The McKinney-Vento Homeless Assistance Act is the primary federal statute that addresses the issues of homelessness in the United States. Three grant programs administered by HUD under this statute (the Supportive Housing program, the Shelter Plus Care program, and the Emergency Shelter Grants program) each impose a matching requirement for a grant awarded by HUD under the program. This rule codifies, in the regulations governing these programs, the scope of the match requirement, and the responsibility of the recipient of the grant to ensure that the funds that the recipient uses to satisfy HUD's match requirements are not prohibited to be used for this purpose under any statute that may govern the matching funds. The scope of the match and the responsibility to ensure that a match is a permissible match is not a new interpretation, or new responsibility, respectively. HUD has determined, however, that codification in regulation benefits grantees, especially new recipients, since codified regulations present an easy locatable source for permanent program policies and requirements.
