How do Title 24 and CALGreen affect new construction in Fremont?

Fremont is in California Energy Code Climate Zone 3. Title 24 sets the envelope, HVAC, and renewable requirements; CALGreen sets the green-building baseline. Both are enforced by City of Fremont Community Development Department — Building & Safety at plan check and inspection.

What changes the answer in Fremont.

California Energy Commission Climate Zone 3. New single-family homes must comply with the current Title 24 Part 6 envelope, HVAC, hot-water, and rooftop solar-PV requirements. CALGreen Part 11 mandatory measures (≥65% C&D waste diversion, water-efficient fixtures, indoor-air-quality measures) apply to all new homes. Fremont may layer reach-code or local green-building amendments — confirm the current adopted ordinance at intake.
