Two blocks to Windansea. Two units. Room to grow. This 1962 duplex sits on a 6,577 sq ft RM-1-1 lot in La Jolla's Beach Barber Tract, one of the few coastal pockets where a buyer can live, rent, or build. The front unit (643) offers 3 bedrooms, 1 bath, a private front yard, a 1-car garage with laundry hookups, and an attached storage room. The back unit (643B) has 2 bedrooms, 1 bath, and a large private backyard. The property shows its age but is in great, livable condition. Live in one unit and rent the other, keep both as income, or plan for the future. Zoning may allow 2-3 additional units by maximizing ADUs, making this a strong candidate for investors and builders looking to unlock the site's full potential. Location does the rest. Walk Score of 83, with Windansea Beach, Neptune Park, and the La Jolla Strand steps away. Cafes, restaurants, and shops along La Jolla Blvd are a short stroll, with the Village and Bird Rock minutes away. Bus Route 30 stops one block away. Within the San Diego Unified School District, near highly rated La Jolla High School, Muirlands Middle School, and La Jolla Elementary. Opportunities this close to the sand, with this much flexibility, do not come up often. Buyer to verify all square footage, zoning, school assignments, and development potential with the City of San Diego.
