The ADU Center

We support homeowners in building ADUs through providing resources and offering support throughout the process. An ADU is a flexible space that grows with your family. From space for your loved ones to supporting the community and building your retirement through renting, your ADU will grow with you. By building an ADU, you’re investing in the future of your community. ADUs not only benefit homeowners, but also help the community as well. Building ADUs helps to address the housing challenges in California, and ADUs often provide homes for school teachers, firefighters, and other community members who otherwise may have to commute long distances from outside Napa, Sonoma and Marin to find a home they can afford.
