559 Marin Avenue, Mill Valley
A Rare Mill Valley Retreat Offering Space, Style, and Endless Possibility

Tucked into the hills of Mill Valley’s sought-after Tam Junction neighborhood, 559 Marin Avenue is a beautifully updated 3-bedroom, 2-bath retreat offering the perfect balance of comfort, functionality, and opportunity. Set on an expansive 11,250 sq ft street-to-street lot, this approximately 1,491 sq ft home provides a seamless indoor-outdoor lifestyle and the flexibility to grow, work, create, and unwind—all within minutes of hiking trails, coastal adventures, and local conveniences.

Renovated with Care and Style
Thoughtfully renovated, the home features a bright, open layout with refinished flooring throughout, and a freshly updated kitchen with modern appliances, cabinetry, and finishes. Both bathrooms have been tastefully remodeled to blend timeless elegance with daily practicality. Sunlight fills the living spaces, creating a warm, inviting atmosphere that flows effortlessly into the outdoors.

Flexible Living Spaces to Fit Your Life
In addition to the main home, a detached bonus structure offers an ideal space for a private office, art studio, or guest retreat—perfect for remote work, creative pursuits, or quiet reflection. The basement level provides even more flexibility, with a separate laundry room, ample storage, and a bonus room that could serve as an additional office, gym, or playroom.

Outdoor Living at Its Best
Step outside and enjoy the large backyard, a sunny, serene haven for gardening, entertaining, or relaxing under the trees. The oversized lot offers room to dream—whether it’s building an accessory dwelling unit (ADU), exploring a lot split, or expanding the home (all subject to county approval). A one-car carport and additional off-street parking make everyday living easy.
