Some homes check every box. This one creates an entirely new list. Set along one of Downtown Petaluma's most coveted stretches of D Street, this rare 1920s residence has been exquisitely reimagined for modern living. Behind its classic brick facade is a sophisticated blend of historic character, exceptional design, and contemporary luxury creating a home that feels both timeless and entirely one-of-a-kind. From the moment you arrive, beautifully curated landscaping and a gated iron entry make a memorable first impression. Inside, a formal foyer opens to a light-filled living room where soaring 10-foot ceilings, generous proportions, and thoughtful architectural details set the tone. At the heart of the home, the chef's kitchen is equal parts statement and function, featuring marble countertops, a La Cornue range, farmhouse sink, floating shelves, abundant storage, and plenty of room to gather. Just beyond, the intimate dining room opens through retractable glass doors to the patio and landscaped backyard, creating a seamless indoor-outdoor connection designed for entertaining, long dinners, and relaxed Wine Country living. Upstairs, the primary suite offers a private retreat filled with natural light, two closets including a walk-in and a spa-inspired bath with an oversized shower, freestanding clawfoot tub, and dual sinks. Two additional bedrooms share a Jack-and-Jill bath, while the main level includes a flexible laundry room or office and guest bath. The outdoor spaces are equally impressive, with beautifully designed grounds, a generous entertaining patio, and room for a future pool. A detached ADU with a full kitchen and bath adds yet another layer of versatility ideal for guests, extended living, a private workspace, or additional flexibility. And then there's the location. Historic Downtown Petaluma, acclaimed restaurants, cafes, boutiques, the cinema, waterfront, and SMART Train are all just blocks away, placing some of the city's most loved destinations within exceptionally close proximity. More than a beautiful home in a remarkable location, 853 D Street is a rare opportunity to experience Petaluma in an entirely different way. Distinctive architecture, elevated interiors, beautiful outdoor living, a detached ADU, and an exceptional Downtown setting come together in a property unlike anything else on the market.
