List of tallest structures in the United States

The height of structures in the United States has been poorly documented. However, the data is a matter of public record, appearing in documents maintained by the Federal Aviation Administration (FAA) and Federal Communications Commission (FCC).

This list is populated heavily by antenna masts. The engineering aspects of super-tall masts are highly specialized. Only four companies erect the majority of such structures: Doty Moore Tower Services (Cedar Hill, Texas); Kline Towers (Columbia, South Carolina); LeBlanc Royal Telecom (Oakville, Ontario); and Stainless Inc. (North Wales, Pennsylvania). The design and construction are largely governed by RS222E Electronic Industries Alliance standards. A 1,000-foot (300 m) tall mast costs between $0.7 and $1.1 million to build, while a 2,000-foot (610 m) tall mast costs $2.4 to $4 million. Prices generally vary depending on tower capacity and wind loading specifications.

A common misperception is that landmarks such as the Stratosphere Tower are the tallest United States structures, but they are in fact the tallest buildings. Likewise, Taipei 101 was often misrepresented as the world's tallest structure (although it was the tallest occupied building, before the certification of Dubai's Burj Khalifa as such), but in fact is far eclipsed by antenna towers in over a dozen states in the United States and in other countries.

In the United States, the FAA and the FCC must approve all towers exceeding 200 feet (61 m) in height. Furthermore, it is very difficult to get permission for structures over 2,000 feet (610 m) tall. The FCC presumes them to be inconsistent with the public interest, while the FAA presumes them to be a hazard to air navigation, resulting in poor airspace usage. A significant burden of proof is placed on the applicant to show that such a structure is in the public's best interests. Only when both agencies have resolved all legal, safety, and management concerns is such an application approved.

Since 1978, the United States has maintained 11 tethered aerostats sites along the southern borders. These balloons rise to 18,000 feet (5,500 m), carrying radar units for drug interdiction purposes. However, since the balloons are aided by buoyancy and are not permanent, they are not considered true structures.

When used for television broadcasts by its former owner, Multimedia, Inc. (former licensee of WBIR-TV, Knoxville) it was shielded by mountains from the audience in the western Knoxville suburbs such as Farragut, Oak Ridge, and Oliver Springs. This tower was built because the owners of WBIR-TV could not obtain land atop nearby House Mountain, because the only land suitable for a television tower base on the mountain had been purchased by the station's main competitor WATE-TV, Knoxville. When completed, it was, for a short time the tallest man-made structure on Earth.
