Kent County
Converting a Wyoming garage into habitable space (a bedroom, in-law suite, home office, or ADU) requires both (1) zoning approval under the Wyoming Zoning Ordinance for the change of use, because the converted space is no longer accessory parking and may count toward floor area, trigger ADU classification, or affect the underlying district's parking minimums; and (2) a building permit under the Michigan Single State Construction Code (MCL 125.1501 et seq.) administered locally by the Wyoming Building Official. Converted habitable space must meet the Michigan Residential Code provisions adopted from the IRC, including emergency egress (IRC R310), minimum ceiling height (IRC R305), smoke and carbon monoxide alarms (IRC R314/R315), and light/ventilation (IRC R303).

Grand Rapids FAQ
Can I convert my garage into a living space in Grand Rapids?
Yes, with a building permit. The space must meet building code standards for habitable rooms. Check zoning requirements for replacement parking. ADU conversions within garages are possible under ADU regulations.
Do I lose my parking space when I convert my Grand Rapids garage?
Possibly. The zoning ordinance requires a minimum number of off-street parking spaces per dwelling. You may need to add replacement parking depending on the district.
Can I convert my Grand Rapids garage into an Airbnb or rental unit?
ADU conversions within garages follow the city's ADU regulations, which include specific standards. STR use also requires compliance with the short-term rental rules.
Wyoming FAQ
Can I convert my garage to a bedroom in Wyoming, MI?
Possibly, but you need both a zoning approval from the Wyoming Department of Community and Economic Development under the Wyoming Zoning Ordinance and a building permit from the Wyoming Building Official under the Michigan Single State Construction Code (MCL 125.1513). The converted space must meet the Michigan Residential Code including R310 egress windows, R305 ceiling height, and R314/R315 smoke and CO alarms. Loss of garage parking may also conflict with Wyoming Zoning parking standards.
Does a garage conversion count as an ADU in Wyoming?
It depends on the resulting use. If the converted garage becomes a self-contained dwelling unit with its own kitchen, bathroom, and entrance, Wyoming will treat it as an ADU and apply district-specific rules under the Wyoming Zoning Ordinance. Michigan has no statewide ADU preemption (unlike California or Oregon), so Wyoming's local zoning rules control entirely.
