California Title 24 (Building Energy Efficiency Standards) sets strict requirements for window U-factor and SHGC — all replacement windows must meet these standards regardless of home age.
In San Francisco County, the average window replacement costs $400–$900 per window installed. Bay Area premium: $600–$1,200. Whole-house (14 windows): $7,000–$18,000 depending on frame material and glass package.. Getting multiple quotes from licensed contractors is the best way to protect yourself from overpriced bids.
ENERGY STAR window rebates available through PG&E, SCE, SDG&E, and SMUD. Typical rebates: $25–$100 per window. Title 24 compliance required for all window replacements.
CA climate varies dramatically: Bay Area needs good U-factor for cold fog; SoCal needs low SHGC to block solar heat; High Desert needs triple-pane for temperature swings.
