With the generous support of the William S. Abell Foundation, the Urban Institute (UI) surveyed District permanent supportive housing (PSH) agencies and specific PSH projects, asking their staff to detail current projects and future ambitions. This research brief is an analysis of the stock of PSH in the District as of early fall 2008, demographic information on PSH tenants at that time, and a look at how the District might move forward toward fulfilling its commitment to create 2,500 new units of PSH and ultimately eliminating chronic homelessness.
