The rules in Ohio
| Mold | 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.' If the landlord fails to fix a condition within a reasonable time (not more than 30 days) after written notice, the tenant may use the rent-deposit-with-court remedy in § 5321.07. Local housing or health codes may address mold. |

| Pests & bed bugs | 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. No state bed-bug disclosure or inspection rule. Responsibility for treatment generally follows the habitability duty and the lease; local codes may assign pest-control duties.

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. Municipal housing codes (e.g., in larger cities) may set specific minimum temperatures. |
| Air conditioning | 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. Source: Ohio Rev. Code § 5321.04(A)(4) |

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.

| 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.

| 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) |
| 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 |
| 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) |
