BPC §7031: Why Unlicensed Contracting Bars You From Getting Paid

Section 7031 is the provision that makes licensure a financial issue rather than an administrative one. It has been described by courts as both a shield and a sword: subdivision (a) prevents a contractor from suing for payment, and subdivision (b) lets the person who hired them affirmatively recover what was already paid. Neither turns on the quality of the work. This guide, reviewed by Jayson R. Elliott, reads both halves and the narrow exception that can reach them.

The shield: §7031(a)

Section 7031(a) provides that, except as provided in subdivision (e), no person engaged in the business or acting in the capacity of a contractor may bring or maintain any action, or recover in law or equity in any action, in any court of this state for the collection of compensation for the performance of any act or contract where a license is required by the chapter — without alleging that they were a duly licensed contractor at all times during the performance of that act or contract, regardless of the merits of the cause of action. The subdivision carries a narrow carve-out for contractors who are each individually licensed but who fail to comply with section 7029.

"At all times during the performance"

This phrase does the most damage in practice. The requirement is continuous, not point-in-time. A contractor licensed when the contract was signed and licensed when the work was finished, but whose license lapsed for a period in between, has not been licensed at all times during performance.

Lapses of this kind are usually administrative rather than deliberate — a renewal missed, a bond that did not get replaced, a suspension for an unpaid penalty that the contractor did not register as affecting license status. The statute does not distinguish by cause. This is the direct link between the license-status points on the licensing hub and the suspension guide and the money on a project.

"Regardless of the merits"

The statute says so expressly. It does not matter that the work was performed competently, that the owner is satisfied, that the value was delivered, or that the balance is plainly owed under the contract. Courts apply section 7031 strictly because the Legislature designed it as a deterrent aimed at licensure compliance, not as a remedy calibrated to fault or to unjust enrichment.

The sword: §7031(b)

Section 7031(b) provides that, except as provided in subdivision (e), a person who utilizes the services of an unlicensed contractor may bring an action in any court of competent jurisdiction to recover all compensation paid to the unlicensed contractor for performance of any act or contract.

As the Court of Appeal put it in White v. Cridlebaugh (2009) 178 Cal.App.4th 506, the Legislature complemented the shield in subdivision (a) by adding, in 2001, a sword permitting those who use unlicensed contractors to recover compensation paid for the unlicensed work.

Note the word “all.” The subdivision is not written as a measure of damages tied to defective work or to amounts overpaid. It reaches compensation paid for performance of the act or contract.

Why both halves can hit the same project

The two subdivisions are not alternatives, and understanding that is the point of this page.

Consider a project where a contractor has been paid progress payments and is owed a final balance when a licensure defect surfaces. Subdivision (a) addresses the balance: an action to collect it faces the bar. Subdivision (b) addresses the progress payments: they are what the customer may sue to recover. The contractor is not merely unpaid for the remainder — they are exposed on what they already banked and spent.

The two halves, side by side §7031(a) — the shield: blocks the contractor’s action to collect compensation, regardless of the merits. §7031(b) — the sword: lets the customer sue to recover all compensation already paid. Both are expressly subject to the subdivision (e) substantial compliance exception, and only that exception. Neither depends on the quality of the work.

Who has to prove licensure

Section 7031 also addresses proof. Where licensure or proper licensure is controverted, proof of licensure must be made by producing a verified certificate of licensure from the Contractors State License Board establishing that the individual or entity bringing the action was duly licensed in the proper classification at all times during performance. The party controverting licensure is not required to produce a verified certificate — and when licensure or proper licensure is controverted, the burden of proof to establish it rests on the licensee.

Two consequences follow. Raising the licensure issue is inexpensive for the opposing party. And “proper classification” is part of what must be established, so working outside the classification held is a licensure question and not merely a scope question.

The one way out: substantial compliance

When the doctrine is unavailable entirely

Subdivision (e) begins by closing the door on the hardest facts: the judicial doctrine of substantial compliance shall not apply under this section where the person who engaged in the business or acted in the capacity of a contractor has never been a duly licensed contractor in this state. Someone who never held a California license has no path here.

The three-element path

For everyone else, subdivision (e) permits the court — notwithstanding section 143(b) — to determine that there has been substantial compliance with licensure requirements if it is shown at an evidentiary hearing that the person: (1) had been duly licensed as a contractor in this state prior to the performance of the act or contract; (2) acted reasonably and in good faith to maintain proper licensure; and (3) acted promptly and in good faith to remedy the failure to comply with the licensure requirements upon learning of the failure.

Three features of that test are worth reading closely. It requires an evidentiary hearing, so it is not resolved on the pleadings. All three elements are conjunctive. And the second and third are both good-faith conduct standards measured by what the contractor actually did — before the lapse, in trying to maintain licensure, and after discovering it, in fixing it.

The third element is the one a contractor has the most control over after the fact. Prompt, documented remediation on learning of a lapse is the conduct the statute rewards; delay while the dispute develops is not.

What this means practically

Contractors whose license status is affected by a disciplinary matter should read the suspension and revocation guide alongside this one, since a suspension raises this exact question for any work performed during it.

Before you ask

Questions contractors ask first.

Can an unlicensed contractor sue for payment in California?

No. Business and Professions Code section 7031(a) bars any person engaged in the business or acting in the capacity of a contractor from bringing or maintaining an action to collect compensation for work requiring a license without alleging they were duly licensed at all times during performance — and it applies regardless of the merits of the claim.

Can a customer get their money back from an unlicensed contractor?

Yes. Business and Professions Code section 7031(b) permits a person who utilizes the services of an unlicensed contractor to bring an action to recover all compensation paid to that contractor for performance of the act or contract. As the court explained in White v. Cridlebaugh (2009) 178 Cal.App.4th 506, this “sword” was added by the Legislature in 2001 to complement the payment bar.

What if a contractor's license lapsed only briefly during a project?

Business and Professions Code section 7031(a) requires licensure “at all times during the performance” of the act or contract, so a gap during performance is a gap regardless of its length or cause. The only route around it is the substantial compliance exception in subdivision (e), which requires an evidentiary hearing and proof of three conjunctive elements.

What is the substantial compliance exception under §7031(e)?

Business and Professions Code section 7031(e) allows a court to find substantial compliance if it is shown at an evidentiary hearing that the person had been duly licensed in California prior to performance, acted reasonably and in good faith to maintain proper licensure, and acted promptly and in good faith to remedy the failure upon learning of it. The doctrine does not apply at all to someone who has never been duly licensed in California.

Who has the burden of proving licensure under §7031?

Business and Professions Code section 7031 places the burden on the licensee. Where licensure or proper licensure is controverted, proof must be made by producing a verified certificate of licensure from the Contractors State License Board showing the party was duly licensed in the proper classification at all times during performance, and the party controverting licensure need not produce a certificate of its own.

Does §7031 apply if the work was done well?

Yes. Business and Professions Code section 7031(a) applies “regardless of the merits of the cause of action,” so the quality of the work, the satisfaction of the customer, and the value delivered do not change the analysis. The provision is directed at licensure compliance rather than at fault.
