75 Broadway, and 105 Chadbourne Avenue, Millbrae, CA 94030

Philip Batlin and Sam Runco of Marcus & Millichap are offering 75 Broadway and 105 Chadbourne Avenue, two adjoining parcels at the corner of Broadway and Chadbourne Avenue in Millbrae, one block from El Camino Real.

The Property

The offering includes an 8 unit apartment building at 105 Chadbourne and a 2 bed, 2 bath single family home at 75 Broadway. All 9 units are occupied, with current rents of $22,821 a month. The combined site is about 12,000 square feet, with 100 feet of frontage on Broadway and 120 feet on Chadbourne, a short walk to downtown Millbrae and minutes to SFO.

Development Opportunity

This is a corner site zoned Residential Focused Mixed Use, close to the Millbrae BART and Caltrain station, one of the busiest transit hubs on the Peninsula. Under SB 79, which took effect July 1, 2026, a site within a quarter mile of a qualifying rail station cannot be held to less than 75 feet of height, 120 units per acre or a 3.5 floor area ratio. On this site, that works out to roughly 33 units before any density bonus, and about 50 units with a 50 percent State Density Bonus. SB 330 and the State Density Bonus Law can also help streamline approvals.

SB 79 eligibility is measured in a straight line from the nearest edge of the parcel to a station pedestrian entrance. Buyers should confirm eligibility with a survey and the City of Millbrae Planning Department. In the meantime, the existing 9 units are fully occupied and producing income.

Offered at $6,500,000. Call Philip Batlin at (415) 625-2189 for the offering memorandum.
