Verify a California Contractor License Before Hiring
A license number on a truck doesn't tell you whether a contractor can legally handle your project. Checking a California contractor license through the Contractors State License Board (CSLB) helps you catch inactive status, mismatched business names, and missing coverage before money changes hands.
Start with the official license record, then match it to the contractor, the work, and the contract. If you're hiring subcontractors, the same steps help protect your business.
Key Takeaways
License verification should answer three practical questions:
- Does the license belong to the person or business you're hiring, and is it active?
- Does the listed classification cover the proposed work?
- Are the required bond and workers' compensation filings current, and are any disciplinary actions listed?
An active license confirms licensing status. It doesn't guarantee workmanship, financial stability, or complete insurance protection. Keep references, project details, and insurance documents separate from your license review.
Know When Licensing Is Required
California generally requires a contractor license when the combined project cost reaches $1,000, including labor and materials. The old $500 threshold changed on January 1, 2025, under AB 2622.
The small-job exemption is narrow. Work below $1,000 qualifies only when no permit is required and the unlicensed person doesn't employ anyone on the project.
A permit requirement or even one hired worker can trigger licensing below that dollar amount. Splitting a larger project into smaller contracts doesn't create an exemption.
The CSLB's 2026 license law reference includes the licensing rules and minor-work exemption.
For contractors hiring subs, apply the rule to the actual work arrangement. A low bid doesn't remove licensing requirements, and your own license doesn't automatically authorize another business to perform licensed work independently.
Search the California Contractor License Database
Use the official CSLB license lookup from the Contractors State License Board to verify a California contractor license. Don't rely on a directory, advertisement, or screenshot supplied by the contractor. The public record contains licensing information maintained by CSLB.
Follow these steps:
- Enter the contractor's license number when you have it. This gives you the most direct match.
- If you don't have a number, search by business name or personnel name.
- Open the matching record and check the business identity, status, classifications, bond, workers' compensation information, and any listed discipline.
Name searches can return several similar businesses. Compare the full name and address before choosing a result.
If nothing appears, try the legal business name rather than a shortened advertising name. An application number or salesperson registration isn't a contractor license.
Save the record with the date you reviewed it. That gives your project file a clear starting point.
Match the Business and Status
Confirm Who You're Hiring
Compare the CSLB business name, address, and listed personnel with the proposal and contract. The licensed entity should match the business taking responsibility for the work.
A corporation's license belongs to that corporation. It doesn't automatically cover a separate LLC, a different company, or an individual operating independently.
A salesperson or employee may represent the licensed business without personally holding its license. The important match is between the licensed contractor and your contracting party.
Ask for a corrected agreement when the names don't line up. Don't accept another company's license number as an explanation.
Read the Status Carefully
Look for active status, then review the expiration date and any restrictions or notices. Inactive, expired, suspended, and revoked licenses don't authorize ordinary contracting work requiring an active license.
A bond entry alone doesn't establish active status. Neither does a wallet card issued before a later suspension.
Recheck the live record before signing and before paying. For longer projects, repeat the review during the job, especially near renewal dates.
Keep those checks in your subcontractor file. They help document that you reviewed more than the number printed on a bid.
Match the Classification to the Work
General Building Has Limits
A Class B General Building license generally covers building projects involving at least two unrelated trades beyond framing and carpentry. The classification rules have separate allowances for framing and carpentry.
A general building license doesn't authorize every standalone specialty job. Single-trade contracts can require the appropriate specialty classification or a properly licensed subcontracting arrangement.
Compare the actual contract scope with the license classification shown in the CSLB record. A full remodel and a standalone electrical installation raise different licensing questions.
Specialty Work Needs the Right Authority
Specialty work requires the right license classification, even when a contractor holds a general building license. Common classifications include C-10 Electrical, C-36 Plumbing, and C-39 Roofing. Match the listed authority to the work promised in the contract.
If you're a prime contractor hiring subs, review each subcontractor's classification separately. Your general building license doesn't replace a subcontractor's required specialty license.
The contract should identify who will perform work outside the prime contractor's own classifications. Settle that before the crew arrives, not after a permit or payment dispute.
Review the Bond Information
An active contractor license generally requires a $25,000 bond, called a contractor license bond. That amount increased from $15,000 on January 1, 2023, under SB 607.
The contractor pays a premium to a surety company for the surety bond. They don't normally deposit the full $25,000.
Review the surety name, bond number, effective date, and any cancellation information shown in the license record. Additional entries may include a Bond of Qualifying Individual, a disciplinary bond, or an LLC employee/worker bond.
Our contractor license bond requirements explain when additional bonds apply.
A $25,000 license bond doesn't guarantee that every loss on your project will be paid. Claims must qualify under the bond and applicable law.
A license bond also differs from a project-specific performance bond. Contractors generally must reimburse the surety for valid claims it pays.
If a filing is missing or canceled, resolve it before relying on the license for new work.
Read Workers' Compensation Entries
The CSLB record may list workers' compensation insurance, self-insurance information, or an exemption. Review the carrier, policy details, and effective dates when listed.
Contractors with employees generally need workers' compensation coverage. Certain classifications require coverage even when the contractor has no employees, so an exemption isn't available to every business.
An exemption means the contractor has represented that it qualifies under the applicable rules. It isn't an insurance policy and doesn't cover injured workers.
If the contractor claims an exemption but brings employees to your project, ask for an explanation before work starts. Don't assume describing everyone as an independent contractor settles the issue.
The CSLB workers' compensation requirements explain the required filings.
For subcontractor onboarding, collect current coverage documentation separately. The license record supports your review, but it doesn't describe every policy term, exclusion, or contractual insurance requirement.
Keep the certificate with the subcontract agreement.
Review Disciplinary Actions
Read any disciplinary information, citations, or related notices on the record. An active license doesn't erase a contractor's disciplinary history.
Consider the conduct, dates, and outcome. A resolved administrative issue and repeated customer-related violations deserve different consideration.
CSLB's public information doesn't show every complaint or investigation. No listed discipline doesn't prove that nobody has complained or had a problem.
Contracting without required licensure is a misdemeanor under Business and Professions Code section 7028. An unlicensed contractor convicted for the first time can face a fine of up to $5,000, six months in county jail, or both. Administrative civil penalties can reach $15,000.
Section 7031 generally prevents an unlicensed contractor from suing to recover payment for work that requires a license. Limited statutory exceptions apply.
For contractors, keeping a license active protects their ability to take on future jobs, but it doesn't guarantee good work.
Keep Other Hiring Checks Separate
License verification answers licensing questions. References, insurance, permits, and contract terms answer different questions.
Ask references about similar work, change orders, communication, and completion. Photos can show finished results, but they don't establish who performed the work or whether the project stayed on budget.
Review liability insurance separately by collecting a general liability certificate and checking the named insured and coverage dates. Our contractor liability insurance guide explains the protection available for covered third-party injury and property damage claims.
A license bond doesn't replace general liability coverage, and general liability doesn't replace workers' compensation.
Your written agreement should identify the licensed business, scope, price, payment schedule, and responsibility for permits. Include how changes will be approved and priced.
For homeowners, California generally limits a home improvement down payment to $1,000 or 10% of the contract price, whichever is less. Limited exceptions apply.
For contractor-to-subcontractor agreements, use payment terms suited to that business relationship.
Understand What Licensing Requires
Eligibility and Experience
The qualifying individual must be at least 18 and have a valid Social Security number or Individual Taxpayer Identification Number (ITIN).
CSLB generally requires four years of experience within the previous 10 years, and the work must meet CSLB's qualifying rules. It must be at journey level or higher, including qualifying work as a foreman, supervising employee, contractor, or owner-builder.
Journey-level experience means the person can perform the trade without direct supervision. Time spent only as a helper doesn't meet that standard.
Experience documentation must describe relevant work and have a qualified person certify it. CSLB can request supporting records.
Application and Business Setup
Applicants choose a classification, document experience, submit the application and fee, complete fingerprinting, pass required exams, and provide the required bond and insurance filings before issuance.
Corporations and LLCs must register with the California Secretary of State. Applicable city or county business licenses are separate requirements.
CSLB's application forms and instructions include the experience certification and license verification forms.
Acknowledgment typically arrives within four to six weeks. The overall process often takes three to six months, depending on application corrections, background review, testing, and final filings.
A pending application doesn't authorize licensed contracting work.
Know What the Exams Cover
Most applicants must pass a Law and Business exam and a classification-specific trade exam. Both are closed-book and multiple-choice.
Exams generally contain roughly 100 to 120 questions, with up to 3.5 hours allowed. Question counts and content vary by examination.
The business and law portion covers business organization, financial management, employment, contracts, licensing, safety, and related legal responsibilities. Trade exams cover the classification's technical work, planning, estimating, installation practices, and safety.
Use the CSLB study guide for your classification. Spend extra time on topics you don't handle regularly, especially estimating, business rules, and code-based decisions.
New applicants also complete CSLB's separate asbestos open-book requirement before licensure.
California has limited reciprocity agreements with Arizona, Louisiana, Nevada, and North Carolina. Eligible applicants may receive a trade-exam waiver, generally after five years of qualifying licensure in a similar classification.
Reciprocity doesn't grant a California license or automatically waive that exam. Other examination waivers have separate eligibility rules.
Budget for Fees and Bonds
The application fee is $450 for an original, single-classification application. Initial issuance and renewal charges depend on the business structure.
These are the standard licensing fees and fingerprint processing charges:
| Expense | Sole owner | Corporation, LLC, or partnership |
|---|---|---|
| Application fee | $450 | $450 |
| Initial license fee | $200 | $350 |
| DOJ and FBI fingerprint processing | $49 | $49 per required person |
| Timely active renewal, every two years | $450 | $700 |
The initial license fee, combined with the $450 application charge, brings state fees to $650 for a sole owner and $800 for a non-sole owner.
CSLB fingerprinting instructions specify $32 for DOJ processing and $17 for FBI processing. The operator adds a rolling fee, so the total is often around $75 per person.
Our standard contractor license bond premiums range from $139 to $2,500 annually. The surety bond's premium is its annual price, not its face amount. Credit, business background, and bond history affect pricing.
Adding state fees, $49 fingerprint processing, and that bond range gives a sole-owner subtotal of $838 to $3,199.
For an LLC with one required fingerprint submission, the same subtotal is $988 to $3,349. That isn't the complete LLC cost. LLCs also need a $100,000 employee/worker bond and required liability coverage.
Rolling fees, testing charges, additional bonds, insurance, business registration, and study materials sit outside those subtotals.
Keep Your License Active
An active California contractor license renews every two years. Standard timely renewal costs $450 for sole owners and $700 for non-sole owners, as listed in CSLB's June 2026 board materials.
C-10 electrical contractors have an additional $20 renewal charge. Late renewals cost more.
License renewal, bond renewal, and insurance renewal can fall on different dates. Paying one doesn't automatically handle the others.
Set separate email, phone, and calendar reminders. Keep your address, business information, and qualifying individual information current with CSLB.
A bond cancellation or missing required insurance can lead to suspension even before the license expiration date. Replacing coverage isn't the same as confirming reinstated status.

Frequently Asked Questions
Can You Take the Exams Online?
No. CSLB qualifying examinations are taken in person at PSI testing locations. Applicants can schedule online after receiving their Notice to Schedule, but online scheduling isn't remote testing.
The separate asbestos open-book requirement is different from the closed-book qualifying examinations.
Plan your licensing schedule around the required testing appointments. Passing an exam still doesn't authorize contracting until CSLB issues the license and the required filings are complete.
Does a Business License Replace CSLB Licensing?
No. A city or county business license covers local business requirements. Secretary of State registration establishes a corporation or LLC's business registration.
Neither document authorizes work that requires a CSLB contractor license.
The same distinction applies to a home improvement salesperson registration. It identifies a registered salesperson, not a licensed contractor authorized to take responsibility for construction work.
Your contracting party still needs the appropriate active license and classification.
Check Before You Commit
Match the licensed business and classification to the project, then review the bond, workers' compensation entry, and any listed discipline.
Repeat the live California contractor license check before signing or paying. Keep the dated record with your contract and insurance documents.
For contractors hiring subcontractors, make this part of every onboarding review. A complete file helps you catch licensing problems before they interrupt your project.
