The CSLB issues licenses to contract in particular trades or fields 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:
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 any structure built, being built, or to be built, requiring in its construction the use of at least two unrelated building trades or crafts; however, framing or carpentry projects may be performed without limitation. In some instances, a general building contractor may take a contract for projects involving one trade only if the general contractor holds the appropriate specialty license or subcontracts with an appropriately
licensed specialty contractor to perform the work.Class “C”—
Specialty Contractor. There are 41 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.
You may obtain a license in any of the specialty classifications listed below. For a detailed description of these classifications, see the CSLB Web site, or consult the CSLB Rules and Regulations in the California Contractors License Law .
