Home Energy Upgrade Potential Map - San Diego Region

This map shows the median build year of homes in the San Diego region by census tract. Areas with older homes are shaded in red.

Older than 1930
1930 - 1949
1950 - 1969
1970 - 1979

1990 - 1999
2000 or newer

California’s Building Energy Efficiency Standards (Title 24, Part 6) took effect in 1978 and have become progressively more stringent over time. Thus, older homes typically have more opportunity for energy efficiency improvements like the ones performed through Home Upgrade.
