Accessory Dwelling Units (ADU) are separate, self-contained dwellings that include living, sleeping, sanitary, and cooking facilities.  An ADU can be located within the principal single-family residential building or in a detached, accessory building on the same lot where the principal single-family dwelling unit is located.  Occupancy of an ADU is restricted to no more than two (2) adults and any number of children, with “adult” being any person eighteen years of age or older.

Requirements for City approval include, but are not limited to, the following:

  • ADUs may be approved in any base zoning district

  • The lot must not be encumbered by covenants that prohibit the construction or use of an ADU.

  • Not more than one ADU is permitted per lot and the total number of dwelling units on the lot, including the ADU, cannot exceed two units.

  • The ADU may be separately metered for electricity, gas, and water.

  • To be approved, the lot where the ADU will be located must provide one parking space, in addition to providing the required number of parking spaces for the existing single-family dwelling and any other uses (two spaces are required for a single-family dwelling).  All required parking must be located on the lot where the ADU is proposed.  Parking spaces may be situated in tandem.  Minimum dimensions for a parking space are 9’ by 18.5’.

  • The total conditioned floor area of the ADU cannot exceed 850 sf. 

  • Lots with an ADU are NOT eligible for a Short-Term Rental permit.

  • A Declaration of Covenants and Restrictions that includes specific restrictions on the property must be approved by the City, executed by the owner, and recorded prior to completion of construction of the ADU.  See DCR Requirements tab for details.
