A dispute developed between Shirley and Glenn Rynes, who own the land that Kiddieland occupies, and Ronald Rynes, Jr. and Cathy and Tom Norini, who own the amusement park itself. The landowners sued the park owners in 2004, claiming that the park had an improper insurance policy and that fireworks were prohibited in the lease. The case was thrown out in a Cook County court and later in an appeals court. The landowners declined to extend the lease on the land in early 2009. In late June 2010, it was announced that Kiddieland would be demolished, nine months after the park closed to the public. A Costco store will be built in its place.
