Under FAA regulations (FAR 91.119), which remain the standard in 2026, the minimum altitude a plane can fly over your house depends on the density of the area. Over congested areas (cities or towns), aircraft must maintain an altitude of at least 1,000 feet above the highest obstacle within a 2,000-foot horizontal radius. In non-congested or rural areas, the minimum is 500 feet above the surface or any person, vessel, or structure. The most important exception is during takeoff and landing; planes are legally allowed to fly much lower as they follow the established approach or departure paths for a nearby airport. Helicopters have even more flexibility and may fly below these minimums as long as they operate without "undue hazard" to people or property on the ground. If you feel a plane is flying dangerously low outside of an airport zone, you can report the tail number to your local Flight Standards District Office, though "low" to the naked eye is often well within the legal 1,000-foot limit.
