condition, to meet applicable health, safety, fire and housing codes, and to make repairs needed to keep it habitable — unless the problem was caused by the tenant, family or guests' lack of reasonable care. The landlord need not make repairs while the tenant is behind on rent. W. Va. Code § 37-6-30(a)(1)-(2), (4), (c) | No statute — no pest or bed-bug provision in the landlord-tenant chapter. Infestations are handled under the fit-and-habitable duty and applicable health and housing codes; the landlord's duty does not extend to conditions caused by the tenant, family members or guests, or to repairs while rent is in arrears. W. Va. Code § 37-6-30 | Yes. For units served by direct public utility connections, the landlord must supply reasonable heat between October 1 and the last day of April (plus running water and reasonable hot water at all times), unless heat is generated by an installation within the tenant's exclusive control. The landlord must also keep heating facilities it supplies in good and safe working order. No minimum temperature is set by state law. W. Va. Code § 37-6-30(a)(5), (a)(7) | No duty to provide air conditioning and no maximum indoor temperature. If air conditioning is supplied (or required by agreement or law), the landlord must maintain it in good and safe working order. W. Va. Code § 37-6-30(a)(5) |
| Wisconsin | No statute — neither Wis. Stat. ch. 704 nor the rental-practices rule (ATCP 134) mentions mold. Mold is handled under the general repair duty (structural repairs, keeping equipment and landlord-controlled areas in repair, complying with any local housing code) and the pre-lease disclosure rule: before signing or taking a deposit, the landlord must disclose known uncorrected code violations that significantly threaten health or safety, and conditions that are a substantial hazard to the tenant's health or safety. A tenant may also use the untenantability remedies if the premises become unfit for occupancy. Wis. Stat. 704.07(2), (4); Wis. Admin. Code ATCP 134.04(2) | No bed-bug-specific statute. If the premises are damaged by an infestation of insects or other pests caused by the tenant's acts or inaction, the landlord may let the tenant remediate or may do the work itself and charge the tenant the reasonable cost (materials, labor, and the landlord's time at a reasonable hourly rate). Infestations not caused by the tenant fall under the landlord's general repair and local housing-code duties. Wis. Stat. 704.07(2), (3)(a) | Partly. The landlord must keep in reasonable repair any equipment it has expressly or impliedly agreed to provide to supply heat, and must comply with any local housing code. Before renting, the landlord must disclose if the heating facilities are not in safe operating condition or cannot maintain at least 67 degrees F (measured at the center of the room, midway between floor and ceiling) in all living areas during all seasons the unit may be occupied. Wis. Stat. 704.07(2)(a)2., 5.; Wis. Admin. Code ATCP 134.04(2)(b)2. | No state requirement to provide air conditioning and no maximum indoor temperature. If the landlord has expressly or impliedly agreed to provide air conditioning, it must keep that equipment in a reasonable state of repair. Wis. Stat. 704.07(2)(a)2. |
| Wyoming | No statute — Wyoming's Residential Rental Property Act does not mention mold, and no state housing code addresses it. Mold is governed only by the general duty to keep the unit safe, sanitary and fit for human habitation; the act applies only to conditions that materially affect the physical health or safety of the ordinary renter. The renter must be current on payments and give written notice (certified mail or as allowed by W.S. 1-21-1003) before court remedies are available. W.S. 1-21-1202(a), (c); 1-21-1203(a)-(b); 1-21-1206 | No statute — no pest or bed-bug provision in the Residential Rental Property Act or elsewhere for rentals. Infestations fall under the general safe-and-sanitary duty if they materially affect health or safety. The owner need not remedy conditions caused by the renter, the renter's family or guests through misuse, and the renter must keep the unit clean and dispose of garbage properly. W.S. 1-21-1202; 1-21-1203(c); 1-21-1204(a)(i)-(ii) | Yes, but no temperature standard. Each rental unit must have operational heating (and electrical, plumbing and hot and cold running water) unless both parties agree otherwise in writing, and the owner must maintain the heating system. State law sets no minimum indoor temperature or heating season. Seasonal units such as summer cabins not intended to have these amenities are excepted. W.S. 1-21-1202(a); 1-21-1203(a)(iii) | No statute — Wyoming law does not require air conditioning or set a maximum indoor temperature. If the rental agreement specifically provides air conditioning, the owner must maintain it as a contracted appliance or facility. W.S. 1-21-1203(a)(iv) |
