Dumpster diving—the act of searching through trash bins for discarded items—is generally legal in Delaware, but there are important restrictions and local nuances to be aware of.
Statewide Legality
At the state level, there is no law prohibiting dumpster diving in Delaware. As long as you are not trespassing on private property, making a mess, or violating local ordinances, the practice itself is legal.
This aligns with the broader U.S. legal landscape, where the Supreme Court case California v. Greenwood established that once trash is placed in a public area (like the curb), it is considered abandoned property and can be searched or taken by others.
Local Restrictions
While Delaware does not ban dumpster diving outright, several cities and counties have their own rules:
- Wilmington: Rummaging through garbage containers without the owner’s consent is prohibited. This means dumpster diving on private property is banned unless you have permission from the owner. Public area dumpsters are generally fair game.
- Newark: Tampering with any waste containers, including dumpsters, without authorization is not allowed. Permission from the dumpster owner is required.
- Dover: Disturbing, removing, or scattering waste placed out for collection without permission is restricted. This limits diving in garbage cans, bins, and dumpsters.
- New Castle County: Similar to other jurisdictions, rummaging through waste containers without consent is prohibited.
Private Property and Trespassing
Dumpster diving becomes illegal if you enter private property without permission, bypass fences, or ignore “No Trespassing” signs. In such cases, you could face trespassing charges or other penalties. If a dumpster is locked or fenced in, it is off-limits unless you have explicit consent from the owner.
Safety and Other Considerations
Even where legal, dumpster diving can sometimes be met with suspicion or lead to complaints. Authorities may intervene if you are accused of disorderly conduct, littering, or making a mess. Always be respectful, clean up after yourself, and leave promptly if asked.
