Dumpster diving is not illegal statewide in Arizona, but several important legal conditions apply. The act itself—searching through trash that has been set out for collection—is generally legal, as affirmed by the 1988 Supreme Court decision in California v. Greenwood.
This ruling established that once trash is placed in a public area for collection, it is considered abandoned and there is no reasonable expectation of privacy.
However, local regulations and property laws play a key role:
- Trespassing: If a dumpster is located on private property, behind fences, or marked with “No Trespassing” signs, entering the property to access the dumpster is illegal and can result in trespassing charges. Many businesses and apartment complexes keep dumpsters on private premises. Tampering with locks or barriers is also prohibited.
- Municipal Ordinances: Some Arizona cities have specific rules. For example, in Mesa, trash is not considered abandoned until collected by the city, so removing items before pickup could violate local ordinances. Other municipalities may have similar rules or prohibit scavenging from city waste containers.
- Disorderly Conduct and Littering: Even if dumpster diving itself is legal, creating a mess, leaving trash behind, or causing a disturbance can lead to fines or charges for littering or disorderly conduct.
- Penalties: Trespassing in Arizona is a misdemeanor and can carry fines or even jail time, especially if you ignore posted warnings or repeat the offense.
Dumpster diving is legal in Arizona as long as you do not trespass on private property, ignore posted signs, tamper with locks, or violate local waste ordinances. Always check city and county regulations, and respect property boundaries to avoid legal trouble.
