The bill establishes a two-year housing assistance pilot program for youth enrolled in extended foster care in Washington State, aimed at preventing and alleviating homelessness among this vulnerable population. The program will provide rental assistance and associated housing fees to up to 50 eligible youth who are either experiencing homelessness or at imminent risk of it. The assistance will be available for up to 24 months, with specific criteria for rental contributions based on fair market rent and the youth's adjusted gross income. The Department of Children, Youth, and Families will oversee the program, potentially contracting with external entities to manage its operations.

Additionally, the bill mandates a transition planning process for youth in extended foster care, which must begin at least three months before their 21st birthday. This process will include assessing the youth's housing and financial stability, assisting them in applying for federally funded housing vouchers, and providing referrals to various support services. By June 30, 2029, the department is required to report to the legislature on the program's outcomes, including the number of youth served, the duration and amount of assistance provided, and demographic information about the participants.
