CSLB Requirements for California Contractors
The Contractors State License Board sets the same core rules for every classification, then layers on entity-specific requirements for sole proprietors, partnerships, corporations, and LLCs. Miss one and CSLB will hold your file or issue a deficiency notice. Here's the current requirement stack in the order CSLB verifies it.
Age and identification
18 or older, valid Social Security or ITIN. CSLB cross-checks names against the state's disciplinary and small-claims databases.
Experience (four years)
Journey-level, foreman, supervising, or contractor-level work in the exact classification you apply for, performed within the last ten years, signed off by a qualifier who can be reached for verification.
Qualifying Individual (QI)
Every license needs a QI — either the owner, a Responsible Managing Employee (RME), or a Responsible Managing Officer (RMO). The QI takes the trade exam and is personally responsible for supervising construction operations.
Both CSLB exams
Law & Business (shared) and the classification-specific trade exam. Each requires 72% to pass; both are administered by PSI at CSLB-designated testing centers.
$25,000 contractor bond
Filed with CSLB within 90 days of the issuance letter. LLCs add a $100,000 employee/worker bond.
Workers' compensation
Required if you have any employees. C-39 (roofing) contractors must carry workers' comp regardless of employee count.
LLC liability insurance
LLCs must carry $1,000,000 in liability insurance, plus an additional $100,000 per licensed person listed on the license, up to $5,000,000.
Live Scan fingerprints
Every person on the license — owner, QI, RMO/RME, all partners — must be Live Scanned so DOJ and FBI results route to CSLB.

Frequently asked
Do I need a license for every job?
Yes if the total project (labor + materials) is $500 or more. Below $500 you can work as a handyman without a license, but you must disclose that you're unlicensed in writing.
Can an out-of-state contractor apply?
Yes. If you hold an active license in AZ, NV, or UT for the same class, CSLB waives the trade exam under interstate reciprocity — you still take Law & Business.
What disqualifies an applicant?
Recent felony convictions (especially fraud, theft, or violence), unresolved contractor complaints, unpaid child support, or false statements on the application. Most cases require a Statement of Rehabilitation.
