Sewer Connection Reporting Requirements for ADUs and DADUs
SDCI is now reporting new Accessory Dwelling Unit (ADUs) and Detached Accessory Dwelling Unit (DADUs) permits to King County for the purpose of capacity charges. We are required by code and our agreement with King County to report all new sewer connections to King County. Title 28 of the King County Code requires that we report all new units to the King County Wastewater Treatment Division.
