How to check if a contractor is licensed and insured

“How do I check if a contractor is licensed and insured?”

“Should I ask to see their insurance before I hire them?”

“What if a contractor won’t show me their license?”

The honest answer is simpler than it looks: there’s no single website that tells you whether a contractor is licensed and insured. So the most reliable way to check is also the simplest — ask the contractor directly, right along with the estimate.

The rest of this explains why no database can do it for you, and how to ask so you actually get a straight answer.

Why there’s no single place to look

A few things about how licensing and insurance actually work — and together, they’re why there’s no universal lookup:

Licensing is handled at different levels. Sometimes it’s the state, sometimes the county, sometimes the city. There’s no single national database that covers all of it.

Not every trade is licensed — and the state isn’t always the one doing it. Take Ohio. The state board, the Ohio Construction Industry Licensing Board, licenses only five trades — electrical, HVAC, plumbing, hydronics, and refrigeration — and those carry a state license statewide, on residential jobs as much as commercial ones. But there’s no statewide license for a general contractor or home-improvement contractor at all; that’s left to individual cities. So a perfectly legitimate remodeler might have no “state license” simply because Ohio doesn’t issue one.

A license and a registration aren’t the same thing — and sometimes the registration is the license. In some places a license means passing an exam; in others, registering with the city (usually with a bond and insurance) is the actual permission to do the work. In Ohio, Columbus requires a home-improvement license with an exam, while Cincinnati and Cleveland require registration instead. Which one legally matters depends on the city and the trade — so the real question isn’t “are they licensed?” but “do they have what my area requires for this work?”

And insurance is usually private. Workers’ comp and liability generally aren’t public records you can search. (Ohio is the exception — workers’ comp runs through the state there, so it’s on record.) In most places, the only way to confirm insurance is to ask for it.

So the job isn’t “find the one right database.” It’s “confirm this contractor, in this place, for this work” — and that comes down to asking.

How to ask — the right way

Add one line when you’re getting a quote: “Could you send a copy of your license and insurance over with the estimate? I just like to have everything on file before we get started.” Asked as part of the normal paperwork, it doesn’t come across as alarming or accusatory — it’s the kind of thing professional contractors get asked all the time.

And how you ask matters more than people think. There’s a real difference between confirming something for peace of mind and demanding it. You’re a potential customer, not an inspector — and a business is allowed to decline to work with you. Come across as someone who’ll be a headache, and a good contractor might quietly pass on the job.

So ask nicely, then use the simplest filter there is: the ones who send it over without a fuss are the ones you keep talking to. The ones who can’t or won’t are the ones you move on from. That one habit does more than any database.

If you’d rather verify it yourself

Asking is fastest, but you can confirm a license independently too:

• Search “[your state] [trade] license verification” — like “Ohio plumbing license verification.” Most states and cities put these lookups online. Some contractors even display the number right on their work truck.
• Call your city’s building department and ask whether the company is a registered contractor.

Just know it’s hit or miss — not every place has an online lookup, and (as above) insurance usually can’t be verified this way at all. Which is exactly why asking stays the reliable route.

Why it’s worth the two minutes

None of this is busywork. Hiring an unlicensed or uninsured contractor isn’t just a paperwork problem:

• An unlicensed contract can be unenforceable — leaving you no legal footing if the work is defective or they walk off.
• If an uninsured worker gets hurt on your property, you can be on the hook for their medical bills.
• Some homeowners policies won’t cover damage from work done by an unlicensed contractor.

A contractor who’s real and accountable will show you their license before you’ve finished the sentence — and all else equal, that’s the one you want.

All that said — none of this is a rule you’re obligated to follow. If you know the person, or the price is right and you’ve weighed the risk and decided it’s worth it, that’s entirely your call. It’s your money and your house, and nobody else gets to decide what you do with them. The point was never only ever hire the licensed and insured — it’s that you go in knowing what you’re choosing, so it’s a decision you made on purpose and not a surprise you find out about later.
