"Housing First programs don’t require participants to meet any preconditions, and they are built on the idea that secure, affordable, and permanent housing must be available before people can work on other challenges, such as mental health or substance use disorders." The rigorous study "used a randomized controlled trial, the gold standard for determining a program’s impact, that included 724 people: 363 people were in the treatment group (referred to the supportive housing program) and 361 people were in the control group (receiving services as usual in the community)." Its results show "that supportive housing, through a Housing First approach, not only ends chronic homelessness and helps people find stability, but also reduces jail days and lowers the public costs of the homelessness-jail cycle."
