NEARLY A CENTURY IN ONE FAMILY. ONE FULL RH LOT. ONE BLOCK FROM THE SAND. 121 28th St is an original 30 x 90 lot of approximately 2,700 SF, running street to street from 28th Street to 28th Place. Held by the same family for nearly a century and passed down between family members, per seller, it is now offered on the open market for the first time. Of approximately 432 RH-zoned parcels between Marine Avenue and Rosecrans, broker research indicates only about 40 still contain a single home on a full lot, and this is currently the only one offered for sale. Buyer to verify. THREE WAYS TO WIN. MOVE IN. The remodeled 1926 bungalow offers 2 bedrooms, 2 baths, central air, quartz counters, a covered front porch with an ocean view down 28th St, a rear deck, and a detached 2-car garage off 28th Pl, keeping parking and rear entry away from the beach-facing side. HOLD IT. A Coastal Zone location with rental potential; short-term rental use may be available through the City program, subject to eligibility, licensing, and buyer verification. BUILD IT. Explore one new single-family home or up to three units, subject to City and Coastal review. Broker analysis indicates approximately 4,585 SF of living area may be possible over three stories under current zoning, plus certain garage and below-grade basement area. Buyer to verify. THE NUMBERS TELL THE STORY. A full-lot duplex on this street sold approximately 11% above asking in about eight days in September 2026, and recent new construction on comparable full RH lots has closed above $10,000,000, per broker research; buyer to verify. THINK BIGGER. The adjoining full lot at 123 28th Street, improved with a seven-unit building and offered separately by the same seller, is also available. Together: approximately 60 feet of frontage by 90 feet deep, roughly 5,400 SF of contiguous Sand Section land, one block from the beach. It took nearly a century to reach the market. Sold as-is. Buyer to independently verify lot size, zoning, buildable area, permitted uses, unit potential, Coastal and short-term rental requirements, and comparable-sale data.
