Codes adopted
Montana adopts a single statewide building code by rule and, by default, enforces it directly — local governments only gain enforcement authority once the state certifies them. Under the Montana Building Codes Act (Mont. Code Ann. Title 50, Chapter 60), the Department of Labor & Industry's Building Codes Bureau adopts one state building code applicable everywhere (§ 50-60-203, codified further at Administrative Rules of Montana Title 24, Chapter 301) — currently the 2021 editions of the IBC, IRC, IMC, IFGC, IECC, IEBC, ISPSC, and UPC, with the 2020 NEC for electrical (effective statewide since 6/11/2022 per the Bureau's own Current Codes page). A city, county, or town may adopt and enforce its own building-code program under § 50-60-301, but its adopted code "may include only codes adopted by the Building Codes Bureau" — a local edition can never diverge from or be less stringent than the state's. Critically, under § 50-60-302, a local government cannot enforce ANY building code — even one it has formally adopted — until the Bureau certifies its program (requiring an approved code, a published fee schedule, an enforcement plan, and properly licensed or nationally certified inspectors); certification is granted per TRADE, not as one blanket designation. The Bureau's own "Certified City, County and Town Programs" list uses the key B=Building, P=Plumbing, E=Electrical, M=Mechanical, SP=Pool, W=Wildland-Urban-Interface — a jurisdiction can be certified for Building only while Electrical/Plumbing/Mechanical remain directly state-enforced within the same city limits (e.g., Havre, Anaconda-Deer Lodge), or certified across all trades (e.g., Billings, Missoula, Great Falls, Bozeman, Helena, Kalispell). Non-certified jurisdictions — most of Montana's unincorporated county land, since very few counties appear on the certified list — fall under direct enforcement by the state Building Codes Bureau (§ 50-60-304). Montana also exempts private homes and buildings of four or fewer dwelling units not serving transient guests from the state building-permit requirement entirely, though electrical, plumbing, and mechanical permits remain separately required regardless. Always confirm with the specific jurisdiction which trades it is certified for versus which remain directly state-enforced.
Permit types & fees
Residential Building Permit (New Construction)
Required for new single-family and two-family dwelling construction within Laurel city limits. Reviewed against the 2021 IRC (Laurel City Code Chapter 14.16) and 2021 IECC (Chapter 14.22) as locally adopted by the City of Laurel. Laurel is a Montana DLI-certified Building (B) jurisdiction; applications are submitted on the city's universal Construction Permit and Application form at City Hall.
Residential Addition / Remodel / Alteration Permit
Required for additions, remodels, decks, and structural alterations to existing one- and two-family dwellings within Laurel city limits, reviewed against the 2021 IRC and 2021 IEBC (Laurel City Code Chapter 14.18) as locally adopted. Applied for on the same universal Construction Permit and Application form as new construction.
Residential Electrical Permit (State-Issued)
Required for electrical installation, alteration, or repair anywhere within Laurel city limits. Because Laurel is NOT DLI-certified for Electrical, this permit is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena) — not the City of Laurel — under the 2020 National Electrical Code (NEC). Laurel's own Building Department page directs applicants to the state for this permit.
Residential Plumbing Permit (State-Issued, including Water Heater)
Required for plumbing work anywhere within Laurel city limits, including new water heater installation/replacement. Because Laurel is NOT DLI-certified for Plumbing, this permit is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena) under the 2021 Uniform Plumbing Code, not the city.
Residential Mechanical / HVAC Permit (State-Issued)
Required for mechanical/HVAC work anywhere within Laurel city limits, including furnaces, gas piping, ventilation, and cooling equipment. Because Laurel is NOT DLI-certified for Mechanical, this permit is issued directly by the Montana Department of Labor & Industry Building Codes Bureau (Helena) under the 2021 International Mechanical Code, not the city.
Roofing Permit (Residential / Commercial)
Required for re-roofing within Laurel city limits, whether residential or commercial. Laurel's own Building Department page lists roofing (commercial and residential) explicitly among the permit types it handles directly under its Montana DLI Building (B) certification. Reviewed against the 2021 IRC/IBC as locally adopted (Laurel City Code Chapters 14.12/14.16).
Demolition Permit (Residential / Commercial)
Required for demolition of any structure within Laurel city limits. Laurel's own Building Department page lists demolition permits explicitly among the permit types it handles directly under its Montana DLI Building (B) certification. Residential demolition is a flat fee; commercial demolition is valuation-based per the Appendix A table.
Fence Permit
Required for fence installation within Laurel city limits. Laurel's own Building Department page lists fence installation explicitly among the permit types it handles directly. 'Fence' is defined at Laurel City Code 17.08.460 as 'a barrier of posts connected by boards, rails, panels or wire ... including masonry walls, ornamental structures, privacy screens and shrubs.'
Solar Photovoltaic (PV) Permit — Split City/State
Residential solar PV installations within Laurel city limits require two separate permits: a state-issued Residential Electrical Permit (Alternative Energy Source add-on) from the Montana DLI Building Codes Bureau for the electrical interconnection, since Laurel is not DLI-certified for Electrical, plus a City of Laurel Building Permit for the structural roof- or ground-mounting component, since Laurel IS DLI-certified for Building. No dedicated 'solar permit' line exists in either the city's or the state's fee schedule; each side uses its existing general-purpose permit and fee structure.

Tips & gotchas
- Laurel has a split enforcement model like Havre, but with a different certification tier: the city itself is DLI-certified for BUILDING and SWIMMING POOL only ('B, SP' designation) — Electrical, Plumbing, Mechanical, and Fuel/Gas permits within Laurel city limits are issued directly by the Montana Building Codes Bureau in Helena, not the city. Source: Montana DLI Building Codes Bureau, Certified City, County and Town Programs PDF (updated 04/22/2026), Laurel row: 'B, SP / Jason Gonzales / 628-4796 / City Limits'.
- Unincorporated Yellowstone County (outside both Laurel and Billings city limits) does not appear on the state's certified-jurisdictions list at all — every permit type there (Building, Electrical, Plumbing, Mechanical) is issued directly by the state Building Codes Bureau, mirroring the routing documented in billings.json.
- Laurel's own Code of Ordinances Title 14 contains adoption chapters ONLY for the codes it is certified to enforce — Chapter 14.12 (2021 IBC, Ord. O22-01), Chapter 14.16 (2021 IRC, Ord. O22-03), Chapter 14.18 (2021 IEBC), Chapter 14.22 (2021 IECC), and Chapter 14.23 (2021 ISPSC, Ord. O22-01) — with no local Electrical, Plumbing, Mechanical, or Fuel Gas chapter, corroborating the DLI certification list independently.
- Building permit fees, plan review fees, and Building Department line-item fees (fence, roof, demolition, deck, siding, window/door, mobile home blocking, etc.) are all set by the City Council's annual Schedule of Fees and Charges resolution under Laurel City Code 14.03.010 — the current version is Resolution No. R25-18 (effective March 11, 2025).
- Building Permit fees follow a valuation-based table (Resolution No. R25-18, Appendix A) starting at $36.00 for a $1-$500 valuation, scaling to $1,491.00 for the first $100,000 (plus $6.40/additional $1,000) at higher valuations. Residential Plan Review = 50% of the Building Permit Fee; Commercial Plan Review = 65%. The Building Permit Fee doubles if work starts before the permit is issued.
- The City of Laurel's own Building Department page explicitly lists which permits it handles directly (Building, Demolition, Right-of-Way, Fence, Roofing commercial/residential) versus which go to the state (Electrical, Fuel/Gas, Mechanical, Plumbing) — this is one of the clearest self-documented splits found among Montana jurisdictions researched to date.
- The City of Laurel publishes no plan-review turnaround of its own (confirmed across the Building Department page, Forms page, FAQs, Construction Permit application PDF, and the R25-18 fee schedule). Review timelines are instead the governing statutory/state-agency figures: city-issued single-family building permits are bound by MCA 50-60-106(2)(c)'s 10-working-day permit-or-disapproval deadline (Laurel is certified under 50-60-302; triggered when the state SFD checklist is attached), and state-issued electrical/plumbing/mechanical permits follow the Montana DLI Building Codes Bureau's published ~three-week average. Only the flat-fee, city-handled roofing, demolition, and fence permits remain genuinely unpublished — no permit-type-specific city timeline exists and the SFD-checklist statute and state Bureau turnaround do not reach them.
- No dedicated ADU permit type/fee, and no dedicated solar permit fee line, were found in Laurel's fee schedule — both follow the standard Building Permit / Electrical Permit frameworks rather than having bespoke city fee lines (see localAmendments for full reasoning).
- Fire protection plan review for Laurel is handled by a third-party contractor, FSCI (www.firesafetyfsci.com), not the city Building Department directly, per the City of Laurel Building page.
- The State's currently adopted codes (effective June 11, 2022, identical to the Billings/Havre entries) are: 2021 IBC, IRC, IECC, IEBC, IMC, IFGC, ISPSC; 2021 Uniform Plumbing Code; 2020 NEC; 2017 ICC A117.1 Accessibility.
