How to Verify a Contractor License in Montana

TL;DR — Verifying a Contractor License in Montana in 60 Seconds

Montana does not require a statewide general contractor license. However, electricians, plumbers, and elevator contractors must be licensed through the Montana Department of Labor & Industry (DLI). To verify a Montana trade professional, search by name or license number on LicensedCheck.com or through the DLI license lookup portal. Confirm the license is active, the license type matches the work you need (e.g., journey-worker electrician vs. supervising electrician), and check the expiration date. Montana has over 21,000 licensed electricians, plumbers, and elevator contractors in the state database.

Which Montana Trades Require State Licensing

Montana licenses several electrical and plumbing classifications through DLI. Electricians include journey-worker electrician, supervising electrician, residential electrician, maintenance electrician, industrial electrician, and specialty electrician — each with different scopes of allowed work and experience requirements. Plumbers include journey-worker plumber and master plumber. Elevator contractors and mechanics are licensed through the Elevator Operator Program.

General contractors are not licensed at the state level in Montana. Some municipalities including Billings, Missoula, and Bozeman may require local contractor registration or permits. Always check with your local building department for any additional requirements beyond state trade licensing.

Montana also requires building permits for most construction projects through local jurisdictions. Even though general contractors do not need a state license, they must still comply with local building codes and obtain appropriate permits.

Protecting Yourself When Hiring in Montana

For electrical and plumbing work, always verify the tradesperson holds the correct Montana license on LicensedCheck.com. Make sure a journey-worker or higher classification is performing or supervising the work — apprentices and helpers must work under licensed supervision.

For general contracting work where no state license is required, focus on insurance verification. Request proof of general liability insurance and workers compensation coverage. Montana law requires workers compensation for all employers, so any contractor with employees must carry it.

Get a written contract with scope of work, total cost, payment schedule, timeline, and any applicable license numbers. Watch for red flags: an electrician or plumber who cannot provide a license number, missing insurance documentation, demands for full payment before work begins, and reluctance to pull required building permits. Verify trade credentials on LicensedCheck first, then confirm local requirements with your city or county building department.
