Flying a drone over private property in California is not automatically illegal, but it can become illegal fast. Federal rules let drones use the airspace in general, and California layers trespass, nuisance, and some of the country’s strongest privacy laws on top. Whether a specific flight is lawful depends on how low the drone goes, what it is doing up there, and how it affects the people on the ground.
When a Flight Over Someone’s Land Crosses the Line
Property owners in California do not own the sky without limit, but they do control the airspace close to the ground. Civil Code Section 659 defines land ownership to include the space above it, subject to limits set by law.1California Legislative Information. California Code Civil Code 659 – Land Federal law claims the navigable airspace higher up. What sits in between is where drone disputes live.
No California court has fixed a specific altitude that separates a lawful overflight from a trespass. The general framework courts reference asks whether the drone entered the “immediate reaches” of the airspace and substantially interfered with the owner’s use of the land. As a rough guide, flights above 500 feet are usually outside those immediate reaches, flights below 50 feet are almost certainly inside them, and something around 150 feet turns on the facts: how long the drone lingered, what it was doing, and what was going on below.
A drone is a physical object occupying space, which is why a low overflight can support a trespass claim in a way that noise or odor cannot. The California Supreme Court held in Wilson v. Interlake Steel Co. that intangible intrusions without physical damage are handled as nuisance rather than trespass.2Justia. Wilson v. Interlake Steel Co. A drone hovering 20 feet above your yard is on the trespass side of that line.
Privacy Laws That Make a Flight Illegal Regardless of Altitude
Even a drone that stays high enough to avoid a trespass claim can violate California privacy law. Privacy is treated as an inalienable right under Article I, Section 1 of the state constitution, and two statutes do the practical work.3Justia. California Constitution Article I Section 1 – Declaration of Rights
Civil Code Section 1708.8
Section 1708.8, often called the anti-paparazzi law, applies to anyone, not just professional photographers. A person is liable for “physical invasion of privacy” when they knowingly enter the airspace above someone’s land without permission to capture images, audio, or other recordings of that person engaged in a private activity, if the intrusion would offend a reasonable person.4California Legislative Information. California Code CIV 1708.8 – Physical and Constructive Invasion of Privacy
The statute also reaches “constructive invasion” that involves no physical trespass. A drone using a zoom lens from over the street to record private activity inside a fenced yard can trigger liability if the footage could not have been captured without trespassing had the operator not used the technology.4California Legislative Information. California Code CIV 1708.8 – Physical and Constructive Invasion of Privacy
Damages are severe. A plaintiff can recover up to three times their actual damages, plus punitive damages. If the recording was made for a commercial purpose, the defendant must disgorge any proceeds. A court can also impose a civil fine between $5,000 and $50,000.4California Legislative Information. California Code CIV 1708.8 – Physical and Constructive Invasion of Privacy
Penal Code Section 647(j)
Section 647(j) makes it a criminal misdemeanor to use any device, and it names “unmanned aircraft system” specifically, to view the interior of a bedroom, bathroom, changing room, or any other space where the occupant has a reasonable expectation of privacy, with intent to invade that privacy.5California Legislative Information. California Code PEN 647 – Disorderly Conduct
A first offense carries up to six months in county jail, a fine of up to $1,000, or both.6California Legislative Information. California Code PEN 19 A second or later violation raises the ceiling to one year in jail and a $2,000 fine, and penalties climb further when the person recorded is a minor.7California Legislative Information. California Code PEN 647 – Disorderly Conduct
Civil Claims a Property Owner Can Bring
If a drone flies over your property in a way you didn’t consent to, you have more than one angle of attack. These claims can be stacked in the same lawsuit.
Trespass. California trespass law extends to indirect intrusions, and a drone entering the immediate reaches of the airspace above the land is a physical object occupying that space. If the flight substantially interferes with the owner’s use of the property, it can be treated as trespass.
Nuisance. Civil Code Section 3479 defines nuisance broadly as anything that interferes with the comfortable enjoyment of life or property.8California Legislative Information. California Civil Code 3479 – Nuisance A single high pass will rarely qualify. A drone hovering over the same backyard every weekend, generating persistent noise or lingering to film, is a much stronger claim. Courts weigh frequency, duration, and actual impact.
Statutory privacy invasion. Section 1708.8 brings treble damages, disgorgement, and fines up to $50,000. Layering it onto trespass and nuisance is what makes drone privacy cases considerably more expensive than an ordinary property dispute.
Criminal Exposure Beyond Privacy
Interfering With Emergency Operations
Penal Code Section 402 makes it a misdemeanor to impede emergency personnel at the scene of an emergency, and the statute expressly covers a person who operates a drone at that scene regardless of where the operator is standing.9California Legislative Information. California Code PEN 402 – Crimes Against Public Health and Safety This matters most during wildfire season, when a single hobby drone can ground aerial firefighting. Penalties reach six months in jail and a $1,000 fine.6California Legislative Information. California Code PEN 19
Government Code Section 853 also shields local agencies and their employees from liability if they damage a drone that was interfering with emergency medical services, firefighting, or search and rescue.10California Legislative Information. California Code GOV 853 – Unmanned Aircraft If firefighters knock your drone out of the sky, you cannot bill them for it.
Stalking and Harassment
Using a drone to repeatedly follow, watch, or intimidate a specific person can trigger stalking charges under Penal Code Section 646.9, which requires willful and repeated harassment combined with a credible threat placing the target in reasonable fear for their safety. A conviction carries up to one year in county jail and a fine of up to $1,000, and can escalate to state prison under aggravating circumstances such as a prior restraining order.11California Legislative Information. California Code PEN 646.9 – Stalking Penal Code Section 653m separately criminalizes repeated harassing electronic communications.12California Legislative Information. California Code PEN 653m
What You Can Do About a Drone Over Your Property
A property owner has real remedies. You can sue for trespass, nuisance, and statutory privacy invasion in a single lawsuit. You can report criminal conduct, especially voyeurism, stalking, or emergency interference, to local law enforcement. You can seek a restraining order against a repeat operator.
What you cannot do is shoot it down. The FAA treats registered drones as aircraft, and federal law prohibits shooting at any aircraft.13Federal Aviation Administration. What To Know About Drones Willfully destroying an aircraft is a federal felony under 18 U.S.C. ยง 32 that carries up to 20 years in prison, on top of FAA civil penalties.14Office of the Law Revision Counsel. 18 U.S. Code 32 – Destruction of Aircraft or Aircraft Facilities A drone struck by gunfire can also crash onto people below, which is why the rule exists.
The Federal Baseline the Operator Also Has to Meet
California’s rules sit on top of a federal floor. The FAA controls aviation safety, and states cannot override that, but the FAA has acknowledged that state law still governs trespass, privacy, voyeurism, harassment, and reckless endangerment tied to drone use.15Federal Aviation Administration. Section 4. Airspace Access for UAS An operator who follows every FAA rule can still be sued under Section 1708.8 or charged under Section 647(j).
The federal baseline itself is straightforward. Drones over 0.55 pounds must be registered through the FAA’s DroneZone portal for $5, good for three years.16Federal Aviation Administration. How to Register Your Drone Recreational pilots must pass the free TRUST safety test and carry the completion certificate.17Federal Aviation Administration. The Recreational UAS Safety Test (TRUST) Commercial operators fly under Part 107, which caps altitude at 400 feet above ground level, requires visual line of sight, and limits flights to daytime or civil twilight with anti-collision lights absent a waiver.18Federal Aviation Administration. If I Operate My Drone Within 400 Ft. Radius or 400 Ft. Above a Structure Registered drones must also comply with Remote ID, which broadcasts identification and location in real time.19Federal Aviation Administration. Remote Identification of Drones Flights over designated national security sites, including military bases and nuclear plants, are prohibited from the ground up to 400 feet.20Federal Aviation Administration. Critical Infrastructure and Public Venues
Local governments in California also regulate drone use in parks, near schools, and in other public spaces, and those rules generally survive federal preemption because they target conduct rather than airspace itself. The short version for anyone flying, or anyone whose yard keeps getting flown over: federal registration and altitude compliance is only half the picture, and in California it is often the less consequential half.
