The working title for this film was "Firehouse" after the Ghostbusters firehouse. In previous films, the exterior shots of the firehouse were filmed at Hook & Ladder 8 in the Tribeca (Triangle Below Canal Street) neighborhood of Lower Manhattan in New York City.
After filming was finished on
Ghostbusters II (1989), the firehouse kept half of the Ghostbusters II sign that hung outside. It was regularly displayed on holidays, particularly Halloween. Eventually, it was permanently moved inside, after a successful GoFundMe campaign by fans of the movie in June 2021, which funded a full-scale replica of the Ghostbusters sign. This sign now hangs outside of the firehouse year-round.
The GoFundMe campaign is now an annual fundraiser for the firehouse and a celebration is held there on Ghostbusters Day each year.
