The official regulatory code in California is called the California Code of Regulations (C.C.R.) (formerly called the California Administrative Code). The C.C.R. is divided into 28 numbered titles, each of which covers a broad subject area (e.g., Title 5 covers education, Title 19 covers public safety). Each title is further divided by administrative agency and subdivided by topic and eventually broken down into individually numbered sections. A citation to a C.C.R. section includes the title number and section number.
The official print version of the C.C.R. consists of frequently updated loose-leaf binders. The C.C.R. is also available on LexisNexis Academic. From the “State Statutes and Regulations Search" page, click on "Advanced Options" and then check the "Administrative Code" and "California" boxes. There is also a publicly accessible electronic version of the C.C.R.
