The CASp program is designed to meet the public's need for experienced, trained, and tested individuals who can inspect buildings and sites for compliance with applicable state and federal construction-related accessibility standards. DSA develops regulations that govern the administration of the CASp Program. We develop and propose changes to the Title 21 Voluntary Certified Access Specialist Program Regulations, as well as the related forms and publications (incorporated into regulation by reference). Proposed and amended regulations become law after DSA completes the rulemaking process in compliance with standards set forth in California’s Administrative Procedural Act and regulations adopted by Office of Administrative Law (OAL).

The Division of the State Architect submitted proposed changes to the CASp Program regulations to the Office of Administrative Law (OAL) on April 6, 2021 for review and approval. The revised regulations were approved by OAL and will be effective on July 1, 2021. 

The Final Express Terms and the Final Statement of Reasons are available for your review:
