Can an Unlicensed Contractor Get Paid in California?

A completed job. A signed contract. An invoice sitting in the client’s inbox. And then one question stops payment cold: was the contractor properly licensed the entire time?

For California contractors, that single detail can decide whether the work gets paid or written off. If you are worried about an expired license, a renewal that slipped, or a client who learned about a lapse and is refusing to pay, the rules under California Business and Professions Code Section 7031 can hit hard.

A construction law attorney in Santa Rosa can walk you through what applies to your specific situation, but the basics below are worth knowing first.

Key Takeaways

• California requires a contractor’s license for most projects valued at $1,000 or more in combined labor and materials.
• Under Business and Professions Code Section 7031, an unlicensed contractor generally cannot sue to recover payment, even for finished work.
• A customer who hired an unlicensed contractor can usually sue to recover every dollar paid, through a disgorgement action.
• A mid-project lapse can still bar recovery unless the contractor meets the narrow “substantial compliance” exception.
• Unlicensed contractors cannot enforce a mechanic’s lien in California.
• Minimum fines for unlicensed contracting rose to $1,500 per violation on July 1, 2026 under SB 779.

When California Requires a Contractor’s License

The Contractors State License Board (CSLB) oversees contractor licensing in California.

A current CSLB license is required for any project where combined labor and materials reach $1,000 or more.

That threshold went up from $500 to $1,000 on January 1, 2025, under Assembly Bill 2622.

A few other triggers also require a license, regardless of the dollar value:

• The job requires a building permit.
• The work falls into a classification like roofing (C-39), where a license is required at any value.
• The contractor hires employees for the project.

Splitting an $1,800 job into two $900 invoices does not avoid the rule. CSLB looks at the project as a whole, not how it was billed.

How License Status Decides Whether You Get Paid

California Business and Professions Code Section 7031 is one of the toughest contractor payment statutes in the country.

• Section 7031(a) blocks any unlicensed contractor from suing to collect payment for work that required a license.
• Section 7031(b) lets the customer sue to recover every dollar they already paid, even if the work was done well.

Section 7031 is applied strictly by California courts. The customer does not need to prove bad workmanship or financial loss. If the license was not valid during the work, the contractor usually loses the right to collect and may owe money back, regardless of how the project turned out.

That means a contractor can finish a $200,000 remodel, deliver quality work, pass inspection, and still lose the right to collect what is owed. Worse, the customer can turn around and demand the money back under a disgorgement claim.

What Happens If Your License Lapsed Mid-Project

The default rule under Section 7031 is harsh: the contractor must be properly licensed at all times during performance.

A gap, even a short one, can bar recovery for the entire project.

Common causes of mid-project lapses:

• A renewal application was submitted late or returned by CSLB.
• The required contractor bond lapsed or was canceled.
• Workers’ compensation coverage dropped (will soon be required for all license classifications as of January 1, 2028).
• The qualifying individual (RMO or RME) left the company and was not replaced in time.
• A suspension triggered by an unpaid judgment or CSLB action.

There is a narrow exception called substantial compliance under Section 7031(e). A court may allow limited recovery when all of the following are true:

• The contractor had been properly licensed before performing the work in question.
• The contractor acted reasonably and in good faith to maintain proper licensure.
• The contractor did not know, and reasonably should not have known, they were unlicensed during performance.
• The contractor acted promptly and in good faith to reinstate the license after learning of the issue.

Each prong is a hurdle. Courts have denied substantial compliance for contractors who missed renewal deadlines, lost a qualifier without a replacement, or ignored CSLB notices. The exception exists, but it is not a safe fallback.

Can an Unlicensed Contractor File a Mechanic’s Lien?

No. A valid mechanic’s lien in California requires a licensed contractor where a license is required for the work. Recording a lien without a valid license can create more trouble, not less. It can expose the contractor to:

• Claims for slander of title
• Penalties for a false or improper recording

If a lien has already been recorded during a period when the license was not valid, the right next step is a prompt call to a construction attorney before the problem compounds.

The same rule applies to stop notices and other California statutory payment tools: valid license, or no leverage.

Disgorgement Claims Under Section 7031(b)

Section 7031(b) gives the customer a direct cause of action against an unlicensed contractor to recover all compensation paid for the work. The customer can bring this claim even if the work was:

• Finished
• Inspected
• In use

The one-year statute of limitations for a 7031(b) action generally runs from completion or cessation of the work. That claim is often paired with other theories:

• Unfair business practices under Business and Professions Code Section 17200
• Contractors State License Law complaints
• Workers’ compensation enforcement if employees were involved

The exposure stacks.

If you are a contractor on the receiving end of a disgorgement letter, do not assume the claim will go away because the work was good. Section 7031(b) does not care.

The Narrow Exceptions

A handful of situations fall outside Section 7031’s reach:

• Work under the licensing threshold. Projects where the total labor and materials cost stays under $1,000, with no permit required and no employees, can be performed without a CSLB license under the minor work exemption (BPC § 7048).
• Owner-builder work on your own property, subject to the owner-builder restrictions and the four-year resale rule for improvements.
• Certain federally governed work on federal land or installations where state licensing does not apply.
• Specific exempted trades, such as some mural artists and gardeners performing non-licensed tasks.

None of these exceptions help a contractor who performed licensed-category work above the dollar threshold without a current CSLB license. If your situation looks close to an exception, confirm it with a construction law attorney before relying on it.

When to Consult a Construction Law Attorney

Several moments justify picking up the phone:

• A client has refused payment and raised your license status as the reason.
• You discovered a renewal gap after the project was complete.
• You received a disgorgement demand letter from a former customer.
• You are a customer who hired a contractor and later learned the license was expired or never valid.
• Your qualifier left mid-project, and you are unsure whether you remained properly licensed.
• A mechanic’s lien you recorded is being challenged on licensing grounds.
• Your license was briefly suspended for a bond or workers’ compensation issue, and work continued during the gap.

Early advice can preserve defenses, lock in evidence of substantial compliance, and sometimes stop a disgorgement claim before it reaches litigation. Waiting until a complaint is filed narrows the options.
