Only up to 500 feet (or 360 over the tallest building in rural areas). In the United States, the Federal Aviation Administration (FAA) has the sole authority to control all "publicly owned" airspace, exclusively determining the rules and requirements for its use.[2] Specifically, the Federal Aviation Act provides that: "The United States Government has exclusive sovereignty of airspace of the United States",[3] but not all the airspace is "possessed" by the United States. For non-public airspace, Congress has provided authority for the FAA to purchase this non-public airspace near airports to accommodate planes taking off and landing.[4] The "navigable airspace" in which the public has a right of transit without affecting a landowners property rights has been set at the height of 500 ft in urban or suburban areas,[5] and 360 feet above the surface or tallest structure in rural areas.[6] No government would allow property owners the rights to space above their property "into infinity" otherwise air travel would be impossible, because airplanes would "trespass" constantly.
