Dumpster diving is generally legal in Oregon, but the specifics depend on where you dive and how you do it. The key distinction is between public and private property:
- Public Property: Once trash is discarded in a public place, such as a curb for collection, it is considered abandoned and generally legal to take. This is supported by the 1988 Supreme Court decision in California v. Greenwood, which held that there is no reasonable expectation of privacy for discarded trash in public areas.
- Private Property: Dumpster diving becomes illegal if it involves trespassing on private property. Most dumpsters behind stores, inside fenced areas, or marked with “No Trespassing” signs are considered private. Entering these areas without permission can result in trespassing or theft charges.
Statewide and Local Laws
- State Law: There is no statewide ban on dumpster diving in Oregon. The practice is generally allowed as long as you are not trespassing or violating other laws.
- Local Ordinances: Some cities and counties in Oregon may have their own rules restricting dumpster diving, especially regarding the removal of recyclables or scavenging in certain public areas. Always check local regulations before diving.
When Dumpster Diving Is Illegal
- Trespassing: If you enter private property, climb fences, or ignore “No Trespassing” signs to access a dumpster, you are breaking the law and can be cited or arrested.
- Tampering with Locks or Fences: Forcing open a locked dumpster or entering a fenced area is illegal and can lead to criminal charges.
- Ignoring Posted Signs: Dumpsters marked with “No Trespassing” or “No Scavenging” are off-limits, and violating these warnings can result in fines or arrest.
- Disorderly Conduct or Littering: Making a mess, creating disturbances, or leaving trash behind can also result in citations for disorderly conduct or littering.
Best Practices for Legal Dumpster Diving in Oregon
- Ask Permission: If a dumpster is on private property, always ask the owner or manager for permission before diving.
- Respect Signs and Fences: Never enter fenced areas or ignore posted warnings.
- Stay Clean and Polite: Leave the area cleaner than you found it, and comply promptly if asked to leave.
- Check Local Laws: Some municipalities have specific ordinances—research before you dive.
