Division of the State Architect (DSA)
The Division of the State Architect is an agency within the State of California Department of General Services. Along with several other state agencies, the DSA proposes changes to the California Building and Administrative Code (Title 24) through the Building Standard Commissions rulemaking process.
The DSA also develops and publishes interpretations of code, policies, and procedures that are necessary for stakeholder understanding and coordination of enforcement across the DSA regional offices.
In addition, the DSA can provide code citation and point out code language. However and to avoid potential confusion, the DSA does not have any legal authority to interpret provisions of the code. The legal authority for interpretation of the code is exclusively with the local jurisdiction.
Parts 1 through 12 of the California Code of Regulations’ Title 24 lay out California’s building regulations. “Title 24” is comprised of the regulations that govern the construction of buildings in California.
