ADU Process

Get started on the right track

Types of ADUs


A detached unit is completely separate from the primary home such as a detached garage or  "pool house." Great privacy advantages. 


An attached unit is attached to the primary home. These can be additions to the current residence or a attached garage. Walls can be added for complete privacy.


Existing spaces such as garages can be converted into separate units.

Interior Conversion

Junior ADU or In-Law units can be converted from existing spaces inside the primary home with partitions.
