No, dumpster diving isn’t a federal crime. Dumpster diving is legal in the United States, as established by a 1988 Supreme Court decision in California v. Greenwood. The decision says that the discarded items are not in the person’s reasonable expectation of privacy, meaning no laws are violated when they are picked up by someone else. Federal legality however does not provide universal permission. Depending on the laws and ordinances of your city and state, and the laws of your state, dumpster diving is legal or not. There is a potential for dumpster diving to infringe on local trespassing laws particularly if the dumpster is located on private property. The first thing anyone thinking about dumpster diving should know is where that line is.
Key Takeaways
- Dumpster diving is legal in the United States, unless it is against local regulation. A Supreme Court decision in 1988, California v. Greenwood, holds that upon discarding something, it becomes part of the public domain.
- On the federal level, no particular legislation prohibits dumpster diving. The basis of its legality is the Supreme Court case California v. Greenwood (1988), in which the Court decided that materials left on the curb for pickup are classified as public property.
- It’s a whole new ball game when it’s private property. Diving into a dumpster that is located on private property (behind a store or in a fenced area) may result in trespassing or theft charges, particularly if signs are posted or the dumpster is locked.
- Can you dumpster dive Sephora? In general, it’s not illegal to dumpster dive at Sephora. But most Sephora shops are private property, so you should ensure that there is no sign of trespassing restrictions on the premise.
- There are a number of cities and local governments that have laws prohibiting or restricting the practice. For instance, Wood River, Illinois, enacted an ordinance in 2025 that prohibits dumpster diving and fines are $100 to $750.
- Three universal legal hazards: trespassing, theft and local ordinance violations.
The Supreme Court’s decision that made dumpster diving legal
The whole of the national law concerning dumpster diving is based on one Supreme Court case from 1988.
There’s one strong U.S. Supreme Court ruling that is the reason dumpster diving is not universally and immediately illegal. This decision established the legal rights and responsibilities of trash, and its connection with the Fourth Amendment of the United States Constitution, which safeguards citizens from unreasonable searches and seizures.
In California v. Greenwood (1988), the Supreme Court held that there is no reasonable expectation of privacy in garbage which is placed outside the “curtilage” of the home for collection.
It is well-known,” the ruling said, “that plastic garbage bags on or near a public street are easily accessible to animals, children, scavengers, snoops and other people.”
This decision was in a case of a police search, but directly impacted dumpster diving. Why shouldn’t private citizens be allowed to do what even the cops are allowed to do: search through trash that they’ve discarded without a warrant? This decision set the national precedent. However, it is possible for it to be superseded in certain jurisdictions by local laws.
There are three legal issues that concern dumpster diving in all states
1. Trespassing
The private sector makes a huge difference. Diving into a dumpster may result in trespassing or theft charges if it is located behind a business or in a fenced yard or area.
Police may question, ticket, or even arrest you if a dumpster is next to a building or in a fenced area that has the “No Trespassing” sign.
Darryl Brown, O.M. Vicars Professor of Law at the University of Virginia, says, “Someone could be committing a minor trespass if they got into a privately owned dumpster, particularly if the dumpster is on private property.
2. Theft
The items that are thrown away are normally abandoned property, but there are instances when throwing away items can turn into stealing.
Items left in dumpsters or garbage cans are generally considered abandoned property, and a dumpster diver is not likely to be charged with theft if he or she removes items from a dumpster. In some jurisdictions, however, if a municipality has claimed ownership of waste via its waste management system, removing waste from that waste stream can be considered theft of municipal property.
3. Local Ordinance Violations
Although the Supreme Court, in a ruling that is over 40 years old, indirectly allows dumpster diving on public land, it may result in fines and criminal charges as many cities and local governments have ordinances against or restrict dumpster diving.
“Practically speaking, dumpster diving is almost always illegal,” said Jeff Ferrell, professor emeritus at Texas Christian University and author of two books on scavenging, who said many places have contended that once trash is in a dumpster, it’s a part of the city’s waste management system.
Is It Illegal to Dumpster Dive at Sephora?
This is one of the most frequently asked dumpster diving questions, and it has a complicated answer.
In general, it is not against the law to dumpster dive at Sephora. Most of the Sephora stores are regarded as private property so you need to be sure that there are no signage visible on the premise that restrict trespassing. If you don’t see such a sign, it’s green light. However, if you can see a No Trespassing sign on Sephora and you go there and still rummage through their dumpster, you could be cited for trespassing. This can result in a life-time ban or even charges for disorderly conduct, illegal dumping or littering.
In March 2025, the Sephora’s Beauty Insider Community confirmed that dumpster diving is not permitted at Sephora stores. It is not allowed under the corporate policy even if the store manager or employee allows it.
In the real world, Sephora dumpster diving is like this. The majority of Sephora stores are on private commercial property, dumpsters are located at the back of the store. The one place is enough to put the dumpster firmly in private property territory. If you break into it without permission you could be charged with trespassing, no matter what is in the dumpster.
The Sephora stores typically comply with city and state regulations for dumpster divers. When Sephora’s dumpsters are on their own property, you have to be cautious of things such as gates and fences. There are also signs that prohibit trespassers on Sephora’s dumpster diving laws as they can lead to trouble if overlooked. Even if no signs, fences, or gates are present, it will always be a good idea to ask for their higher official’s permission because in that way you will never get in trouble.
State-by-State Overview: Illinois, North Carolina, Pennsylvania, Florida, Oklahoma, Texas, and Iowa
Illinois
An ordinance was passed in 2025 in Wood River, Illinois that prohibits dumpster diving and fines up to $750. There is no statewide legislation in Illinois that prohibits dumpster diving, but cities and towns have been increasingly active in regulating dumpster diving by enacting local ordinance. The state’s general permissiveness is superseded by the rules of the major cities in Illinois, including Chicago. Before diving, Illinois locals should verify local ordinances.
North Carolina
There is no state law that bans dumpster diving in North Carolina. The practice is generally allowed on public property under California v. Greenwood. The trespassing laws of North Carolina are quite strict when it comes to dumpsters on private property, however, and many commercial properties have No Trespassing signs that make it clear that any trespassing is considered a legal violation. Charlotte, Raleigh and other municipalities have other local ordinances that impose further restrictions.
Pennsylvania
There is no state law in Pennsylvania that specifically prohibits dumpster diving. The California v. Greenwood standard is followed, and dumpster diving on public property is generally legal. Dumpsters on private property are subject to the criminal trespassing law in Pennsylvania (Title 18, Section 3503). There are city-specific municipal waste rules in Philadelphia and Pittsburgh that could impact dumpster diving in those cities.
Florida
Florida’s climate and tourism industry make it one of the states where dumpster diving is an issue. There is no statewide trespass law prohibiting dumpster diving on public property in Florida, but trespass law does apply to private property dumpsters. Under Florida Statutes Section 810.08, criminal trespass is a second degree misdemeanor in Florida when trespasser is warned to leave. Florida’s high concentration of retail property with back access dumpster areas should be especially mindful of commercial property boundaries for divers.
Oklahoma
There is no statewide law in Oklahoma that prohibits dumpster diving. Under federal precedent, the practice is allowed on public property. Private property dumpsters are subject to trespass laws in Oklahoma and municipalities such as Oklahoma City and Tulsa have their own waste management laws. The ordinance issues are less complicated in rural areas of Oklahoma than in urban areas.
Texas
Most large dumpsters are located on private property and, in Texas, it is illegal to sift through them, particularly the ones filled by well-known retailers. There is no statewide prohibition on dumpster diving in Texas, but Texas Penal Code Section 30.05 does apply to dumpsters that are used for commercial dumpsters on private property. Each city in Texas has a set of codes for municipal waste that divers should check before heading out.
Iowa
There is no state law banning dumpster diving in Iowa. Generally, the practice is allowed on public property pursuant to the California v. Greenwood framework. Private property dumpsters are covered by Iowa’s criminal trespass law. Divers should check local rules before diving in any particular location in Iowa, as some local ordinances may put more restrictions on diving.
What is and is not allowed legally
It’s crucial that every individual who is thinking about dumpster diving realize where the legality lies.
Generally speaking, it is legal to:
- Access to dumpsters on public property without signage barring access
- Picking up items that were thrown out at the curb for pickup
- Dumping on private land with explicit permission of the owner
- Recycling abandoned items that are clearly abandoned
The following is generally unethical:
- Entering behind fences, gates or marked private property to access dumpsters
- Staying on a property after being told to leave by the property owners or management.
- Diving in areas with No Trespassing signs on them.
- Unlocking or unsecuring dumpsters
- Failure to comply with certain city ordinances prohibiting or limiting the practice
- Dumping garbage in a manner that constitutes a littering/sanitation offence
When in doubt, please consult local ordinances. When dumpster diving, remember safety first and consider the ethics.
Safety and Health Risks of Dumpster Diving
The legal issues are not the only ones that concern the dumpster divers, especially those who want to find beauty products and food items.
The improper storage of cosmetics could cause premature expiration and growth of bacteria. If the mascara is lying in a hot dumpster for a couple of days, then there may be infection-causing bacteria in the tube.
These common products may be either scrapped testers or returned products from other customers. In its response to dumpster diving for beauty products, Ulta Beauty said: “Health and safety is a top priority for Ulta Beauty and we strongly discourage the unsafe, and sometimes illegal practice of dumpster diving.”
Other dumpster diving dangers include:
- Commercial dumpsters containing sharp objects such as broken glass, metal edges, and industrial waste.
- Exposure to chemicals due to cleaning products, industrial waste or other improperly disposed of chemicals
- Biological contaminants of food waste, medical disposal or contaminated materials
- The risk of physical injury due to climbing into or climbing into and reaching into large commercial dumpsters.
- Risk of legal liability for trespassing on private land.Risk of legal liability for trespassing on private land.

Expert and Legal Perspectives
Practically, dumpster diving is almost always illegal, according to Jeff Ferrell, professor emeritus at Texas Christian University and author of two books on scavenging: Many places have said that once trash is in a dumpster, it’s the city’s waste management system.
Darryl Brown, O.M. Vicars Professor of Law at the University of Virginia, says that the dumpster divers could not be charged with theft for anything they remove from the dumpster because once it’s thrown in a dumpster or other trash bin it’s abandoned property. But it may be a slight trespass violation to access a private dumpster, particularly on private property.
FindLaw confirms that the Supreme Court decision in California v. Greenwood held that people have no expectation of privacy in the trash they have left outside in a public area, but that dumpster diving can violate local trespassing laws especially if the dumpster is on private property.
Conclusion
There is no federal law in the United States that bans dumpster diving. The Supreme Court’s 1988 decision in California v. Greenwood set the legal baseline for the country, ruling that there is no expectation of privacy in trash left in a dumpster on public property, and thus allowing dumpster diving on public property in all 50 states.
The takeaway from this is that being legally permitted by the federal government is not the same as being practical. Most commercial dumpsters in most American cities are legally prohibited from being used by the public, because of the three legal hazards that apply to all dumpsters: trespassing on private property, theft of municipal waste, and violation of local ordinances. The majority of dumpster diving situations people actually come across involve trespassing, as most retail dumpsters are found on private property, such as Sephora and other commercial businesses.
The safest way to dumpster dive is to consult with your local municipal ordinance first, inspect for No Trespassing signs and fencing that marks private property, and ask for specific permission from property owners or management to access any commercial dumpster. If in any doubt, presume that the dumpster is private property and that there is a risk of legal liability if it is used without permission.
Frequently Asked Questions
1. Is it against the law to dumpster dive?
Not federally. In 1988, the Supreme Court ruled that dumpster diving on public property is generally legal in California v. Greenwood. But it may be prohibited in certain places due to local ordinances, trespassing and private property laws.
2. Can you dumpster dive Sephora?
This is dependent on the particular place. The majority of Sephora dumpsters are located on private commercial property. Unauthorized use of them can lead to trespassing charges. The company’s policy prohibits dumpster diving at its stores, which was confirmed in March 2025 in the company’s community forum.
3. Can dumpster diving be done in Illinois, North Carolina, Pennsylvania, Florida, Oklahoma, Texas and Iowa?
The California v. Greenwood precedent is accepted in all seven states for dumpster diving on public land. Trespassing laws are in effect in all seven states for dumpsters on private property. Wood River has specific bans in place with fines of $100 to $750, among other municipalities in Illinois. It is important to check local ordinances in all seven states before proceeding.
4. May I be arrested for dumpster diving?
Yes, in certain circumstances. Access to a dumpster by trespassing on private property may lead to arrest. If someone is asked to leave a dumpster and they continue to use it, they can be charged with criminal trespass.
