In January 2017, Sonoma County adopted an ordinance to encourage the creation of more affordable housing. This ordinance aligns with recent State legislation and helps address the County’s housing crisis by encouraging the construction of Accessory Dwelling Units and Junior Accessory Dwelling Units.
An Accessory Dwelling Unit is a small permanent home that may be established in addition to the main dwelling on a parcel zoned for residential use. A Junior Accessory Dwelling Unit is a very small living unit within a single-family dwelling. It’s 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. Transient occupancy, including vacation rentals, is prohibited in Junior Units and Accessory Dwelling Units.
Accessory Units and Junior Units provide an opportunity for homeowners to quickly and inexpensively create an additional living unit within their home. They provide rental housing stock and provide homeowners with additional financial security.
