California Administrative Law Research Guide: Home


As a general rule, regulations are different from statutes: regulations are enacted by administrative agencies, while statutes are enacted by the legislature (or by voter initiative). The authority to adopt, amend, and repeal regulations is granted to an agency by either constitutional provision or statute. When exercising this authority, agencies must follow the procedures set forth in the California Administrative Procedure Act (Government Code 11340 et. seq.). This guide outlines how to locate and update California regulations. Some agencies have established administrative tribunals that adjudicate certain disputes.This guide will help you locate those agency decisions.

Finding California Regulations

Office of Administrative Law

The Office of Administrative Law (OAL) publishes three primary regulatory publications for California: (1) the California Code of Regulations (CCR); (2) the California Code of Regulations Supplement (CCR Supplement); and (3) the California Regulatory Notice Register (Notice Register).

The CCR contains regulations duly adopted pursuant to the Administrative Procedure Act (APA) by California state agencies. Generally speaking, after OAL approves a proposed regulation adopted by a state agency, it then files the regulation with the Secretary of State.  The CCR is updated weekly through the publication of the CCR Supplement (Register). The CCR Supplement (Register) is commonly and historically referred to as the “Register.”

Current California regulations are officially compiled in the print Barclays California Code of Regulations (CCR) (KFC35 .A22 - 4th Floor Stacks).  Barclay's publishes a Master Index to the current CCR. It is the last two volumes in the set. One volume contains statute to regulation tables; the second volume contains a subject index. The subject index is the place to look if you do not have a citation to a regulation. 

The current CCR is available online. The default view is to browse but you can search it as well. Thomson Reuters maintains this publicly available database so it is best searched using Westlaw terms and connectors. You can also locate an agency's contact information and link to the agency's sections in the CCR. Title 6 (Governor) and Title 24 (Building Codes) are not included on this website.

The California Building Standards Code, has 12 parts:

Part 1 - California Building Standards Administrative Code
Part 2 - California Building Code
Part 2.5 - California Residential Building Code
Part 3 - California Electrical Code
