Quick Answer
Verify any California contractor's license at the official CSLB License Lookup at cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx. Enter the license number or business name. The lookup shows license status, classifications, bond and WC status, and any disciplinary actions. Every California homeowner and GC should verify before signing a contract or letting a sub on site. Call (858) 925-9555.
What the Lookup Shows
- License number and entity name
- Classifications (A, B, or C-XX)
- Status: Active, Suspended, Expired
- Original issue date and expiration
- Bond carrier and bond status
- Workers' comp carrier and status
- Personal/business identifier (sole prop, corp, LLC)
- Disciplinary actions and complaints
How to Use It
For homeowners: always check before signing. An active license, current bond, and current WC are the three minimum confirmations.
For GCs: verify every sub before they step on your job site. Print or screenshot the lookup as part of your sub file.
For Asena clients: we can help review CSLB license and filing information when requested; confirm current status with CSLB.
Red Flags on a CSLB Record
- Status "Suspended" — they can't legally work
- Bond status "Cancelled" — suspension is imminent or already in effect
- WC status "Exempt" in 2026 — likely not compliant under SB 216
- Disciplinary actions or complaints — investigate before contracting
- License classification doesn't match the work they're doing
How to Read the Current CSLB Record Before Signing a Contract
A CSLB lookup is a starting point for checking a contractor’s public license record, not a substitute for a written contract review or proof of current insurance. Compare the license number and business name with the proposal, then review the classification, license status, bond information, workers’ compensation indication, and any public disciplinary or complaint information shown by CSLB.
- Match the identity. Confirm the legal business name, qualifier, license number, and classification align with the contractor you are hiring.
- Check the bond and workers’ compensation indicators. A record can change, and a lookup does not replace current certificates or policy documents.
- Ask for current documents. Request a certificate of insurance and bond information appropriate to the project, and verify additional-insured or waiver wording with the issuing broker or carrier.
- Use the official record. Recheck the record through CSLB’s official license lookup before relying on a status shown in an older article, directory, or screenshot.
Official reference: California Contractors State License Board — Check a License. Insurance availability and policy terms depend on the actual business, project, carrier, and underwriting.

Practical review steps for California contractors
Before relying on a contractor record, compare the license number, classification, business name, status, expiration date, bond information, workers’ compensation information, and disciplinary or citation details shown by the official lookup. A search result is a point-in-time record; retain the date checked and verify important details again when a contract, permit, or renewal depends on them.
Insurance evidence should be checked separately. A license lookup does not prove that a general liability policy, commercial auto policy, workers’ compensation policy, or project-specific endorsement responds to every loss. Ask for a current certificate and, when the contract requires it, have the requested wording reviewed by the broker. The policy, endorsements, exclusions, and effective dates control.
When a lookup raises a question
If the record shows an inactive status, a bond issue, a workers’ compensation gap, a classification mismatch, or a business-name difference, pause before treating the contractor as approved. Ask the contractor for an explanation and confirm the relevant information with CSLB or the contract administrator. Do not infer that a similar business name is the same licensee.
- Record the official URL and date of the search.
- Compare the legal business name with the contract and certificate.
- Confirm the classification matches the work being performed.
- Check expiration, bond, and workers’ compensation fields separately.
- Escalate unresolved discrepancies before work begins.
