What Are Montana's Contractor Licensing Rules?

Is a contractor license required in Montana?

Yes, but for general construction that's an administrative license rather than a competency exam. What used to be called Construction Contractor Registration became the Construction Contractor License (CCL) on January 1, 2026, under House Bill 239 — the name changed, but it's still not an exam-based license and doesn't require a qualifying individual. Electrical and plumbing are different: both are real statewide licenses, each with individual credentials and a genuine business-qualifying relationship. There's no statewide HVAC or mechanical contractor license — Montana only regulates electricians and plumbers at the state level among the specialty trades.

Which agency regulates it?

The Department of Labor & Industry's Business Standards Division houses three genuinely separate programs: the Construction Contractor License Program for general construction, the State Electrical Board for electricians and electrical contractors, and the Board of Plumbers for plumbers. They're independent regulatory bodies within the same division, not sub-committees of one combined trades board.

Where can you find the actual laws?

The Construction Contractor License is Montana Code Annotated Title 37, Chapter 45, with rules in Administrative Rules of Montana (ARM) 24.227. Electrical licensing is Title 37, Chapter 68 — individual licensing and qualifications are §§ 37-68-304 and 37-68-305, and electrical contractor licensing is § 37-68-312, with the business-qualifying mechanism detailed in ARM 24.141.505 and the definition of "responsible electrician" in ARM 24.141.301. Plumbing licensing is Title 37, Chapter 69 — the license requirement is § 37-69-301, master plumber qualifications and the license-use restriction are § 37-69-305, and the business-qualification mechanism is § 37-69-306. The Business Standards Division publishes all three programs' current licensing instructions directly.

What does it take to get licensed?

The Construction Contractor License requires a $70 fee, with no exam and no documented experience — just compliance with workers' compensation and unemployment insurance where applicable, and some no-employee independent contractors are exempt entirely. Electrical licensing requires real, documented experience: a journeyman typically completes an approved apprenticeship, 8,000 hours of practical experience, and 576 hours of related instruction before passing an exam at 70%, and a master needs four more years of journeyman experience before passing the master exam at 75%. A business then qualifies for either an Unlimited Electrical Contractor license, which requires a master electrician as its "responsible electrician," or a narrower Limited Electrical Contractor license, which only requires a journeyman and is capped at residential buildings under five dwelling units. Plumbing follows a similar two-tier structure: a journeyman generally completes an apprenticeship or qualifying experience and passes an exam at 70%, and a master needs four years as a journeyman — three of which have to involve working under a master plumber or in a supervisory role, which can overlap with the four — plus the master exam, also at 70%. A plumbing business satisfies its own master-plumber requirement when the license is held by someone who's either an owner ("principal") of the firm or simply an employee ("individual of the firm") — either relationship works.

What are the penalties for operating without a license?

Montana's general professional-licensing enforcement statute applies to unlicensed practice in any regulated trade unless another statute sets a different penalty: it's a misdemeanor, carrying a fine of $250 to $1,000, 90 days to a year in jail, or both, plus the state can seek an injunction against continued unlicensed practice. The Construction Contractor License program separately authorizes discipline for unprofessional conduct — fraud, misrepresentation, and similar violations — though the precise current penalty schedule under the renamed 2026 program isn't published as plainly as the general enforcement statute. There's no statewide consumer recovery fund tied to any of the three programs.

Does Montana have reciprocity with other states?

Real for both trades, though broader for electrical. Montana's published electrical reciprocity list covers around 16 states, including Alaska, Arkansas, Colorado, Idaho, Iowa, Maine, Minnesota, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, Wisconsin, and Wyoming — mainly for journeyman and residential-level credentials, and it doesn't automatically extend to the contractor business license. Ohio isn't on Montana's own list, even though Ohio's board lists Montana on its side — reciprocity here runs one direction at a time, the same pattern seen in several neighboring states. Plumbing reciprocity is narrower: Idaho, North Dakota, Oregon, and South Dakota, covering journeyman plumbers only, not masters — an applicant may still have to pass Montana's practical exam even with a qualifying out-of-state license.

Is it legal to rent or lease a license in Montana?

Electrical draws this line explicitly. The responsible electrician named on a contractor's license has to be engaged full-time, actually supervise the business's electrical work, and can only be named for one electrical contractor at a time — a master electrician can't qualify more than one Unlimited Electrical Contractor simultaneously, and the same goes for a journeyman and a Limited Electrical Contractor license. If that person leaves, both sides have to notify the board within 10 working days, and failing to name a replacement in that window is grounds for suspending the contractor's license. Plumbing's statute reads more restrictively on its face — it bars a master plumber from letting any business "other than the master plumber's own" use the license — but read together with the business- qualification provision, "the master plumber's own" just means whichever single firm the master is properly on record for, which can be established through real employment, not only ownership. The practical effect is the same one-business-at-a-time model as electrical: a master plumber can genuinely qualify an employer's business, but can't let a second, unrelated business piggyback on that same license. The Construction Contractor License has no qualifying role to rent out at all, since it's a simple administrative license with no individual credential attached to it.
