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 construction of new single-family homes, duplexes, and other residential structures in Kalispell. Reviewed against the 2021 International Residential Code (IRC) and 2021 Energy Code with Kalispell amendments. Applications are submitted through the city's online e-Permit portal.
From$23.50Commercial Building Permit (New Construction, Additions, Remodels, Tenant Improvements)
Required for new commercial construction, commercial additions, and commercial remodels or tenant improvements in Kalispell. The City of Kalispell is a Montana DLI-certified building code enforcement jurisdiction (certified scope B, P, M, E, SP, per the Montana Department of Labor & Industry Business Standards Division's Certified City, County and Town Programs list) and issues and inspects commercial permits itself within city limits, rather than referring them to the state Building Codes Bureau. Reviewed against the 2021 International Building Code as adopted at Kalispell Municipal Code Section 5-1A-4-2B, alongside the City's other 2021-cycle codes. Billed on the same valuation-based Commercial & Fire Systems Building Permit Fee Schedule used for fire alarm and sprinkler system plan review, with a Plan Review Fee of 65% of the Building Permit Fee, versus an hourly $75 plan review charge for residential work. Kalispell publishes no separate Tenant Improvement application or fee; the City's Certificate of Occupancy Procedure treats construction or tenant-improvement work tied to a change of use as going through this same Commercial Building Permit.
From$23.50Residential Addition / Remodel / Alteration Permit
Required for additions, remodels, decks, and structural alterations to existing residential structures in Kalispell. Uses the same valuation-based Building Permit Fee Schedule as new construction. Applications submitted through the online e-Permit portal.
From$23.50valuation-basedElectrical Permit
Required for electrical installations, service changes, and rewiring in Kalispell residential and commercial properties. Governed by the 2020 National Electrical Code (NEC). Kalispell is a Montana DLI-certified electrical code enforcement jurisdiction within city limits.
From$200.00Electric Vehicle (EV) Charger / EVSE Permit
Kalispell has no dedicated EV charger/EVSE fee line on its Electrical Permit Fee Schedule (effective 09/04/2024) or Electrical Permit Application form — EV charger (Level 2 or DC fast charging equipment) circuit installation is billed under the same itemized Electrical Permit fee categories used for other electrical work: the flat 'Interior Rewire or Addition' fee if the charger is added as a new circuit on existing service, or the amperage-tiered Residential/Accessory Service fees if the installation requires a new or upgraded electrical service. Kalispell is a Montana DLI-certified electrical code enforcement jurisdiction (certified scope includes Electrical) and issues/inspects the permit itself rather than referring it to the state.
From$120.00Plumbing Permit
Required for plumbing installations, alterations, and repairs in Kalispell, including water heater replacements and fixture additions. Governed by the 2021 Uniform Plumbing Code (UPC).
From$20.00Mechanical / HVAC Permit
Required for heating, cooling, ventilation, and fuel gas equipment installations in Kalispell. Governed by the 2021 International Mechanical Code (IMC) and 2021 International Fuel Gas Code (IFGC).
From$30.00Roofing Permit (Reroof)
Kalispell does not publish a distinct roofing-specific fee schedule or checklist; re-roofing and roof-structure work is permitted and fee-assessed under the standard Building Permit Fee Schedule based on project valuation, per the 2021 International Building Code and 2021 International Residential Code.
From$23.50valuation-basedSolar Photovoltaic (PV) Permit
Solar PV installations in Kalispell are permitted as electrical work under the standard Electrical Permit process — there is no separate 'solar permit' category. Commercial/solar installations are billed on the valuation-based electrical fee tier plus a $20 issuance fee.
From$45.00valuation-basedAccessory Dwelling Unit (ADU) Permit
Required for construction of a new accessory dwelling unit (or second unit as part of a duplex) on a residential property in Kalispell. Governed by Kalispell Municipal Code Section 27.20.082, substantially liberalized by Ordinance 1950 (effective May 4, 2026): an ADU is now a permitted use in any zone where a single-family dwelling is a permitted use.
From$23.50valuation-basedSign Permit
Required before displaying, erecting, relocating, or altering most signs in Kalispell, per Kalispell Municipal Code (KMC) 27.22.160, unless the sign is exempted under KMC 27.22.050. Permanent sign permits are billed using the City's currently adopted IBC (building valuation) Fee Schedule based on the declared value of the sign; most sign types (all except wall signs of any size) additionally require Architectural Review Committee (ARC) approval. Short-duration special-event signage (banners, portable reader boards, balloons/pennants) uses a separate flat-fee Temporary Sign Authorization.
See fee scheduleFire Sprinkler & Fire Alarm System Permit
Required for installation, modification, or repair of fire sprinkler (fire suppression) systems and fire alarm systems in Kalispell. Kalispell does not price or process fire alarm and fire sprinkler permits as a separate product — per the City's own published FAQ, a commercial building permit is required for the review of plans for fire alarm and sprinkler systems, billed on the Commercial & Fire Systems Building Permit Fee Schedule (the same valuation table used for other commercial building permits) plus a 65% plan review fee. Final sign-off is confirmed jointly by the Building/Fire division of the Building Department as part of the Certificate of Occupancy process.
From$23.50valuation-basedCertificate of Occupancy / Change of Use Permit
Kalispell issues a Certificate of Occupancy (CO) to authorize occupancy of a building once the Building Department and every other applicable city department (Building/Fire, Parks, Zoning, Public Works, and Fire) has inspected and approved the completed work. A change of use or structural expansion in an existing commercial, industrial, or multi-family structure separately triggers Major Site Plan Review under Kalispell Municipal Code Section 27.20 before a building permit or CO can be finalized. Kalispell does not publish a standalone 'change of use permit' fee or application distinct from this Major Site Plan Review + standard commercial building permit + CO sign-off sequence: neither the Building Fee Schedules page, the Planning Department Fee Schedule, nor KMC 27.20 carries a dedicated line item for it.

Tips & gotchas
- Kalispell is a Montana DLI-certified building code enforcement jurisdiction (certified scope: Building, Plumbing, Mechanical, Electrical, Swimming Pool/Spa — 'B, P, M, E, SP') within city limits only, per the state's Certified City, County and Town Programs list (MCA 50-60-302). Unincorporated Flathead County is enforced directly by the Montana Building Codes Bureau, not a county department.
- Kalispell's current adopted code cycle: 2021 IBC/IMC/IFGC/IFC, 2021 IEBC, 2021 IRC, 2021 Uniform Plumbing Code (UPC — not IPC), 2021 Energy Code, 2020 NEC, and 2021 ISPSC.
- Commercial plan review has a published lead time of 12-14 weeks from complete submittal; residential plan review is 2-3 weeks. Both figures are published on the Kalispell Building Department webpage.
- All permits are applied for through the online e-Permit portal at buildingpermits.ci.kalispell.mt.us; the Building Department also accepts emailed/faxed application PDFs for electrical, mechanical, and plumbing.
- Schedule inspections by emailing inspections@kalispell.com with your permit number/address, inspection type, and contact info; inspections must be scheduled 24-48 hours in advance and same-day inspections are not guaranteed.
- Work commenced without a required permit results in immediate stop-work and a 200% penalty fee on the original permit amount, per City of Kalispell Ordinance 1889 and Resolution 5703.
- Effective October 1, 2025, a 3% processing fee applies to credit card payments for permits; checks remain fee-free.
- Kalispell substantially liberalized its Accessory Dwelling Unit ordinance effective May 4, 2026 (Ordinance 1950) — ADUs up to 1,000 sq ft are now allowed in any zone permitting single-family homes, not just the previous limited set of zones.
- Solar PV has no dedicated permit category — it is processed as an Electrical Permit under the Commercial/Solar/Multi-Family valuation-based fee tier plus a $20 issuance fee.
- Plumbing permits use a simple flat structure ($20 base + $8/fixture or gas outlet) rather than a valuation table, unlike building, electrical, and mechanical permits.
