“HUD collects LIHTC data at the property level and the tenant level. The LIHTC database, created by HUD and available to the public since 1997, contains information on 48,672 projects and 3.23 million housing units placed in service between 1987 and 2018. Although some data about the program have been made available by various sources, HUD's database is the only complete national source of information on the size, unit mix, and location of individual projects. HUD also collects information on certain demographic and economic characteristics of households residing in LIHTC properties from state housing finance agencies that administer the LIHTC program. This page provides access to the property and tenant level data and also to data on Qualified Census Tracts and Difficult Development Areas designated by HUD."
