The legal answer to "can you fly over private property" is yes, with significant caveats depending on your state and what you do with the camera. The practical answer is that respectful, minimal-impact flying is both the ethical standard and the safest way to avoid legal exposure.
Altitude and camera discipline
Fly high enough to eliminate any reasonable claim of surveillance. At 200 feet over a neighborhood, you are clearly transiting, not surveilling. At 50 feet hovering over a backyard, the situation is inverted regardless of whether you are actually recording. Keep the camera pointed away from residential windows and yards unless you have explicit permission or a clear editorial purpose.
Notifying neighbors
For planned shoots near residential areas, a brief conversation with neighbors before you fly eliminates most conflicts before they start. Explain what you're filming and roughly how long the flight will take. Most people are fine with a quick flight once they know there's a real person and a real purpose behind it, not a surveillance operation.
How long is too long to hover
Duration matters legally. A single transit pass over a property at 200 feet raises little concern. Hovering over the same backyard for 5-10 minutes is a different situation: courts and law enforcement treat sustained low-altitude hovering as evidence of surveillance intent, even if no footage was captured. Keep flights purposeful and move on once you have what you need.
Flying your own neighborhood
Flying over your own house or neighborhood is not automatically legal, even if you own the property directly below. If you take off and land from your own property, you still fly through airspace above other properties during the flight. HOA rules may prohibit launches from shared community land. Local ordinances may restrict residential flights. Check local rules before assuming that owning a house gives you the right to fly commercially over your neighbor's property.
Tip: Commercial operators using drone footage of private property for real estate, construction, or marketing should obtain written permission from the property owner before the flight. Even if the flight is technically legal, the footage may not be usable commercially without consent, particularly in states with drone privacy statutes.
