Mechanical / HVAC Permit (State-Issued) in Colstrip, Montana

Because Colstrip holds no DLI certification in Mechanical (only a residential-only Building certification), mechanical/HVAC work anywhere within Colstrip city limits — residential or commercial — requires a Mechanical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Colstrip, under the 2021 International Mechanical Code and International Fuel Gas Code.

    Colstrip, Montana has adopted: Montana has a mandatory statewide building code administered by the Montana Department of Labor & Industry (DLI) Building Codes Bureau, amended by the Administrative Rules of Montana (ARM) Title 24, Chapter 301. Cities, counties, and towns may become 'certified' to locally administer permitting and inspection for all or part of the code; non-certified trades — and, where a city's Building certification is itself partial (e.g. residential-only), non-certified project types — fall under direct state administration by the DLI Building Codes Bureau.
