Michigan Electrician Legislation, Codes, and Guidelines
Michigan Electrician Building Codes and Legislation
Michigan has adopted the 2023 National Electrical Code (NEC) as its state-level electrical code, effective March 12, 2024. This adoption is part of Michigan's broader adoption of updated mechanical, plumbing, and electrical codes. The state's electrical code is primarily governed by Part 8 of the Michigan Administrative Code.
It's important to note that the newly adopted National Electric Code in Michigan does not include one- and two-family homes. Instead, it focuses on multi-family dwellings, such as nursing homes, police and fire stations, and university dormitory units. However, Michigan also has a separate, more outdated residential electrical code that is expected to be updated to align more closely with the 2023 National Electric Code in the future.
Key changes introduced with the 2023 NEC in Michigan include requirements for an emergency electrical shut-off on the exterior of new homes or existing homes with new electrical services, and the mandatory installation of whole-house surge protectors in every breaker panel for new or updated electrical services.
The primary state board responsible for setting and overseeing these standards is the Michigan Department of Licensing and Regulatory Affairs (LARA), specifically through its Bureau of Construction Codes (BCC). The Electrical Administrative Board, created by 2016 PA 407, also plays a role by making recommendations for electrical code rules, granting licenses, and establishing necessary regulations.
