Title 24 windows · San Diego, CA

California Title 24 window requirements in San Diego, CA

California Title 24 is the state's building energy efficiency standard, and it sets performance requirements for replacement and new-construction windows based on climate zone. Permitted window projects in San Diego County must meet the U-factor and SHGC limits for their specific climate zone.

San Diego: Mild central-city climate with strong sun on south and west elevations, where older stucco homes often still run single-pane aluminum windows that leak heat and let street noise in

What to know

  • Title 24 sets maximum U-factor (heat flow) and SHGC (solar heat gain coefficient) limits by California climate zone
  • San Diego County spans multiple climate zones, so requirements can differ between coastal and inland cities
  • NFRC labels on the window document the specific U-factor and SHGC ratings needed for permit inspection sign-off
  • A permitted window replacement that does not meet Title 24 is a disclosure issue if the home is sold later
