About This Home

As of May 2026

Don't miss this midcentury gem in the heart of Scott Valley. This light-filled residence was the childhood home of two sisters who still own the property, and it was custom built by their parents in 1965. It's a spacious, split-level home with an elegant entrance foyer that leads to a grand living room with vaulted ceilings and a dramatic fireplace. Also on the main level is the kitchen which opens to a comfortable family room with a second fireplace and access to the lush backyard. The lower level also includes a formal dining room, a guest bedroom, and a full bath. Up a short staircase are 3 more bedrooms and 2 baths, including the primary suite with an office/lounging nook, a walk-in closet with built-ins, and sliding doors leading to a private outdoor patio. The additional bedrooms are well-sized with windows that take in the valley views. The 2-car garage has a separate work or hobby room'' with a window. Recent improvements include a brand new roof and a sewer lateral. Other upgrades include white oak wood flooring throughout the main level, fresh paint inside and out, updated lighting and hardware, and other cosmetic improvements. The home is set back and up from the street on this large lot. The backyard is landscaped with attractive native plants and has patios and flat space for outdoor entertaining, dining, and play. All this in a great location in the flats of Scott Valley, close to Edna Maguire Elementary School, The Scott Valley Swim and Tennis Club, The Mill Valley Community Center and access to some of the area's best biking/walk paths, open space, and scenic trails. NOTE: The neighborhood HOA is a voluntary organization and $50 annual dues are not mandatory.
