Much of the filming for "Malcolm in the Middle" was done on location in various parts of the thirty-mile zone around Los Angeles. A privately owned home, located at 12334 Cantura Street in Studio City, California, was rented for upwards of $3,000 a day to film as Malcolm's house. Rebuilt in 2011, the property is no longer recognizable due to its modern two-floor design. However, the house directly to the left of it is nearly identical to what it looked like during filming, still making it a frequent stop for fans of the show. School scenes were filmed at Colfax Charter Elementary School, in North Hollywood, and the Lucky Aide was represented by a Drug Emporium at 6020 Lankershim Boulevard in North Hollywood. In "Stock Car Races", when Hal and the boys are entering a race track, the billboard behind the entrance displays the place as Irwindale Speedway, a real race track in Southern California. The last episode in the first season ("Water Park") was filmed at a water park called Wild Rivers (now closed as of 2011) located in Irvine, California. Though palm trees and desert scenery are seen in shots of the local region and town throughout the show, indicating a location in the Western United States, it is never revealed which state the show is set in (except for Francis's whereabouts in early seasons, such as his military school in Alabama and his job in Alaska).
