B.C-22 Asbestos Abatement
C.C-33 Painting and Decorating

Explanation: The C-22 Asbestos Abatement contractor classification from the Contractors State License Board (CSLB) is required for performing asbestos abatement work in California. The C-22 classification authorizes containment, encapsulation, removal, and disposal of asbestos-containing construction materials. DOSH registration is a prerequisite for the C-22 license.
