Under 49 U.S.C. § 40103, the FAA has exclusive sovereignty over navigable airspace. This authority preempts most local and state attempts to ban drones outright. No federal statute, however, specifically prohibits a drone from flying over private property. The FAA's UAS regulations focus on registration, airspace authorization, and operational rules (below 400 feet AGL, visual line of sight, no flying over people without a waiver), not on property rights.
What FAA rules actually require
FAA regulations require drones over 250g to be registered (recreational fliers pay $5 for a 3-year registration covering all their drones; Part 107 commercial operators register each aircraft separately). Recreational fliers must pass the TRUST knowledge test and fly under community-based safety guidelines. Commercial operators need a Part 107 remote pilot certificate. None of these rules restrict flying over specific types of property.
The altitude gray zone
Manned aircraft must maintain at least 500 feet AGL over suburban areas and 1,000 feet over congested areas under 14 CFR § 91.119. Drones have no analogous minimum altitude rule. A drone hovering at 50 feet over someone's backyard is technically legal under FAA rules (assuming registration and VLOS compliance), but courts and state laws are increasingly treating very low-altitude residential overflights as potential trespass or invasion of privacy.
The Causby doctrine: where your airspace rights end
U.S. v. Causby (1946) established that landowners have property rights extending above their surface, not just to it. The Supreme Court said rights extend to the "immediate reaches" above the land. What constitutes "immediate reaches" for a drone at 100 feet has not been definitively ruled on by any federal court as of 2026. State courts are filling this gap unevenly, which is why the rules differ so dramatically by state.
