California Unlicensed Contractor Penalties Under SB 779

SB 779 raised California's minimum fine for unlicensed contracting from $200 to $1,500 per violation. What the new fines mean and how GCs must verify each sub.

By StateLicensePublished

The California unlicensed contractor penalty just got a lot more expensive. Starting July 1, 2026, the minimum civil penalty for working without a license in California jumps from $200 to $1,500 per violation, a 650 percent increase signed into law as Senate Bill 779. That is a floor, not a ceiling: the maximum stays at $15,000 per violation, and fines stack across projects and trade violations.

The bill also sets a $1,500 minimum for the violations Sacramento considers the most serious: aiding or abetting an unlicensed contractor, entering into a contract with an unlicensed person, and falsifying workers' compensation coverage. Everything else gets a $500 floor. And the Contractors State License Board (CSLB) can now adjust those minimums for inflation every five years, so the floor only rises from here.

If you are a general contractor, an owner, a lender, or anyone who awards or approves construction work in California, this is not a curiosity. It changes the economics of your pre-contract workflow. Here is what SB 779 did, why lawmakers did it, and what to do before you sign.

What did SB 779 change?

SB 779, authored by Senator Bob Archuleta and sponsored by the CSLB itself, amends sections 7028.7 and 7099.2 of the Business and Professions Code. The governor signed it October 1, 2025, and the new penalty schedule takes effect July 1, 2026.

The mechanics are straightforward:

  • Unlicensed activity: minimum civil penalty rises from $200 to $1,500 per violation; maximum remains $15,000. Penalties per violation can accumulate across multiple projects.
  • Serious violations: a new $1,500 minimum for aiding or abetting an unlicensed person, contracting with an unlicensed person, filing a false workers' compensation exemption, and failing to comply with building codes, among others.
  • General violations: a codified $500 minimum fine, up from $100 or $200 depending on the violation.
  • Inflation indexing: the CSLB may adjust minimum penalties based on the Consumer Price Index every five years.

One line from the legislative analysis captures the philosophy: the point of the minimums is to deter violations by making the penalty more expensive than compliance.

Why did California raise the minimum fines?

Because the old minimums had stopped working. The CSLB reported in its 2024 Sunset Report that between fiscal year 2019/20 and 2022/23, it issued $18,091,356 in fines across 5,597 citations, an average pre-appeal fine of $3,232. Then administrative law judges cut 2,014 of those fines on appeal to an average of $1,840, many down to the $100 regulatory minimum. The total reduction: $3,706,540, nearly a million dollars a year.

The bill's analysis was blunt about the incentive problem. The minimum civil penalty for unlicensed activity was $200, while a contractor license application runs about $450 plus fees. A $200 fine for getting caught is cheaper than getting licensed. CSLB-sponsored bill language called the reductions fines "not commensurate with the violation" and argued they failed to create any incentive to comply.

SB 779 flips that arithmetic. A $1,500 floor, indexed to inflation, means the cheapest possible citation now costs more than three times the license application.

What are the criminal penalties for unlicensed contracting in California?

Civil fines are only half the exposure. Under Business and Professions Code section 7028:

  • A first offense is a misdemeanor, punishable by up to 6 months in jail and fines up to $5,000.
  • A second offense carries a mandatory 90-day jail sentence.
  • Bidding or performing work under someone else's license number is a felony.

The CSLB runs sting operations across the state every year, pulling unlicensed operators off job sites and arresting them on the spot. For licensed contractors, the criminal exposure is mirrored in the civil schedule: the $1,500 minimum also applies to aiding or abetting unlicensed work and to contracting with an unlicensed person, so a GC that knowingly hires an unlicensed sub is in the penalty regime too.

What does SB 779 mean for GCs, owners, and compliance teams?

Three practical shifts:

  1. Pre-contract verification is no longer optional. The $1,500 minimum for contracting with an unlicensed person makes a missing license check an expensive oversight. Verify every sub's license status and classification before awarding the contract, not after the first invoice.
  2. Documentation matters. SB 517, a companion 2026 law, requires prime contractors to provide homeowners with subcontractor names, license numbers, and classifications on request. Build the habit of recording the qualification check: license number, classification, date, result, filed with the contract.
  3. Rechecks compound. Penalties apply per violation, so an unlicensed sub working across multiple phases of your project multiplies exposure. Recheck status before draw disbursements and at renewal dates, the same way lenders recheck before each funding release.

If you manage onboarding or draw schedules, the California rules plug directly into your existing checklist: our contractor onboarding verification checklist covers license, insurance, bond, and W-9 ownership in one place.

How do you verify a California contractor before awarding work?

A working checklist for each sub, before the contract is signed:

  1. Look up the license. Run the license number on the CSLB's Instant License Check or a normalized API like the California contractor license API. Confirm status reads "active," not suspended or expired. See the CSLB lookup guide for what each status means.
  2. Confirm the classification matches the work. A B general building licensee should not be doing C-10 electrical work. Misclassification is its own violation category.
  3. Check workers' compensation coverage, not just the exemption. Filing a false workers' comp exemption carries the $1,500 serious-violation minimum, and SB 291 separately tightened exemption verification in 2026. Read the coverage line, not the checkbox.
  4. Confirm the license bond is on file. California requires a $25,000 contractor license bond per classification, with a $100,000 additional bond for LLCs. A lapsed bond can suspend the license even when the status page looks fine at a glance. (State-by-state bond amounts are in our license bond requirements guide.)
  5. Record the check. Date, license number, classification, bond and comp status, who ran it. Attach it to the contract file so it is there when an owner, lender, or auditor asks.

At volume, this is where teams move from manual lookups to API-based verification: one call returns status, classification, bond, and insurance in a normalized schema, and scheduled rechecks catch lapses between draws. That is the whole product, but you do not need it to start; a spreadsheet and the CSLB check beat no check at all.

FAQ

Does SB 779 change what counts as unlicensed contracting?

No. It does not add new rules or redefine what is legal. It only changes the penalty amounts, raising the floors and adding inflation indexing.

Can a licensed contractor be fined under SB 779?

Yes. The $1,500 serious-violation minimum covers licensed-contractor conduct too: aiding or abetting an unlicensed person, contracting with an unlicensed person, filing a false workers' comp exemption, and failing to comply with building codes. General license-law violations get the $500 floor.

Do the new fines apply to past violations?

The new penalty schedule applies commencing July 1, 2026. Conduct cited on or after that date is under the new floors.

What if a sub's license was valid when I hired them but lapsed later?

That is exactly the scenario ongoing monitoring exists for. The license number on the contract proves nothing six months later. Recheck status at draw milestones and set a calendar reminder at each license expiration.

The bottom line

California decided that a $200 minimum fine was a rounding error and that the appeals process was turning citations into discounts. SB 779 answers both: a $1,500 floor for unlicensed activity, $1,500 for the serious violations that put consumers and honest contractors at risk, $500 for everything else, all indexed to inflation. The cheapest move in California construction is now the compliant one: verify the license, confirm the classification and coverage, and write down that you did.
