California Climate Zone 14 is one of the 16 official climate zones defined by the California Energy Commission (CEC) and used throughout the Title 24 energy code.
What the zone means
The CEC divides California into 16 climate zones, each with its own energy budget that reflects local temperature, humidity, and solar conditions. Climate Zone 14 is one of these. 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.
How your zone is determined
Your project's climate zone is assigned by its exact address — often by ZIP code — not simply by city name. A single city can fall within more than one zone. When you order, we determine your zone from your project address and model the report accordingly. Learn more about how California climate zones work.
