What building code does Detroit, MI use?
Detroit, MI currently enforces the 2021 Michigan Building Code (state-amended 2021 IBC). Detroit enforces the state-adopted code. Statewide LARA codes enforced locally by Detroit BSEED: the 2021-based Michigan Building/Rehabilitation Codes took effect April 9, 2025 and the 2023 NEC and 2021 MMC/MPC on March 12, 2024, but a July 7, 2025 Michigan Court of Claims order (Home Builders Assoc. v. LARA) blocks the 2021-based Residential and residential Energy rule sets, leaving the 2015 versions in force; no separately confirmed model fire code edition for Detroit (Fire Marshal enforces the city fire ordinance plus NFPA standards), so the fire category is omitted.
