California Asbestos Abatement (C-22) Contractor License

The California Asbestos Abatement (C-22) contractor license allows you to perform 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 performed and all documentation prepared by an asbestos abatement contractor shall be done in accordance with regulations and requirements of the Division of Occupational Safety and Health (DOSH) of the Department of Industrial Relations.

CSLB issues a C-22 Asbestos Abatement license and a separate Asbestos Certification. C-22 licensees may contract for asbestos abatement with no limitations; those who are certified may only perform abatement work within the license classification they hold. To receive either a C-22 license or an Asbestos Certification a contractor must:

  • Take and pass an EPA-accredited asbestos abatement training course;
  • Register with the Asbestos Contractors’ Registration Unit of DOSH;
  • Submit an application and all required paperwork to CSLB;
  • Demonstrate four years of relevant journey-level work experience; and
  • Pass the appropriate exam(s).

How to get the Asbestos Abatement (C-22) contractor's license in California?

  1. Determine Eligibility: Each license requires a qualifier who directly supervises and controls the construction operations conducted under the license. Must be at least 18 years old and have four years minimum journeyperson, foreperson, supervising employee, or contractor work experience, in the last 10 years, in the Asbestos Abatement (C-22) trade.
  2. Verifying Work Experience: After meeting the basic eligibility requirements, the qualifier could be randomly selected to provide documentation that they meet the minimum work experience requirements. Having this documentation ready beforehand can make this process easier if your application is selected for review. The experience listed on the application must be verifiable, and people with firsthand knowledge of that experience must certify the accuracy of the information provided to CSLB on the Certification of Work Experience form.
  3. Complete Application: Must fill out the Original Contractor, Additional Classification, or Replacing the Qualifying Individual application form.
  4. Submit Application and Required Fees: For the current list of fees visit the California CSLB Fees page .
  5. Fingerprint Requirement after CSLB Review of Application: For information on fingerprinting, visit the CSLB Fingerprinting Requirement page.
  6. Schedule the Exams: Once the application is submitted the CSLB will send you a 'Notice to Appear for Examination." Upon receipt, the business exam and a Asbestos Abatement (C-22) exams must be scheduled and passed.
  7. Contractor Bond: All applicants must submit to CSLB a contractor bond or cash deposit payable to CSLB in the amount of $15,000. CSLB does not issue bonds.

The CSLB will either issue your license or contact you if they need further information.
