Is it legal to fly a drone over someone's house?

Question

Accepted Answer

The legality of flying a drone over residential property is a complex intersection of federal aviation regulations, state privacy laws, and common law principles regarding property rights. Because drone technology has outpaced the development of specific legislation, understanding the current legal landscape requires a nuanced look at the division of authority between national aviation agencies and local jurisdictions.

The Federal Framework: Airspace Authority

In the United States, the Federal Aviation Administration (FAA) holds exclusive sovereignty over the navigable airspace of the country. This means that a drone operator is generally permitted to fly over residential areas provided they adhere to federal safety guidelines.

Under FAA Part 107 regulations (for commercial pilots) and the Exception for Recreational Flyers, drones must be operated within the pilot’s visual line of sight, typically below 400 feet, and away from restricted airspace. The FAA does not explicitly prohibit flying over private property, as the agency maintains that property owners do not own the air above their homes up to the point of "navigable airspace." However, federal regulations do not supersede all other legal considerations, particularly those concerning privacy and nuisance.

The Privacy Threshold: Expectation of Privacy

While the FAA governs the flight of the aircraft, state and local laws govern the conduct of the operator. The most significant legal hurdle for drone operators is the "reasonable expectation of privacy."

Most states have enacted laws that specifically address the use of unmanned aircraft systems (UAS) to capture images or recordings of individuals or property without consent. If a drone is equipped with a camera, flying it over a backyard or near windows can be interpreted as an invasion of privacy. Legal precedents—often drawing from the "peeping tom" statutes or tort law—suggest that if an operator uses a drone to peer into private spaces where a person has a reasonable expectation of privacy, the operator may be held civilly or even criminally liable.

Nuisance and Trespass: Common Law Principles

Beyond privacy, common law principles of trespass and nuisance remain highly relevant. Although the Supreme Court established in United States v. Causby (1946) that landowners own only as much of the airspace above their land as they can reasonably use in connection with the land, constant or low-altitude drone flights can be legally challenged under the following theories:

Trespass to Land: While courts have traditionally been hesitant to define drone overflight as a physical trespass unless it interferes with the actual use of the land, persistent low-altitude flying that disturbs the property owner’s quiet enjoyment can constitute a trespass.
   Private Nuisance: This occurs when a drone operator’s actions substantially and unreasonably interfere with a property owner’s use and enjoyment of their land. Examples include excessive noise, hovering for extended periods, or creating a sense of surveillance that prevents the homeowner from using their yard.

Local Ordinances and State Legislation

Because federal law does not cover every aspect of drone usage, many municipalities have attempted to pass ordinances restricting drone flights over private property. However, this is a contentious area. The FAA has issued guidance (and has intervened in court cases) to clarify that local governments cannot regulate the flight path of an aircraft, as that is preempted by federal law.

Despite this, local governments are permitted to regulate the takeoff and landing of drones and can impose restrictions on how drones are used in relation to public safety, harassment, or surveillance. Consequently, a homeowner may find that while the FAA might allow the flight, local police or ordinances might prohibit the act of hovering or recording.

Best Practices for Responsible Operation

To remain within the bounds of the law and maintain neighborly relations, drone operators should adhere to the following principles:

1.  Transparency and Consent: If you intend to fly near residential property for photography, it is best practice to notify the property owner beforehand. Obtaining explicit permission effectively nullifies potential privacy complaints.
2.  Avoid Hovering: The primary complaint from homeowners is not the momentary transit of a drone, but the deliberate hovering over private property. Keep the drone moving and avoid loitering over specific backyards or windows.
3.  Respect Quiet Hours: Excessive noise from drone propellers can be a source of significant annoyance. Avoid flying during early morning or late evening hours when noise is more disruptive.
4.  Check Local Statutes: Always consult your state and local municipal websites for specific drone bylaws, as these can change rapidly and often include "no-fly" zones or specific privacy protections that exceed federal standards.

In summary, while there is no blanket federal ban on flying a drone over a residential property, doing so carries significant legal risks. If the flight crosses the line into surveillance, harassment, or a substantial interference with property enjoyment, the operator is likely to face legal consequences at the state or local level. Operating with a high degree of discretion and respect for privacy is the only way to ensure compliance with the evolving legal standards of the modern age.
