Why is there a law that no building can be over 13 stories tall in dc?

The law that limits building heights in Washington, D.C., to 13 stories is primarily rooted in the Height of Buildings Act of 1910. This legislation was enacted to preserve the city's skyline and ensure that no building would overshadow important landmarks, particularly the U.S. Capitol. The law aims to maintain aesthetic harmony and prevent overcrowding, while also preserving the character of the city as a national capital. Additionally, concerns about light, air, and the overall urban environment played a significant role in establishing these height restrictions.
