California Concrete Contractor License Requirements (2026)

California’s Contractors State License Board (CSLB) issues Class C-8 for concrete contractors. C-8 forms, pours, places, finishes, and installs specified mass, pavement, flat, and other concrete work, and places and sets screeds for pavement or flatwork. The classification excludes contractors whose sole contracting business is plaster coatings or placing and erecting reinforcing steel or bars. A CSLB license is generally required unless the whole undertaking fits the narrow Business and Professions Code §7048 exemption: under $1,000, no building permit, no contractor advertising, no employees, and no larger or improperly split project.

Who Issues the California Concrete Contractor License?

California Contractors State License Board (CSLB) administers the credential or scope-specific rules for concrete work in California under California Business and Professions Code, Chapter 9 (Contractors), and whether they apply depends on the work scope and conditions explained below. CSLB issues and regulates the C-8 Concrete classification.

California Concrete Contractor License Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number or Individual Taxpayer Identification Number (ITIN). CSLB accepts applications from out-of-state applicants; use the current application instructions for identity and address information.

Good moral character

CSLB reviews the application before issuance and may send an application for formal investigation.

Background investigation

CSLB’s application instructions require fingerprinting when applicable. Its current schedule lists $32 DOJ processing, $17 FBI processing, and a Live Scan operator fee that varies by location.

How Much Experience Do You Need for a California Concrete Contractor License?

Experience in the C-8 class at journey level, or as a foreman, supervising employee, contractor, or owner-builder. Keep payroll, tax, project, or supervisor records for every period you claim; CSLB can ask for them when it reviews the application.

Accepted proof of experience or eligibility

Have a qualified person with firsthand knowledge complete the experience-certification section of the CSLB application.
Keep the supporting records CSLB may request; failure to provide requested documentation can result in return, voiding, or denial.
Owner-builders must submit a Construction Project Experience form for each project claimed.

Education substitution

CSLB may credit up to three years for qualifying training, apprenticeship, or education. At least one year must be practical experience, with the required supporting documentation.

California Concrete Contractor Exam Requirements

Testing provider or authority: CSLB examination program. 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 examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
C-8 Concrete trade examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: Included for one classification in the $450 original-application fee.

Retake policy: CSLB supplies the examination instructions and study guide with the Notice to Appear. It tells candidates the passing percentage at the test site, so rely on CSLB’s current notice for scoring, timing, and retake details.

California Concrete Contractor Insurance and Bond Requirements

CSLB requires a $25,000 license surety bond, on its prescribed form, before it issues the California concrete contractor license.

General liability

CSLB’s issuance requirements include LLC liability insurance when applicable. Confirm entity-specific requirements in the issuance letter; CSLB does not publish a C-8-only general-liability minimum.

Workers' compensation

C-8 is one of the classifications CSLB lists as unable to file a no-employees workers’ compensation exemption. A C-8 licensee must keep a current certificate of workers’ compensation insurance or self-insurance on file.

Additional financial requirements

Active licensees must keep the contractor bond current. CSLB may also require a $25,000 Bond of Qualifying Individual for an RME or certain RMOs.

California Concrete Contractor License Renewal and Continuing Education

The California concrete contractor license renews every 2 years. The renewal fee is $450. The initial license term is two years. Timely active renewal is $450 for a sole owner and $700 for a non-sole owner; maintain the active-license bond and workers’ compensation coverage.

Continuing education: CSLB’s current renewal and issuance pages do not list C-8 continuing education. Check separate local or credential-specific requirements.

Does California Accept Out-of-State Concrete Contractor Licenses?

California does not accept the NASCLA Accredited Examination for the California concrete contractor license.

Reciprocal State	Accepted Exam	Conditions
Arizona	Possible C-8 trade-exam waiver	CSLB maps Arizona C-9, K-9, or L-9 Concrete to C-8. CSLB decides whether to grant reciprocity.
Nevada	Possible C-8 trade-exam waiver	CSLB maps Nevada C-5 Concrete to C-8. CSLB decides whether to grant reciprocity.

If CSLB grants reciprocity, it may waive the trade portion but retains the right to require it. Law and Business remains required.

Common Filing Mistakes

These are the problems most likely to delay or derail a California Concrete Contractor application, drawn from the instructions of CSLB and the other sources cited on this page.

Treating C-8 as a reinforcing-steel classification

CSLB excludes contractors whose sole contracting business is placing and erecting steel or bars for reinforcement.

Trying to use a no-employees workers’ compensation exemption

CSLB specifically excludes C-8 from that exemption.

Relying on the old $500 threshold

The current statutory exemption is under $1,000 and has permit, advertising, employee, and anti-splitting conditions.

Frequently Asked Questions

What work does C-8 cover?

C-8 covers forming, pouring, placing, finishing, and installing specified concrete work, plus placing and setting screeds for pavement or flatwork. CSLB lists specific scope exclusions.

Can a C-8 contractor use a no-employees workers’ compensation exemption?

No. C-8 is among the classifications CSLB lists as unable to file the exemption; a certificate of workers’ compensation insurance or self-insurance is required.

Does a concrete job always require a CSLB license?

No. The §7048 exemption is narrow: the complete undertaking must be under $1,000, require no permit, involve no contractor advertising or employees, and not be a larger or split project.

Can Arizona or Nevada concrete licensees skip the California trade exam?

Only if CSLB grants reciprocity for a mapped classification. CSLB may still require the trade examination and requires Law and Business.
