Is Surveillance Legal in Texas? What You Need to Know

In Texas, there is no reasonable expectation of privacy in a public space. This means a licensed PI can legally observe, photograph, and video record any person on a public street, in a parking lot, at a restaurant, in a park, or any other location accessible to the general public, without their knowledge or consent.

This principle is well-established in Texas case law and is consistent with federal constitutional standards. Evidence gathered through lawful public surveillance is fully admissible in Texas courts.

Surveillance becomes legally problematic the moment it crosses onto private property without permission. A PI cannot enter a fenced yard, peer through windows into a private residence, or place recording devices on private property without consent or a court order.

Texas Penal Code §21.15 specifically prohibits "invasive visual recording", photographing or recording a person in a private space where they have a reasonable expectation of privacy, including bathrooms, bedrooms, and changing areas, without their consent.

Drone surveillance is subject to both FAA regulations and the Texas Privacy Act (Texas Government Code Chapter 423). Under Texas law, using a drone to capture images of a person or private property without consent is generally prohibited unless an exception applies (law enforcement with warrant, licensed real estate photography, etc.).

Watson PI uses drone technology only within the bounds of applicable law and FAA Part 107 certification requirements.

Texas follows a one-party consent rule for audio recording under Texas Penal Code §16.02. This means at least one party to a conversation must consent to it being recorded. A PI cannot record a private phone call between two other people without the consent of at least one participant.

However, if you are a party to the conversation, you may legally record it in Texas, and that recording may be used as evidence.
