Overview

This charming 1923 triplex sits proudly on a spacious 8,000+ sq ft corner lot just a short distance from Mills College. With quick access to HWY 580/13 and public transit, the location is ideal for commuters, students, and anyone seeking easy access to the greater Bay Area. Each unit offers vintage charm with original hardwood floors, classic Wedgewood stoves, cozy fireplaces, and the convenience of in-unit washer and dryers. The property includes three garages, two currently in use and one with potential to be converted into an additional unit (buyer to verify), creating more flexibility and income opportunity. Out back, the gated yard is currently set up as a shared communal space, but could easily be divided into private outdoor areas for each unit. Whether you’re an investor, a house-hacker, or someone looking for long-term upside, this is a rare chance to own a character-filled property with options.
