1. What are the setback requirements for an ADU?

A detached ADU must have side and rear setbacks of at least four feet. Otherwise, setbacks applicable to other structures on the parcel apply.  See City Code Section 6.85.030.A.1 for residential setback requirements.

2. Are there architectural style or design criteria for an ADU?

ADUs must be designed and constructed to architecturally and aesthetically match the existing single-family dwelling in terms of exterior materials, colors, building elements, structure mass and roof pitch.

3. Is parking required for an ADU?

An ADU must provide one parking space in addition to parking required for the primary dwelling. The parking space may be covered or uncovered and can be provided on an existing paved driveway. However, in the following instances, no additional parking space is required:

c.    The accessory dwelling unit is part of the proposed or existing primary residence or an accessory structure.

d.    When on-street parking permits are required but not offered to the occupant of the accessory dwelling unit.

e.    When there is a designated car share vehicle parking space located within one block of the accessory dwelling unit.

When a garage, carport, or covered parking structure providing required parking for the primary residence or residences is demolished to allow for the construction of an ADU or is converted to an ADU, those parking spaces are not required to be replaced.

The 2019 Energy Code PV system prescriptive requirements under Section 150.1(c)14 apply only to newly constructed detached accessory dwelling units (ADUs). Exceptions from this requirement may be granted based on limited solar exposure or high snow load.  See the City Solar Photovoltaic Exceptions handout for more information.
