All districts
Accessory dwellings are a listed accessory use: the Section 5.2.6 table controls which districts allow them, and Section 5.2.7.A sets the standards: maximum one accessory dwelling per lot; on a single-family residential lot the owner must be a permanent occupant of the premises; the accessory dwelling's building footprint may not exceed 50 percent of the principal building's footprint; an existing accessory structure may be converted if the conversion does not increase any dimensional nonconformity; parking is one space per unit under Section 10.2.3. The 5.2.6 table's district-by-district permission marks are graphical in the published ordinance, so confirm the district column with Planning before relying on an ADU design.
