This list of tallest buildings in Washington, D. The tallest structure in the city, excluding radio towers, is the Washington Monument , which rises feet m and was completed in The structure, however, is not generally considered a high-rise building as it does not have successive floors that can be occupied.

The second-tallest building in Washington is the Old Post Office Building , which is feet 96 m high. The third-tallest building in the city is the Washington National Cathedral , which rises feet 92 m above grade. The cathedral is built on high ground known as Mount St. Alban, feet m above sea level, which makes the central tower the "highest" point in the District. As of November , there are completed high-rises in the city.
Washington's history of high-rises began with the completion in of The Cairo, an apartment building, which is considered to be the city's first high-rise.
The building rises feet 50 m and 14 floors. Washington went through an early high-rise construction boom from the late s to the mids, during which time the Old Post Office Building and the Federal Triangle were built. The city then experienced a major building boom from the early s to the late s, during which the city saw the completion of 31 of its 48 tallest buildings, including One Franklin Square and Eleventh Street.
However, although the city is home to several high-rises, none are considered to be genuine " skyscrapers "; only two completed buildings surpass feet 61 m. The height of buildings in Washington is limited by the Height of Buildings Act. The original Act was passed by Congress in in response to the construction of the Cairo Hotel, which is much taller than the majority of buildings in the city. The original act restricted the heights of any type of building in the city to be no higher than feet 34 m , 90 feet 27 m for residential buildings.
In , the 61st United States Congress enacted a new law which raised the overall building height limit to feet 40 m , but restricted building heights to the width of the adjacent street or avenue plus 20 feet 6. However, building heights are measured from the sidewalk or curb to the edge of the roof.
Architectural embellishments, mechanical rooms, and common rooftop structures may be exempted from the overall height limit, provided they are set back from the roof line.
The heights of buildings listed here may therefore exceed the general height limit as measured for the purpose of the city's zoning laws. In modern times the skyline remains low and sprawling, keeping with Thomas Jefferson 's wishes to make Washington an "American Paris " with "low and convenient" buildings on "light and airy" streets. Washington's height restriction, however, has been assailed as one of the primary reasons why the city has inflated rents, limited affordable housing, and traffic problems as a result of urban sprawl.
