About ADUs

An ADU must include permanent living, sleeping, eating, cooking, and sanitation provisions on lots that are zoned to allow single-family or multi-family residential uses that include an existing or proposed dwelling. An ADU can also include an efficiency unit, or a manufactured home (on a permanent foundation only).

Here are a few basic ADU variations:

Detached: The unit is separated from the primary structure.

Attached: The unit is attached to the primary structure.
