Most renovation work in Wayne County requires a permit for structural, electrical, plumbing, and mechanical changes. Detroit requires construction documents sealed by a licensed architect or engineer. Cosmetic work does not require permits.
Detroit BSEED requires building permits for structural modifications, electrical work, plumbing changes, HVAC installation, window/door modifications, roofing, and additions. Construction documents must include the seal and signature of a licensed architect or professional engineer on all pages. Three complete sets of construction drawings, one set of calculations, and one complete set of specifications are required. Review typically takes 1-3 business days for standard projects. Cosmetic work (painting, flooring, cabinets) does not require a permit. Detroit's historic districts may require additional review by the Historic District Commission. The Michigan Residential Code and 2019 Detroit City Code apply.
Unpermitted work results in stop-work orders, fines, and required retroactive permits. Work without licensed professional documents may require additional engineering review.
