There is a large and growing evidence base demonstrating that Housing-First is an effective solution to homelessness. Consumers in a Housing-First model access housing faster and are more likely to remain stably housed. This is true for both PSH (Permanent Supportive Housing) and rapid re-housing programs. PSH has a long-term housing retention rate of up to 98 percent. Studies have shown that rapid re-housing helps people exit homelessness quickly—in one study, an average of two months—and remain housed. A variety of studies have shown that between 75 percent and 91 percent of households remain housed a year after being rapidly re-housed.
More extensive studies have been completed on PSH finding that clients report an increase in perceived levels of autonomy, choice, and control in Housing-First programs. A majority of clients are found to participate in the optional supportive services provided, often resulting in greater housing stability. Clients using supportive services are more likely to participate in job training programs, attend school, discontinue substance use, have fewer instances of domestic violence, and spend fewer days hospitalized than those not participating.
Finally, permanent supportive housing has been found to be cost-efficient. Providing access to housing generally results in cost savings for communities because housed people are less likely to use emergency services, including hospitals, jails, and emergency shelter than those who are homeless. One study found an average cost saving on emergency services of $31,545 per person housed in a Housing-First program over the course of two years. Another study showed that a Housing-First program could cost up to $23,000 less per consumer per year than a shelter program.
