Do I need a permit for basement finishing in Byron Township?
Yes. In Michigan, basement finishing generally requires a permit, and Byron Township is no exception.
Framing new walls and adding wiring are not on Michigan's list of work exempt from permit (R 408.30505), and LARA states any addition to electrical conductors needs an electrical permit. When permitted alterations occur or a sleeping room is added, the home must get smoke alarms in the locations required for new dwellings, including the basement level (R 408.30546). Carbon monoxide alarms are required when permitted work occurs in a home with an attached garage or fuel-fired appliance (R 408.30520). Exposed wall and floor cavities must be insulated to the energy code (R 408.30547c), and Michigan allows a Class III or no vapor retarder on the interior side of below-grade walls (R 408.30522a).
