In 1904, Washington, D.C., was growing by leaps and bounds. The overcrowding and the improved public transportation made the idea of living on the outskirts increasingly appealing to people looking for housing. Recognizing the opportunity, Baltimore resident Otway B. Zantzinger acquired 400 hilly acres just beyond the eastern corner of the District of Columbia. He divided the tract into 4,000 lots and began to sell them at prices ranging from $20 to $150 each. He advertised a picturesque view of Washington, D.C., a proposed electric railway, drinking water from crystal-clear springs, nothing down and a dollar a month, no interest, no landlords, and, in the custom and vernacular of the times, "no colored people." Many buyers bought two lots in this haven that was to become Capitol Heights.
While awaiting their "proposed electric railway," commuters to the city could walk about a mile (often through mud) to the District Line station at what is now Seat Pleasant and board a rail car into Washington, DC.
the absence of paved roads, sidewalks, street lights, and other public services, including the electric railway, began to cast a pall over Zantzinger's vision of bliss. In 1910, the approximately 200 householders voted to incorporate their community as Capitol Heights.
