Welcome to the California Building Standards Commission

The California Building Standards Commission (CBSC) is authorized by California Building Standards Law to administer the many processes related to the development, adoption, approval, publication, and implementation of California's building codes.

The California Building Standards Code, Title 24 serves as the basis for the design and construction of buildings in California. Improved safety, sustainability, maintaining consistency, new technology and construction methods, and reliability are paramount to the development of building codes during each Triennial and Intervening Code Adoption Cycle

California’s building codes are published in their entirety every three (3) years.  Intervening Code Adoption Cycles produce Supplement pages half-way (18 months) into each triennial period.  Amendments to California’s building standards are subject to a lengthy and transparent public participation process throughout each code adoption cycle.


Commission News

Exterior Elevated Elements Subcommittee research

Following the Berkeley balcony collapse of 2015, the California Building Standards Commission (CBSC) formed an ad hoc subcommittee comprised of two members (Commissioners Kent Sasaki and Steven Winkel). The purpose of this subcommittee is to review reports and other information regarding failures of this type and to possibly make regulatory or statutory recommendations to the CBSC and/or state agencies that have authority to amend the California Building Standards Code (Cal. Code Regs., Title 24).

The CBSC's staff has built a webpage and repository for related data, studies and other information for the Subcommittee's use.

To contribute additional information, you may email your comment(s) to cbsc@dgs.ca.gov and place "EEE" in the subject line.

AB 1732: Single-user restrooms (Chapter 818, Statutes of 2016)

CBSC has received calls concerning new signage requirements for the identification of single-user toilet facilities as all-gender toilet facilities in response to Assembly Bill 1732 (Chapter 818, Statutes of 2016). The Division of the State Architect (DSA) recently published Information Bulletin 17-01: Identification of Single-User Toilet Facilities as All-Gender, which provides information as an aid for compliance with new state law requirements. Additionally, DSA issued BU 17-01-01 Identification of Single-User Toilet Facilities as All-Gender: Frequently Asked Questions, which is a supplement to the original document and further answers common questions raised by facility managers and design professionals. Please note, for questions concerning specific occupancies affected, applicability or compliance, contact the local enforcement agency.
