Garage door rules in Fergus County, Montana

Montana Department of Labor & Industry, Employment Standards Division - Montana Construction Contractor License (CCL) Program — official site

A licence, as of 2026. "Effective January 1, 2026 - All construction contractors in the state of Montana are required to be licensed with the Montana Department of Labor & Industry." Montana House Bill 239 (2025 session) "transitioned the state's construction contractor system from a basic registration framework to an official licensing program." Contractors that held an active Montana registration as of December 31, 2025 were converted to the new licence. A "construction contractor" means a person, firm or corporation that "in the pursuit of an independent business, offers to undertake, undertakes, or submits a bid to construct, alter, repair, add to, subtract from, improve, move, wreck, or demolish for another a building, highway, road, railroad, excavation, or other structure, project, development, or improvement attached to real estate" - which covers garage door installation and repair. Application fee $70.00 (non-refundable), renewal fee $70.00, no continuing education required. Anyone treating Montana as a registration-only state is working from pre-2026 information.

$2,500. Mont. Code Ann. 37-45-104 (Exemptions), subsection (8), exempts "work or operation on one undertaking or project considered of a casual, minor, or inconsequential nature, by one or more contracts, the aggregate contract price of which, for labor and materials and all other items, is less than $2,500 a job." The exemption does not apply where the work is part of a larger operation or where contracts are split into sub-$2,500 amounts to evade the chapter.

Montana has adopted the International Building Code, 2021 Edition and the International Residential Code, 2021 Edition, both effective June 11, 2022 (ARM Title 24, Chapter 301) - see https://bsd.dli.mt.gov/building-codes-permits/current-codes. Outside certified cities, all state-owned agency buildings must be permitted, while these are exempt from a state building permit: farm and ranch buildings; mining buildings on mining property; petroleum refineries and pulp and paper mills (except office and shop buildings); "residential buildings containing less than five dwelling units (except when serving transient guests)"; and "private garages and private storage buildings used for the owner's own use (not part of a commercial enterprise or business)." So a typical detached/attached private garage door job usually falls outside the STATE permit; certified cities and counties may still require a local permit.
