Regulatory framework
The code baseline for Grand Traverse County.
The department publishes the 2021 Michigan Building Code, 2021 Rehabilitation Code, 2021 Michigan Energy Code, 2023 Michigan Electrical Code, 2021 Michigan Mechanical Code, and 2021 Michigan Plumbing Code. Its notice also states that the 2015 Michigan Residential Code and 2015 Residential Energy Code remain in effect until further notice while the state's residential-code update is under review. The county has construction-code authority except in local units that have designated their own agency; the statewide list identifies Traverse City as local and Garfield Township as local for building, electrical, and plumbing, with county enforcement for most other listed units.
