What Is Criminal Trespass in Illinois?

Criminal trespass in Illinois occurs when someone knowingly enters or remains on property without permission, including land, buildings, or vehicles. It’s typically a Class B misdemeanor for first offenses, punishable by up to 6 months in jail and fines up to $1,500. Aggravated trespass, such as entering a school, residence, or using force, escalates to a Class A misdemeanor or felony with up to 1 year in jail or 1-3 years in prison. In Will County areas like Joliet and Plainfield, charges often stem from disputes, misunderstandings, or unauthorized entry to private property. Key elements include “knowingly” acting without authority—proving lack of intent can be a strong defense.
