Housing Opportunities for Persons with AIDS (HOPWA): HOPWA provides housing assistance and related support services for low-income persons with HIV/AIDS and their families. Program funds are distributed under a formula that is based on cumulative AIDS cases and area incidence. Grants are awarded from one of three programs: the HOPWA formula program which uses a statutory method to allocate HOPWA funds to eligible states and cities on behalf of their metropolitan areas; the HOPWA Competitive Program which is a national competition to select model projects or programs; and the HOPWA National Technical Assistance Funding which provides awards to strengthen the management, operation, and capacity of HOPWA grantees, project sponsors, and potential applicants for HOPWA funding.
