Welcome to the NHPD

The National Housing Preservation Database (NHPD) is an address-level inventory of federally assisted rental housing in the US, created in 2011 by the Public and Affordable Housing Research Corporation (PAHRC) and the National Low Income Housing Coalition (NLIHC), in an effort to provide communities with the information they need to effectively preserve their stock of public and affordable housing.


The NHPD is comprised of three tools to help you locate, research, and report on publically supported rental housing in your community.


Access the database and customize your search of affordable housing properties by location, funding stream, or subsidy end date.


Mapping Tool

Access interactive maps to view where affordable housing is located in your community, identify new affordable properties, and locate properties that are at risk of loss.


Preservation Profiles

Access our one-page profiles of the affordable housing inventory in your state that can educate the general public and lawmakers.
