What drives Capitol Heights’ History grade
On its age, its old homes and the National Register, Capitol Heights is more historic than 33% of U.S. towns, #132 of 261 in Maryland. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Capitol Heights’ overall grade.
Few Maryland towns list much on the Register (a typical Maryland town has 0.9 per 10,000 residents, the U.S. 2.4), so Capitol Heights’ 0.0 sits below most of its state (20% of Maryland towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share is a Census survey estimate (±8.7 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1910.

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.
