The rules in Utah
| Mold | 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. The renter's remedies (repair-and-deduct or rent abatement, or termination) require written notice and a reasonable time to correct (57-22-6). Duties may be reallocated by an explicit written agreement signed by both parties (57-22-3). |
|---|---|
| Pests & bed bugs | 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. Local health department regulations may address infestations. |
| Heat | 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. Source: Utah Code 57-22-3(1); 57-22-4(1) |
| Air conditioning | 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. Failure of air conditioning is a 'deficient condition' for remedy purposes only if it materially affects the physical health or safety of the ordinary renter. Source: Utah Code 57-22-4(1) |

| 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 |
| 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) |
| 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 |
| 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 |
| 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.

NMSA 1978, § 47-8-20(A)(4), (A)(6) |
| 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) |
