The IBC, IRC and IFC along with the first four chapters of the IEBC are adopted and then amended by the California Building Standards Commission.
The tall mass timber provisions went into effect in 2021.
Code amendments do not involve subjects that adversely impact wood construction. In fact, the BSC adopted the Mass Timber provisions from the 2021 IBC early. They were effective July 1, 2021.
The BSC has recently adopted the 2021 IBC, IRC, IFC and IEBC with CA amendments. Effective for CA State projects July 1st , 2022 and effective throughout the state Jan 1st, 2023. Cities, Counties, etc. can produce amendments so long as they are not less restrictive that the State of CA adopted codes.
Expected date most recent code will be adopted: January 1st, 2023.
