Quintessential vintage Mill Valley farmhouse set on a huge 11,750+- sq ft lot with substantially level areas of yard and panoramic views of the Bay! This home is a fixer with incredible potential. It’s an amazing opportunity. It could be lovingly restored or someone might want to tear it down and build a new home and ADU. Set in Tam Valley’s Almonte neighborhood, 238 California is one of Mill Valley’s well-known historic farmhouses that everyone has driven by at one time or another. This is a special property defined as much by its setting as by its story. Framed by mature Monterey Cypress trees, the home captures sweeping views of the Bay and Sausalito, with natural light pouring through multi-paned windows and a balcony positioned to take in the scenery. The main residence carries the warmth, charm, and character of an earlier era that’s rare to find, with hardwood floors, a living room fireplace, formal dining room, and a kitchen lined with large windows overlooking the views. Upstairs, three bedrooms offer walk-in closets and outlooks toward nature. The lower level includes storage, laundry, and an in-law suite complete with its own kitchen and full bath, creating flexibility within the existing footprint. An additional wing built with a mid-century vibe expands the layout further, could be a master suite but currently shows as a family room with fireplace, office space, full bath, and access to a spacious back deck that opens to the substantially level yard. Whether envisioned as a full restoration of a historic Mill Valley farmhouse or a new chapter entirely, this is a rare opportunity to reimagine a well-positioned property in one of Southern Marin’s most desirable locations. Living in the Almonte neighborhood of Tam Valley offers a rare balance of privacy, nature, and accessibility. Surrounded by open space yet close to Mill Valley and San Francisco, days can begin enjoying Bay views from your home, followed by an easy commute or time spent on nearby coastal trails. Known for its relaxed community feel and close connection to both Mill Valley and Sausalito, Tam Valley places beaches, trailheads, and local favorites just minutes away. For those seeking a property with history, presence, and exceptional potential, 238 California represents an opportunity to shape something truly special in one of Marin’s most coveted settings.
