The contractor was not licensed — what that does to the money

Two people read the same licence record and take opposite lessons from it. The homeowner sees a reason not to pay the final invoice. The contractor sees an administrative slip on a job that was built properly. Neither reading is quite right, because a licensing statute does not weigh the work at all — it decides, in advance, who is allowed through the courtroom door.

The licence is decided before the workmanship is

California’s Business and Professions Code § 7031(a) is the sharpest version. No person acting in the capacity of a contractor may bring or maintain any action for the collection of compensation for work requiring a licence "without alleging that he or she was a duly licensed contractor at all times during the performance of that act or contract regardless of the merits of the cause of action brought by the person". Subdivision (c) closes the side door: a security interest taken to secure that payment is unenforceable on the same facts.

The same architecture appears in states that are otherwise nothing alike. Washington’s RCW 18.27.080 bars any action for compensation or for breach of contract without alleging and proving current registration at the time of contracting. Arizona’s A.R.S. § 32-1153 requires a licence both when the contract was entered into and when the cause of action arose. Florida Statutes § 489.128 declares the contract itself "unenforceable in law or in equity by the unlicensed contractor" and denies any lien or bond claim.

The contractor’s failure mode is arguing the merits into a hearing that never reaches them. The customer’s is assuming the number on the letterhead settles it: once licensure is put in issue in California, § 7031(d) requires proof by a verified certificate of licensure from the Contractors State License Board, covering the whole period of the work.

Which work needs a licence, and where the small-job line sits

There is no national answer, and the variation is not a detail. Texas has no statewide general contractor or remodeller licence at all — electrical, plumbing and air conditioning are licensed by the Department of Licensing and Regulation, and everything else is a matter of city registration. New York has no statewide scheme either, but New York City and several suburban counties licence home improvement contractors, and that local licence carries the full bar. Washington registers every contractor with no dollar floor beneath it.

California licences from a very low number, and the number moved recently. Section 7048 exempts work where the aggregate contract price for labour, materials and all other items is under $1,000, the work is casual, minor or inconsequential, and no building permit is required. That figure was $500 until Assembly Bill 2622 raised it on 1 January 2025, so much published guidance is a year out of date. The exemption is also easier to lose than to rely on: it is unavailable where the job is part of a larger operation, where a contract has been divided to get under the threshold, where the person advertises as a contractor, or where they employ anyone to help.

Quantum meruit is the argument everyone tries

The instinct is strong and it is wrong: if the contract is unenforceable, surely the contractor is at least owed the reasonable value of the labour and materials. Every one of these statutes was drafted with that argument in view. Florida’s wording — "in law or in equity" — exists to kill it, and New York’s Court of Appeals held in B & F Bldg. Corp. v. Liebig that a contractor unlicensed while the work was done forfeits recovery under the contract and in quantum meruit alike, and that a licence obtained after suit begins cannot validate what was prohibited when performed. Hydrotech makes the same point from the other direction: renaming the claim — restitution, unjust enrichment, promissory estoppel, fraud — does not move it out of the statute.

California’s clawback: all of it, no offset, one year

Section 7031(b) has no real equivalent elsewhere. A person who utilises the services of an unlicensed contractor may sue "to recover all compensation paid to the unlicensed contractor for performance of any act or contract". Not the overpayment, not the gap between price and value — all of it, with the improvement left in place. The Court of Appeal in Eisenberg Village described a remedy that operates "without reference to the actual damage sustained" and hands the plaintiff a windfall regardless of any fault in the work, which is why it counts as a penalty rather than restitution.

Two consequences get missed. A customer who knew perfectly well the contractor was unlicensed still recovers — the holding in Alatriste, where the homeowner had been told a licence was in progress and paid $57,500 anyway. And the exposure is not confined to the unlicensed trader: Kim v. TWA Construction, Inc. (2022) held that a licensed general contractor cannot recover compensation for work performed for it by an unlicensed subcontractor, which makes a subcontractor’s paperwork the general contractor’s problem too.

How a licensed contractor ends up unlicensed

The stereotype is a trader who never held a licence. The expensive cases are mostly people who did. Three mechanisms account for most of them in California, and each is silent while it is happening.

• Workers’ compensation. Section 7125.2 suspends the licence by operation of law where required coverage is not obtained or maintained, effective on the date coverage lapsed or became required, whichever is first. The registrar’s notice follows later, so the suspension is already retroactive by the time anyone hears of it.
• Expiry. A licence not renewed stops being active on its expiry date, mid-job or not. Section 7141.5 lets the registrar renew retroactively only where a completed renewal application and the renewal plus delinquency fees are delivered or postmarked within 90 days of expiry.
• The name on the contract. A licence belongs to a particular legal person. Signing as a newly formed company, or under a qualifying individual who is not genuinely running the work, can mean the entity performing the contract is not the entity holding the licence.

Checking a licence properly takes four minutes

Every state that licenses contractors publishes a free lookup — in California the CSLB’s Check a License service, elsewhere the state board or the city agency that issues the licence. Do it twice: before signing, and before the final payment on any job that has run for months. Section 7031(a) asks about every day of performance, not the day you met.

What the record shows is mostly the apparatus that vanishes when a licence does. A California licensee files a $25,000 bond — raised from $15,000 on 1 January 2023 by Senate Bill 607 — which § 7071.6 holds for consumers damaged by a violation of the licence law and for employees owed wages. It is not project insurance: it is one fixed sum behind the licence, not an allowance per customer. Its real use is diagnostic, because an unlicensed contractor has no bond, no workers’ compensation recorded against a licence and no board able to order restitution, so the mechanics lien route and the complaint route close together.

What each side should actually do

For the customer, the licence check is the decision, not the payment. Withholding creates no right to money back where the state gives none — outside California the leverage is the defence you would run if you were sued, and it is strongest before the balance leaves your account, stated in a demand letter that names the section it rests on. In California the position reverses, but on a timer that starts the day the contractor stopped work, so a dispute allowed to drift can outlive the remedy. A job simply walked away from is a separate problem with separate deadlines.

For the contractor who has just found a gap, the calendar is the whole defence. Retroactive renewal is 90 days from expiry, and substantial compliance turns on having acted promptly and in good faith once you knew — measured against what you did in the following week rather than what you intended. Reinstating cover, filing the renewal and telling the customer in writing on the same day is not an admission; it is the only version of these facts that has ever been excused. None of which tracks whether anyone behaved badly: the bar lands on the contractor whose broker missed a renewal exactly as it lands on the one who never applied, which is the argument for treating a licence as a condition of getting paid rather than a credential to show clients.
