What a C-22 Contractor Can Do
CSLB definition: An asbestos abatement contractor performs abatement, including containment, encapsulation, or removal, and disposal of asbestos containing construction materials, as defined in Section 6501.8 of the Labor Code, in and on buildings and structures. All work must be done in accordance with the regulations of the Division of Occupational Safety and Health (DOSH). (California Code of Regulations, Title 16, Division 8, Article 3; condensed. See the full text on CSLB.ca.gov.)
Typical C-22 work
- Asbestos removal and disposal
- Containment and encapsulation
- Abatement before demolition or remodeling
- Documentation that meets DOSH requirements
Needs a different license
- Rebuilding or repairing the retained structure
- Other hazardous substance removal and remediation
CSLB will not issue a C-22 license unless the applicant is registered with DOSH (or has an active DOSH registration application), and C-22 holders must complete DOSH registration training. C-22 contractors also may not file a workers’ compensation exemption.
C-22 License Requirements
CSLB uses the same core requirements for every classification. For the C-22, the qualifying individual (you, or the RMO/RME for a company) must:
- Be at least 18 years old.
- Have at least four full years of experience in asbestos abatement work within the last ten years, as a journeyman, foreman, supervising employee, contractor or owner-builder.
- Have that experience certified by someone with firsthand knowledge of your work, such as an employer, foreman, fellow journeyman, building inspector or homeowner.
- Pass the Law & Business exam and the C-22 trade exam, and complete CSLB’s asbestos open-book exam.
- Complete Live Scan fingerprinting and CSLB’s background review.
You may receive up to three years of credit toward the four-year requirement for technical training, apprenticeship or related education, but at least one year must be practical experience. There is no education requirement to get a California contractor license.
How to Get a C-22 License: Step by Step
- Confirm your classification. Compare your work with the C-22 scope above and the related classifications below.
- Document your experience. Gather proof of four years of asbestos abatement experience and line up a qualified person to certify it.
- Apply to CSLB. Submit the original application with the $450 fee. CSLP can help prepare your application so it is not returned for corrections.
- Get fingerprinted. Complete Live Scan once CSLB accepts your application.
- Study and pass your exams. Pass the Law & Business exam and the C-22 trade exam. Both are multiple choice.
- Meet issuance requirements. File your $25,000 contractor bond, workers’ compensation information, asbestos open-book exam and the initial license fee.
