California General Contractor License Requirements (2026)

The California Contractors State License Board (CSLB) regulates every general contractor performing work valued at $500 or more in labor and materials in the State of California. The applicant for a Class B — General Building Contractor license must satisfy a four-year journeyman-level experience requirement, pass a two-part qualifying examination administered by PSI Services, file a $25,000 surety bond, and submit fingerprints for a state and federal background check before the license is issued.

Governing Authority

Under California Business & Professions Code §7000 et seq. (Contractors State License Law), Contractors State License Board (CSLB) is the body that issues this license and enforces compliance with it. 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

At a minimum the applicant has to be 18 years old and supply 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 & Education Matrix

Plan to substantiate 4 years of journeyman, foreman, supervising employee, contractor, or owner-builder with hard records. Payroll, tax, project logs, and supervisor verification are what the board relies on when it reviews the claim.

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
Written sworn statements from employers, fellow employees, or clients

Education substitution

Up to three of the four years may be credited based on accredited technical training, apprenticeship, or post-secondary construction coursework. A four-year construction-management degree typically substitutes for three years of journeyman experience.

Examination Structure

The licensing examination is delivered by PSI Services LLC (under contract to CSLB). All of the following parts must be cleared prior to issuance:

Law and Business — 115 questions, 210 minutes, passing score 72%
Trade — General Building (B) — 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.

Insurance & Financial Security

Licensure is conditioned on filing a $25,000 contractor license surety bond with the CSLB.

General liability

No statutory minimum for the basic Class B license, 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 (notably C-39 Roofing and B Building when claiming workers) 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.

Application and License Fees

Application (non-refundable)	$450
Initial license — sole owner	$200
Initial license — non-sole owner	$350

Reciprocity and Endorsement

California does not accept the NASCLA Accredited Examination for this classification.

Reciprocal State	Accepted Exam	Conditions
Arizona	Trade exam waived	Active for 5 of past 7 years; same classification; Arizona has a parallel reciprocal agreement.
Nevada	Trade exam waived	Active for 5 of past 7 years; same classification; passes Nevada Law & Business.

Step-by-Step Application Roadmap

Form your business entity. Register the business with the California Secretary of State (corporation, LLC, or partnership). Sole owners may operate under their legal name without state-level registration.
Document four years of experience. Complete the Certification of Work Experience and gather W-2s, pay stubs, and contracts that prove the four-year journeyman-level requirement.
File the Application for Original Contractor License. Submit Form 13A-1 with the $450 non-refundable application fee. Include the Certification of Work Experience and any qualifier documentation.
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 Trade examinations.
Pass both examinations. Both the Law & Business and Trade portions must be passed with a minimum score of 72%. Each part is administered separately at a PSI test center.
Submit fingerprints (Live Scan or hard cards). Pay the $32 California Department of Justice processing fee and the $17 FBI processing fee. Out-of-state applicants use FD-258 fingerprint cards.
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.
Pay the initial license fee and receive your pocket card. Pay $200 (sole owner) or $350 (non-sole owner). Once all requirements are accepted, CSLB issues the license number and mails the wall certificate and pocket card.

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a California General Contractor application.

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 — e.g., "framed structural walls per IRC R602", "set and stripped concrete forms", "supervised a four-person framing crew" — and confirm the dates 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 C-39 Roofing licensees and several other classifications 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 or to gather a missing W-2 frequently let the clock expire and have to refile from scratch (forfeiting the $450 application fee).

Study and Reference Materials

These are the preparation and reference materials tied to this credential — cited by the regulator or widely used by applicants. CLR earns nothing from listing them.
