Licensing Paths for California Construction Contractors

In California, there are two main contractor license types for residential and general construction work: General Building Contractor (B) and Residential Remodeling Contractor (B-2).

General Building Contractor (B) - This classification covers building or managing construction projects involving structures like homes, offices, or other buildings. To qualify, the contractor must use at least two different types of trades or crafts (such as plumbing and electrical) on a project. This license allows for broad construction work, but it does not cover specialized areas like fire protection or well drilling unless the contractor holds the proper specialty license or hires someone who does.

Residential Remodeling Contractor (B-2) - This classification focuses specifically on remodeling existing wood-frame homes. To take on a project, the contractor must use at least three different trades or crafts—such as painting, flooring, and tiling—within a single contract. However, B-2 contractors are not allowed to make structural changes to load-bearing parts of a home or perform major electrical, plumbing, or HVAC work unless they are properly licensed or subcontract that work to someone who is.
