Housing % of Units Built Since 2010, by Zip Code (ZCTA5) — San Diego Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of post-2010 housing construction cluster in the downtown San Diego core and select southern zip codes near Chula Vista, where units built since 2010 exceed 20-30% of total housing stock, likely reflecting intensive infill and master-planned development. A secondary pocket of newer construction appears in the inland north near Encinitas, contrasting sharply with the surrounding coastal and suburban zip codes that show minimal recent building activity. The large eastern zip codes and established suburban communities like Poway, Santee, and La Mesa consistently register low percentages of new construction, suggesting these areas are largely built out with limited greenfield or redevelopment opportunities.
