The bill establishes new requirements for individuals experiencing homelessness in Washington State, specifically focusing on substance use treatment as a condition for receiving housing services. It mandates that all individuals housed in transitional or permanent supportive housing be assessed for substance use disorders. If an individual is found to have a substance use disorder, they must comply with treatment recommendations and abstain from alcohol and unprescribed drugs to maintain their eligibility for housing. This initiative aims to promote recovery, long-term stability, and accountability within state-funded housing programs.

Additionally, the bill requires grant recipients to track participants through the Washington homeless client management information system, documenting assessments, services provided, and compliance with treatment. By December 1, 2026, and annually thereafter, grantees must submit reports detailing the number of participants served, those assessed with substance use disorders, and compliance durations with treatment conditions. This structured approach is intended to enhance oversight and ensure that housing programs are effective in addressing the needs of individuals with substance use disorders.
