The rules in Idaho
| Mold | 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. Before suing under § 6-320, the tenant must give the landlord 3 days' written notice listing each problem and demanding cure (§ 6-320(d)). The Department of Health and Welfare's Indoor Environment Program provides education only. |
|---|---|
| Pests & bed bugs | 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. The lease may allocate routine pest control; local housing codes may add requirements. |
| Heat | 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. Separately, Public Utilities Commission rules bar regulated utilities from shutting off gas or electric heat for nonpayment in December–February for households with children, elderly, or ill members (AG Manual, p. 16); this binds utilities, not landlords. |
| Air conditioning | 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. The 3-day written notice and cure requirement in § 6-320(d) applies. Source: Idaho Code § 6-320(a)(2) |
| Smoke and CO detectors | Landlords must install approved battery-operated smoke detectors in each dwelling unit they control, including mobile homes, and must verify at the start of the rental that they are installed and working. The tenant must keep them in good working order during the tenancy. If the landlord fails to install working detectors, the tenant may send a certified-mail notice and, if they are not installed within 72 hours of receipt, install them and deduct the cost from the next month's rent; the detectors then belong to the landlord. No Idaho carbon monoxide detector rule for rentals was verified. Source: Idaho Code § 6-320(a)(6) |

| 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) |
| 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 |
| 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 |
| 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) |
| 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) |
| 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) |
