Rare-find semi-detached 4-family brick building with a finished full basement, private driveway, built-in garage, and mixed zoning (C1-3 & R6B) in the heart of Bay Ridge. The mixed zoning offers excellent flexibility with the potential to convert the building, in whole or in part, to commercial use (subject to architect review and NYC approvals). The 1st-floor duplex offers 2 bedrooms, 2 full bathrooms, plus a finished basement that can provide extra space. The 2nd floor features a spacious 3-bedroom apartment, while the 3rd floor offers 2 one-bedroom apartments. Each unit includes a separate living room, dining room, and kitchen. Situated on an oversized 30×100 ft lot with a 20×55 ft building, this property also features a 10-foot private driveway, built-in garage, and a spacious side yard and backyard. Conveniently located just minutes from the R train, shopping, restaurants, schools, parks, and the Verrazzano-Narrows Bridge. An outstanding opportunity for investors, developers, or owner-occupants seeking strong rental income, future commercial potential, and long-term appreciation in one of Bay Ridge's most desirable neighborhoods. Won't Last!
