Dumpster diving in Oregon is generally legal, but there are important restrictions and local nuances you need to know.
What the Law Says
- State Law: Dumpster diving is legal in Oregon, supported by the 1988 Supreme Court case California v. Greenwood, which ruled that there is no reasonable expectation of privacy for trash left in public spaces.
- Public vs. Private Property: The key distinction is location:
- Public Property: If the dumpster or trash is on public property (such as a curb or open alley), it is legal to search through it.
- Private Property: If the dumpster is on private property (e.g., behind a store, inside a fenced area, or marked with “No Trespassing” signs), entering to access it can be considered trespassing, which is illegal without explicit permission.
- Local Ordinances: Some cities and counties in Oregon may have their own rules that further restrict or prohibit dumpster diving, especially regarding the removal of recyclables or scavenging from certain types of bins.
Key Points to Remember
- Never enter fenced, locked, or clearly marked “No Trespassing” areas to access dumpsters; this is trespassing and can lead to fines or arrest.
- Always check for local city or county ordinances before diving, as some municipalities have specific bans or requirements.
- If asked to leave by a property owner or law enforcement, comply immediately to avoid escalation or legal trouble.
- Dumpster diving is generally safer and more accepted in public spaces and in cities like Portland, which actively support waste reduction efforts.
- Best practice: Ask store owners or managers for permission if you wish to dive in dumpsters located on private business property.
