California Title 24 window requirements in Mission Valley, 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.
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
