Accessory Dwelling Units (ADU/DADU)


Accessory dwellings are now allowed in many jurisdictions and can provide either a supplemental income source as a rental unit or an additional living quarters for family or guests. Accessory dwelling units (ADUs) are attached to a primary house, typically located in a lower level or basement. Detached accessory dwelling units (Backyard Cottages or DADUs) are typically located detached from a primary residence, either as they own building or above a garage off an alley. ADUs are limited in size, typically less than 800 to 1,000 square feet. If your property is located within the city of Seattle, the city has posted their requirements for permitting accessory dwelling units here.
