Is It Illegal to Dumpster Dive in Wyoming ? Here’s What the Law Says

Dumpster diving is generally legal in Wyoming at the state level, but where and how you do it can easily turn a legal hobby into trespassing or even theft.

State Law: Is Dumpster Diving Itself Illegal?

Wyoming does not have any statewide statute that directly bans dumpster diving. That means going through trash is not automatically a crime just because you’re looking in a dumpster. However, your legality hinges on where the dumpster is located and what local rules say.

Courts and law-enforcement generally treat trash in publicly accessible areas as abandoned property, especially when it’s sitting at the curb or in an open, shared dumpster area.

Still, if a dumpster sits on clearly private property—like behind a locked gate, up against a building, or in a posted “No Trespassing” area—stepping onto that property to access it can be a crime even if the state doesn’t outlaw dumpster diving itself.

The Big Catch: Trespassing and Theft

The main legal risk in Wyoming is trespassing, not the act of sorting through garbage.

• Going onto private property (hopping fences, ignoring “No Trespassing” or “Employees Only” signs) to reach a dumpster can lead to criminal trespass charges.
• Under Wyoming law, trespassing can carry penalties of up to about a $750 fine and up to six months in jail for more serious or repeated violations.​
• If a business or property owner argues that items in the dumpster weren’t legally abandoned yet, you could also face theft accusations for taking those items without permission.

In practice, many police officers will start with a warning if you’re in a gray area and not causing trouble, but the law allows for citations or arrest if you refuse to leave or return repeatedly.

Public vs. Private Dumpsters

Where the dumpster is has a huge impact on whether your diving is likely to be treated as legal.

More Likely to Be Legal (If No Other Rules Are Broken)

• Dumpsters in open parking lots that anyone can walk through.
• Containers placed at the curb for city pickup, where there are no posted signs limiting access.
• Public trash cans in parks or public spaces, as long as no local ordinance bans scavenging.​

In these situations, there’s no fence to hop or sign to ignore, so trespass is less likely to be an issue, though a business or city can still ask you to leave.

Higher-Risk Locations

• Dumpsters behind locked gates, alleys with “Private Property” or “No Trespassing” signs, or fenced loading docks.
• Dumpsters inside apartment complexes, behind controlled-access gates or in clearly private resident-only areas.
• Containers near recycling, hazardous waste, or secure commercial waste zones, which may have special rules.​

Entering these spaces without permission is where trespass, property damage, or theft charges become likely.

Local Ordinances: City Rules Can Be Stricter

While Wyoming law is relatively permissive, cities and counties can adopt their own rules that effectively restrict dumpster diving.

Some local codes can:

• Prohibit “scavenging” in city trash or recycling containers.
• Treat rummaging through public dumpsters as a form of littering, nuisance, or disorderly conduct if it creates a mess or blocks access.
• Allow tickets or fines if you’re caught taking items from recycling or special waste streams.​

Guides and hobby sites point out that many Wyoming towns still don’t have specific anti-dumpster-diving ordinances, especially in smaller, rural communities, as long as divers stay off private property and clean up after themselves.

Examples Around Wyoming

Several sources list common Wyoming cities as generally “legal” for dumpster diving, with the usual trespass caveats:

• Cheyenne, Casper, Laramie – Often mentioned as strong spots for “legal if not trespassing” dumpster diving due to larger retail areas and more accessible parking-lot dumpsters.
• Smaller towns like Evanston, Riverton, Cody, Wheatland, Kemmerer, Thermopolis, and Mills are noted as not having explicit anti-diving ordinances but expecting divers to stay off clearly private property and avoid making a mess.​

Even in places people call “legal,” businesses might post signs, lock their dumpsters, or call law enforcement if they view divers as a nuisance or safety risk.

Day vs. Night Dumpster Diving

Wyoming does not have a separate law that makes nighttime dumpster diving illegal. Legally, the rules are the same day or night: trespass and local ordinances still apply.

However:

• Diving late at night may draw more attention from police or security because it looks more suspicious.
• Some divers prefer early morning or late-night hours for privacy and quieter stores, but that comes with a higher chance of someone calling the police on “suspicious activity.”​

Possible Penalties If Things Go Wrong

If your dumpster diving crosses a legal line, you could face:

• Trespass: fines up to around $750 and up to six months in jail in more serious or repeat cases.​
• Theft: if a property owner claims items in the dumpster still belong to them or weren’t abandoned.
• Local ordinance violations: tickets or fines for violating a city’s anti-scavenging rules, littering, or nuisance codes.

You can also be banned from specific locations (stores, complexes, business parks) and charged again if you return after being told to stay away.

How to Dumpster Dive Legally and Safely in Wyoming

If you decide to dumpster dive in Wyoming, these practices significantly lower your risk:

1. Stay off clearly private property
   • Don’t hop fences, squeeze through locked gates, or ignore “No Trespassing” and “Employees Only” signs.
2. Stick to open, accessible areas
   • Choose dumpsters in open parking lots or areas that are clearly accessible to the general public, with no barriers or warning signs.
3. Respect posted rules and locked dumpsters
   • If a dumpster is locked or there’s a sign saying “No Dumpster Diving,” respect it; forcing locks or ignoring signs can quickly turn into trespass or property-damage charges.
4. Ask for permission when possible
   • Some businesses are happy to let you take discarded items—as long as you ask first and follow their rules.​
5. Don’t make a mess
   • Leaving trash scattered around can lead to littering or nuisance citations and make businesses more likely to crack down. Always leave the area cleaner than you found it.
6. Be mindful of safety
   • Broken glass, spoiled food, chemicals, and medical waste can all pose health risks, regardless of legality.​
7. Check local rules beforehand
   • Look up your city or county’s municipal code—many are searchable online—to see if “scavenging,” “dumpster,” or “refuse” are mentioned specifically.

Bottom Line: Is Dumpster Diving Illegal in Wyoming?

• At the state level: Dumpster diving is generally legal in Wyoming because there is no law that outright bans going through trash, especially when it’s discarded in public areas.
• In practice: It becomes illegal when it involves trespassing, ignoring posted signs, breaking into closed areas, or violating local ordinances on scavenging or littering.

If you stick to publicly accessible dumpsters, avoid private property, respect local rules, and clean up after yourself, you can usually dumpster dive in Wyoming without breaking the law.
