How to check a contractor's license before hiring

Checking a contractor's license takes about ten minutes and costs nothing. Ask the contractor for their exact business name and license number, find your state's contractor licensing board online, and run the lookup. You are confirming four things: the license is active, it is held by the same business named on your contract, it covers the type of work you are hiring for, and there is no disciplinary history that worries you. Most states run a free public search for exactly this purpose. The ten minutes matter because everything downstream, permits, insurance, your recourse if things go wrong, rests on that license being real.

Here is how to do it properly, and what to watch for.

Why does the license actually matter?

A license is not a talent certificate. Plenty of skilled people work unlicensed, and a license alone does not guarantee good work. What the license buys you is accountability and infrastructure. Licensed contractors can pull permits in their own name. They answer to a state board that can hear complaints and impose discipline. In many states, licensing comes bundled with bonding requirements that give homeowners a path to compensation when something goes seriously wrong. None of that exists with an unlicensed operator, no matter how charming the estimate.

Unlicensed work also follows the house. Projects done without permits or by unlicensed hands can surface during a sale, in an insurance conversation, or in the next owner's inspection. You may save on the quote today and pay for it in paperwork years later.

How do you actually look up a license?

Start with the contractor. Ask for the business name exactly as it is licensed, and the license number. A legitimate contractor hands these over without hesitation, often before you ask. Hesitation here is information.

Then find the official source. Search for your state's name plus contractor license lookup, and make sure you land on a government site, typically the state contractor board, department of labor, or consumer affairs agency. Every state structures this differently, and a few leave licensing to cities or counties, so if the state search comes up empty, check your local jurisdiction before assuming anything.

On the lookup page, verify four fields. Status: the license should be active, not expired, suspended, or revoked. Name: the licensed entity should match the name on your estimate and contract, because a license held by a different company than the one you are paying protects you far less than it appears to. Classification: licenses are usually issued for specific trades or scopes, and a license in one trade does not authorize another, so confirm the classification fits your project. History: many boards show complaints, discipline, or bond claims, and a pattern is worth more attention than a single old entry.

What about insurance and bonding?

The license lookup is step one, not the whole job. Ask separately for proof of liability insurance and, if the contractor has employees, workers compensation coverage. Request the certificate of insurance be sent to you directly from the contractor's insurance agent, which confirms the policy is current rather than a photocopy of an old one. If a worker is hurt on your property and the contractor carries no coverage, the situation can land uncomfortably close to your own homeowners policy.

Bonding, where your state requires it, is a form of financial guarantee tied to the license. The board lookup often shows whether the bond is in place. You do not need to become an expert in any of this. You need the license active, the insurance current and verified at the source, and the names matching across all of it.

What are the red flags?

A few patterns come up again and again, and each one should slow you down.

• The contractor will not provide a license number, or says the license is pending.
• The license belongs to someone else, a relative, a former partner, or a friend the contractor is working under.
• The name on the license does not match the name on the contract or the payment instructions.
• The contractor suggests skipping permits to save time or money.
• The price is dramatically lower than every other bid, which often reflects missing insurance, missing licensing, or missing scope rather than generosity.

None of these guarantees a bad outcome. All of them shift the risk onto you, which is precisely what a good hiring process is designed to prevent. The license check works best as one layer in a broader vetting habit, alongside the interview itself. Our guide to the questions that separate good contractors from expensive ones covers what to ask once the paperwork clears, and how to vet a contractor for a larger project walks the full process end to end.

What do you do with what you found?

Save it. The license number, the date you verified it, the insurance certificate, the estimate, and eventually the contract and invoices all belong in one place, attached to your house rather than scattered across a text thread and a kitchen drawer. When the same contractor comes back in three years, or when a future buyer or insurer asks who did the work, you will have an answer instead of an archaeology project. Holm keeps your contractor history with the home, including who did what, when, and with which credentials verified.

There is a quieter benefit too. Contractors notice homeowners who are organized. Clear records, verified paperwork, and a documented scope tend to attract the professionals who run their own businesses the same way, and that sorting effect works in your favor long before any work begins.

A license check is ten minutes of light diligence that removes an entire category of bad outcomes. Do it every time, file what you find, and the whole relationship starts on solid ground. If you want a place where those records keep themselves organized, Holm is ready when you are.
