Accessory Dwelling Units (ADUs)

On ADU Tuesdays, we offer Express Plan  Review for ADU projects.

 On Dec. 17, 2019, the City Council approved easing ADU requirements to align with new state laws. The ADU Universal Checklist and website reflect these changes.

Accessory dwelling units — also called ADUs, secondary units, or granny flats — are small living units, including a kitchen and bathroom, on a property that has one single-family home.

There are many benefits to ADUs, including that they:

  • Create more affordable housing for our community, family members, or disabled persons;
  • Provide an income opportunity for homeowners;
  • Promote infill development; and
  • Encourage the use of public transportation.
