What Is an ADU or DADU?
An Accessory Dwelling Unit (ADU) is a secondary residential unit built on the same lot as a primary home. ADUs can be attached to the main house, converted from an existing space such as a garage, or built as a Detached Accessory Dwelling Unit (DADU). These units are fully functional homes, typically including a kitchen, bathroom, living area, and private entrance, all built in compliance with local zoning and building codes.
