Most permitted ADUs and JADUs in Climate Zone 14 require a Title 24 CF1R report — the same statewide standard that applies to accessory dwelling units across California.
ADUs and Title 24 in Zone 14
Detached, attached, and garage-conversion ADUs generally require a CF1R because they create or alter conditioned living space. Title 24 is a statewide California energy code. Climate Zone 14 does not have its own separate rules — the same statewide standards apply, with the energy budget calibrated to this zone's climate. Your project's exact requirements are determined when your specific address is modeled in CEC-approved compliance software.
