Wyoming, MI Accessory Structures: ADU Owner Occupancy (2026)

Sec. 90-334 of the Wyoming Zoning Ordinance, adopted by Ordinance No. 3-25 on January 21, 2025, defines an accessory dwelling unit (ADU) as a house or apartment that shares a building lot with, and is incidental to, a larger primary dwelling unit. Subsection (1)(b) states that any ADU that is not owner-occupied is subject to rental/housing inspections, meaning that once the property owner no longer lives in either the primary home or the ADU and instead rents the accessory unit to a tenant, the unit falls under the city's rental housing inspection program administered through the housing inspector's office referenced in Sec.

1-27. That inspection obligation applies on top of the section's other conditions: the ADU must be one of no more than one per lot, sit within or attached to the primary structure, hold no more than one bedroom, and provide its own dedicated off-street parking space. The owner-occupancy inspection trigger works alongside the separate short-term-rental ban in subsection (1)(c), which independently bars renting the ADU short-term regardless of who occupies the primary home. Property owners who plan to rent an ADU on a standard lease, rather than live in it or the primary dwelling themselves, should expect a rental housing inspection before or during that tenancy, consistent with how the city treats other non-owner-occupied rental housing in single-family districts.
