Methodology

Non-freestanding structures, observational towers, and communication towers are excluded (North Dakota boasts the largest guyed mast structure in the world), as are antennae extending from the structure top.

Statistics

• The height of the tallest building in the U.S. (Willis Tower, in Chicago), at 1451 feet (442 m), is more than the combined heights of the tallest buildings in Wyoming, Vermont, Maine, South Dakota, North Dakota, and Idaho.

• • Four of the buildings are attributed to JPMorgan Chase. Three each are named for Bank of America and US Bancorp, with two for Wells Fargo.
  • 6 include part of nation's name in their title (the 3 Bank of America buildings and the 3 US Bank buildings). In addition, 2 use the word National and 1 uses the word Republic.
  • 5 include the state of location in their title.
  • 5 include the city of location in their title. In addition, 2 (Delaware and Washington) include a different metropolitan city in their title.
• 18 are in the state's capital city.
• Both Portland, Oregon and Portland, Maine sport their respective states' tallest building.
• 40 are in the state's largest city. 6 are in the second largest city (Florida, New Jersey, North Dakota, Ohio, Oklahoma, and Tennessee). 2 are in the third largest city (Alabama and Connecticut). 1 is in the fourth largest city (Mississippi). 1 is in the fifth largest city (Vermont). Note that, although the building locations are indicated by municipal area, the city sizes are defined by population within the city borders. For more info, see List of U.S. states' largest cities.

Notes

A. City is here defined by the broader definition of urbanized area. See urban area for more information.

B. Year completed

C. Previously named the Bank One Center.

D. The Cathedral of the Immaculate Conception, also in Portland, is a taller structure, but not inhabited at the higher levels, and therefore does not fit the criteria for tallest buildings.

E. The Stratosphere Tower is the largest tower in Nevada and west of the Mississippi River in the United States. However, because the structure is not fully habitable, it is excluded from this list. Please see the Methodology for further information.

F. Previously held by the Zip Feed Mill until its demolition in 2005. Qwest Tower is currently uncertified, and some dispute has been noted suggesting St. Joseph's Cathedral (also in Sioux Falls) may actually be taller.
