In 2005, the Hilton Foundation gave CSH a five-year grant to launch an initiative in Los Angeles County to reduce the number of long-term homeless people, with a special focus on reducing homelessness among people with serious mental illness. To promote these outcomes, CSH has been using grant money to: fund predevelopment work on various permanent supportive housing (PSH) projects, invest in building the capacity of supportive housing providers, work with public officials and other key stakeholders in the county and selected cities (Los Angeles, Long Beach, Santa Monica, and others) to stimulate increased commitment to PSH, support the Special Needs Housing Alliance, and pursue other activities with City and County of Los Angeles officials and agencies.
