RentCafe.com analysis of Yardi data as of July 2025

San Diego’s apartment development over the past decade has been highly concentrated due to geographic constraints and limited land availability. New construction has focused on downtown, transit corridors, and select inland areas where zoning and infrastructure support higher density.

Employment growth in military, healthcare, education, biotechnology, and tourism continues to influence where new housing is delivered. Transit expansion — particularly light rail extensions — has reinforced development along rail corridors, while established coastal and suburban areas have seen comparatively limited new supply.
