About This Home

As of March 2025

Located in the heart of Sonoma County's wine country, 1633 Willowside Rd offers a rare opportunity to own 3 acres of flat, usable land with stunning vineyard views and incredible sunsets. This gated property features a 3-bedroom, 2-bathroom home with a spacious circular driveway for easy access and ample parking. A large detached garage/shop provides plenty of space for storage, a workshop, or possible ADU conversion. With room to grow, the property offers endless possibilities, from cosmetic remodeling to expanding the footprint of the current home to adding an ADU. In 2020, the sellers completed and permitted a 1 BD septic design for a future ADU. If you're looking for an incredible piece of property in one of Sonoma County's most desirable areas that combines location, privacy, space and potential, this is one property you don't want to miss.
