This property offers far more than meets the eye. Its R-L (Low Density Residential) zoning opens the door to a rare range of future development possibilities, including SB9 lot split potential which may allow for up to two lots with the possibility of two units per lot along with ADU/JADU opportunities, creating an exceptional canvas for expansion, multi-generational living, or long-term investment (buyer to verify). Just blocks from the iconic Sonoma Plaza, this charming turn-of-the-century cottage pairs immediate lifestyle appeal with remarkable upside. Rich with vintage character and original wood floors, the 3-bedroom, 1.5-bath residence offers great bones now thoughtfully enhanced with recent roof, electrical, HVAC, and comprehensive interior/exterior paint upgrades. Designed for both relaxed living and memorable entertaining, a beautifully covered indoor-outdoor dining pavilion seamlessly connects the main residence to the expansive oversized garage currently transformed into a vibrant flex space with game room, lounge, and gathering areas that flow effortlessly to additional outdoor entertaining spaces, including a fire pit retreat. Whether enjoyed as-is or reimagined over time, the property offers an uncommon blend of charm, versatility, and future potential. Whether envisioned as a thoughtfully updated in-town Sonoma residence, a strategic development opportunity, or a dynamic live-investment hold, this is a uniquely flexible offering in one of Sonoma's most coveted downtown locations.
