The Housing Opportunities for People with AIDS (HOPWA) program, with funds from U.S. Department of Housing and Urban Development (HUD), helps grantees provide housing assistance and related supportive services to individuals affected by HIV/AIDS. There are two types of grantees: non-profit organizations, which win funds based on competition; and municipalities, which are awarded funds based on the number of residents affected by HIV/AIDS. HOPWA funds may be used for a wide range of housing, social services, program planning, and development costs. These include, but are not limited to, the acquisition, rehabilitation, or new construction of housing units; costs for facility operations; rental assistance; and short-term payments to prevent homelessness. HOPWA funds also may be used for health care and mental health services, chemical dependency treatment, nutritional services, case management, assistance with daily living, and other supportive services.
