Regulatory framework
The code baseline for Branch County.
Current Michigan codes identified by LARA for 2026: 2021 Michigan Building Code (effective April 9, 2025); 2015 Michigan Residential Code (current code, effective February 8, 2016, with later 2021 residential rules held by court order); 2021 Michigan Rehabilitation Code; 2021 Michigan Mechanical Code; 2021 Michigan Plumbing Code; 2023 National Electrical Code/Michigan Electrical Code (effective March 12, 2024); and 2021 Michigan Commercial Energy Code (effective April 22, 2025). Branch County’s website still displays some older code labels, including 2015 commercial building, 2015 energy and 2017 electrical references, so applicants should confirm the code edition applied to the permit with the department.
