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.

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 verified directly 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.
