The Illinois 5-day notice to quit for illegal activity is an eviction notice used to inform a tenant that they have committed an illegal activity on their rented property and must vacate the premises within five (5) days. Failure to move out within the five-day notice period means that the landlord can commence an eviction action against the tenant. In accordance with state law, any act that would constitute a felony or a Class A misdemeanor is considered an illegal act. By delivering this notice to quit, the landlord considers the lease agreement between the parties to be terminated and that they may recover possession of the property.
