Exemptions: Michigan enforces a statewide Michigan Residential Code (MRC) promulgated by LARA's Bureau of Construction Codes (Mich. Admin. Code R 408.30500 series). Building permits are required for construction, alteration, and demolition except for the specific items exempted in MRC R105.2 as amended by R 408.30505 (e.g., 200 sq ft accessory structures, 7 ft fences, 4 ft retaining walls, finish work, sidewalks/driveways under 30 in). Local jurisdictions administer the code and may have additional requirements.
Exemptions: Most decks require a building permit; Michigan Residential Code R105.2 (Mich. Admin. Code R 408.30505(a)(x)) exempts only decks, porches, patios, landings, or similar structures not exceeding 200 square feet (18.58 m2), not more than 30 inches (762 mm) above grade at any point, not attached to a dwelling or its accessory structures, not within 36 inches (914 mm) of a dwelling or its accessory structures, and not serving any ingress or egress door. Any attached deck or a deck exceeding these limits needs a permit. Local jurisdictions may amend, so verify locally.
Exemptions: Electrical work generally requires a permit under the Michigan Electrical Code (R 408.30801 to R 408.30880); Michigan Residential Code R105.2 (Mich. Admin. Code R 408.30505(b)) exempts only minor repair work (replacing lamps or connecting approved portable equipment to permanently installed receptacles), electrical equipment used for radio and television transmissions, and temporary systems for testing or servicing electrical equipment. New circuits, panel changes, and rewiring require permits. Local enforcing agencies may amend administrative procedures.
Exemptions: A fence that is not more than 7 feet (2,134 mm) high is exempt from a building permit under Michigan Residential Code R105.2 as amended by Mich. Admin. Code R 408.30505(a)(ii). Fences taller than 7 feet require a permit. Local zoning ordinances commonly impose stricter height limits (often 4-6 ft), so check the local jurisdiction.
Exemptions: Reroofing/roof replacement is not listed among the work exempt from permit in Michigan Residential Code R105.2 as amended by Mich. Admin. Code R 408.30505, so a building permit is generally required for residential roof replacement in Michigan. Only ordinary repairs and finish work (painting, papering, tiling, carpeting, cabinets, countertops) are exempt. Local enforcing agencies administer permits and may have their own application procedures.
Exemptions: A retaining wall not more than 4 feet (1,219 mm) in height, measured from the bottom of the footing to the top of the wall, is exempt from a building permit unless it supports a surcharge, per Michigan Residential Code R105.2 as amended by Mich. Admin. Code R 408.30505(a)(iii). Walls over 4 feet or any wall supporting a surcharge (e.g., sloped backfill, driveway, or structure above) require a permit. Local jurisdictions may amend this threshold.
Exemptions: No building permit is required for a one-story detached accessory structure if the floor area does not exceed 200 square feet (18.58 m2), per Michigan Residential Code R105.2 as amended by Mich. Admin. Code R 408.30505(a)(i). Larger sheds or sheds with more than one story require a permit. Local jurisdictions may add zoning/setback requirements, so confirm with the local building department.
Exemptions: Water heater replacement is not exempt: Michigan Residential Code R105.2 (Mich. Admin. Code R 408.30505(d)) exempts only the stopping of leaks and the clearing of stoppages/repair of leaks in pipes, valves, or fixtures without replacement or rearrangement of valves, pipes, or fixtures, so installing or replacing a water heater requires a plumbing (and, for gas units, mechanical) permit. Mechanical exemptions cover only portable appliances under 30,000 BTU/hr and minor part replacement. Local jurisdictions issue the permits, so confirm requirements locally.
