The rules in Michigan
| Mold | 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 125.471: https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-125-471. The Housing Law applies in cities, villages and townships of 10,000 or more people, but not to single- and two-family homes in places under 100,000 unless locally adopted (MCL 125.401). The § 554.139 covenants may be modified only in leases with a current term of at least 1 year. |

| Pests & bed bugs | 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. Where the Housing Law of Michigan applies, occupants can sue the owner over unabated unsanitary conditions after notice (MCL 125.536): https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-125-536. Source: MCL 554.139(1) |
| Heat | 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. Housing Law coverage depends on municipal population (MCL 125.401): https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-125-401. Source: MCL 125.471; MCL 554.139(1) |
| Air conditioning | 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. Local codes may address cooling equipment. |

| Ohio | No statute — general habitability/repair duty applies.

| 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. |
