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 / Addition / Remodel / Repair)
Required for new single-family residential construction, additions, remodels, repairs, and demolition within Columbia Falls city limits. Issued by the City of Columbia Falls Building Department under its DLI-certified local Building program (2021 IBC/IRC editions, Administrative Order 2022 Building Code Adoption). Application process begins at City Hall with the Building Clerk; inspections are performed under contract by the City of Whitefish Building Department.
Residential Addition / Remodel / Repair Permit
Required for additions, remodels, and repairs to existing residential structures within Columbia Falls city limits, processed through the same general Building Permit Application used for new construction (Class of Work: Addition, Remodel, or Repair). Reviewed against the 2021 IRC as adopted per Administrative Order 2022 Building Code Adoption.
Electrical Permit
Required for electrical installation, alteration, or repair work within Columbia Falls city limits, governed by the 2020 NEC. Columbia Falls is a Montana DLI-certified jurisdiction for electrical permitting, so this permit is issued and inspected locally (unlike non-certified Montana jurisdictions such as Havre, where it is issued by the state).
Plumbing Permit
Required for plumbing installation, alteration, or repair work within Columbia Falls city limits, governed by the 2021 Uniform Plumbing Code (UPC). Columbia Falls is a Montana DLI-certified jurisdiction for plumbing permitting, so this permit is issued and inspected locally.
Mechanical / HVAC Permit
Required for heating, ventilation, air conditioning, and related mechanical installations within Columbia Falls city limits, governed by the 2021 International Mechanical Code (IMC). Columbia Falls is a Montana DLI-certified jurisdiction for mechanical permitting, so this permit is issued and inspected locally.
Re-Roofing Permit
Re-roofing within Columbia Falls city limits is processed through the standard Building Permit Application (Class of Work: Repair), since no separate roofing-specific application, checklist, or fee schedule is published by the City. Governed by the 2021 IRC/IBC roofing provisions as adopted per Administrative Order 2022 Building Code Adoption.
Solar Photovoltaic (PV) Permit
Solar PV installations within Columbia Falls city limits require both a standard Building Permit (for the structural/roof- or ground-mounting component) and a standard Electrical Permit (for the electrical interconnection); no dedicated solar-specific application, checklist, or fee line is published by the City.
Demolition Permit
Demolition of a structure within Columbia Falls city limits is processed through the standard Building Permit Application, which explicitly lists Demolition as a Class of Work option. No separate demolition-specific application, checklist, or bond requirement is published by the City.
Fence and Retaining Wall Permit
Fences in Columbia Falls are regulated by zoning-district height limits under Title 18 (Zoning Regulations) rather than a dedicated fence-permit application; retaining walls over 36 inches in height are regulated as an accessory structure and require a building permit under Title 18, Chapter 18.436.

Tips & gotchas
- Columbia Falls is one of only three Montana cities (with Whitefish and Bozeman) holding the fullest DLI local-government certification tier: Building, Plumbing, Electrical, Mechanical, Swimming Pool, AND Wildland-Urban Interface (WUI). Certified official of record: Tad Lisowski. Source: Montana DLI Building Codes Bureau certified-jurisdictions PDF (bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdf), updated 04/22/2026.
- Despite issuing all permits itself, Columbia Falls does NOT perform its own building inspections — these are contracted out to the City of Whitefish Building Department. Schedule all inspections directly with Whitefish at (406) 863-2410 or buildingdept@cityofwhitefish.gov, minimum 24 hours' notice, project address required.
- The City of Columbia Falls has adopted all 2021 building-related codes (2021 IBC/IRC/IEBC/IMC/IFGC/IECC/ISPSC, 2020 NEC, 2021 UPC) per 'Administrative Order 2022 Building Code Adoption.'
- Design criteria printed directly on the Building Permit Packet: 55 lb minimum roof snow load, Seismic Zone D1, 115 MPH wind design.
- No standalone fee-schedule document exists separate from the permit application forms themselves — Building, Electrical, Mechanical, and Plumbing Permit Applications each print their own itemized/valuation-based fee tables directly on the form, and the Building Permit Fee, Plan Review Fee, and Fire Prevention Program Fee fields are filled in by the Building Department at time of submission rather than published as a standalone table.
- Absent a separately published Columbia Falls building-permit valuation table, the governing methodology is Montana ARM 24.301.138 (Calculation of Fees) / IBC Table 109.2, which sets $23.50 for the $1-$500 valuation tier and a 35% plan-review-fee surcharge — the same statewide formula that the neighboring DLI-certified City of Havre has published in full.
- Building-permit review timeline is set by Montana statute, not a city SLA: MCA 50-60-106(2)(c) requires Columbia Falls (a jurisdiction certified under 50-60-302) to issue a building permit or a notice of plan disapproval within 10 working days of a contractor's submission that includes the department's completed single-family-dwelling checklist. This 10-working-day statutory maximum governs every building-permit-pathway type here (new residential, additions/remodels, re-roofing, demolition, the solar mounting component, and retaining walls over 36 inches). It does NOT extend to standalone electrical, plumbing, or mechanical permits — those have no published city SLA and no statutory or ARM processing-timeline (the trade ARM rules set only 18-month validity), and Whitefish (which performs the reviews) publishes none either, so their reviewTimelineDays are genuinely null/hard-unpublished with the department contact given.
- No dedicated Accessory Dwelling Unit (ADU) permit, application, or zoning provision was found in Title 18 as currently in force, nor on the Permits & Applications or Forms & Permits pages.
- No dedicated solar photovoltaic permit, application, or fee line was found; solar installations use the general Building Permit (mounting) and Electrical Permit (interconnection) applications, with no solar-specific fee category on either form.
- No dedicated roofing-permit application, demolition-permit application/bond, or fence-permit application was found; roofing, demolition, and (where height triggers a permit) retaining walls are all processed through the single general Building Permit Application by selecting the applicable Class of Work.
- Retaining walls 36 inches (3 feet) or less above original grade require no permit at all; walls over 36 inches require a building permit and are capped at 4 feet above pre-existing grade, per Title 18, Chapter 18.436.
- Fence height limits are set per zoning district under Title 18, Chapter 18.424 and the individual zoning-district chapters — verify the specific limit for a property's district with the Planning Department rather than assuming a single citywide number.
