Series was based on a play of the same title by Christine Houston. It had been presented at the Crossroads Theatre and Arts Academy (Marla Gibbs's company) prior to being adapted as a series.
Sandra Clark was never intended to be a regular character. She was added to the cast after testing positively with audiences.
Mary Jenkins' birthday is June 14 (she cuts Lester off before he could say the year).
The entire address of the building in the show is 227 Lexington Place, Washington, DC.
This television series used the same set as Sesame Street. The 227 apartment building steps are the ones which usually stand beside Oscar the Grouch's garbage can.
Originally Jackée Harry auditioned for the role of Rose, when Marla Gibbs got her to play Sandra, instead.
If Marla Gibbs was unavailable to star in 227, then, it would've debuted the season after 1985, if The Jeffersons would've been on the air. When the show was unexpectedly cancelled in 1985, Norman Lear allowed Gibbs to star in the show.
Marla Gibbs's character was based on her character from The Jeffersons.
After gaining celebrity status, Jackée Harry, was at one point planning to leave the show to star in a pilot that has never been materialized, but left midway through the 1989-90 season, which was coincidentally, the final year.
A story line for the second season was considered in which Mary was to become pregnant, and miscarry the child at birth. Marla Gibbs said the idea was scrapped as the outcome would have been too much of a downer for a sitcom.
While the series was set in contemporary era Washington DC, the original play was set in 1950s Chicago.
Hal Williams, Helen Martin and Stoney Jackson had previously made guest appearances alongside Marla Gibbs on The Jeffersons.
Calvin lived with his grandmother Pearl because his Widower Father was an Air Force Officer stationed overseas.
One of the very few TV series set in Washington, DC not to center around any political or governmental themes.
Despite some rumours along with some controversy, Marla Gibbs said in an interview there wasn't any feud between her and Jackée Harry.
When acquiring rights to develop the play of the same name for television, Marla Gibbs original intent was to adapt it as a TV movie.
Co-creator/writer Michael G. Moye is credited under the pseudonym "C.J. Banks". Moye disagreed with the producers over the tone of the series and did not want his real name in the credits. "C.J." was the name of Moye's college theater professor.
