Tucked into a sun-warmed hillside in Sonoma's beloved Boyes Hot Springs corridor, 17323 Hillside Avenue offers something the market rarely produces: Two distinct, beautifully appointed cottages on an oak-shaded parcel, framed by terraced gardens and elevated decks. Both residences share a cohesive design language: open floor plans, butcher-block counters, and generous windows that draw in the warm Sonoma light. The mood is rustic-refined, equal parts farmhouse and weekender's retreat. The layout sets the property apart. Unit A lives like a primary home, with two bedrooms and a full bath, vaulted main room, anchored by a treetop-level great room and a wraparound deck with sweeping vineyard hillside views. Unit B is an intimate one-bedroom/one-bath cottage with its own entrance, deck, washer/dryer, kitchen, and privacy. The two fully independent residences are well-suited for hosting extended family, guests, or as a live/work arrangement where both proximity and separation are built in. For buyers considering income potential, the setup supports dual rental streams backed by consistent demand in the Sonoma Valley rental market. The location places the property within easy reach of the Sonoma Plaza, Boyes Hot Springs, and the Highway 12 corridor.
