HCD’s Guide to Affordable Housing Preservation Laws explains how these laws work to preserve affordable homes in California. The Guide has been updated to include AB 2926 (effective January 1, 2025) and AB 1529 (effective January 1, 2026) amendments. The updated Guide highlights the importance of preferential treatment for Qualified Entities proposing to preserve affordability. 
The Guide includes information on the requirements related to:

  • Registering as a Qualified Entity interested in bidding on affordable properties
  • The process for sales of affordable homes, and the priority for maintaining affordability
  • Tenant and government partner notifications of expiring affordability
  • The consequences for not complying with affordable housing preservation laws
