Code Development & Analysis

2010 Califonia Building Standards Code
(Triennial Code Adoption Cycle)

The Office of the State Fire Marshal (SFM), along with other state agencies, is in the process of developing and proposing Building Standards for the 2010 California Building Standards Codes. The general purpose is principally intended to update and codify a new edition of the California Building Standards Code (California Code of Regulations, Title 24) that adopt by reference more current editions of the model codes. The more recent editions of the following model codes proposed to be adopted by reference are:

  • 2009 International Building Code (IBC)
  • 2009 International Fire Code (IFC)
  • 2009 International Residential Code (IRC)
  • 2008 National Electrical Code (NEC)
  • 2009 Uniform Mechanical Code (UMC)
  • 2009 Uniform Plumbing Code (UPC)

The objective is to develop an adoption package that includes model code language and current applicable California amendments. The intent is that the final adoption package will include amendments necessary to reasonably maintain a substantially equivalent level of fire and life safety in California. This proposed action will:

  • Repeal the adoption by reference of the model code and incorporate and adopt by reference in its place more recent model codes for application and effectiveness in the 2010 California Building Standards Code pursuant to Health and Safety Code 18928. Health and Safety Code 18928 requires any state agency adopting model codes to adopt the most recent edition.
  • Repeal certain amendments to the model codes and/or California building standards not addressed by the model code that are no longer necessary pursuant with Health and Safety Code 18930(a)(7).
  • Adopt new building standards or necessary amendments to the model code that address inadequacies of the model codes as they pertain to California laws.
  • Bring forward previously existing California building standards or amendments, which represent no change in their effect from the 2007 California Building Standards Code.
  • Codify non-substantive editorial and formatting amendments for the format based upon the more recent edition of the model codes.

The State Fire Marshal, by State Law, is responsible for the coordination of the State's fire and life safety codes. The State Fire Marshal must review the proposed regulations of State Agencies that promote fire and life safety before the regulations can be submitted for approval. According to a timetable being considered by the State Agencies, the entire SFM package submitted to the California State Building Standards Commission (CBSC) June 2009.
