California Contractor License Requirements: the $1,000 Rule

Short answer: In California, construction licenses come from the Contractors State License Board (CSLB), and you need one once the total contract price — labor, materials, everything — reaches $1,000. Since January 1, 2025 the exemption below that figure carries two extra conditions: the job must need no building permit of any kind, and you must hire nobody to help. Advertising under $1,000 is allowed only if the ad says you are unlicensed.

Every construction license in the state is issued by the Contractors State License Board, a board inside California’s Department of Consumer Affairs. CSLB decides who gets a license, which classification it covers, and what happens to people who take work without one. Taxes are a separate question with separate agencies — the IRS federally, and the California Department of Tax and Fee Administration for the sales tax that attaches to materials and fixtures, which California sales tax for contractors handles on its own page. What follows is only about the license.

Which jobs need a CSLB license in California?

The trigger is the aggregate contract price: labor, materials, and every other item added together, not the labor portion alone.

Your situation	License required?
Total price under $1,000, no permit needed, no one helping you	No
Total price $1,000 or more	Yes
Any price, but the work needs a building permit	Yes
Any price, but you hire someone to assist or perform the work	Yes
You hold yourself out as licensed or qualified to contract	Yes

Two of those rows are new. Before 2025 the small-operations exemption in Business and Professions Code section 7048 turned on the dollar figure alone. It now turns on three things at once, and failing any one of them puts you back inside the licensing requirement even on a $400 job.

The exemption also cannot be manufactured. Minor work that is part of a larger project does not qualify, and a job cannot be broken into sub-$1,000 slices to stay under the line.

Why does CSLB’s own website still say $500?

Because parts of it have not caught up. Assembly Bill 2622 (Chapter 240, Statutes of 2024) rewrote Business and Professions Code section 7048 effective January 1, 2025, raising the threshold from $500 to $1,000. But CSLB’s own Building Officials guide still asks “to be performed is under $500?” and still tells building officials the exemption covers work “less than $500” — and a great deal of third-party California contracting advice was written against the old number.

Read the change carefully before treating it as good news. The figure doubled, but the conditions attached to it did not exist before. A one-person operator doing $900 of permit-free work is fine; the same operator bringing a helper for the afternoon is not, and was not caught by the old rule. For most working contractors the exemption got narrower, not wider.

Which license classification do you apply for?

CSLB does not issue one general license. You apply in the classification that matches the work:

• Class A — General Engineering Contractor, for fixed works requiring specialized engineering knowledge.
• Class B — General Building Contractor, for structures involving at least two unrelated trades.
• Class B-2 — Residential Remodeling Contractor, a separate classification for remodel work on existing homes.
• Class C — Specialty Contractor, covering 43 trade classifications running from C-2 Insulation and Acoustical through C-60 Welding and ending with C-61 Limited Specialty.

CSLB also issues two certifications that sit on top of an existing license rather than replacing it: Asbestos (ASB) and Hazardous Substance Removal (HAZ). You can hold more than one classification, but each one you add has to be earned on its own.

What does CSLB require before it issues the license?

The application is not a formality. You must be at least 18, and the qualifier must show at least four full years of journey-level experience in the classification applied for, earned within the previous ten years, as a journeyperson, foreperson, supervising employee, or contractor. CSLB’s own wording matters here: credit is given only for experience at those levels, so years spent as a trainee or apprentice do not count. Every applicant also completes an asbestos open book exam before licensure.

Then there is the bond. Senate Bill 607 raised the contractor’s bond to $25,000 effective January 1, 2023, and CSLB will not issue, reactivate, or renew an active license without it (a $25,000 cashier’s check filed with the board is the alternative). A Bond of Qualifying Individual, also $25,000, is required when the license is qualified by a Responsible Managing Employee or by certain Responsible Managing Officers rather than by the owner. A disciplinary bond applies only after a revocation, at a minimum of $25,000 and a maximum of ten times the license bond. Whether you license as an individual, a corporation, or an LLC changes bonding and personal exposure — do I need an LLC to freelance covers that trade-off.

Do you need workers’ compensation if you work alone?

For now, usually you can certify out of it — but that door is scheduled to close. Under Business and Professions Code section 7125 a licensee with no employees may file a signed exemption with CSLB instead of a certificate of insurance.

There is a hard exception, and it is classification-based rather than headcount-based. Section 7125 withholds the exemption from anyone holding an active C-8 Concrete, C-20 Warm-Air Heating/Ventilating and Air-Conditioning, C-22 Asbestos Abatement, C-39 Roofing, or D-49 Tree Service (a subcategory of C-61) license. Those licensees must carry workers’ compensation insurance or a Certification of Self-Insurance whether or not they have employees. A solo roofer in California cannot file the exemption at all.

Then the exemption disappears for everyone else. A replacement version of section 7125 becomes operative on January 1, 2028, and it removes the no-employees exemption entirely, leaving only a carve-out for joint ventures without employees. Watch that date rather than banking on it — Senate Bill 216 originally set it at January 1, 2026 before Senate Bill 1455 pushed it to 2028, so it has already moved once.

Do not read today’s exemption as a grace period for hiring, either. Coverage must be in force before you employ anyone. Filing an exemption and then putting someone on the job is cause for discipline carrying a minimum civil penalty of $10,000 for a sole owner and $20,000 for a partnership, corporation, or LLC. The 90-day figure that circulates is a narrower rule than people think: if CSLB receives your certificate within 90 days of the date the coverage actually took effect, the registrar backdates the filing to that date. Coverage limits and the general liability side are covered in California contractor insurance requirements.

What happens if you work without a license?

Contracting without a license is a misdemeanor in California. A first conviction carries up to six months in county jail, a fine of up to $5,000, or both. A second conviction carries a fine of 20 percent of the contract price or of the payments made to the unlicensed person, or $5,000, whichever is greater, plus at least 90 days in county jail unless the court states on the record why the interests of justice call for less.

The administrative track runs alongside the criminal one and is the one most unlicensed operators actually meet. CSLB’s registrar issues a citation with an order of abatement and a civil penalty, and that penalty range changed recently: since July 1, 2026 it runs from $1,500 to $15,000, up from the $200 floor that older guides still quote. Using a contractor’s license number that is not yours, with intent to defraud, is punished separately again — up to $10,000 and imprisonment in state prison or county jail for up to a year, which is what puts felony exposure on the table.

The civil consequence is often the one that ends the business. An unlicensed person has no standing to collect: consumers are not legally required to pay someone who is not state-licensed, and cannot be sued for non-payment. You can complete a $40,000 job, invoice it correctly, and have no way to enforce the debt.

Owner-builders have a narrow lane of their own. A property owner who contracts directly with licensees for each trade may have no more than four single-family residential structures intended or offered for sale in a calendar year — a cap that does not apply at all if the owner contracts with a general contractor for the construction. Selling five or more structures within a year of completion is conclusive proof the owner built them for sale.

How does a homeowner check your California license?

Through CSLB’s own Check a License tool, which the board also points people to from CheckTheLicenseFirst.com. A client can search by license number, by business name, or by your personal name, and CSLB is explicit that the record includes complaint disclosure — so a homeowner who only has the name on your van can still find you.

Expect that search to happen before the callback, not after. Put the license number on the estimate and the invoice rather than waiting to be asked, and make sure the classification on file actually covers what you are quoting.

What do you have to keep once the license is in your name?

Licensing is the entry ticket; the ongoing burden is documentary. You need to show what a job was contracted for, what you charged, and what you paid in materials — and you need it legible when a bond claim, an audit, or a CSLB complaint arrives years later.

That is a record-keeping problem, not a licensing one. Keel is an iOS app that keeps those records entirely on the device — no account, no bank connection, no cloud sync, and an App Store privacy label that reads Data Not Collected. It produces invoice PDFs with your own numbering, your logo, and a payment-link QR code; captures receipts read on-device with Apple Intelligence; logs mileage; and writes everything into an append-only, hash-chained ledger you can export as one file per year, or as an Accountant Pack. The free tier is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase.

Keel does not apply for your CSLB license, file your taxes, or sell you a bond. It keeps the paper trail those things depend on. If your receipts are still in a truck console, a contractor receipt organizer is the place to start.

Frequently asked questions

Is the California contractor license threshold $500 or $1,000?

It is $1,000, effective January 1, 2025 under AB 2622, which rewrote Business and Professions Code section 7048. The old $500 figure is still printed in CSLB’s own Building Officials guide and in a great deal of secondary advice written before the change. Use $1,000, but remember the exemption below it now also requires that no building permit is needed and that you employ no one on the job.

Can I do a $900 job in California without a license?

Only if all three conditions hold: the total price of labor, materials, and everything else stays under $1,000, the work requires no building permit of any kind, and you do the work alone without hiring anyone to assist. If you advertise for that work, the advertisement must state that you are not licensed.

Does California have one general contractor license?

No. CSLB issues Class A General Engineering, Class B General Building, Class B-2 Residential Remodeling, and 43 Class C specialty classifications running from C-2 to C-61. Asbestos and Hazardous Substance Removal certifications sit on top of a license rather than replacing one. You are licensed for the classifications you qualified in, and working outside them is treated as unlicensed work in that trade.

Do I need workers’ compensation as a solo contractor in California?

Today, usually yes — you file a CSLB exemption certifying you have no employees. But active C-8, C-20, C-22, C-39, and D-49 licensees must carry coverage or self-insurance regardless of headcount, and the no-employees exemption is scheduled to disappear for everyone when a replacement version of section 7125 becomes operative on January 1, 2028. Coverage must be in force before you employ anyone, not afterwards.

How much experience does CSLB require?

At least four full years of journey-level experience in the classification applied for, earned within the previous ten years, as a journeyperson, foreperson, supervising employee, or contractor. Time as a trainee or apprentice earns no credit. Applicants must also be at least 18 and complete the asbestos open book exam before the license issues.

Can an unlicensed contractor sue a California client for unpaid work?

No. Consumers are not legally required to pay a person who is not state-licensed and cannot be sued for non-payment. This applies to the whole contract, not just the portion over the threshold, which is why the exemption conditions matter more than they look.
