Each episode depicts typical situations for a new blended family. Family members’ differences cause arguments and resentments, but over time they grow to tolerate and become loyal to one another.

On September 29, 2017, Hulu acquired the streaming rights to Step by Step along with fellow Warner Bros. TV properties Family Matters, Full House, Hangin' with Mr. Cooper and Perfect Strangers, in addition to fellow ABC programs Boy Meets World, Dinosaurs and Home Improvement.

Staci Keanan and Christopher Castile had previously appeared on the Miller-Boyett-produced ABC sitcom Going Places, which debuted the season prior to Step By Step, playing characters with no familial relation (Keanan – who played Lindsay Bowen, the teenage neighbor of the show's adult characters – as a series regular, Castile as a recurring character). Keanan was the first of the two Going Places stars to be cast on Step By Step in the spring of 1991. Castile, who had played gawky child Sam Roberts on Going Places, brought the same character traits to the Mark Foster role, which was speculated to be Miller-Boyett's continued attempt to give the Family Matters character Steve Urkel a white counterpart. In a similar instance of hiring actors over from their other TV series, the producers also cast Josh Byrne as Brendan Lambert on Step By Step, after he had just finished a supporting role as Patrick Kozak on Miller-Boyett's single-season CBS sitcom The Family Man.

The amusement park seen in the opening credits is depicted as being located along the shores of Lake Michigan in Wisconsin (no amusement park like this actually exists in Port Washington, but it is similar to Bay Beach Amusement Park in Green Bay, Wisconsin). The one used is actually Six Flags Magic Mountain in Valencia, California, located miles inland from the Pacific Ocean. The body of water depicted in the opening and closing credit sequences (the latter being seen on in season one) located next to the roller coaster – which is digitally inserted into that particular excerpt – is placed over what in actuality is the parking lot of Six Flags Magic Mountain.

The series returned to U.S. syndication on October 7, 2013, when the Hub Network began airing reruns; the network dropped it on October 12, 2014, as part of a change in the focus.

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.

ABC Family was the first to acquire cable television rights to the series, and it became one of the cable channel's longest-running off-network syndicated programs in its history. Reruns began airing on there in 2001 (on what was then known as Fox Family), airing in various timeslots during its run ranging from late afternoon to the morning hours. On March 26, 2010, ABC Family's contract expired after less than nine years.

Warner Home Video released a six-episode Television Favorites collection on DVD on June 27, 2006. Warner Archive Collection has released the entire series on DVD in Region 1. These are Manufacture-on-Demand (MOD) releases, available from Warner's online store and Amazon.com.

ABC chose to delay the series' sixth season to the 1996–97 mid-season (premiering in March 1997), in order to make room on that season's fall schedule for freshman sitcoms Sabrina the Teenage Witch and Clueless, which joined established series Family Matters and Boy Meets World on the TGIF lineup; the network canceled it after six seasons in May 1997, due to declining ratings. CBS concurrently reached a deal with Miller-Boyett Productions to acquire the rights to it and Family Matters from ABC, as that network attempted to build its own Friday night lineup of family-friendly situation comedies for the fall of 1997, called the "CBS Block Party". The series' ratings, which had been declining for several seasons, continued to erode, and the show ended its run in June 1998. It ended without an official series finale, although the last episode centered on Frank and Carol considering selling the house. According to Staci Keanan and Christine Lakin, the series was supposed to end with Dana and Rich's wedding at the house, and elaborate preparations were underway for it prior to the series' abrupt end.

In September 1995, Warner Bros. Domestic Television Distribution began distributing the series for broadcast in off-network syndication.

Step by Step is an American television sitcom that aired for seven seasons. It ran on ABC as part of its TGIF Friday night lineup from September 20, 1991 to August 15, 1997, then moved to CBS, where it aired from September 19, 1997 to June 26, 1998. Patrick Duffy and Suzanne Somers star as single parents, each with three children, who spontaneously marry during a Jamaican vacation after developing a budding relationship while Frank is Carol's client, resulting in their becoming the heads of a large blended family.

The series was created and executive produced by William Bickley and Michael Warren, and developed and executive produced by Thomas L. Miller and Robert L. Boyett. It was produced by Bickley-Warren Productions, Miller-Boyett Productions and Lorimar Television (the latter doing so from 1991 to 1993, when Warner Bros. Television assumed production responsibilities for it and Lorimar's other television series after shared corporate parent Time Warner consolidated the two production companies). The casting of Patrick Duffy fulfilled a contractual obligation that Lorimar made to give him a new show after his previous series, Dallas (which was also produced by Lorimar), had ended its run. It was created off of the idea of combining two of the most popular television stars from the 1970s known for their good looks (Duffy and Somers) to star as parents to attract adult viewers, with current teen celebrities (Staci Keanan from My Two Dads and Going Places, Brandon Call from Baywatch and Sasha Mitchell from Dallas) to star as their children to attract children and teen viewers.

In Australia, Step by Step aired on the Seven Network from 1991 to 1995 and on the Nine Network from 1996 to 2000. In 2011, Step by Step was acquired by 7TWO. In 2015, 111 Greats started airing the whole series.

When the series was casting its characters, child actor Jarrett Lennon originally landed the role of Mark Foster. Lennon had been chosen by the producers after guest starring in the last original episode of the Miller-Boyett series The Hogan Family, which was produced in late 1990. After shooting the original (unaired) pilot for Step By Step, Lennon was dismissed from the role of Mark, and the producers later replaced him with Castile (who had blonde hair like on-screen mother Somers, as opposed to Lennon having brown hair). Most of Lennon's pilot scenes were reshot with Castile, but during the first season, footage of Lennon remained in the show's opening title sequence. Lennon only appeared in wide shots with the Lambert/Foster family or, in the case of Suzanne Somers' credit scene, fleetingly appearing at the bottom of camera view as the kids huddled around Somers. All traces of Lennon were edited out by the second season. In 1996, these two actors had the tables turned on each other; Castile served as the original voice of Eugene Horowitz on the Nickelodeon animated series Hey Arnold!, but after a few episodes was replaced by Lennon, who voiced Eugene for the remainder of the show's first season.
