Preservation Clearinghouse

The California Housing Partnership’s Preservation Clearinghouse is the state’s most comprehensive source of information on subsidized affordable housing at risk of losing its affordable status and converting to market-rate housing. The Partnership maintains the only comprehensive database of all HUD subsidized properties, USDA Section 515 rural properties, and properties financed with Low Income Housing Tax Credits in California. We use the database to identify affordable properties that are at risk and should be targeted for preservation.

The California Housing Partnership makes our database results available to local governments and nonprofit housing partners upon request. If interested, please request a copy of our Preservation Database Access Policy by contacting
