11. What
are the contractor license classifications?
The CSLB issues a license to contract in a particular trade or field of the
construction profession. Each separate trade is recognized as a
"classification." You may add as many classifications to your license as you can
qualify for.
The CSLB issues licenses for the following classifications:
- Class A General Engineering Contractor. The principal business is in
connection with fixed works requiring specialized engineering knowledge and skill.
- Class B General Building Contractor. The principal business is in
connection with structures that shelter and enclose persons, animals, chattels, or movable
property requiring in their construction more than two unrelated trades. The "B"
contractor may contract any single or multiple trade or craft without the additional
"C" specialty license.
- Class C Specialty Contractor. There are 40 separate "C"
license classifications for contractors whose construction work requires special skill and
whose principal contracting business involves the use of specialized building trades or
crafts. Manufacturers are considered to be contractors if engaged in on-site construction,
alteration, or repair.

Are there any special requirements for contractors who work with asbestos or other
hazardous substances?
Contractors who work with asbestos or other hazardous substances are regulated by the
United States Department of Labor, Federal Occupational Safety and Health Administration,
and the California Department of Industrial Relations, Division of Occupational Safety and
Health (DOSH), as well as by the CSLB. These contractors are subject to a number of
certification, registration, reporting, and safety requirements.
Following are some of the CSLB basic requirements:
- Before a license is issued, every licensee must complete, sign, and return the open-book
examination contained in the booklet, Asbestos: A Contractor's Guide and Open-Book
Examination. The booklet contains general information about asbestos-abatement
standards.
- Asbestos-abatement contractors must be certified by the CSLB. To become certified, a
contractor must take and pass an EPA-accredited asbestos-abatement course; complete the
Application for Asbestos Certification; pass a comprehensive Asbestos Abatement exam; and
register with the Asbestos Contractor Registration Unit of DOSH.
- Contractors who do hazardous substance removal work must be certified by the CSLB.
Contractors who do hazardous substance removal work must complete an Application for
Hazardous Substance Removal and Remedial Actions and pass a CSLB certification
examination. Any contractor who has a class "A" General Engineering,
"B" General Building, "C-36" Plumbing, "C-61 (D-40)" Service
Station Equipment and Maintenance (no longer issued), "C-12" Earthwork and
Paving, or "C-57" Well Drilling (Water) license is eligible to be certified.
In addition, contractors who install or remove underground storage tanks must hold this
certification. CSLB Board policy currently limits certified contractors doing underground
storage tank work as follows:
- General engineering "A" contractors may install and/or remove
underground storage tanks for any purpose at any location.
- Plumbing "C-36" contractors may install and/or remove any
underground storage tank that provides service to a building - including storage tanks for
service stations.
- Service station equipment and maintenance "C-61/D-40" contractors
may install and/or remove fuel underground storage tanks at service stations or any other
site up to a capacity of 20,000 gallons.
- General building "B" contractors may, in the course of work
performed under a contract that meets the requirements for the "B"
classification (see Question 11), install and/or remove an underground storage tank if
properly certified for hazardous substance removal and remedial actions.
