The Charlton Heights Improvement Company, the instrument for developing and marketing the subdivision of Charlton Heights between 1888 and 1892, had its main office at 933 F Street, near its intended clientele. At the time, F Street was a center of commerce in downtown Washington, not far from the Patent Office, the Census Office and the Pension Building, whose employees would have shopped and dined in the stores that lined the street. Also on this block was the old Masonic temple (still standing), a popular venue for meetings and celebrations of the numerous fraternal organizations then in existence. Several of the directors of the Charlton Heights Improvement Company, James Waugh, George Gibson, Chas Duncanson and John Miller, were prominent masons and likely frequented the temple to participate in masonic functions.
As it happens, native Washingtonian and local history enthusiast John De Ferrari features an F Street Stroll in his Streets of Washington blog It gives a detailed description of this section of the city at the turn of the 19th century and is well worth a look.
