Dumpster diving—the act of searching through trash or dumpsters for discarded items—raises questions about legality and property rights. In Maryland, the law does not explicitly prohibit dumpster diving at the state level, but important restrictions and local ordinances can affect whether or not it is legal in a specific situation.
State Law
Maryland does not have a statewide ban on dumpster diving. The practice is generally legal due to a 1988 Supreme Court decision (California v. Greenwood), which ruled that once trash is left for collection in a public place, there is no reasonable expectation of privacy, and it is considered abandoned property. This means that, in most cases, taking items from dumpsters is not illegal at the state level.
Key Restrictions and Considerations
Trespassing Laws: Dumpster diving is only legal if you are not trespassing. Most dumpsters are located on private property, such as behind stores or within fenced enclosures. Entering these areas without permission can result in trespassing charges. If a dumpster is behind a fence, locked, or accompanied by a “No Trespassing” or “Private Property” sign, it is off-limits.
Local Ordinances: Some Maryland cities and counties have their own regulations regarding dumpster diving. These may include requirements for permits, bans on making a mess, or prohibitions against salvaging certain materials. Always check local municipal codes before diving.
Signage and Locks: If a dumpster is locked or clearly marked with warning signs, accessing it is illegal and can result in fines or arrest.
Disorderly Conduct and Littering: Even if dumpster diving itself is not illegal, creating a mess or causing a disturbance can lead to citations for disorderly conduct or littering.
Private Property: Dumpster diving on private property (including retail parking lots or business premises) requires the owner’s permission. Without it, you risk being cited for trespassing.
Health and Safety: While not a legal issue, be aware that taking food or goods from dumpsters can pose health risks. Businesses are not liable for injuries or illness resulting from items taken from their trash.
Local Example
In Frederick County, Maryland, local officials have confirmed that dumpster diving is legal as long as the dumpster is not locked and there are no posted “No Trespassing” signs. This reflects the general approach across the state, but regulations can vary from one locality to another.

Practical Advice
Always check for posted signs, locks, or fences before approaching a dumpster.
Avoid trespassing on private property.
Research local ordinances in your city or county.
Be respectful and leave the area clean.
When in doubt, ask for permission from property owners or managers.
Dumpster diving is generally legal in Maryland, provided you avoid trespassing, respect posted signs and locks, and comply with local ordinances. The safest approach is to seek out dumpsters in public areas without restrictions and to always act respectfully and responsibly.
