Dumpster diving does exist in Idaho and is a common activity for those seeking discarded items of value. Legally, Idaho does not have any statewide laws that specifically prohibit dumpster diving. In fact, following the 1988 Supreme Court decision in California v. Greenwood, searching through trash is generally legal once it has been left in a public space and ownership is considered relinquished.
Key Legal Points
-
No Statewide Ban: Dumpster diving is legal in Idaho at the state level, and there are no statutes that make the act itself a crime.

Trespassing Laws Apply: The main legal risk comes from trespassing. Most dumpsters are on private property, such as behind businesses or within fenced areas. Entering private property to access a dumpster without permission is considered trespassing and can result in a misdemeanor charge under Idaho law.
-
Public vs. Private Property: If a dumpster is placed in a publicly accessible area, such as a sidewalk or alley, and you do not cross any barriers or signs, dumpster diving is generally legal. However, if you have to cross a fence, gate, or ignore “No Trespassing” signs, it becomes illegal.

Business and Local Rules: Some businesses may post signs prohibiting dumpster diving or lock their dumpsters. Tampering with locks or ignoring posted warnings is illegal and can lead to charges.
-
Disorderly Conduct: Creating a mess, littering, or causing disturbances while dumpster diving can lead to fines or arrest for disorderly conduct.
