Establishes limitations on detached accessory dwelling units outside urban growth areas in Washington.

The bill sets limitations on detached accessory dwelling units outside urban growth areas in Washington. It requires counties to track and report the number of such units annually, limits the number of permits to one per parcel, and mandates that the units be within 150 feet of the principal unit and use the same driveway. The units must comply with water supply and sewage system requirements, and their gross floor area cannot exceed that of the principal unit. The bill also updates the comprehensive land use plan to account for these units and limits amendments to every five years.
