Montana — How to Check a Contractor's License

Montana requires contractors to hold a state license for projects exceeding Registration required for businesses with employees in labor and materials. The Montana Department of Labor and Industry oversees licensing, complaints, and disciplinary actions.

Step 1: Get the Contractor's License Number

Any legitimate contractor in Montana should readily provide their license number. It should appear on their business card, vehicle, website, and advertising. If a contractor refuses to share their license number, don't hire them.

Step 2: Verify the License

Visit the Montana Department of Labor and Industry website to look up the contractor's license. We're working on adding Montana license data to our search tool — check our Montana page for updates.

When checking the license, verify:

• Status is "Active" — not expired, suspended, or revoked
• Name matches — the business name on the license should match who you're hiring
• Classifications cover your project — a plumbing license doesn't cover electrical work
• License won't expire during your project

Step 3: Check Bond and Insurance

While Montana does not require a surety bond for all contractors, you should still verify that your contractor carries general liability insurance and workers' compensation insurance (if they have employees). Ask for certificates of insurance before signing any contract.

Step 4: Check Complaint History

The Montana Department of Labor and Industry tracks complaints filed against licensed contractors. Before hiring, check if the contractor has any past disciplinary actions, complaints, or violations. Visit the Montana Department of Labor and Industry website to check complaint history.

What Happens if You Hire an Unlicensed Contractor?

Hiring an unlicensed contractor in Montana puts you at risk:

• Your homeowner's insurance may not cover work done by unlicensed contractors
• You have limited legal recourse if the work is defective
• No surety bond to file claims against
• Unpermitted work can cause problems when selling your home

How to Report an Unlicensed Contractor in Montana

If you suspect a contractor is working without a license in Montana, report them to the Montana Department of Labor and Industry. Unlicensed contracting is typically a misdemeanor and carries fines and potential jail time.
