California Electrician License Requirements (2026)

The Class C-10 Electrical Contractor license, issued by the Contractors State License Board (CSLB), authorizes a contractor to place, install, erect, or connect electrical wires, fixtures, equipment, raceways, conduits, and solar photovoltaic cells. California generally requires a contractor license when a project needs a permit, uses employee labor, or totals $1,000 or more. This guide covers the C-10 business license. California separately regulates persons performing electrician work for a C-10 contractor: the C-10 licensee is not required to hold DIR electrician certification merely by holding the license, but covered employees generally must be certified, registered apprentices, or eligible electrician trainees.

Regulatory Body

Authority over this credential rests with Contractors State License Board (CSLB), which issues and polices it under California Business & Professions Code §7000 et seq. (Contractors State License Law). The CSLB licenses and regulates contractors in 44 license classifications, investigates consumer complaints, enforces contractor license law, and prosecutes unlicensed activity through administrative, civil, and criminal action.

• Address: 9821 Business Park Drive, Sacramento, CA 95827 (mailing: P.O. Box 26000, Sacramento, CA 95826)
• Phone: (800) 321-CSLB (2752) — in California; (916) 255-3900 — outside California

Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number or Individual Taxpayer Identification Number (ITIN). No California residency requirement. Out-of-state applicants may apply.

Good moral character

Applicants must disclose any prior criminal conviction. CSLB conducts a criminal background investigation under Cal. B&P Code §480 and may deny licensure for offenses substantially related to the qualifications, functions, or duties of a contractor.

Background investigation

Mandatory fingerprinting through Live Scan (in-state) or hard cards (out-of-state). Results are reviewed by both the California Department of Justice and the Federal Bureau of Investigation.

Disqualifying conditions

• Felony convictions substantially related to construction or financial responsibility
• Prior license revocation in California or any other jurisdiction
• Outstanding court-ordered restitution to a contractor or homeowner

Experience and Education

The experience bar is 4 years of journeyman electrician, foreman, supervising employee, or contractor, and it must be backed by verifiable records — typically payroll, tax, project, or supervisor documentation covering the claimed period.

Accepted proof of experience or eligibility

• Certification of Work Experience in the current Application for Original Contractor License, completed by a qualified person with firsthand knowledge
• Payroll records or similar supporting documentation if requested by CSLB
• Official transcripts or apprenticeship-completion documentation when claiming education or training credit

Education substitution

Up to three of the four years may be credited from accredited technical training, an approved electrical apprenticeship, or post-secondary electrical coursework.

Exam Requirements

Testing provider or authority: PSI Services LLC (under contract to CSLB). The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

• Law and Business — 115 questions, 210 minutes, passing score 72%
• Trade — Electrical (C-10) — 115 questions, 210 minutes, passing score 72%

Examination fee: After CSLB accepts and refers the application for testing, PSI collects a separate fee for each examination. Confirm the current PSI fee when scheduling.

Retake policy: Applicants who fail an examination may reschedule for a fee. The application remains valid for 18 months from the date of acceptance, after which the applicant must reapply.

Insurance and Bonds

The applicant must secure and file a $25,000 surety bond before the CSLB will release the license.

General liability

No statutory minimum for sole proprietors and corporations, but commercial general liability is required for limited liability company (LLC) licensees in the amount of $1,000,000 per occurrence (and an aggregate policy limit increased by $100,000 for each additional employee, up to a maximum of $5,000,000).

Workers' compensation

Workers' compensation insurance is mandatory for any licensee with one or more employees. Sole-owner licensees with no employees may file a Workers' Compensation Exemption Certification; certain license classifications cannot claim exemption.

Additional financial requirements

LLC applicants must additionally maintain an LLC employee/worker bond of $100,000 to protect employee wages and fringe benefits.

Renewal and Continuing Education

The California Class C-10 — Electrical Contractor runs on a 2 years renewal cycle. The current renewal fee is $470. C-10 active timely renewal is $470 for a sole owner and $720 for a non-sole owner. CSLB does not impose a general continuing-education requirement for contractor-license renewal; separate DIR certification renewal requirements apply to certified electricians.

Reciprocity

For this classification, California does not recognize the NASCLA Accredited Examination.

California does not accept NASCLA for the C-10 classification; the NASCLA waiver is limited to B-General Building. CSLB reciprocity applies only to listed equivalent classifications in Arizona, Louisiana, Mississippi, Nevada, or North Carolina, and CSLB retains discretion to require the trade examination.

Electrician Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare California's requirements against the bordering jurisdictions before committing to an application:

• Arizona Electrician License Requirements — Arizona Electrical Contractor (C-11, R-11, or CR-11)
• Nevada Electrician License Requirements — Nevada C-2 Electrical Contractor
• Oregon Electrician License Requirements — Oregon General Journeyman Electrician (J) License

Step-by-Step Application Roadmap

1. Form your business entity. Register the business with the California Secretary of State if operating as a corporation, LLC, or partnership. Sole owners may operate under their legal name.
2. Document four years of qualifying electrical experience. Document four years within the prior 10 years at journey level or as a foreman, supervising employee, or contractor. A qualified person with firsthand knowledge must certify the experience; education or apprenticeship credit may cover up to three years.
3. File the Application for Original Contractor License. Submit Form 13A-1 with the $450 non-refundable application fee. Specify the C-10 classification.
4. Receive the Notice to Appear for Examination. After CSLB accepts the application, PSI mails a Notice to Appear with scheduling instructions for both the Law & Business and the C-10 Trade examinations.
5. Pass both examinations. CSLB requires the Law and Business and C-10 trade examinations unless a waiver applies. Each computer-based examination is 3½ hours; the official C-10 guide covers planning and estimating, rough wiring, finish wiring and trim, startup/troubleshooting/maintenance, and safety.
6. Submit fingerprints (Live Scan or hard cards). Pay the $32 California Department of Justice processing fee and the $17 FBI processing fee.
7. File the contractor bond and proof of insurance. File the $25,000 contractor surety bond, the workers' compensation certificate (or exemption), and (for LLCs) the $1,000,000 commercial general liability policy and $100,000 employee/worker bond.
8. Complete the Asbestos Open-Book Examination. Submit the completed asbestos open-book examination, included in the bond and fee letter sent by the CSLB Issuance Unit.
9. Meet DIR electrician-workforce rules. A C-10 licensee is not required to hold DIR electrician certification just because they hold the C-10 license. Employees performing covered electrician work must meet DIR certification, registered-apprentice, or electrician-trainee requirements. The General Electrician route requires 8,000 qualifying hours and an examination; DIR also recognizes other electrician classifications.
10. Pay the initial license fee and receive your pocket card. Pay $200 (sole owner) or $350 (non-sole owner). CSLB issues the C-10 license number, wall certificate, and pocket card.

Application Checklist

Common Filing Mistakes

The errors below are the ones that most frequently cost California Electrician applicants time, drawn from the cited board guidance.

Vague experience verification

A common reason CSLB returns the Certification of Work Experience is generic phrasing such as "helped out on jobsites" or "assisted the foreman". The verifier must use specific journeyman-level trade terminology, and the dates must match the applicant's W-2 record.

Bond and license number mismatch

The business name and license number on the contractor's bond must correspond exactly to the CSLB record. Even a missing "Inc." or a transposed digit will cause CSLB to reject the bond and delay issuance until a corrected rider is filed by the surety.

Missing the asbestos open-book exam

Many applicants assume the bond and fee letter only requires the bond and the initial fee. The completed Asbestos Open-Book Examination is required in the same envelope. Forgetting it sends the application back to the bottom of the Issuance Unit queue.

Workers' compensation exemption errors

Sole owners with no employees may file an exemption, but certain classifications (notably C-39 Roofing) cannot. Filing an exemption when not eligible voids the entire issuance package.

Letting the application time out

Once CSLB accepts the application, the applicant has 18 months to pass both examinations and submit all post-exam documentation. Applicants who pause to re-take the exam multiple times frequently let the clock expire and have to refile from scratch (forfeiting the $450 application fee).

Misapplying DIR certification rules

A C-10 licensee does not need DIR certification simply to hold the contractor license, but workers performing covered electrician work generally must meet DIR certification, apprenticeship, or trainee rules. Verify each worker’s role and status before assigning electrical work.

Study and Reference Materials

These materials are drawn from the regulator's own citations and the references applicants commonly use to prepare. CLR receives no compensation for listing them.

• C-10 Electrical Study Guide (free PDF) — CSLB. Official outline of the C-10 subject areas, weighting, sample questions, and suggested study resources.
• California Electrical Code and National Electrical Code — California Building Standards Commission / NFPA. Useful preparation resources for the C-10 topics; the CSLB C-10 examination itself is closed book.
• CSLB Law and Business study materials — CSLB. Use CSLB’s official Law and Business materials and examination guidance rather than a commercial provider’s claimed outline.

Frequently Asked Questions

Do I need both the CSLB C-10 and the DIR electrician certification?

The C-10 is the contractor-business license; DIR certification is a separate workforce rule. A person who simply holds a C-10 license is not required to be DIR certified, but covered employees performing electrician work for a C-10 contractor generally must be certified, registered apprentices, or electrician trainees who meet DIR requirements. A C-10 licensee employed under another C-10 contractor’s license must be certified.

How many hours of experience does DIR require for general electrician certification?

The General Electrician certification route requires 8,000 hours of qualifying work for an electrical contractor on NEC-covered systems, across at least two listed work areas. An electrician trainee who completes an approved curriculum may be eligible to take the exam before all hours are complete, but DIR does not issue the certification card until the experience requirement is met.

What surety bond does a C-10 electrician need to post?

A $25,000 contractor license bond is required, the same statewide CSLB bond amount in effect since January 1, 2023 under Senate Bill 607 and Cal. B&P Code §7071.6.

Does the C-10 trade exam cover solar PV?

Yes. The C-10 classification expressly includes solar photovoltaic cells. The current C-10 study guide also includes photovoltaic planning, rough wiring, finish wiring, and system-performance topics.

Can a NASCLA exam pass be used in lieu of the CSLB C-10 trade exam?

No. CSLB’s NASCLA Commercial General Builders waiver is limited to the B-General Building classification. C-10 applicants must meet the usual California examination requirements unless an applicable CSLB waiver or reciprocity determination applies.
