Flexible 2900 sq ft corner property near the historic main gate of the Washington Navy Yard and just off the bustling 8th Street/Barracks Row corridor - available for the first time in over 40 years! According to a history of the property, this brick building with the separate addresses of 929 and 931 Potomac Avenue SE was built probably in the 1840s - and since then it has had a fascinating dual commercial and residential history: retail grocery/bakery stores, several residential apartments, offices of a technology company and large single family home. Most recently the combined spaces have been the personal residence of its current owner with a 2,522 sq ft floor plan of 5+ bedrooms, 2.5 bathrooms on three floors and with a 375 sq ft utility basement. 929/931 Potomac sits on a large corner 1621 sq ft lot. Per tax records, the zoning has commercial PDR-1 overlay, and the owner's current tax use code is 011 (residential single family row), which presents a wide range of possible future opportunities in one of the most historic parts of Capitol Hill/Navy Yard. Rare opportunity to transform 929/931 Potomac Ave SE as you desire near the bustling Barracks Row corridor, and adjacent to the Marine Barracks, the US Transportation Department, National's Stadium, and the vibrant Navy Yard community. Across the street, don't miss the pretty and newly redone park, community veggie gardens, and playground. Equidistant to Eastern Market + Navy Yard METROs. Walk Score 90, Bike Score 91.
