Types of ADUs

There are two types of ADUs: standard ADUs and Junior ADUs [also known as JADUs]. There is also a third option, the “Efficiency Kitchen Alternative”.

Standard ADUs involve creation of a new independent living unit with separate exterior entrance from a primary single- or multifamily dwelling. There are three ways that standard ADUs can be created on a property:

  1. Conversion: Convert part of the existing home, garage or accessory structure; or
  2. New Construction – Attached: Build a new addition to the existing home or attached garage; or
  3. New Construction – Detached: Build a new, free-standing dwelling unit on the property or build an addition to an existing detached garage or accessory structure.

JADUs involve creation of a new living unit, maximum 500 square feet, converted from within the walls of a single-family dwelling, including attached garages and other nonliving spaces. JADUs have a kitchen and a separate exterior entrance. A JADU may have interior access to the primary dwelling but this is not required. Bathrooms can be separate or shared with the primary dwelling.
