How to Verify a Contractor License Before You Hire

Before you sign a contract or pay a deposit for any construction, remodeling, or trade work, verify the contractor's license. It is free, it takes about two minutes, and it protects you from one of the most common and expensive home-services mistakes: hiring someone who is not actually licensed to do the work.

Why it matters

In most states, contractors performing work above a dollar threshold must hold a state license. Hiring an unlicensed contractor can mean no bonding, no insurance, no recourse through the licensing board, and in some states an unenforceable contract. A valid license also signals that the contractor has met experience, exam, and insurance requirements.

Step 1: Find the right licensing board

Contractor licensing is handled at the state level, and sometimes the city or county level too. Each state has its own board — for example, California's Contractors State License Board (CSLB). Use the Searchadex contractor license lookup to find the official board for the contractor's state, including high-demand markets like California, Texas, and Florida.

Step 2: Search by license number, name, or business

On the official portal, search by the license number the contractor gave you, or by their name or business name. Confirm the record matches the person and company you are actually dealing with — scammers sometimes borrow a real license number that belongs to someone else.

Step 3: Confirm the license is active and in good standing

Check the status field carefully. A license can be "current" but under disciplinary suspension. You want to see an active, unexpired license with no open disciplinary actions. Note the expiration date and the license classification — the class determines what type of work the contractor is legally allowed to perform.

Step 4: Check bond and insurance

Many state portals also show whether the contractor carries a required bond and workers' compensation insurance. Working with an uninsured contractor can leave you liable for on-site injuries. Confirm these are in place before work begins.

Step 5: Review disciplinary history

Public license records typically list citations, complaints, and disciplinary actions. A clean record is ideal; a single old resolved issue may be acceptable; a pattern of complaints is a reason to walk away.

Red flags to watch for

Be cautious if the contractor refuses to provide a license number, pressures you to pay entirely in cash up front, gives a license number that does not match their name, or holds a license in the wrong classification for your project. Each of these is a reason to pause.

For contractors: staying compliant

If you are a contractor yourself, keeping your license, registered agent, and business filings current across the states you work in is its own job. Harbor Compliance helps contractors manage licensing and compliance so a lapsed filing never costs you a job. Get a free compliance quote.
