Accessory Dwelling Unit Survey

Published:  November 2, 2018

The County of Sonoma and partnering cities want your input on potential barriers and incentives for building accessory dwelling units and/or junior accessory dwelling units. Thank you for taking the time to fill out this survey to inform our efforts to increase housing in Sonoma County.

What are ADUs and JADUs?

Accessory dwelling units (ADUs) are backyard cottages of up to 1,200 square feet. An ADU is a small permanent home that may be established in addition to the main dwelling on a parcel zoned for residential use. ADUs may be attached or detached from the main dwelling.

Junior Accessory Dwelling Units (JADUs) are very small living units (up to 500 square feet) created out of a bedroom within an existing single family home. A JADU is created by adding an efficiency kitchen and exterior door to an existing, legal bedroom. It may include a bathroom or may share a bathroom with the house. A residential property can have both an ADU and a JADU if requirements (septic, etc.) can be met.
