The Texas Department of Housing and Community Affairs is the state agency responsible for affordable housing, community and energy assistance programs, colonia activities, and regulation of the state's manufactured housing industry. The Department currently administers $2 billion through for-profit, nonprofit, and local government partnerships to deliver local housing and community-based opportunities and assistance to Texans in need. The overwhelming majority of the Department's resources are derived from mortgage revenue bond financing and refinancing, federal grants, and federal tax credits.

The mission of the Texas Department of Housing and Community Affairs is to administer its assigned programs efficiently, transparently, and lawfully and to invest its resources strategically and develop high quality affordable housing which allows Texas communities to thrive.

The Department accomplishes this mission by acting as a conduit for federal grant funds for housing and community services. However, because several major housing programs require the participation of private investors and private lenders, TDHCA also operates as a housing finance agency.
