What Are the Consequences of Hiring an Unlicensed Contractor in California?

The Hidden Risks You Take On When a Contractor Isn't Licensed

Most homeowners assume that if something goes wrong, the legal system will make it right. But when your contractor has no license, the biggest dangers are the ones no lawsuit can undo — injuries, uninsured damage, and liability that lands directly on you.

A licensed California contractor must carry three layers of protection: liability insurance, workers' compensation coverage, and a license bond. An unlicensed contractor has none of them, which is why legal analysts warn that hiring one can leave you "financially exposed, and personally liable for injuries on your property" (Mellor Law Firm).

That personal liability is the risk homeowners understand least. If a worker falls off your roof or is injured on your property and carries no workers' compensation coverage, you may be the one facing the claim. Your homeowner's policy may not respond the way you expect, and there is no bond to fall back on.

• No liability insurance — damage to your home or a neighbor's property comes out of your pocket.
• No workers' compensation — an injured worker's only target may be you, the property owner.
• No license bond — the recovery mechanism that exists for licensed-contractor disputes simply isn't there.
• No building-permit accountability — unlicensed operators often skip permits entirely, leaving you with unpermitted work.

For Altadena homeowners, the stakes are especially high right now. ADUs, major remodels, and fire rebuilds are exactly the kind of large, permit-heavy projects that can never qualify for California's small-job exemption — unlicensed work is legal only for jobs under $1,000 in combined labor and materials, with no permits and no additional workers (The Mountain Messenger). Every rebuild or ADU project will far exceed that threshold.

There's also a trap most people never see coming: a contractor whose license lapses mid-project is treated as unlicensed for that period, and even the wrong license classification — say, a painter performing electrical work — triggers the same consequences (Bay Legal). Out-of-state licenses carry no weight in California at all.

The good news is that verification takes minutes, not days. The California Contractors State License Board regulates roughly 285,000 contractors statewide, and its records are public. Altadena Builder Directory provides a free CSLB license-lookup tool so you can confirm any contractor's status before signing, and every listing in the directory — from ADU builders to fire-rebuild specialists — is verified against CSLB records, with a verification seal shown once a license match is confirmed.

Money can sometimes be recovered after a bad hire. An injury on your property, or an uninsured catastrophe during a rebuild, often cannot. Checking the license first is the only protection that works before the damage happens.

California's Strongest-in-the-Nation Penalties: What the Law Says Now

If you hire an unlicensed contractor in California and the work turns out perfect, you might assume you're stuck. You're not — the law lets you recover every dollar you paid, even for flawless craftsmanship.

That remedy is called disgorgement, and it comes from Business and Professions Code §7031(b). Courts have been explicit that it functions as a penalty, not compensation: the Court of Appeal in Eisenberg described it as depriving the contractor of any compensation for labor and materials while the homeowner keeps the benefit of the construction. The public interest in deterring unlicensed work, courts reason, outweighs the harsh result for the contractor.

The protections stack up quickly for homeowners:

• Unlicensed contractors cannot sue you for payment — the CSLB's official position is that consumers are not legally required to pay someone who is not state-licensed.
• Their contracts are treated as void by California courts.
• They have no mechanic's lien rights, so they cannot place a lien on your home.
• The contractor personally faces criminal exposure: a misdemeanor carrying up to 6 months in jail and a $5,000 fine for a first offense, with felony charges possible for contracting in a state or federal disaster area without an active license.

California is now raising the stakes even further. Under SB 779, the minimum civil penalty for unlicensed activity jumped from $200 to $1,500 per violation — a 650% increase — with maximums reaching $15,000, or $30,000 for willful violations. The legislature acted because 2,014 enforcement fines totaling more than $3.7 million were reduced on appeal between FY 2019-20 and 2022-23, and some contractors treated fines as a cost of doing business. SB 779 was sponsored by the CSLB and passed both chambers unanimously.

There's one recent relaxation worth understanding. Under AB 2622, the handyman exemption threshold doubled from $500 to $1,000 in combined labor and materials. But the exemption is narrow: no building permits, no extra workers, no splitting a larger project into sub-$1,000 pieces, and unlicensed handymen who advertise must disclose that they're unlicensed.

For Altadena homeowners, that exemption is effectively irrelevant. Any ADU, remodel, or fire-rebuild project will far exceed $1,000 — meaning a licensed contractor isn't just recommended, it's the only legal path. That's why every listing in the Altadena Builder Directory is verified against CSLB records, and why the directory offers a free license-lookup tool so you can check any California contractor in minutes before signing anything.

One warning: this protection has a deadline. The disgorgement claim must be filed within one year of the work's completion, and the delayed-discovery rule does not apply. In Eisenberg, a claim filed more than five years after completion was barred entirely. If you've paid an unlicensed contractor, the clock may already be running.

The One-Year Clock: How to Recover Your Money If You Already Hired Someone Unlicensed

Good news first: if you paid an unlicensed contractor, California law lets you claw back every dollar. The catch? You have exactly one year to do it — and the clock may have started before you even knew there was a problem.

The one-year deadline runs from completion of work — period. Under Business and Professions Code §7031(b), a homeowner can demand "disgorgement" of all money paid to an unlicensed contractor, even if the work was performed flawlessly. But California courts treat disgorgement as a penalty rather than compensation, and penalties carry short deadlines. In the Eisenberg case, the Court of Appeal barred a claim filed more than five years after a 2010 project was completed, holding that the one-year statute of limitations runs from completion or cessation of work — not from when the homeowner discovered the contractor lacked a license.

That last point trips up a lot of homeowners. California's "delayed-discovery" rule — which typically pauses the clock until you discover the harm — does not apply to disgorgement claims. If your contractor finished the job in March and you learned in December that the license was fake, you had until the following March, not the following December.

Two other misconceptions can derail your recovery:

• Disgorgement is not treble damages. You recover what you paid — all of it, but not triple. Enhanced or multiplied damages arise only under separate laws, such as those protecting senior or disabled victims, per legal analysis of §7031 remedies.
• The CSLB cannot order repayment. The Contractors State License Board is a regulator — it can fine, suspend, and pursue criminal referrals, but recovering your money requires filing a separate civil claim.
• Filing a CSLB complaint is still worthwhile for enforcement, but don't mistake it for a refund request — the two processes are entirely separate.

The practical takeaway: the moment you suspect a contractor was unlicensed, verify the license and talk to a construction attorney immediately. A quick check through Altadena Builder Directory's free CSLB license-lookup tool can confirm licensure status in minutes, so you know where you stand before the one-year window closes. Waiting is fatal to the claim — in Eisenberg, the homeowner lost everything by sitting on their rights.

Your Five-Minute Protection Plan: Verify Before You Sign

You can undo a bad paint color. You cannot easily undo a contract signed with an unlicensed contractor — but you can prevent it entirely with five minutes of checking before you sign anything.

Step one: run the license lookup. The California Contractors State License Board regulates roughly 285,000 contractors across the state, and its records are free to search. A five-minute license check before signing can protect you from months of costly problems, so confirm the license is active, matches the name on your contract, and covers the work being quoted.

Step two: watch for the trap scenarios that catch even careful homeowners. A license can lapse mid-project — even a brief suspension can disqualify the contractor under California's disgorgement rules. Classification matters too: a C-33 painting license does not authorize C-10 electrical work, and hiring someone outside their classification puts you in the same legal position as hiring someone with no license at all. Finally, remember that out-of-state licenses carry no reciprocity in California — a contractor licensed in another state is, for legal purposes, unlicensed here.

Step three: structure your payments defensively. The CSLB advises that down payments should not exceed 10% of the contract price, with later payments never exceeding the value of completed work or delivered materials. This keeps your exposure limited at every stage of the job — and it applies whether or not the contractor turns out to be licensed.

Step four: know the small-job exception so you don't misapply it. Under AB 2622, unlicensed work is legal only for projects under $1,000 in combined labor and materials, with no building permit and no additional workers — and contractors cannot split a larger project into sub-$1,000 pieces to dodge the rule. Any ADU, remodel, or fire-rebuild in Altadena will far exceed that threshold and requires a licensed contractor.

A few red flags worth memorizing:

• The contractor asks for more than a 10% down payment or cash-only terms.
The license number on the bid doesn't match the CSLB database or the business name.The work requires a permit, but the contractor suggests pulling it yourself.The bid arrives without a written contract, license number, or insurance details.The contractor claims an out-of-state license "counts" in California.

If verification feels like a chore, it doesn't have to be. The Altadena Builder Directory is a free, independent registry where every listing is license-verified against CSLB records — listings display a verification seal once a license match is confirmed, and ratings come only from real attributed public sources. You can also use the directory's free CSLB license-lookup tool to verify any California contractor yourself, not just those listed. (One listing, JMB Builders LLC, CSLB #1103479, appears as a labeled paid placement — the labeling itself is part of the directory's transparency policy.)

Verification takes minutes. Recovering money from an unlicensed contractor takes a lawsuit — and under California's one-year deadline, you may not get that chance at all.
