Accessory Dwelling Units

An ADU is a separate residential unit providing independent living facilities on a residentially zoned lot that already contains a legally established residential dwelling unit. The key distinction between an ADU and other types of detached structures, such as pool cabanas, is the inclusion of a kitchen in the ADU.

Procedurally, a key aspect of ADUs is that they are approved ministerially through the issuance of building permits only. Discretionary permits for ADUs are prohibited under State law. Because ADUs are not discretionary actions, public notice is not provided as part of the application review process. 


On January 28, 2020, the City Council adopted Ordinance No. 1678-NS to implement new regulations for Accessory Dwelling Units (ADUs) in residential zones. These new regulations were adopted in response to changes in State law that took effect on January 1, 2020.
