2017 Brings in the New 2016 California Building Code

A New Code

2016 California Building Code

2016 California Building Code

On January 1, 2017, the State of California is adopting the 2016 California Building Code.  This affects the design and construction of new and existing buildings.  When and how the 2016 CBC will affect a specific building will depend on the local jurisdiction.

The 2016 California Building Code is based on the 2015 International Building Code.  Various California agencies add their own amendments to the 2015 International Building Code.  The 2015 International Building code is based on the following:

  • ASCE 7-10 including Supplement No. 1
  • ACI 318-14
  • AISC 360-10
  • AISC 314-10
  • TMS 402-13
  • TMS 602-13
  • 2015 AF&PA NDS
  • 2015 WFCM

The prior version of the building code 2013 California Building Code was based on the 2012 IBC.  Many of these code references to the 2013 CBC and the 2012 IBC have been updated.

California has its own amendments so that the 2016 CBC is a little different than the 2015 IBC.  For instance, the reference to the loading requirements of ASCE 7-10 Supplement No. 2 is added to the California Building Code.  Generally, most of the differences between the 2016 CBC and the 2015 IBC relate to school and hospital construction.

Free versions of the 2015 IBC2016 CBC, and other building codes are available.

Transitioning to ACI 318-14

One of the 2015 IBC references is American Concrete Institute’s Building Code Requirements for Structural Concrete and Commentary ACI 318-14.  ACI 318-14 has been completely reorganized from the previous ACI 318-11 edition.  Because of this reorganization, ACI has published free transition keys between ACI 318-11 and ACI 318-14, so that a designer can bridge the differences between the two editions.  These transition keys are in both English and Spanish.
