Can a California Contractor Work With an Expired License?

No. In California, working with an expired contractor license is treated the same as working without a license at all.

The Contractors State License Board (CSLB) is explicit: any work performed while a license is expired is considered unlicensed contracting, and disciplinary action can be taken. That applies even if your renewal is sitting in a processing queue. If the license shows expired, the work is unlicensed.

What happens when your California contractor license expires?

The moment your CSLB license expires, you lose the legal authority to perform work that requires a contractor license in California. That means you should not:

• Sign new contracts
• Pull permits as a licensed contractor
• Advertise yourself as a licensed contractor
• Perform work requiring a contractor license

Even if a renewal application has already been submitted, the CSLB considers work performed while the license shows as expired to be unlicensed contracting.

Criminal charges

Contracting without a license — which includes contracting with an expired license — is a misdemeanor under Business and Professions Code Section 7028. First-conviction penalties include up to six months in jail and/or a fine of up to $5,000. A second conviction carries a mandatory 90-day jail sentence. Penalties increase with each successive violation.

The CSLB’s Statewide Investigative Fraud Team (SWIFT) runs undercover sting operations across California every week. Contractors with expired licenses have been cited in these operations.

Administrative fines

On top of criminal exposure, the CSLB can impose an administrative fine of $200 to $15,000 for unlicensed contracting. Criminal and administrative penalties aren’t mutually exclusive — both can apply to the same violation.

You can’t collect what you’re owed

Business and Professions Code Section 7031 bars a contractor from bringing any action to collect compensation for work performed without a license. No license at the time of performance means no legal right to get paid — even if the work was done competently and the client accepted it.

Under BPC §7031, a client can sue to recover all money already paid to a contractor who wasn’t properly licensed when the work was performed. A completed job, fully paid, can still result in the contractor having to return every dollar.

The renewal process and the 90-day window

Expired licenses don’t disappear. You can renew at any time within five years of the expiration date — but a delinquent fee applies, and any work performed in the gap is still treated as unlicensed. Submitting a renewal application doesn’t restore your license. If the CSLB hasn’t processed it by your expiration date, the license shows as expired and any work done in the meantime is unlicensed contracting.

Under SB 1474, the CSLB is required to retroactively reinstate an expired license if a completed renewal application is received within 90 days of the expiration date — effectively eliminating the gap in licensure. To qualify, you must submit a written petition showing the delay was due to circumstances beyond your control. It’s not automatic and it’s not guaranteed.

If your license has been expired for more than five years, renewal isn’t an option. You must file an Application for Original Contractor’s License and retake the law and trade portions of the written examination.

Don’t rely on a renewal notice

California law puts the responsibility on the licensee. The CSLB sends renewal notices, but if yours gets missed during a busy season, a move, or an address change, that’s not a defense. Tracking your expiration date is your responsibility.
