There are nearly 47,000 homeless people living on the streets or in shelters in Los Angeles County. Their problems are all complex, but none are as challenging as those of the chronically homeless, who suffer from mental illness or substance abuse or a physical disability. Over the last few decades, experts have concluded that what this group needs most, generally speaking, is permanent supportive housing, the kind that comes girded with social services such as mental health care, primary care, drug treatment and case management by a professional.
