Zoning Permit in West Yellowstone, Montana

Yes — a Zoning Permit is required for erection of a fence within Town limits, per the Town's Application for Zoning Permit, in addition to any applicable Building Permit.

There is no single published day-count. After Development Review Group (DRG) approval, the Town Clerk schedules Planning Board review within 10 business days; the DRG itself meets only on the 1st and 3rd Thursday of each month, and the process continues to Town Council decision, so total timing depends on meeting cadence rather than a fixed calendar figure.

You'll need: Application for Zoning Permit; Detailed Site Plan. Depending on your project, West Yellowstone may also ask for: Commercial Site Plan Review Checklist. See the required-documents checklist on this page for details on each.

West Yellowstone, 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 (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.

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.pdf; The 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.pdf; West 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. Section 15.04.010(A) (fetched live via browser 2026-07-16 — codepublishing.com 403s to curl/plain fetch behind a Cloudflare challenge but renders normally in a browser) reads: 'The current editions of the building, mechanical and related codes and all accompanying appendices, amendments and modifications adopted by the Bureau of Building and Measurement Standards, Montana Department of Labor and Industry (or its successor)... shall be adopted by reference through administrative action of the operations manager, as authorized by Section 50-60-301(1)(b), MCA... These codes are applicable to all buildings within the building code enforcement area of the town, including, but not limited to, residential buildings containing less than five dwelling units...' This directly corroborates the Town's local Building (residential-only) certification deferring to state-adopted code editions, and resolves a prior review pass's 'honest access gap' note on this chapter — the text was reachable via a rendered browser fetch, not genuinely inaccessible.; 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.
