Accessory Dwelling Units (ADUs)

Are you interested in building an ADU on your property?

ADUs, or Accessory Dwelling Units, are allowed in Yountville.

If you're interested in building an ADU on your property, please see the Town's ADU flyer (PDF), which provides information on building allowances for ADUs.

Please also visit Napa Sonoma ADU. This site provides information on different kinds of ADUs, costs, and the permitting and building process for ADUs in Napa and Sonoma counties.

You are also welcome to call the Planning and Building Department to speak to a planner about your ADU project. You can reach us at 707-944-8851.
