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.

As with Hardin and Anaconda-Deer Lodge, this residential-only certification does NOT cover commercial building work, meaning commercial building permits in Colstrip route to the state DLI Building Codes Bureau exactly as they would in a non-certified jurisdiction, in addition to Electrical/Plumbing/Mechanical for all project types.

The Montana Department of Labor & Industry Building Codes Bureau issues the electrical/interconnection permit for solar PV in Colstrip, using its statewide Application for Alternative Energy Permit — not the City, since Colstrip holds no DLI Electrical certification. The roof-mount/racking portion of a residential system may separately require a City of Colstrip Residential Building Permit.
