California C-10 Electrician License Requirements (2026)

California is one of the most heavily regulated electrical jurisdictions in the United States. Two distinct credentials are required to operate independently as an electrical professional: the Class C-10 Electrical Contractor license issued by the Contractors State License Board (CSLB), which authorizes the business to bid and perform electrical work valued at $500 or more, and the General Electrician Certification issued by the Department of Industrial Relations (DIR), which certifies the individual journeyman to perform the work. This guide covers the C-10 contractor license; the DIR certification is summarized in the dedicated section below.

Regulatory Body Profile

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

The Eligibility Audit

The applicant must be at least 18 years of age and possess a valid 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 Standards

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 (CSLB form 13A-11), signed under penalty of perjury by a qualified verifier
W-2 statements, pay stubs, and tax returns documenting the four-year period
DIR General Electrician Certification card (where applicable, accepted as direct proof of journeyman status)
Apprenticeship completion certificate from a state-approved electrical apprenticeship program

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.

The Exam Syllabus

The exam, administered by PSI Services LLC (under contract to CSLB), breaks into the parts shown below — all must be passed before licensure:

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

Examination fee: Bundled with the $450 application fee; no separate examination fee for the first sitting.

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.

Bonding, Insurance & Financial Security

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.

Schedule of Fees

Fee	Amount
Application (non-refundable)	$450
Initial license — sole owner	$200
Initial license — non-sole owner	$350
Renewal (every 2 years)	$450
Fingerprinting (DOJ + FBI)	$49

Renewal and Continuing Obligations

The California Class C-10 — Electrical Contractor runs on a 2 years renewal cycle. The current renewal fee is $450. Active sole-owner licenses renew every two years for $450. Non-sole-owner licenses renew for $700. Inactive licenses renew for $300 (sole) or $500 (non-sole). Renewal notices are mailed approximately 60 days before expiration. CSLB does not impose a continuing-education requirement, although the contractor is responsible for staying current on changes to the California Building Standards Code and the trade-specific code that governs the license classification.

Out-of-State Reciprocity

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

Reciprocal State	Accepted Exam	Conditions
Arizona	Trade exam waived	Active C-10 holder for 5 of past 7 years; same classification.
Nevada	Trade exam waived	Active C-10 holder for 5 of past 7 years; same classification; passes Nevada Law & Business.
Utah	Trade exam waived	Active C-10 holder for 5 of past 7 years; same classification; passes Utah Business & Law.

California does not accept the NASCLA Accredited Examination for the C-10 Electrical classification. Reciprocity is limited to bilateral CSLB agreements with Arizona, Nevada, and Utah.

The Application Roadmap

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.
Document four years of journeyman electrical experience. Complete the Certification of Work Experience and gather W-2s, pay stubs, and apprenticeship records that prove the four-year requirement.
File the Application for Original Contractor License. Submit Form 13A-1 with the $450 non-refundable application fee. Specify the C-10 classification.
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.
Pass both examinations. Both portions must be passed with a minimum score of 72%. The C-10 Trade exam covers the National Electrical Code (NEC), grounding and bonding, raceway and conductor sizing, motors and transformers, low-voltage systems, and solar PV.
Submit fingerprints (Live Scan or hard cards). Pay the $32 California Department of Justice processing fee and the $17 FBI processing fee.
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.
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.
Verify DIR electrician certification (qualifier). The qualifier and any employee performing electrical work must hold a separate General Electrician Certification issued by the California Department of Industrial Relations, requiring 8,000 hours of journeyman-level OJT and a written examination.
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.

Pre-Application Checklist

Ahead of submission to CSLB, confirm every item on this short list:

☐ Completed Application for Original Contractor License (Form 13A-1) — C-10 classification
☐ Certification of Work Experience (Form 13A-11) documenting four years of journeyman-level electrical work
☐ $25,000 contractor license surety bond filed on the CSLB-prescribed form
☐ Workers' Compensation Certificate of Insurance — or signed Exemption Certification
☐ Completed Asbestos Open-Book Examination booklet

Where Applications Stall

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).

Forgetting the DIR certification track

A surprising number of C-10 applicants pass the CSLB exam and post the bond, only to discover that they cannot legally perform any electrical work themselves until the separate DIR General Electrician Certification is obtained. Begin the DIR application in parallel with the CSLB application to avoid a multi-month gap.

Common Questions

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

Yes. The CSLB C-10 license authorizes the business to bid and perform electrical contracting work in California. The DIR General Electrician Certification certifies the individual to perform the physical electrical work and is required for every journeyman, foreman, and supervising electrician on the job. The two are obtained from different agencies and renewed separately.

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

The Department of Industrial Relations requires 8,000 hours of qualifying on-the-job electrical experience before a candidate may sit for the General Electrician Certification examination. Approved apprenticeship and classroom hours may count toward the total.

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 CCR Title 16 scope of the C-10 classification expressly includes "solar photovoltaic cells", and the Trade examination outline includes questions on PV system installation, grounding, conductor sizing, and inverter interconnection.

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

No. California does not accept the NASCLA Accredited Examination for the C-10 classification. The applicant must pass the CSLB-administered Law & Business and C-10 Trade examinations through PSI.
