Thinking about an ADU? Schedule your personal consultation

Join us for a learning adventure!

We are a nonprofit dedicated to educating homeowners in Napa and Sonoma Counties about how to plan, permit, and build Accessory Dwelling Units —and how to rent out your ADU, if you choose to do so.

Register below for our 100% free upcoming ADU webinars and events!

We know that some homeowners are interested in virtual ADU tours. For now, we recommend you check out our ADU stories for inspiration and a peek into real-world ADUs.
