What happens if my General Engineering Contractor (Class A) expires in California?

CSLB says California generally requires a contractor license when the project requires a permit, uses employee labor, or the combined contract value is $1,000 or more.

California General Engineering Contractor License (Class A)

California requires a Class A General Engineering Contractor license for heavy civil and infrastructure construction — roads, bridges, dams, pipelines, treatment works, and power generation facilities. CSLB issues the license, and any project with a combined labor-and-material value of $1,000 or more that falls within the Class A scope requires you to hold an active one.

You need this license at $1,000 in combined labor and materials

CSLB's threshold for when a contractor 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

Four years of engineering experience qualifies you; two exams and a bond close the application

Experience: at least 4 years of journey-level or equivalent general-engineering experience within the last 10 years for the qualifying individual
Examinations: pass the Law and Business exam and the Class A trade exam (CSLB may grant a waiver)
Application fee: $450 for one classification; initial license fee is $200 (sole owner) or $350 (non-sole owner) after exam approval
Bond: an active contractor license bond of $25,000 must be on file before CSLB issues the license
Fingerprints: Live Scan fingerprinting is required
Workers' compensation: a Certificate of Workers' Compensation Insurance or valid exemption filing must be on file at CSLB before issuance
Asbestos open-book exam: submit the completed verification form to CSLB before the license is processed — required for all initial applicants under BPC § 7058.5(b)

$450 renewal every two years; late costs $225 extra

Renewal period: every 2 years
Timely renewal: $450 (sole owner) or $700 (non-sole owner)
Delinquent renewal: $675 (sole owner) or $1,050 (non-sole owner) — that is the timely fee plus a $225 or $350 penalty
Retroactive reinstatement: under BPC § 7141.5, a completed renewal submitted within 90 days of expiration reinstates the license retroactively with no gap in the licensing record. After that window, renewals become delinquent — CSLB allows delinquent renewal for up to 5 years after expiration; only after 5 years does CSLB require a new original application
Continuing education: CSLB does not require continuing education for Class A renewals

Unlicensed Class A work risks jail time and a $5,000 fine

First-time unlicensed contracting in California is a misdemeanor under BPC § 7028: up to 6 months in county jail and a $5,000 criminal fine. CSLB also issues a civil administrative fine of $200 to $15,000 under BPC § 7028.7 (rising to a $1,500 minimum effective July 1, 2026). Class A contractors must also keep the right workers' compensation filing on record with CSLB — an expired or missing certificate can put an active license on hold.
