Masterfully Renovated Tudor

A meticulously renovated vintage Mill Valley Tudor, rich with character and craftsmanship, 83 Sunnyside Avenue is a rare home that feels both distinctive and highly livable. Perfectly positioned on one of Mill Valley’s most beloved streets, this beautifully updated 1929 residence offers 4+ bedrooms, 4 baths, and approximately 3,393 square feet (per architectural plans) in an exceptional close-to-downtown location.
Warm, layered, and full of personality, the home has been thoughtfully remodeled with an exceptional level of detail throughout. Elegant architectural elements include stylish archways, coffered ceilings, classic wainscoting, extensive custom cabinetry, and beautifully crafted millwork. Custom-carved fireplace surrounds — soapstone in the living room and wood in the great room — add artistry and depth, while a sophisticated color palette, abundant windows, and carefully considered sightlines fill the home with natural light and garden views.
Designed for both everyday living and effortless gathering, the main level features inviting living spaces, multiple fireplaces, and a kitchen-great room that opens directly to a brick patio and professionally landscaped garden. The kitchen is anchored by a large custom butcher-block island and is appointed with high-end appliances, generous storage, and a seamless connection to the outdoors.
The primary retreat is a true sanctuary, complete with a fireplace, private balcony, light-filled resort-style bath, and an exceptional walk-in closet with boutique-style storage, generous scale, and a beautifully organized sense of luxury. Two additional upstairs bedrooms share a dual-access en-suite bath, while a main-level bedroom and full bath offer flexibility for guests, an office, or everyday living.
The lower level, with its own separate entrance, creates an ideal au pair, guest, or extended living opportunity. Rich with custom woodwork, the space includes a pub-inspired bar and kitchenette, a full bath, a cozy fireplace, and a comfortable gathering area.
The home’s outdoor space is equally thoughtful, with landscaped areas that feel private, usable, and beautifully integrated into the property. Additional amenities include a one-car garage with ample storage, off-street parking, AC and a whole-house fan, an EV charger, an owned solar system, and two Tesla backup batteries.
Just two blocks from downtown Mill Valley and two blocks from Boyle Park, 83 Sunnyside offers the best of the Mill Valley lifestyle — cafés, shops, restaurants, parks, schools, and Mt. Tam trails all moments away. With its vintage architecture, artistic spirit, south-facing light, exceptional craftsmanship, and coveted Sunnyside address, this is a home with history, heart, and an unmistakable sense of place.
