Deck Construction Permits in Detroit
Local Rule
City of Detroit Buildings, Safety Engineering and Environmental Department (BSEED)
Detroit follows the statewide Michigan exemption, which carries a genuinely distinctive local twist beyond the standard national model: under Mich. Admin. Code R 408.30505(x), a deck, porch, patio or landing is exempt from a permit only if it is 200 square feet or less, no more than 30 inches above grade, not attached to the dwelling or its accessory structures, sits at least 36 inches away from the dwelling or any accessory structure, and does not serve an ingress or egress door. A freestanding deck placed close to the house, even if small and low, still fails that 36 inch clearance test and needs a permit. Michigan's statewide frost depth requirement is 42 inches, which Detroit enforces for deck footings.

How This Compares to Wayne County
Detroit's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:
Michigan LARA (state mandate) + city/township building department
Under 2015 MRC R105.2, a deck is exempt only if ALL of the following are true: 200 sq ft or less, no point more than 30 inches above grade, and, distinctively narrower than most states, completely detached and at least 36 inches from any structure (not merely "unattached"), meaning even a small floating deck placed close to the house still requires a permit. Michigan's planned 2021 MRC update (originally set for August 29, 2025) remains delayed by litigation as of April 2026, so the 2015 code stays in force statewide, administered locally per township/city.
