Codes 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. Source: Montana DLI Building Codes Bureau, Certified City, County and Town Programs (bsd.dli.mt.gov/building-codes-permits).Forsyth is a Montana DLI-certified jurisdiction for Building (B), RESIDENTIAL ONLY, within city limits; certified official on file with DLI: Gabe Martinsen, 406-346-2521. Verified directly against the DLI Building Codes Bureau's 'Montana Certified Local Government Program' roster PDF, updated 04/22/2026 (fetched and text-extracted directly from the source PDF): 'Forsyth | B (residential only) | Gabe Martinsen | 406-346-2521 | City Limits'. Note: Gabe Martinsen is ALSO the certified official listed for Miles City, MT (B, M, SP, E (residential only)) on the same roster — a single official serving two separate certified programs is plausible (shared regional building inspector) but was not independently confirmed beyond the roster entry itself. Source: https://bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdfColstrip, MT — also within Rosebud County — holds its OWN INDEPENDENT Montana DLI certification for Building (B), RESIDENTIAL ONLY, with a DIFFERENT certified official (Russell Murphy, 853-5084) and a different city-limits jurisdiction line on the same roster: 'Colstrip | B (residential only) | Russell Murphy | 853-5084 | City Limits'. This confirms Forsyth and Colstrip run INDEPENDENT city-level certified Building programs — they do NOT share a single county-level program, despite both being located in Rosebud County. Rosebud County itself does not appear on the DLI roster as a certified jurisdiction in its own right. Source: Montana DLI Building Codes Bureau, Certified Local Government Program roster PDF (updated 04/22/2026)Rosebud County's own Planning & Permitting department (County Planner page, rosebudcountymt.gov) explicitly states: 'Building and electrical permits are not required through Rosebud County, but may be required by the State of Montana.' The County Planner's office assists the City of Forsyth, City of Colstrip, unincorporated communities, and independent boards within Rosebud County with subdivision, flood plain, zoning, and septic permitting only — NOT building or electrical permitting, which is consistent with Forsyth and Colstrip each running their own independent city-level DLI-certified Building programs rather than a county-administered one.

Note the adopted code editions (2012 IBC/IMC/IFGC/UPC/IEBC, 2014 NEC, 2018 IRC/IECC) are OLDER than the state's current statewide-effective editions (2021 IBC/IRC/IEBC/IMC/IFGC/IECC/ISPSC/UPC, 2020 NEC per the DLI Building Codes Bureau's Current Codes page effective June 11, 2022) — Forsyth's local ordinance text has not been updated to match the state's most recent code-adoption cycle, though the state-enforced trades (Electrical, Plumbing, Mechanical) in Forsyth are governed by whatever edition the state DLI Building Codes Bureau currently applies statewide, not this local ordinance text.

Applicants must contact Forsyth City Hall at (406) 346-2521 for a current fee quote.

Commercial Building Permit (State-Issued)

Verified

Because Forsyth's DLI certification for Building covers RESIDENTIAL work only, any commercial building project within Forsyth city limits — new construction, addition, alteration — requires a Building Permit/Plan Review Application issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Forsyth.

Requirements

Submit a Building Permit/Plan Review Application together with complete construction plans to the Building Codes Bureau
Plan review fee is generally 1%-2% of building valuation, calculated by the Bureau after initial screening
A state building permit must be obtained before construction begins; starting construction beforehand may result in an investigation fee and required corrective construction
Building permits must be issued before related Plumbing, Mechanical, or Electrical permits can be issued or that work can begin

Electrical Permit (State-Issued)

Verified

Because Forsyth holds no DLI certification in Electrical (only a residential-only Building certification), electrical work anywhere within Forsyth city limits — residential or commercial — requires a Residential or Commercial Electrical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Forsyth, under the National Electrical Code as currently adopted statewide (2020 NEC per the Bureau's Current Codes page; Forsyth's own local ordinance text at 11-1-1 references the older 2014 NEC edition for its own — inapplicable to this state-enforced trade — reference).

Plumbing Permit (State-Issued, incl. Water Heater)

Verified

Because Forsyth holds no DLI certification in Plumbing (only a residential-only Building certification), plumbing work anywhere within Forsyth city limits — including water heater installation/replacement, residential or commercial — requires a Plumbing Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the City of Forsyth, under the Uniform Plumbing Code as currently adopted statewide (2021 UPC per the Bureau's Current Codes page; Forsyth's own local ordinance text at 11-1-1 references the older 2012 UPC edition for its own — inapplicable to this state-enforced trade — reference).

Mechanical / HVAC Permit (State-Issued)

Verified

Because Forsyth holds no DLI certification in Mechanical (only a residential-only Building certification), mechanical/HVAC work anywhere within Forsyth 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 Forsyth, under the International Mechanical Code and International Fuel Gas Code as currently adopted statewide (2021 IMC/IFGC per the Bureau's Current Codes page; Forsyth's own local ordinance text at 11-1-1 references the older 2012 editions for its own — inapplicable to this state-enforced trade — reference).
