A California electrician license lookup takes two searches, not one. The Contractors State License Board (CSLB) licenses the business that contracts for electrical work, and the Department of Industrial Relations (DIR) certifies the individual worker who actually handles the wiring. Both databases are free and public. Running one without the other leaves a real gap, because a company can hold a valid C-10 license while sending an uncertified worker to your house, and a certified electrician can be employed by an unlicensed outfit.
The two lookup pages:
- CSLB contractor search: cslb.ca.gov/onlineservices/checklicenseII/checklicense.aspx
- DIR electrician certification search: dir.ca.gov/dlse/ecu/ElectCert/electcertsearch.asp
Why Two Databases
California regulates the business and the worker separately. The contracting business needs a C-10 Electrical Contractor classification from the CSLB to bid, sign contracts, and oversee projects.1Contractors State License Board. Licensing Classifications Detail – C-10 Electrical Contractor The individual electrician needs a separate certification from the DIR showing they passed the state’s competency exam.2California Legislative Information. California Labor Code 108.2 Check both before signing anything.
How to Search the CSLB Contractor License
The fastest search is by license number. California law requires that number to appear on every advertisement, contract, and bid, so any written communication from the contractor should have it. If you don’t have the number, search by the exact business name or the name of the owner or qualifier on the license.
Once the record loads, confirm four things:
- Classification includes C-10 Electrical. Some contractors hold several classifications, but C-10 has to be one of them for electrical work.
- Status reads “Active.” Any other designation means the business cannot legally contract for electrical work that costs $1,000 or more, requires a permit, or involves hired labor.3Contractors State License Board. CSLB Industry Bulletin 24-07 – License Requirement for Minor Work Increases from $500 to $1,000
- Workers’ compensation is current. A contractor with employees must show an active policy. A solo operator can file an exemption instead. If a company arrives with a crew but claims an exemption, ask about it.4Contractors State License Board. Workers’ Compensation Requirements
- Contractor’s bond is current. Every licensed contractor must carry a $25,000 surety bond that protects consumers from financial harm caused by defective work or license law violations.5Contractors State License Board. Bond Requirements
The $25,000 bond is not general liability insurance. The bond covers you if the contractor takes your deposit and disappears or does work that violates license law. Liability insurance covers property damage or injury during the job. California doesn’t require liability insurance as a licensing condition, so ask for proof of it separately.
How to Search the DIR Electrician Certification
You can search the DIR database two ways. The quickest is the six-digit number from the electrician’s certification card. A card number like E923456F is entered as 923456.6Department of Industrial Relations. Electrician Certification Search Without the card number, use the name-with-number search: the first four letters of the electrician’s last name plus the last four digits of their driver’s license or ID.
Results return one of several status labels:7Department of Industrial Relations. DLSE Electrician Certification Search – Status Explanations
- Certified (electrician). Passed the state exam and currently certified. This is the only status that allows independent electrical work under a C-10 contractor.
- Pending (electrician). Application met exam requirements, but the exam hasn’t been taken. Any expiration date shown is the deadline to sit for it.
- Not Certified (electrician). Certification expired, was suspended, or was revoked. Cannot legally perform electrical work.
- Active (trainee). Registered as an electrician trainee meeting training requirements. Trainees work under supervision, not independently.
- Inactive (trainee). Trainee registration expired, or the person withdrew from or didn’t enroll in required classes.
If an electrician arrives without a certification card, or the number returns anything other than “Certified,” you can stop work until the contractor sends someone properly certified.
Checking Disciplinary History on the CSLB Record
Scroll past the status line at the top of the CSLB record. The full record lists public disciplinary actions, citations, accusations, arbitration cases, and legal judgments. A contractor can carry an “Active” license and still have a history of consumer complaints or code violations.
Watch for a disciplinary bond, which is separate from the standard $25,000 contractor’s bond. The CSLB requires a disciplinary bond when a previously revoked license is reinstated, in an amount set by the Registrar based on the seriousness of the violation, with a $25,000 floor and a $250,000 ceiling.8California Legislative Information. California Business and Professions Code 7071.8 Its presence doesn’t automatically disqualify a contractor, but it tells you the business lost its license at some point for a license law violation. Read that alongside the rest of the record.
When a License Isn’t Required
Small jobs are the common exception, and the threshold changed recently. As of January 1, 2025, the licensing exemption applies only when the project costs under $1,000 in combined labor and materials, doesn’t require any type of building permit, and doesn’t involve any hired workers.9California Contractors State License Board. Before Applying for a License When No Exam is Required The old threshold was $500, and the outdated number still appears online.
Most residential electrical work needs a permit, which cancels the exemption regardless of cost. Swapping a breaker panel or adding a circuit typically triggers a permit under the California Electrical Code. If the job needs a permit or the person doing it has employees helping, a license is required no matter what the price tag says.3Contractors State License Board.

What to Do If the Lookup Shows a Problem
Your options depend on where you are in the project.
Before hiring. Walk away. A contractor who claims a license they don’t have is already misrepresenting themselves.
After hiring, before paying. California law does not require you to pay an unlicensed person for contracting work, and an unlicensed contractor cannot sue you for non-payment.10Contractors State License Board. Consequences of Contracting Without a License The protection is strongest when you verify the license before significant work is done.
Filing a complaint. The CSLB accepts complaints against both licensed and unlicensed contractors for up to four years from the date of the violation. File online at cslb.ca.gov or submit a paper form.11Contractors State License Board. Filing a Construction Complaint Separate forms exist for active job-site complaints, advertising violations, building permit violations, and solar work, so choose the one matching your situation.
Ask for two numbers before signing: the contractor’s CSLB license number and the electrician’s DIR certification card number. Any legitimate professional hands them over on request, and both searches take about two minutes each.
