California Carpentry License Requirements

California has two separate CSLB carpentry classifications. C-5 covers form work, framing and rough carpentry for framed structures and associated work such as subflooring, siding, exterior stairs and railings, overhead doors, roof decking, trusses, and sheathing. C-6 covers making, installing, erecting, and finishing cabinets, cases, sashes, doors, trims, nonbearing partitions, and other finish carpentry. A CSLB license is generally required unless the entire 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.

Regulatory Body

California Contractors State License Board (CSLB) administers the credential or scope-specific rules discussed here under California Business and Professions Code, Chapter 9 (Contractors). Whether that pathway applies depends on the work scope and conditions explained below. CSLB issues and regulates the C-5 and C-6 contractor classifications.

Official portal: https://www.cslb.ca.gov/

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.

Experience and Education

Plan to substantiate 4 years of Experience in the requested C-5 or C-6 class at journey level, or as a 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

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.

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
Requested C-5 or C-6 trade examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: The $450 original-application fee includes examination or waiver for one classification. CSLB lists $150 for each additional classification on an original application.

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; use CSLB rather than unsourced fixed score, timing, or retake-fee claims.

Insurance and Bonds

A contractor license surety bond of $25,000, on the CSLB's prescribed form, is a precondition to issuance.

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-5 or C-6-only general-liability minimum.

Workers' compensation

California employers must carry workers’ compensation coverage, including when they have one employee. A no-employees exemption is available only if CSLB’s conditions are met; C-5 and C-6 are not among the classifications currently barred from the exemption.

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.

Fee Schedule

Fee	Amount
Application	$450
Initial license — sole owner	$200
Initial license — non-sole owner	$350
Renewal (every 2 years)	$450
Recorded fingerprinting fee	$49

Renewal and Continuing Education

Renewal of the California Class C-5 Framing and Rough Carpentry / C-6 Cabinet, Millwork and Finish Carpentry comes due every 2 years. As cited, the renewal fee stands at $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 applicable workers’ compensation coverage.

Continuing education: CSLB’s current renewal and issuance pages do not list C-5 or C-6 continuing education. Check separate local or credential-specific requirements.

Reciprocity

The NASCLA Accredited Examination is not accepted by California for this classification.

Reciprocal State	Accepted Exam	Conditions
Arizona	Possible trade-exam waiver	CSLB maps Arizona C-7, K-7, K-61, or L-7 Carpentry to C-5; Arizona K-61 also maps to C-6. CSLB decides whether to grant reciprocity.
Nevada	Possible trade-exam waiver	CSLB maps Nevada C-3 or C-3a to C-5 and C-3b Finish Carpentry to C-6. 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.

Carpentry 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 Carpentry License Requirements — Arizona Carpentry Contractor (C-7, R-7, or CR-7)
Nevada Carpentry License Requirements — Nevada C-3 Carpentry, Maintenance and Minor Repairs Contractor License
Oregon Carpentry License Requirements — Oregon Construction Contractors Board License (Carpentry)

Step-by-Step Application Roadmap

Choose the correct classification. C-5 and C-6 have separate scopes; apply for each classification the business will perform.
Document four years of qualifying experience. Use CSLB’s application certification and retain supporting records.
File the original application. The application/examination or waiver fee is $450 for one classification; an additional classification on an original application is $150.
Pass the required examinations. Complete Law and Business plus the requested C-5 or C-6 trade exam unless CSLB grants a trade-exam waiver.
Finish CSLB issuance. After passing, submit the initial fee, $25,000 contractor bond, asbestos open-book examination, and the workers’ compensation, qualifying-individual, or LLC documents CSLB identifies.

Application Checklist

These are the pieces to lock down before filing with CSLB:

Correct C-5 and/or C-6 classification selected
Four years of qualifying experience and CSLB certification
$450 original application for one classification; $150 for an additional classification
Law and Business plus applicable trade examination unless CSLB grants a waiver
$25,000 contractor bond or approved alternative
Completed asbestos open-book examination
Workers’ compensation proof or a valid exemption
Initial fee: $200 sole owner or $350 non-sole owner

Common Filing Mistakes

Working from the cited board instructions, here are the snags most likely to trip up a California Carpentry filing.

Treating C-5 and C-6 as one classification

They have separate CSLB scopes; apply for each classification the business will perform.

Relying on the old $500 threshold

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

Claiming an automatic reciprocity waiver

CSLB decides whether to grant a trade-exam waiver and can still require the exam.

Frequently Asked Questions

What is the difference between C-5 and C-6?

C-5 is framing and rough carpentry for framed structures and associated work. C-6 is cabinets, millwork, and finish carpentry. They are distinct CSLB classifications.

Does a carpentry project 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 a no-employee C-5 or C-6 contractor use the workers’ compensation exemption?

Potentially, if all CSLB exemption conditions are met. C-5 and C-6 are not in CSLB’s current list of classifications prohibited from filing the exemption.

Can an Arizona or Nevada carpenter skip the California trade examination?

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