"Going Places" creators Robert Griffard and Howard Adler would end up employed with "Step By Step" as co-executive producers and members of its writing staff until the show's fifth season; Adler and Griffard later wrote an additional episode of the show as freelancers in the seventh season. Patrick Duffy directed several episodes, starting with the second season. The house shown in establishing shots for scenes set at the Lambert-Foster home is located at 2011 Fletcher Avenue in South Pasadena, California, although the series was actually filmed at Warner Bros. Studios in Burbank, California.
