This property is unique.  Located at much sought-after location on Capitol Hill at 517 2nd Street Northeast, it's literally across the street from both the Securities and Exchange Commission and the Thurgood Marshall Federal Courts building.   It's also one block from Union Station and two blocks from the United States Senate and 3 blocks from the Supreme Court. The townhouse was constructed around 1895 as a residence and was occupied by the same family until its current owners purchased it in 1985 and renovated it and converted it to an office building. It has a multiple zoning classification for commercial, retail and residential, almost impossible to find on Capitol Hill. The property is approximately 2700 square feet, with 1800 square feet above ground livable, currently with seven offices and 2 bathrooms, and 900 square feet of partially-finished basement suitable for storage, files, office equipment, etc. The property currently is occupied by a well-known lobby firm that has been there for over three decades.   The lobby firm is flexible about whether it would stay or leave. The owner is asking $1.79 million, close to its DC tax appraised value. This townhouse is ideal for a government relations firm, a trade association, university Washington office or a company or law firm with an SEC or federal litigation practice or an Air B&B.
