Do I need a permit for garage conversion in Unincorporated Berrien County?
Unincorporated Berrien County does not issue residential building permits. Berrien County has no county construction code program. The State of Michigan Bureau of Construction Codes Statewide Jurisdiction List (Rev. 8/21/2026) lists the cities, villages and townships in the county as running their own building programs, except the Village of Galien and Weesaw Township, where the State Bureau of Construction Codes enforces building (Building Trades Section 517-241-9313). Homeowners apply to their own city, village or township.
The requirements below come from Michigan rules and describe the standard the work must still meet. They are not a statement that Unincorporated Berrien County will issue you a permit.
Yes. In Michigan, garage conversion generally requires a permit, and Unincorporated Berrien County is no exception.
LARA states a permit is required when the use or occupancy of a structure or any part of it is changed, which includes turning a garage into living space. Alterations must meet the energy code provisions for new construction (N1101.3.1 as amended in R 408.30547c), so the new living space must be insulated to code. When a sleeping room is created, the home must get smoke alarms in the locations required for new dwellings (R 408.30546), and carbon monoxide alarms are required where there is an attached garage or fuel-fired appliance (R 408.30520). If part of the garage stays a garage, Michigan does not allow any opening from it directly into a sleeping room (R 408.30544b).
