Processing time: Construction Contractor Registration and ICEC: typically a few weeks after a complete application is received by DLI. Electrical and plumbing license timelines depend on exam scheduling through the respective boards. from application submission to license issuance.

Montana (MT) does not license general contractors in the traditional sense. Instead, the Montana Department of Labor and Industry (DLI) operates a two-track registration system under the Workers' Compensation Act (MCA Title 39, Chapter 71): construction businesses with employees must obtain a Construction Contractor Registration, while self-employed contractors who want to opt out of workers' compensation must obtain an Independent Contractor Exemption Certificate (ICEC) after satisfying the statutory two-prong independent-contractor test under MCA 39-71-417 (control + independently established business). Montana does issue true state-level licenses for electricians (MCA Title 37, Ch. 68), plumbers (MCA Title 37, Ch. 69), and boiler operators, each administered by a dedicated board under DLI's Business Standards Division. There is no statewide bond requirement for general contractors — bond requirements, if any, are set by individual cities.

Step 1: Ask the Contractor Which Montana Credential They Hold

Montana does not license general contractors. For a contractor with employees, the correct credential is a Construction Contractor Registration (CCR). For a solo contractor opting out of workers' comp, it is an Independent Contractor Exemption Certificate (ICEC). For electrical, plumbing, or boiler work, a separate state license from DLI Business Standards is required. If a contractor cannot tell you which of these they hold, that is a red flag.

Step 2: Look Up Contractor Registration or ICEC

Use the DLI Employment Standards Division lookup at erdcontractors.mt.gov to verify a Construction Contractor Registration or Independent Contractor Exemption Certificate. You can search by business name or certificate number. The lookup shows the current status of the registration or exemption.

DLI Contractor / ICEC Search →

Step 3: Look Up Electrical, Plumbing, or Boiler Licenses

Electricians, plumbers, and boiler operators are licensed through the DLI Business Standards Division, not through the contractor registration program. Use the state's professional-licensing public search to verify these credentials.

Step 4: Verify Workers' Compensation Coverage

If the contractor has employees, Montana law requires workers' compensation insurance. You can confirm coverage through the state's workers' compensation coverage verification service.

Workers' Comp Coverage Verification →

Step 5: Check Local City Requirements

Because Montana does not have a statewide general contractor license, cities and counties set their own rules. Many Montana municipalities require a local contractor business license, permits, and in some cases a local bond. Call the building department for the city where the work will happen to confirm local requirements before signing a contract.

Montana Contractor Insurance Requirements

Insurance Type Requirement
Workers' Compensation Required for any construction contractor with employees under MCA Title 39, Ch. 71. Construction Contractor Registration exists specifically to verify that Montana workers' comp rates are being paid. A solo contractor can opt out only by obtaining an Independent Contractor Exemption Certificate (ICEC) — otherwise they are presumed to be an employee of whoever hires them.
General Liability Not required at the state level. Individual municipalities and project owners commonly require proof of general liability insurance.

Montana Contractor Bond Requirements

Montana does not impose a statewide surety bond on general contractors. Bond requirements, when they exist, come from individual cities and counties and vary by jurisdiction and project value.

Montana Consumer Protections for Home Improvement

Montana law provides several important protections for homeowners hiring contractors:

What Happens if You Hire an Unlicensed Contractor?

Hiring an unlicensed contractor in Montana puts you at risk:

How to Report an Unlicensed Contractor in Montana

Report unregistered contractors, misclassification of workers, or unlicensed electrical/plumbing/boiler work to the Montana Department of Labor and Industry. DLI investigates misclassification (ESD) and unlicensed trade work (Business Standards) on separate tracks.

How to File a Complaint Against a Registered Contractor in Montana

Complaints fall into two tracks in Montana. Misclassification and failure-to-register complaints go to DLI's Employment Standards Division. Complaints about licensed electricians, plumbers, or boiler operators go to DLI's Business Standards Division.

You can file a complaint by:

For contract disputes or financial recovery, Montana consumers typically pursue small-claims or district court; DLI does not mediate payment disputes.

Montana Contractor Bond Schedule

There is no state-level contractor license bond in Montana. Any bond requirement will come from a local building department, a project owner, or a general contractor subcontracting the work.

License Type Bond Amount Notes
Local Municipal Bond Varies by city Some Montana cities (such as Billings, Missoula, Bozeman) require a local contractor license and may require a bond. Check with the local building department.

What Makes Montana Contractor Licensing Unique

Registration, Not Licensing, for General Contractors

Montana is one of a small group of states that does not license general contractors at all. Instead, construction businesses with employees file a Construction Contractor Registration ($70) with DLI under MCA Title 39, Ch. 71. The registration confirms workers' compensation compliance — it is not a competency credential.

ICEC: The Montana Workaround for Solo Contractors

A solo contractor who wants to work without carrying workers' comp must obtain an Independent Contractor Exemption Certificate ($125) by satisfying the statutory two-prong independent-contractor test under MCA 39-71-417 (control + independently established business). Without an ICEC, Montana law presumes them to be an employee of whoever hires them — which can leave the hiring party on the hook for their workers' comp.

Electrical and Plumbing Are Fully Licensed

Even though general contractors only register, Montana does fully license electricians and plumbers under MCA Title 37, Ch. 68 and Ch. 69. The Montana State Electrical Board issues Master, Journeyman, Residential, and Contractor credentials. The Montana Board of Plumbers issues Master, Journeyman, and Medical Gas credentials. Both require exams.

Bonds Are a Local Matter

Montana imposes no statewide contractor bond. Any bond requirement comes from the city or county where work will happen. Always call the local building department before signing a contract.

Two Separate Lookup Systems

Contractor registrations and ICECs are searched at erdcontractors.mt.gov. Electrical, plumbing, and boiler licenses live in a completely different database on the state's Accela-hosted Professional Licensing portal (ebiz.mt.gov/POL, which redirects to aca-prod.accela.com/pol). Verifying a Montana contractor often requires checking both.

Frequently Asked Questions: Montana Contractor Licensing

Does Montana license general contractors?

No. Montana does not issue a general contractor license. Instead, construction businesses with employees must obtain a Construction Contractor Registration from the Department of Labor and Industry for $70, and self-employed contractors who want to opt out of workers' compensation must obtain an Independent Contractor Exemption Certificate for $125. The registration system is administered under MCA Title 39, Ch. 71 and focuses on workers' comp compliance rather than competency.

What is a Montana Independent Contractor Exemption Certificate (ICEC)?

An ICEC is a $125 certificate issued by the DLI Employment Standards Division that lets a self-employed contractor work without carrying workers' compensation insurance on themselves. To qualify, the applicant must satisfy the statutory two-prong independent-contractor test under MCA 39-71-417 (control + independently established business) — Montana uses an AB test, not the California-style ABC test. Without an ICEC, a solo contractor is presumed to be an employee of whoever hires them.

How do I look up a Montana contractor?

Use the DLI contractor and ICEC search at erdcontractors.mt.gov to verify a Construction Contractor Registration or Independent Contractor Exemption Certificate. For electricians, plumbers, and boiler operators, use the separate Professional Licensing portal at ebiz.mt.gov/POL (which redirects to aca-prod.accela.com/pol). Many Montana contractors need to appear in both systems.

Does Montana require electrical and plumbing licenses?

Yes. Even though Montana does not license general contractors, it does fully license electricians under MCA Title 37, Ch. 68 (Master, Journeyman, Residential, and Electrical Contractor) and plumbers under MCA Title 37, Ch. 69 (Master, Journeyman, and Medical Gas). Both require passing an exam, and electrical licenses require 16 hours of continuing education each renewal cycle per ARM 24.225.2102.

Does a Montana contractor need a surety bond?

Not at the state level. Montana does not impose a statewide contractor license bond. Bond requirements, when they apply, come from the city or county where the work is being done. Some Montana cities require a local contractor license and bond; call the local building department before signing a contract.

What happens if I hire an unregistered Montana contractor with employees?

A construction contractor with employees who has not filed a Construction Contractor Registration is likely not in compliance with Montana's workers' compensation requirements. If one of their workers is injured on your project and the contractor has no workers' comp, you could be exposed as the statutory employer. Always verify the registration at erdcontractors.mt.gov before hiring.

How do I file a complaint against a Montana contractor?

For failure to register, misclassification, or workers' comp issues, contact the DLI Employment Standards Division at (406) 444-6543 or (406) 444-7734, or dlierdiccr@mt.gov. For complaints against licensed electricians, plumbers, or boiler operators, contact DLI Business Standards at (406) 841-2319 or dlibsdcomplaints@mt.gov. For contract and payment disputes, Montana consumers generally use small-claims or district court.

How long does Montana contractor registration take?

A Construction Contractor Registration ($70) and an Independent Contractor Exemption Certificate ($125) are typically processed in a few weeks once DLI receives a complete application and supporting documents. Electrical and plumbing license timelines depend on exam scheduling and vary by license class.
