 The house used for exterior shots, which was normally seen at the  beginning of every episode as well as various points throughout the  shows run, is at 11222 Dilling St., Studio City, California. Since  the series ended, the owners of the home have erected an iron fence,  let heavy shrubbery grow to cover much of the front, and have  suffered numerous trespassers. They also refused to let producers  use the home for exterior shots in the subsequent films in the  1990s.
