Michigan Roofing Legislation, Codes, and Guidelines
Michigan Roofing Legislation and Building Codes
Roofing projects in Michigan are governed by the state's construction codes, which are based on national model codes with specific state-level amendments. The primary regulations for residential roofing are found within the Michigan Residential Code (MRC), while commercial and larger structures fall under the Michigan Building Code (MBC). These codes establish essential requirements for roof assemblies, including material standards, fire classification, ice barrier installation, and limitations on the number of roofing layers allowed.
Primary State Agencies
The administration and enforcement of building codes in Michigan are overseen by the Department of Licensing and Regulatory Affairs (LARA). Within LARA, the Bureau of Construction Codes (BCC) is the specific division responsible for developing, administering, and enforcing the Michigan Building Code and the structural provisions of the Michigan Residential Code. While the state sets these overarching standards, local municipalities and building departments are responsible for local enforcement, permit issuance, and inspections, and they may impose additional requirements or stricter standards within their jurisdictions.
