Evidence-Based Practices for Solving Homelessness and Increasing Affordable Housing in California

Evidence-based practices are founded on the integration of research results with clinical expertise, which helps professionals make decisions on proven results and not on personal experience or anecdote as has all too often been the case in homelessness service provision. Examples of these include:

• Permanent supportive housing, an evidence-based housing intervention for persons who have a disabling condition and are in need of subsidized housing for which they pay no more than 30% of their adjusted monthly income. On-site and off-site services are provided. Services may be short-term, sporadic, or ongoing. Supportive services may include education, emergency assistance, employment, health care, mental health care, substance use counseling and treatment, and trauma care.
• Housing First, an evidence-based practice recognized by the federal government and the State of California. The practice involves providing permanent housing as a necessary precursor to receiving supportive services. The practice also involves removing barriers to housing related to income and treatment that have prevented persons from obtaining and maintaining their housing.
