Accessory Dwelling Unit (ADU)

Accessory dwelling units are smaller, independent second dwellings on a single-family lot. They have their own living, bathroom, and kitchen space. Homeowners often build accessory dwelling units to house a relative, office or studio space, or to bring in additional income by renting the space. Accessory dwelling units can take multiple forms: they can be located within or attached to a main dwelling, like a basement apartment or an addition, or they can be within a new or existing detached structure.
