How to Vet a General Contractor in California: CSLB, Bonds, and Insurance

Vetting a general contractor in California takes about thirty minutes and costs nothing: verify the CSLB license at cslb.ca.gov, confirm the $25,000 contractor bond is active, get certificates for liability insurance and workers' compensation, and never pay a deposit larger than $1,000 or 10 percent of the contract price — whichever is less. Most remodel horror stories trace back to skipping one of those steps.

We are a licensed contractor writing a guide to checking up on licensed contractors, so the bias is obvious — and so is the reason we wrote it. Every homeowner who gets burned by an unlicensed or underinsured operator makes the next client's trust harder to earn for everyone doing this work properly. Here is the full checklist, in the order we would run it on ourselves.

How do you check a CSLB license?

Go to cslb.ca.gov and use the license check tool — you can search by license number, business name, or the individual's name. Every contractor in California performing work over a small-job threshold must hold a license from the Contractors State License Board, and for a whole-home remodel, an addition, or a custom home, the classification you want to see is Class B — General Building. A specialty classification like C-33 painting or C-10 electrical does not license someone to run your whole-house project.

Read the whole record, not just the green "active" status. Check that the business name on the license exactly matches the name on your contract and your checks — a mismatch means you are contracting with an entity that may not be licensed at all. Check the issue date to see how long the license has actually existed, check for disciplinary actions and citations, and confirm the bond and workers' compensation lines both show current on file. Ours is CSLB #1070537, and it is linked from our credentials page precisely so you can run this check on us without asking permission.

What does a contractor bond actually cover?

Every licensed California contractor must have a contractor bond on file — currently $25,000. Homeowners routinely hear "licensed and bonded" and picture meaningful protection, so here is the honest version: the bond is not insurance, and it is not sized to your project. It exists to pay claims when a contractor violates license law — abandons a job, takes payment for work never performed, does work so defective it breaches the contract — and the surety pays valid claims up to the bond amount, then collects from the contractor.

Now do the math against a whole-home remodel. If a contractor implodes mid-project with four jobs running, every affected homeowner, subcontractor, and employee is claiming against the same $25,000. On a $400,000 project, the bond might return pennies on the dollar of your loss. The bond check is still worth running — a contractor who cannot keep a bond in force is telling you something — but treat it as a licensing formality, not as protection. Your actual protection comes from the next three sections.

Liability insurance and workers' comp: whose risk is it?

Two separate policies, two separate risks. General liability insurance covers damage the contractor causes — the fire, the flood into the neighbor's yard, the beam through the wrong wall. Ask for a certificate of insurance naming you as certificate holder, sent directly from the contractor's insurance agent, and look for at least $1 million per occurrence on a remodel-scale project. A certificate photocopied from the contractor's own folder can be expired or doctored; one issued by the agent this week cannot.

Workers' compensation is the one where the homeowner personally carries the downside. California now requires licensed contractors to carry workers' comp coverage — the exemption that once let contractors simply declare they had no employees has been closed as the law has tightened through 2026. Here is why you should verify it anyway: if a worker is seriously hurt on your property and there is no valid comp policy behind them, the injured worker's recovery path can run toward you and your homeowner's policy — which likely excludes exactly this. A roofer with a broken back and no comp coverage is a life-changing lawsuit, and "he told me he was covered" is not a defense. The CSLB license record shows whether comp is on file; the certificate from the carrier confirms it is current.

What does California law say about deposits?

For home improvement contracts in California, the down payment is capped at $1,000 or 10 percent of the contract price, whichever is less. Read that again, because it surprises everyone: on a $300,000 remodel, the maximum legal deposit is $1,000. Not ten percent. One thousand dollars.

A contractor asking for $30,000 "to get you on the schedule" or "to order materials" before work begins is violating one of the clearest consumer protections in California contracting — and a contractor who needs your deposit to fund your materials is telling you they have no working capital, which is its own red flag. Legitimate payment schedules bill as work is performed and materials are delivered: you should always be paying for progress that has already happened, never funding progress that has not.

What are lien releases, and why should you care?

In California, subcontractors and suppliers who work on your house can record a mechanics lien against your property if they are not paid — even if you already paid your general contractor in full. You can pay for your remodel twice; it happens. The defense is paperwork: early in the job, subs and suppliers may send you a preliminary notice, which is not a lien and not a problem — it is them preserving their rights, and it usefully tells you who is actually working on your project.

Then, with every progress payment, collect conditional lien releases from the general and the major subs, and unconditional releases once each payment clears. A professional contractor's office produces these as a matter of routine and will never act put out by the request. A contractor who bristles at lien releases is either disorganized or not paying their subs — and both of those eventually become your problem.

A good contractor is never offended by verification. The ones who get offended are the reason verification exists.

What are the red flags?

Some patterns show up in nearly every contractor-disaster story. A discount for paying cash — cash pricing usually means unreported income, no paper trail, and often no valid license behind the work. No written, itemized scope — a one-page proposal for a six-figure project is not a bid, it is an invitation to dispute everything later. Pressure to sign today, prices that expire tonight, a deposit demand over the legal limit.

The subtler one is the borrowed license. California requires a qualifier — often a Responsible Managing Officer — behind every license, and there is a gray market of operators running crews under a license whose qualifier has never seen their jobsites. Signs: the name on the truck does not match the license, the person you have met is never the person on the CSLB record, the license is registered to an address two counties away. If the human beings running your project cannot be connected on paper to the license number they are trading on, walk away.

What do Google Guaranteed and NARI actually mean?

Both are real signals, neither replaces the checks above. Google Guaranteed means Google has verified the business's license and insurance and run background checks, and backs work booked through its platform with a limited reimbursement guarantee — useful screening, but the reimbursement cap is trivial against remodel budgets, and it is ultimately an advertising program. NARI — the National Association of the Remodeling Industry — is the remodeling industry's professional association; accreditation means a company has committed to its code of ethics and standards. It signals seriousness about the craft. It does not underwrite your project.

Treat both the way you would treat a well-kept jobsite: evidence of professionalism that earns a contractor a place on your shortlist, at which point you run the license, insurance, and payment-structure checks anyway. We hold both, alongside the license and coverage detailed on our credentials page.

The takeaway

License verified at cslb.ca.gov, Class B, name matching the contract. Bond active — understood as a $25,000 formality, not a safety net. Liability certificate from the agent, workers' comp confirmed current. Deposit at $1,000 or 10 percent, whichever is less, with payments tracking completed work. Lien releases with every check. That is thirty minutes of diligence against the largest check most families ever write to a private company. Any contractor worth hiring will pass every step without friction — our own design-build process is built to survive exactly this scrutiny.
