Dumpster diving—searching through trash for discarded items—has become increasingly popular for reasons ranging from sustainability to saving money. But is it legal in Oregon? Here’s what you need to know about the law.
The Short Answer
Dumpster diving is generally legal in Oregon, but with important restrictions. The legality depends on where the dumpster is located and whether you are trespassing on private property.
Key Legal Points
1. Public vs. Private Property
Public Property: If a dumpster or trash is placed on public property (like a curb for collection), it is typically legal to search through it. This is based on a 1988 Supreme Court ruling (California v. Greenwood) that found there is no expectation of privacy for trash left in public spaces.
Private Property: Most dumpsters behind businesses, in alleys, or within fenced areas are on private property. Entering these areas without permission is considered trespassing, which is illegal—even if the dumpster itself is unlocked or unmarked.
2. Trespassing Laws
No Trespassing Signs: If you see signs or locked gates, do not enter. Ignoring these can result in fines, citations, or arrest for trespassing.
Permission: Always ask the property owner or manager for permission before diving into dumpsters on private property. Many businesses may say no, but some will allow it if you ask politely.
3. Local Ordinances
City and County Rules: While Oregon has no statewide ban, some cities or counties may have specific ordinances restricting dumpster diving or removing recyclables. Always check your local laws before diving.
Penalties for Illegal Dumpster Diving
First Offense: Usually results in a warning or minor citation if caught trespassing.
Repeat Offenses: Can lead to larger fines or even jail time, especially if property is damaged or if you ignore posted signs.
Best Practices for Legal Dumpster Diving
Only dive in public areas or with explicit permission on private property.
Avoid dumpsters behind fences, gates, or marked with “No Trespassing” signs.
Leave the area clean and do not make a mess.
Be polite and leave immediately if asked by property owners or law enforcement.
