The C-22 Asbestos Abatement classification is the full license for contractors whose principal business is removing, containing, and encapsulating asbestos in buildings, a tightly regulated, registration-required specialty.
Requirements
About the Exam
License renews every 2 years. Governing code: CCR §832.22
About this classification
A C-22 Asbestos Abatement Contractor performs the abatement of asbestos-containing construction materials, including containment, encapsulation, removal, and disposal, in compliance with Cal/OSHA (DOSH) requirements. The C-22 is a full stand-alone license whose principal business is asbestos work.
Under the California Code of Regulations (Title 16, §832.22), a C-22 contractor performs "the abatement, including containment, encapsulation, or removal, and disposal of asbestos containing construction materials." Before doing this work, the contractor must hold DOSH (Cal/OSHA) asbestos-abatement registration under Labor Code §6501.5.

The CSLB exam
California requires you to pass a two-part CSLB exam: the Law & Business exam (the same for every classification) and the C-22 Asbestos Abatement trade exam. CSLS has observed scores of 65% for Law & Business and 69% for the C-22 trade exam. CSLB does not publish fixed passing scores and may vary them by exam version.
Same for all classifications
Asbestos Abatement-specific
18+ is CSLB's normal applicant path. A minor may qualify only after a court appoints a guardian (BPC §7065.5). You also need a valid SSN/ITIN and 4 full-time-equivalent years of journey-level asbestos abatement experience within the past 10 years; CSLB prorates part-time work. Up to 3 years may be substituted with approved education or apprenticeship.
Submit your application, get fingerprinted, and pay the $450 application fee. Processing times vary; check the CSLB's current processing times.
Prepare for both exam parts, on your own or with a CSLS exam prep program. 99% of CSLS students pass on their first try, backed by our 100% Money-Back Guarantee.
