On April 20, 2010 the Department of Housing & Urban Development will issue a proposed rule to define certain terms in the Homeless Emergency Assistance & Rapid Transition to Housing Act of 2009 (HEARTH Act). The HEARTH Act defines the terms "homeless," "homeless individual," "homeless person," and "homeless individual with a disability," but these definitions contain terms that require clarification and input from the public.
