The bill addresses the affordable housing shortage in Washington State's urban growth areas by promoting the development of accessory dwelling units (ADUs). It aims to streamline local regulations that may impede the economic feasibility of ADUs, encouraging local governments to adopt programs that incentivize their development for long-term housing. The legislation emphasizes enhancing housing density, supporting multigenerational living, and reducing intergenerational poverty through increased home ownership. It also amends existing laws related to comprehensive planning, requiring local plans to analyze housing needs across various income levels and types, while addressing potential racially disparate impacts and displacement.

Additionally, the bill clarifies that concurrency requirements for transportation facilities do not apply to statewide significant facilities, with specific exceptions for island counties. It updates the timeframe for traffic forecasts and financing plans and mandates local jurisdictions to adopt regulations that facilitate ADU construction, including prohibiting limits on the number of ADUs on residentially zoned lots. The bill allows cities and counties to waive or defer fees and taxes for ADUs not used for short-term rentals and establishes that no new restrictive covenants can conflict with the regulations promoting ADU development. This comprehensive approach aims to foster a more inclusive housing development strategy in the state.
