Accessory Dwelling Unit (ADU)

An Accessory Dwelling Unit (ADU)  is a dwelling unit on a residential lot that provides complete independent living facilities for one or more persons with a separate exterior entrance to a separate living space that includes permanent provisions for living, sleeping, eating, cooking, and sanitation independent of the main dwelling.  An ADU is subordinate to the primary dwelling.

An ADU is permitted in the Agricultural (A) Zone District. 

Purpose of an ADU

  • Provide a mix of housing
  • Provide a broader range of accessible and more affordable housing

Certificate of Exception

Accessory dwelling units (ADUs) constructed prior to October 2023 do not qualify as non-conforming uses because ADUs were not an allowed use in any zone district. On or before December 29, 2023, any person who has constructed an ADU in any zone district may apply to the Community Development Department for a Certificate of Exception.  This Certificate of Exception will allow the ADU to continue if the ADU meets certain building codes and site standards.
