Why Climate Zone 3 Matters Here
Climate Zone 3 covers Antioch and is characterized by mild, marine-influenced conditions with minimal temperature swings. Title 24 software accounts for this automatically, but it changes which upgrades make the most sense for your project.

Frequently Asked Questions

It depends on the compliance path used in your energy model. Certain prescriptive credits — duct sealing, refrigerant charge verification, air leakage testing — trigger a HERS verification requirement. We flag these clearly in every Antioch report we prepare.
