The bill creates a new "extended foster care housing program" by adding sections to chapter 74.13 RCW and adds a transition-planning requirement in chapter 13.34 RCW. The new law establishes a program to provide rental assistance and associated housing fees to eligible youth who are receiving extended foster care services under RCW 13.34.267 and who are either experiencing homelessness as defined in RCW 13.34.030 or, if funding is provided, at imminent risk of homelessness. The program is intended to provide a benefit equivalent to the federal Foster Youth to Independence program so youth can receive housing assistance while dependent and later access the federal program when they turn 21. Key program rules and procedural changes include a department-led competitive procurement to contract with entities to operate the program (with the department allowed to operate functions if no contractor is available), rental assistance provided for up to 36 months but not beyond a youth's 21st birthday, and assistance amounts based on fair market rent in the youth’s location. Eligible youth must pay no more than 30 percent of their adjusted gross income toward rent (including any extended foster care subsidy); if rent and utilities exceed fair market rent for the location, the youth’s contribution may not exceed 40 percent of monthly adjusted gross income. The department must ensure access for all eligible youth, collect annual housing-status data on youth in extended foster care, and conduct a transition planning process at least three months before a youth’s 21st birthday that includes assessing housing and financial stability, assisting applications to federally funded housing voucher programs when applicable, and providing referrals to housing and other supportive services. The change is the creation of a new program and related procedural requirements in state law; it does not create a new crime or change penalties. Important details are unclear in the extracted text: the specific agency referred to as "the department" is not identified, statutory definitions for "fair market rent" and "adjusted gross income" are not provided here, and funding, procurement timing, eligibility administration, and other operational or budgetary specifics are not included.

If enacted, eligible young people in extended foster care who are homeless or imminently at risk (the latter only if money is appropriated) would be able to get rental help while still in care for up to 36 months but not past their 21st birthday. Their monthly rent share would be limited to 30 percent of their adjusted gross income (rising to 40 percent only if rent plus utilities exceed local fair market rent), the assistance would be tied to local fair market rents, and the program is meant to let them receive state help first and then move onto federal housing voucher programs when they age out. Important details that affect who actually gets help—such as the exact meanings of “fair market rent” and “adjusted gross income,” which state agency runs the program, and how much money will be appropriated—are not specified here. The state agency named in the chapter would need to run a competitive procurement or operate the program itself, ensure every eligible youth can access assistance, collect annual housing-status data on youth in extended care, and do a housing and benefits transition plan at least three months before a youth turns 21. That creates new administrative duties and likely new contracting and budget needs; because eligibility for some youth is “subject to appropriations” and procurement details aren’t provided, the practical reach and cost of the program could be constrained by available funding and the state’s capacity to run or contract out the services.
