306 Bella Vista Avenue sits in one of Belvedere's most sought-after locations, with sweeping views of San Francisco Bay, Angel Island, Corinthian Island, and the Tiburon hills. Originally built in 1904 and well updated over the years, the home offers 3,910 square feet across a flexible 5+BR, 3.5BA layout that works equally well for entertaining or everyday living. The main level features hardwood floors, a double-sided fireplace dividing the living and dining areas accented with coffered ceilings, and direct access to a large deck where the views are front and center. The kitchen is well appointed with Zimbabwe honed granite countertops, stainless Viking appliances, and a casual dining area for daily use. A legal one-bedroom guest unit on the lower level with its own kitchen and full bathroom gives the home real flexibility, whether used for family, a home office, or rental income. The primary suite on the upper level captures the best views in the house, with convenient carport access. Three-car covered carport parking is a genuine rarity in this neighborhood. A short walk to Belvedere's waterfront paths and just minutes to downtown Tiburon's shops, restaurants, and ferry, this is a well-positioned Marin address with a lot to offer.
