State-Level Building Codes for Roofing in Montana
The State of Montana enforces building standards through the adoption of the International Code Council (ICC) series of codes. As of the current code cycle, the state has adopted the 2021 editions of the International Building Code (IBC) and the International Residential Code (IRC). These model codes are incorporated by reference into the Administrative Rules of Montana (ARM), specifically within Title 24, Chapter 301. It is important to note that the "Montana Building Code" consists of these model codes as amended by the state to address specific regional needs, such as snow loads and energy efficiency requirements. These state-specific amendments supersede the language found in the base model codes.
Primary State Agency for Building Standards
The primary agency responsible for setting and enforcing these standards at the state level is the Building Codes Program, which operates under the Building & Commercial Measurements Bureau within the Montana Department of Labor & Industry. This bureau is responsible for adopting the uniform state building code and overseeing the permitting and inspection processes for projects in jurisdictions that do not have their own certified local building departments. In areas where a city or county has a certified building department, that local jurisdiction acts as the Authority Having Jurisdiction (AHJ) for enforcing the state-adopted codes.
