Height of Buildings Act of 1910

The Height of Buildings Act of 1910 was an Act of Congress passed by the 61st United States Congress on June 1, 1910, to limit the height of buildings in the District of Columbia, amending the Height of Buildings Act of 1899. The new height restriction law was more comprehensive than the previous law, and generally restricts building heights along residential streets to 90 feet (27 m), and along commercial corridors to the width of the right-of-way of the street or avenue on which a building fronts, or a maximum of 130 feet (40 m), whichever is shorter.
