When it comes to dumpster diving—searching through trash or dumpsters for salvageable items—many Mainers wonder if it crosses a legal line. The answer is nuanced: dumpster diving is generally legal in Maine, but there are important restrictions and considerations to keep in mind.
No Statewide Ban—But Local Rules Apply
Maine has no state law that explicitly forbids dumpster diving. In fact, according to legal and local news sources, dumpster diving is technically legal across all 50 states following the landmark 1988 Supreme Court decision California v. Greenwood. This case determined that trash set out for pickup is considered abandoned and part of the public domain, making it legal to be searched unless conflicting local ordinances exist.
However, just because there’s no blanket ban doesn’t mean you’re free to help yourself to any dumpster:
Municipalities, counties, or individual townships in Maine can set their own rules. Some cities and towns may have ordinances restricting or banning dumpster diving, particularly in residential neighborhoods or business districts.
Private property laws still apply. If a dumpster is on private property, behind a fence, locked, or marked with “No Trespassing” signs, entering, climbing, cutting locks, or jumping fences can all be considered trespassing or even breaking and entering, which are criminal offenses.
Store policies matter: Many stores lock up or fence off dumpsters due to safety, liability, or privacy concerns, and ignoring such barriers can land you in legal trouble.
The Legal Fine Print
Public vs. Private Trash: If items are placed on the curb or in a public dumpster (with no trespassing restrictions), it’s usually legal to salvage items. Once on public property, discarded items are generally fair game.
Trespassing & Theft: Taking anything from a dumpster that’s on private land, or ignoring posted warnings, can lead to criminal trespass or theft charges. Always respect signage, fences, and locks.
City/Local Ordinances: Some locations may have ordinances directly banning or restricting scavenging. Always check town or city codes before attempting to dumpster dive.
Health and Safety Hazards
Even where dumpster diving is legal, safety is a serious concern. Dumpsters can expose divers to sharp objects, bacteria, spoiled food, and hazardous chemicals. Some may be treated with pesticides, or contaminated with fecal matter, leading to higher risk of cuts and infections, especially in warmer months. The risk extends beyond the law to your personal health—so be vigilant and suitably cautious.
Tips for Dumpster Diving Legally in Maine
Check Local Laws: Always look up city or county codes; some prohibit dumpster diving or scavenging in certain areas.
Obey Signs and Barriers: Don’t enter areas marked private, fenced, locked, or posted with “No Trespassing.”
Avoid Making a Mess: Leave the area as you found it. Creating a mess can lead to complaints or fines.
Respect Property Owner Requests: If asked to leave, do so immediately to avoid potential legal issues.
Practice Safety: Wear gloves, examine items carefully, and avoid picking food unless it’s safe and sealed.
Dumpster diving is legal in Maine as long as you do not trespass on private property, ignore posted warnings, or violate local ordinances. Responsible divers who stick to public dumpsters and respect signs and property lines should not encounter legal issues. For absolute certainty, check with your local town or city before you go—and always prioritize your safety and respect for others’ property.
