Do you need a general contractor license in Montana?

Yes, a license. In Montana, an individual or business may not engage in business as a construction contractor, including altering, repairing or improving buildings and installing roofing or siding for others, without a current license from the Department of Labor and Industry. The chapter does not apply to a job whose aggregate contract price is less than $2,500, to an independent contractor with no employees (who may register voluntarily), to licensed electricians or plumbers working within their license, or to an owner working on the owner’s own property, among other exemptions. The license requirement was enacted in 2025 (Ch. 644) and replaced the former registration under Title 39, chapter 9. Cities and counties can add their own licensing on top of the state’s. This is Mont. Code Ann. §§ 37-45-201, 37-45-102, 37-45-104.
