Both of the houses seen in the film are within a block of each other in the suburb of Toluca Lake, which straddles the borders of Los Angeles and Burbank in the San Fernando Valley.
The film's final punchline-a large two-story early-1950s Colonial house shown briefly at the end with a "Sold" sign on it and a front pathway flanked by the McClures' sheepdog and the Iversons' poodle-is also in Toluca Lake, at 10463 Kling Street.
