  Charming 4BD/2BA, approx. 2,000 sq ft on a generous .34-acre lot with pool. Flexible two-story layout with a private upstairs bed/bath suite, main-level bedrooms and living areas, ready for a buyer’s personal updates. Great opportunity in a peaceful Sonoma neighborhood with tons of potential.

Step into 405 Walnut Ave, a lovingly cared-for 4-bedroom, 2-bath home offering approximately 2,000 sq ft of inviting living space on a generous .34-acre lot with a new roof. Tucked into a peaceful Sonoma neighborhood, this home has been in the same family since 1982, a place where memories were made, traditions were kept, and pride of ownership shines. Thoughtfully expanded with a custom addition by the longtime owner, the home features a flexible two-story layout. One bedroom and one bathroom are located upstairs, creating a private suite for guests or the perfect work-from-home hideaway. The remaining bedrooms and main living spaces sit comfortably on the main floor, filled with natural light and designed for easy everyday living. The expansive backyard is the true heart of the property. With a pool and plenty of room to entertain, garden, or simply unwind, this .34-acre lot offers the kind of space that's hard to come by in Sonoma. Homes with this combination of history, warmth, and opportunity don't come to market often. 405 Walnut Ave is ready for its next chapter.
