Accessory Dwelling Unit Information
An ACCESSORY DWELLING UNIT is an independent dwelling unit located on the same lot as an existing single-family residential structure. An Accessory Dwelling Unit (ADU) provides complete living, sleeping, eating, cooking and sanitation facilities.
ADUs can help improve housing affordability and diversify a community’s housing stock without changing the physical character of a neighborhood.
ACCESSORY DWELLING UNIT TYPES
Accessory Dwelling Units come in a number of forms including:
- Detached from the primary residential structure
- Attached to the primary residential structure
Some utilize existing spaces including garage or basement conversion.
Other options include creating new space on the property through new construction.
