Dumpster diving in Texas is generally legal when done on public property and where no specific city ordinances prohibit it. Once trash is placed outside for collection, it’s usually considered abandoned. However, diving into dumpsters located on private property—such as behind stores, inside gated areas, or near “No Trespassing” signs—can lead to trespassing or theft charges. Laws may vary by city, so it's important to check local regulations and avoid restricted or clearly marked areas.
