Montana

Montana separates general construction registration from trade-specific licensing. Any construction business must register with the Department of Labor and Industry and carry Montana workers’ compensation, but there is no exam, experience, or bond requirement for general registration. Electrical and plumbing work require separate state licenses with exams. Highway prequalification is narrow — it applies only to blasting, rockscape stabilization, and stream restoration.

Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.

Does Montana require a state contractor license for general construction?

Montana requires registration, not a traditional license, for general construction. Registration with DLI costs $70 for a two-year period and has no exam, experience, or bond requirement. You must carry Montana workers’ compensation coverage. See Requirements.

How do I get a plumbing or electrical license in Montana?

Electrical licenses are issued by the State Electrical Board. Journeyman electricians need 8,000 hours of practical experience and must pass an exam at 70%. Plumbing licenses are issued by the Board of Plumbers. Journeyman plumbers need 5 years of experience and must pass an exam at 70%. See Requirements and Who regulates construction.

What are Montana's workers' compensation registration requirements?

Montana must appear in section 3A (not 3C) of your workers’ compensation insurance declaration page. Workers’ comp is required when a contractor has employees. If you have no employees, you may need an Independent Contractor Exemption Certificate ($125 for two years). See Requirements.

Where do I go to register or get licensed in Montana?

General contractor registration goes through DLI’s Contractor Registration Unit. Electrical licensing goes through the State Electrical Board. Plumbing licensing goes through the Board of Plumbers. Highway work goes through MDT. See Who regulates construction.

How much does it cost to register and get licensed?

General registration is $70 for two years ($75 renewal). Electrical application by exam is $190 with $140 biennial renewal. Plumbing journeyman application is $270 with $160 annual renewal. Master plumber application is $380. See Requirements.

Can I use my out-of-state license in Montana?

Montana has workers’ comp extraterritorial agreements with 7 states (Idaho, ND, SD, OR, UT, WA, WY) covering insurance portability. The electrical and plumbing boards accept CE from reciprocal states, but specific partner states should be confirmed with each board. General registration has no reciprocity. See Reciprocal agreements.

Does Montana require a license for roofing work?

Roofing is covered under general construction registration. Register with DLI for $70 (two years) and carry Montana workers’ comp. No exam, bond, or experience is required for general construction registration. See Requirements.

What are the continuing education requirements?

Electricians must complete 8 hours of CE per year in the renewal cycle, with at least 4 hours on NEC updates. Plumbers must complete 4 hours annually. General contractor registration has no CE requirement. See Requirements.

Does Montana require prequalification for highway work?

Only for specialty work: blasting, rockscape stabilization, and stream restoration. General highway projects use standard MDT bidding without prequalification. Joint ventures must file a declaration and power of attorney with MDT before bidding. See Construction work regulated.

What does the out-of-state workers' comp agreement mean for contractors?

Montana’s extraterritorial agreements with 7 states allow workers’ comp coverage from those states to follow workers into Montana under certain conditions. These cover insurance portability, not credential recognition. You still must register with DLI and meet all other Montana requirements. See Reciprocal agreements.

How does Montana regulate general construction?

Montana uses a registration model, not a qualification-based license. Registration requires only a $70 fee and workers’ comp coverage — no exam, experience, or bond. This is one of the lightest entry points nationally. See Requirements.

What trades require state licensing in Montana?

Only two trades: electrical (through the State Electrical Board) and plumbing (through the Board of Plumbers). Both require exams, experience, and continuing education. All other construction trades are covered by the general registration model. See Construction work regulated.

How does the Montana DOT handle highway bidding?

MDT requires prequalification only for blasting, rockscape stabilization, and stream restoration. All other highway projects use standard bidding without prequalification. Joint ventures must file a declaration and power of attorney. See Construction work regulated.

How does Montana's registration model compare to licensing states?

Montana’s general construction registration has no exam, no experience requirement, and no bond — only a $70 fee and workers’ comp. This is dramatically lighter than states like Nevada (universal licensure with exams) or California ($1,000 threshold with exams and bonds). Trade licensing for electrical and plumbing does have real barriers.

What are the fees across registration and trade licensing?

Registration is $70 for two years. Electrical application is $190 with $140 biennial renewal. Electrical contractor is $210 with $210 biennial renewal. Plumbing journeyman is $270 with $160 annual renewal. Master plumber is $380 with $265 annual renewal. See Requirements.

What license classifications does Montana use?

Three regulatory families: Construction (registration, ICE certificate, home inspector), Electrical (master, journeyman, residential, limited/unlimited contractor), and Plumbing (journeyman, master, medical gas endorsement). See Types of licenses.

How does reciprocity work in Montana?

Workers’ comp extraterritorial agreements exist with 7 states (Idaho, ND, SD, OR, UT, WA, WY) covering insurance portability. Electrical and plumbing boards accept CE from reciprocal states. General registration has no reciprocity. See Reciprocal agreements.

What exam requirements exist?

General registration: no exam. Electrical journeyman/residential: 70% minimum. Electrical master: 75% minimum. Plumbing: 70% minimum. After repeated failures, additional CE is required before re-examination. See Requirements.

What are the renewal cycles?

Registration is biennial. Electrical individual licenses are biennial (May 15 through July 15). Electrical contractor licenses are biennial. Plumbing licenses are annual (July 1 through September 1). See Requirements.

How does Montana compare to neighboring Western states?

Montana is among the least regulated for general construction. Its $70 registration with no exam or bond is lighter than Idaho (registration plus trade licensing), Wyoming (electrical-only at state level), or Oregon (comprehensive endorsement system). See Licensing thresholds.

Special considerations

Different roles need different things from a Montana page. Use the tab that matches your situation to see what matters most before you read the full detail below.

Contractors
Regulators

Start with the type of work. General construction registration is fast and cheap, but electrical and plumbing require full licensing with exams.

Registration is required for all construction work — $70 for a two-year period.
No exam, experience, or bond is required for general contractor registration.
Workers’ comp insurance must list MT in section 3A, not 3C.
Electrical work requires a separate license from the State Electrical Board.
Plumbing work requires a separate license from the Board of Plumbers.
Highway specialty work (blasting, rockscape, stream restoration) requires MDT prequalification.

Readiness checklist

Four things you need to confirm before you can treat Montana as “ready” for a bid or an application. If any of these are unclear, you are not ready yet.

Classify the project lane

Identify whether the work is general construction, electrical, plumbing, home inspection, or highway specialty.

All construction work requires DLI registration ($70 for two years) and Montana workers’ comp coverage with MT in section 3A.

Route to the trade board

If the work involves electrical or plumbing, apply separately to the State Electrical Board or Board of Plumbers. General construction stops at DLI registration.

Confirm the requirement set

Confirm exams, experience, fees, continuing education, and renewal timing for the specific trade board before filing.

If you can identify lane, registration status, trade board (if applicable), and requirement set, you have the minimum package needed for a Montana readiness check.

Construction work regulated

Montana does not set a minimum contract value for general construction. Instead, it requires registration and workers’ comp coverage for all construction businesses regardless of project size. Electrical and plumbing are licensed separately.

Work lane	What triggers regulation
General construction	Registration and workers’ comp required — no dollar threshold
Electrical work	State license required for all electrical work
Plumbing work	State license required for all plumbing work
Home inspection	Registration required since January 1, 2020
Highway specialty	MDT prequalification for blasting, rockscape stabilization, and stream restoration

Montana does not require prequalification for general highway projects. Only blasting, rockscape stabilization, and stream restoration contractors need MDT prequalification. Joint ventures must file a declaration of joint venture and power of attorney with MDT before bidding on any highway contracts.

Common determination scenarios

If you are trying to figure out where to start, expand the scenario that is closest to your situation.

General construction — no trade work

Register with DLI for $70 (two-year period), carry Montana workers’ comp, and register with the Secretary of State. No exam, bond, or experience is required for general construction.

Electrical work on a project

The electrician must hold a state license from the Electrical Board. The employing contractor must identify a full-time Montana licensed journeyman or master electrician responsible for all work done in the state. The general contractor on the project must separately register with DLI.

Plumbing work on a project

The plumber must hold a state license from the Board of Plumbers. Journeyman plumbers need five years of experience; master plumbers need four additional years at the journeyman level. The general contractor must also register with DLI.

State highway specialty

Only blasting, rockscape stabilization, and stream restoration require MDT prequalification. General highway projects use standard MDT bidding without prequalification.

Out-of-state contractor entering Montana

Register with DLI, obtain Montana workers’ comp (check extraterritorial agreements with Idaho, ND, SD, OR, UT, WA, WY), and register with the Secretary of State. If doing electrical or plumbing work, apply separately to the relevant trade board.

Who regulates construction

Montana divides construction oversight across four agencies. DLI handles general contractor registration, while separate boards license electrical and plumbing trades. MDT handles highway work.

Reciprocal agreements

Montana does not operate a traditional state-to-state license reciprocity program for general construction. Workers’ comp extraterritorial agreements allow certain out-of-state coverage to follow workers into Montana. The electrical and plumbing boards accept CE from states with reciprocity, but the specific partner states are not published in general reference sources — confirm with each board directly.

Workers’ comp extraterritorial agreements are not the same as license reciprocity. They cover insurance portability, not credential recognition.

Agreement type	States	Coverage
Workers’ comp extraterritorial	Idaho, North Dakota, South Dakota, Oregon, Utah, Washington, Wyoming	7 states
Electrical Board	Confirm with Board — CE from reciprocal states accepted	Board-specific
Board of Plumbers	Confirm with Board — CE from reciprocal states accepted	Board-specific

Workers' comp extraterritorial agreement details

Montana’s extraterritorial workers’ compensation agreements allow coverage from Idaho, North Dakota, South Dakota, Oregon, Utah, Washington, and Wyoming to follow workers into Montana under certain conditions. These agreements cover insurance portability, not credential recognition. Contact Peter VanNice at (406) 444-0566 or PVanNice@mt.gov for details.
