Do I need a permit for window or exterior door replacement in Novi?

Permit likely required

Most likely yes. Window or exterior door replacement usually requires a permit in Michigan. Confirm the specifics with Novi.

Window and door replacement is not on Michigan's list of work exempt from permit (R 408.30505); only work the enforcing agency accepts as an ordinary repair is exempt under MCL 125.1510(7). Cutting or enlarging openings, changing headers, or changing a required emergency escape opening goes beyond ordinary repair and needs a permit. Replacement windows and doors must meet the residential energy provisions of the Michigan Residential Code; glass-only replacement in an existing sash and frame is exempt from those provisions.
