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 (building, plumbing, electrical, mechanical, swimming pool, etc.); non-certified areas/trades — and, where a town'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 list (bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdf), directly fetched and text-extracted (PDF, updated 04/22/2026).West Yellowstone is a Montana DLI-certified jurisdiction for Building (B), RESIDENTIAL ONLY, within town limits — verified directly against the DLI Building Codes Bureau's official 'Montana Certified Local Government Program' roster (PDF, updated 04/22/2026, fetched and text-extracted directly via curl with browser headers after an initial normal-fetch MIME-type rejection): 'West Yellowstone | B (residential only) | Kyle Tanner | 602-4897 | City Limits'. This is the SAME narrower certification pattern as Hardin, MT and Deer Lodge County/Anaconda-Deer Lodge (B, residential only) — NOT the full-trade-set pattern of Manhattan (B, M, P, E, SP). Note: the Town's own Public Services webpage names its Building Inspector/Deputy Superintendent as 'KC Tanner' (ktanner@westyellowstone.gov, (406) 646-7609/640-9074) — this is presumed to be the same individual as the DLI roster's 'Kyle Tanner' (matching surname and role), but the given-name discrepancy (Kyle vs. KC) is reported honestly rather than silently reconciled, since it was not independently confirmed beyond the two source documents.COMMERCIAL building permits within West Yellowstone town limits are NOT covered by the Town's residential-only certification and are issued DIRECTLY by the Montana DLI Building Codes Bureau, exactly as in a non-certified jurisdiction. Electrical, Plumbing, and Mechanical/HVAC work — for BOTH residential AND commercial project types — likewise route DIRECTLY to the state DLI Building Codes Bureau, since West Yellowstone holds no certification in those trades at all. Source: Montana DLI Building Codes Bureau certified-jurisdictions roster PDF (updated 04/22/2026, directly fetched and text-extracted).The Town of West Yellowstone's own Zoning Permit Process (Commercial) document states explicitly: 'These permits are obtained through the State of Montana Department of Labor and are subject to separate fee schedules. Applicants must provide proof of state building permit and obtain a Town of West Yellowstone Business License.' This independently corroborates the DLI roster's residential-only/state-routed-commercial finding directly from the Town's own published materials. Source: Town of West Yellowstone, Zoning Permit Process-Commercial (PDF), https://www.townofwestyellowstone.com/wp-content/uploads/2026/05/Commercial-Zoning-Permit-fillable.pdfThe Town's own downloadable Building Permit form ('Building-Permit-FINAL.pdf') is a Town-branded local form, not a reformatted state BCP-1 template (contrast with Hardin), and states on its face: 'Separate permits are required for Electrical, Plumbing, Heating, Ventilating or Air Conditioning' and 'This permit becomes null and void if work or construction authorized is not commenced within 180 days, or if work is suspended or abandoned for a period of 180 days at any time after work is commenced.' Source: Town of West Yellowstone Building Permit (PDF), https://www.townofwestyellowstone.com/wp-content/uploads/2026/05/Building-Permit-FINAL.pdfWest Yellowstone Municipal Code (WYMC) Title 15, Buildings and Construction, contains Chapter 15.04 'Uniform Codes Adopted' and Chapter 15.08 'Moving Buildings.' The Town's own Application for Mechanical Permit form cites 'Section 15.04.010 WYMC and Section 8.70.105 ARM' as its authority. Direct text of WYMC 15.04 could not be retrieved: the live codepublishing.com site is Cloudflare-gated (returns a JS challenge page to both normal fetch and browser-header curl), and no Wayback Machine snapshot of the WestYellowstone1504.html page exists in the CDX index (confirmed by direct CDX API query) — only the Title 15 table-of-contents page (2015 snapshot, confirming the chapter titles above) and Chapter 15.08 (2020 snapshot, full text on moving buildings, unrelated to code adoption) were archived. This is reported as an honest access gap after exhausting live fetch, curl-with-browser-headers, and Wayback avenues, not omitted silently.The Town's own Application for Mechanical Permit form (citing WYMC 15.04.010) is a LOCAL Town-branded form with its own printed local fee schedule and 'Building Department, 646-7609' contact — this appears to be a legacy/superseded local mechanical-permit form predating, or inconsistent with, the DLI roster's current listing of West Yellowstone as certified for Building (residential only) ONLY with no Mechanical certification. Because the current, authoritative, dated (04/22/2026) DLI certified-jurisdiction roster is the governing source of truth for this project and does not list West Yellowstone as certified for Mechanical, this dataset treats Mechanical permitting in West Yellowstone as STATE-issued (per the DLI roster), while flagging the Town's own still-published Mechanical Permit form as a discrepancy worth confirming directly with the Town Building Department, (406) 646-7609, before relying on it. Omission of this discrepancy would violate the grounded-data policy, so it is disclosed rather than silently resolved in either direction.Statewide adopted codes (Administrative Rules of Montana, Title 24, Chapter 301), applicable both to West Yellowstone's locally-certified residential Building program and to the state-enforced trades and commercial building work: 2021 International Building Code (IBC), 2021 International Residential Code (IRC), 2021 International Existing Building Code (IEBC), 2021 International Mechanical Code (IMC), 2021 International Fuel Gas Code (IFGC), 2020 National Electrical Code (NEC), 2021 Uniform Plumbing Code (UPC), 2021 International Energy Conservation Code (IECC), 2021 International Swimming Pool and Spa Code (ISPSC), ICC A117.1-2017 Accessibility — all effective June 11, 2022.

Commercial Building Permit (State-Issued)

Verified

Because West Yellowstone's DLI certification for Building covers RESIDENTIAL work only, any commercial building project within town 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 Town, under the 2021 IBC. The Town's own Commercial Zoning Permit process explicitly requires proof of this state building permit before issuing its local Zoning Permit and Business License.

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
Building permits must be issued before related Plumbing, Mechanical, or Electrical permits can be issued or that work can begin
Applicant must provide proof of the issued state building permit to the Town of West Yellowstone as part of the Town's Commercial Zoning Permit / Business License process

Electrical Permit (State-Issued)

Verified

Because West Yellowstone holds no DLI certification in Electrical (only a residential-only Building certification), electrical work anywhere within town limits — residential or commercial — requires a Residential, Homeowner, or Commercial Electrical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the Town, under the 2020 NEC. The same statewide BCP-1 fee schedule already documented for Anaconda-Deer Lodge and Hardin applies.

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

Verified

Because West Yellowstone holds no DLI certification in Plumbing (only a residential-only Building certification), plumbing work anywhere within town 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 Town, under the 2021 Uniform Plumbing Code. The same statewide BCP-1 fee schedule already documented for Anaconda-Deer Lodge and Hardin applies.

Application must be signed by the Master Plumber and include the Master Plumber License Number, or filed as a homeowner permit for owner-performed work where allowed
Homeowner exemption: a homeowner does not need a state plumbing permit if performing the installation themselves on their own owner-occupied residence, not built for resale or as a rental
Property address, county, and whether the job is inside city limits must be indicated

Mechanical / HVAC Permit (State-Issued)

Verified

Because West Yellowstone's current DLI certification covers Building (residential only) and does NOT include Mechanical, mechanical/HVAC work anywhere within town limits — residential or commercial — is treated in this dataset as requiring a Mechanical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, under the 2021 International Mechanical Code and International Fuel Gas Code, using the same statewide BCP-1 fee schedule already documented for Anaconda-Deer Lodge and Hardin. NOTE: the Town of West Yellowstone also still publishes its own local 'Application for Mechanical Permit' form (citing WYMC 15.04.010) with a distinct local fee schedule and 'Building Department, 646-7609' contact — this appears inconsistent with the current DLI roster and should be confirmed directly with the Town before relying on either fee schedule.
