When a CSLB license is required

the project requires a building permit
the work uses employee labor
the combined labor-and-material cost is $1,000 or more

Requirements

Experience: CSLB requires at least 4 years of journey-level or equivalent experience within the last 10 years for the qualifying individual
Examinations: Applicants must pass the Law and Business exam and the Class B trade exam unless CSLB grants a waiver
Original application fee: CSLB's current fee schedule lists $450 for the original application for one classification

Bond: An active contractor license bond of $25,000 is required before CSLB will issue the license
Fingerprints: Live Scan fingerprinting is part of the application process
Workers' compensation: Proof of workers' compensation coverage is required unless the business qualifies to file an exemption because it has no employees

Scope of Work

A Class B general building contractor may take a prime contract or subcontract for framing or carpentry projects, and for projects that require two or more unrelated building trades or crafts. If the job involves only a single specialty trade, the work generally belongs to the appropriately licensed specialty contractor unless the Class B contractor also holds that specialty classification or another CSLB exception applies.

Compliance Risk

California treats unlicensed contracting as a serious enforcement issue. CSLB says first-time unlicensed contracting offenses are usually misdemeanors that can bring up to six months in jail, a $500 criminal fine, and an administrative fine of $200 to $15,000.
