Hiring a contractor means handing someone access to your home and a lot of your money. The single easiest way to protect yourself takes about five minutes and costs nothing: check their license. Yet plenty of homeowners skip it, and unlicensed work is one of the most common reasons projects end badly.
Here is exactly how to verify a California contractor, what the results mean, and a handful of red flags worth knowing. We will use our own license as the example, so you can see what a clean result looks like.
Step by step: the CSLB license lookup
In California, contractors are licensed by the Contractors State License Board, known as the CSLB. Anyone doing work worth $1,000 or more in labor and materials generally needs a license. Their online lookup is free and public.
- Go to the CSLB website and find the license check tool.
- Enter the contractor's license number. If they will not give you one, that is your first answer.
- Confirm the business name on the record matches the name on your contract and the truck.
- Check that the license status says active, not expired, suspended, or cancelled.
- Read the classification, bond, and workers compensation information on the page.
- Scroll down and look for disciplinary actions or complaints.
As an example, Pacific Home Exteriors is licensed under CSLB License #1160357. You can type that number into the lookup and see for yourself. We encourage every homeowner to do this with any contractor, including us.
A few tips make the lookup more reliable. Search by license number rather than by name, since similar business names are common. If a number does not appear, double-check the digits before assuming the worst. And save a screenshot or printout of the record on the day you sign, so you have a snapshot of the status, bond, and classification at the time of your contract.
Classification: is this the right license for the job?
California contractors hold specific classifications. A general building contractor holds a Class B license, and specialty trades hold their own, such as roofing, painting, or landscaping. The classification on the record should match the work in your contract. A company licensed in one trade is not automatically licensed for another.
Many companies, including ours, manage a project as the licensed contractor while vetted specialist crews handle the trade work. That is a normal and legitimate structure when it is done properly. The key question is who is accountable. Ask who is responsible for the work, who carries the insurance, and who you call if something goes wrong. Pacific's answer is simple: one accountable team manages the project from start to finish.
Bond and workers compensation
Two items on the CSLB page matter a great deal:
- The contractor's bond. California requires a license bond, which gives homeowners a way to seek recovery in certain situations of loss. It is a safety net, not a guarantee, but its absence is a serious problem.
- Workers compensation. The record should show current coverage, or a valid exemption. If someone is injured on your property and the contractor has no coverage, a homeowner can face serious exposure. Ask for a certificate of insurance and confirm it is current.
Liability insurance is separate. A reputable contractor will gladly provide proof of both and will not be offended that you asked.
The deposit rule every homeowner should know
California law caps a home improvement deposit at $1,000 or 10 percent of the contract price, whichever is less. That is the maximum a contractor may legally ask you to put down before work begins. Payments after that should be tied to actual progress, not pulled ahead of the work.
If a contractor asks for half the job up front, or says there is a "special price if you pay in cash today," you have just spotted a red flag. Keep payments traceable, get receipts, and make sure the payment schedule in the contract matches what you were told. For a roof or other large job, spreading payments over time can be easier on the budget. We offer flexible monthly payments for qualified homeowners, always explained in writing before you commit.
Red flags to watch for
- No license number on the estimate, the truck, or the ads. California requires it on advertising.
- Pressure to sign today, or a price that disappears after you leave.
- A very large deposit, or a request to pay cash only.
- Door-to-door storm chasers with out-of-area plates who show up after a heavy Southern California rain or a Santa Ana wind event.
- No written scope, or a scope that is vague about materials and what is included.
- Pulling permits in your name as "owner-builder" when a licensed contractor should be doing it.
- A contract that starts work immediately without the required notices and your right to cancel.
Good contractors do the opposite. They give you time, put everything in writing, and explain the process in plain English. If you want to see what our process looks like, read what to expect at a free roof inspection.
Putting it together
It also helps to ask a few plain questions on the phone before anyone comes to your home. Do you carry workers compensation? Who pulls the permit? Will I get a written scope with materials listed? A confident contractor answers all of these in a sentence or two. Hesitation, vague answers, or irritation at your questions tell you something too.
A license check is not the whole story, but it is the best first filter. After that, compare written scopes, ask for references, and trust your instincts about how you are treated.
