Drones for Private Investigators: What’s Legal

A drone looks like the perfect surveillance tool for a private investigator: quiet, high, and able to see over fences. In some states it is also the fastest way to turn a good case into a misdemeanor charge, a civil lawsuit and evidence the court throws out.

This guide covers what PIs can legally do with a drone in 2026, the state laws that catch investigators out, and how to use one without wrecking your case or your license.

Step one: you need a Part 107 certificate

The FAA does not care that you are a licensed investigator. If you fly as part of paid work, you are a commercial operator under Part 107. That means passing the FAA knowledge test (about $175, 60 questions, 70% to pass), registering the drone, and making sure it broadcasts Remote ID. Our drone security jobs guide walks through the certificate step by step.

Part 107 also sets the flight rules: generally under 400 feet, within visual line of sight, limits on flying over people, and no flights in controlled airspace without authorization. A violation is an FAA problem on top of any state privacy problem.

The state laws that catch PIs

Federal law controls the airspace. States control privacy and surveillance. These are the laws every investigator should know:

Texas: the strictest drone surveillance law

• Gov’t Code § 423.003: using a drone to capture an image of an individual or privately owned property with intent to conduct surveillance is a Class C misdemeanor. It is a defense if you destroy the image as soon as you learn it was captured illegally.
• § 423.004: possessing, disclosing, displaying or distributing such an image is a Class B misdemeanor.
• § 423.005: an image captured in violation of the law generally cannot be used as evidence in court.
• § 423.006: the property owner or person filmed can sue for a civil penalty of $5,000 for all images captured in one episode, or $10,000 if the images were disclosed, plus attorney fees.

In 2023 the Fifth Circuit upheld these surveillance provisions in National Press Photographers Ass’n v. McCraw. For a PI, a Texas drone video of a claimant in their backyard can cost more than the case is worth.

Florida: no drone surveillance of private property

Florida Statute § 934.50(3)(b) bars using a drone to record privately owned property, or its owner, tenant or occupant, with the intent to conduct surveillance that violates a reasonable expectation of privacy, without written consent. A person is presumed to have that expectation when they cannot be seen by people at ground level in a place where those people have a legal right to be. The person filmed can sue for damages, punitive damages, attorney fees and an injunction.

California: constructive invasion of privacy

California Civil Code § 1708.8 makes it a civil wrong to capture images or recordings of someone in a personal or family activity, in a way that is offensive to a reasonable person, using any device, when the image could not have been captured without trespassing unless the device was used. No physical trespass is needed.

Other states

Many states have their own drone, voyeurism, trespass or harassment laws, and they change often. Check your state’s statute and your licensing board’s rules before you fly on a case. Our PI licensing index links to each state’s regulator.

What a PI can usually do with a drone

• Scene and location documentation: overview shots of an accident scene, a commercial property, a public road or a worksite, with permission where needed.
• Insurance and property cases: documenting roof damage, land boundaries or property condition with the owner’s written consent.
• Planning: checking access roads and public vantage points before a ground surveillance job, without filming people.
• Client-owned property: filming a client’s own site for theft, trespass or damage, with the client’s written consent.

What gets PIs in trouble

• Flying over a subject’s home or yard to see what you cannot see from the street.
• Filming into windows or fenced areas. This can cross into voyeurism or invasion of privacy, whatever the drone-specific laws say.
• Recording audio. Drone footage with sound can raise eavesdropping issues, especially in all-party consent states. Turn audio off.
• Following a subject with a drone, which can look like stalking or harassment.
• Taking off or landing on private property without permission. That is trespass, whatever the airspace rules say.
• Flying without Part 107 and then trying to use the footage. Opposing counsel will ask.

A drone-use checklist for investigators

1. Confirm you hold a current Part 107 certificate and the drone is registered and broadcasting Remote ID.
2. Check the airspace for the location and time, including controlled airspace and temporary flight restrictions.
3. Check your state’s drone surveillance and privacy laws, and your licensing board’s rules.
4. Get written consent from the property owner for any flight over, or footage of, private property.
5. Plan the flight so the camera only captures what is visible from a public place.
6. Turn off audio recording.
7. Log the date, time, location, pilot, purpose and consent for every flight.
8. Keep original files unedited, and document the chain of custody.
9. If you capture something your state’s law forbids you to keep, delete it promptly and note that you did.

Footage is only useful if your notes hold up too. Our incident report template works as a model for documenting each flight.

The gear

For documentation work, a small, quiet drone with a good camera is enough. The DJI Mini 4 Pro is light and quick to deploy, and the DJI Air 3S adds a telephoto camera. Read best drones for security first for the DJI sales situation in the US.

Frequently asked questions

Can private investigators use drones?

Yes, within federal and state law. A PI flying for a paying case needs an FAA Part 107 certificate, and several states, including Texas and Florida, restrict drone surveillance of people and private property.

Is it legal to use a drone for surveillance?

It depends on the state and what you film. Filming what is visible from public places is generally lower risk. Using a drone to watch a person or their private property can be a crime in Texas and lead to civil liability in Florida and California.

Can drone footage be used as evidence?

Often, if it was captured legally and you can show where it came from. In Texas, images captured in violation of the state drone law generally cannot be used in court, so illegal footage can sink a case.

Do I need a Part 107 license to fly a drone for a PI case?

Yes. Any flight for business or pay is commercial under FAA rules, regardless of your PI license. You must pass the Part 107 knowledge test and register the drone.

Can a PI fly a drone over someone’s house?

In most cases you should not. Flying over or filming into a home or fenced yard risks privacy, trespass and voyeurism claims, and in Texas and Florida it can violate drone surveillance laws.
