Bill > HB2126

This bill authorizes the development of detached accessory dwelling units (ADUs) in rural areas of Washington state, even where otherwise prohibited by a county's comprehensive plan, countywide planning policy, or multicounty planning policy. The bill establishes a set of requirements that counties must follow in order to allow these rural detached ADUs, including regulations related to water usage, sewage systems, and size limitations. The bill also specifies that population growth from these rural detached ADUs cannot be counted towards a county's rural or urban growth targets, and requires counties that authorize these rural detached ADUs to update their comprehensive plans and countywide or multicounty planning policies to allow for them.
