An ADU is an Accessory Dwelling Unit with complete independent living facilities for one or more persons and has a few variations:
- Detached: The unit is separated from the primary structure
- Attached: The unit is attached to the primary structure
- Converted Existing Space: Space (e.g., master bedroom, attached garage, storage area, or similar use, or an accessory structure) on the lot of the primary residence that is converted into an independent living unit.
- Junior Accessory Dwelling Unit (JADU): A specific type of conversion of existing space that is contained entirely within an existing or proposed single-family residence.
