California faces a severe housing shortage and increasingly devastating climate disasters. A critical solution to these interlocking issues is affordable housing investment in walkable, transit-connected neighborhoods — and a key component to advancing that production is the availability of land to build on.

Transit agency-owned parcels are an excellent opportunity to use public land for public good. Many California transit agencies have successfully used their land for affordable housing development, especially in major metropolitan areas. Housing on transit agency land can achieve multiple positive outcomes: addressing housing needs, increasing ridership, reducing driving, meeting climate goals, and providing new revenue sources for transit agencies.

Policymakers, advocates, and public partners seek ways to unlock transit agency land for housing, but there is currently no statewide, publicly accessible data on how much land California transit agencies own — and no way to comprehensively assess its availability, characteristics, or potential for affordable housing development. To that end, this report:

  • Compiles and shares data on transit agency-owned parcels in California
  • Analyzes and reports on parcel characteristics 
  • Recommends strategies to increase use of transit agency land for housing
