How is building height measured?
Maximum building height is measured as the vertical distance from finished grade at each point around the perimeter of the building to the uppermost portion of the roof. Building height is typically shown for each respective cross‑slope section of the building.
What are the standards for an Accessory Dwelling Unit (ADU)?
An Accessory dwelling unit is an attached or a detached residential which provides complete, independent living facilities for one or more persons, located on a lot containing a single-family dwelling as the principal building. It includes permanent provisions for living, sleeping, cooking, eating, and sanitation. An ADU generally takes three forms:
- Detached: The unit is separated from the primary structure
- Attached: The unit is attached to the primary structure
- Interior: The unit is comprised of existing space within the primary residence or an accessory structure (i.e., a guest bedroom is converted into an independent living unit).
Note: An ADU may consist of an efficiency unit, as defined in Section 17958.1 of the State Health and Safety Code (minimum of 150 sq. ft.); or a manufactured home, as defined in Section 18007 of the Health and Safety Code.
Accessory dwelling units are permitted within all single family residential zones and within multi-family residential zones.
ADUs applications meeting ministerial standards can be approved with a building permit. Ministerial standards do not require discretionary review (i.e., Conditional Use Permits and/or Single-family Design Review). The application requirements and standards for ADUs vary by the type of unit. Additional information is provided in the City’s ADU Information Page.
