Wyoming, MI Rental Property Rules: Repairs & Habitability (2026)

WPMC Sec. 2 requires dwellings to be equipped with heating facilities capable of maintaining 68°F in all habitable rooms, bathrooms, and toilet rooms, measured against the winter outdoor design temperature for the locality listed in Appendix D of the Michigan Building, Residential, or Plumbing Codes; cooking appliances and portable unvented fuel-burning space heaters cannot be used as the means of providing that heat, and portable space heaters generally cannot be used to achieve compliance. Sec. 3 turns that standard into a landlord duty: any owner or operator who rents or leases a dwelling or sleeping unit and undertakes to furnish heat must maintain the Sec.

2 temperatures, with two exceptions, when outdoor temperatures fall below the winter design temperature and the heating system is running at full capacity, and where the average monthly temperature is above 30°F, when a 65°F minimum applies instead. The requirement is tied directly to Wyoming's rental registration program: Sec. 4 requires an owner to register any rental unit with the code official, pass an inspection confirming WPMC compliance, and pay applicable fees before renting, leasing, or offering the unit for rent. Under Sec. 4(c), HVAC or heating malfunctions found during that inspection or within the prior two years shorten the registration term, from four years to two for smaller properties, or from two years to one for buildings with four or more units. The code official within the Department of Community and Economic Development, designated under Sec. 1, enforces the standard.
