New York City Hall is the chief administrative building of the City & County of New York.
Primary Canon HistoryEdit
In 1984, the Ghostbusters were brought to City Hall to speak before Mayor Lenny and several other government officials about the impending Gozer Incident. The Mayor sided with the Ghostbusters and had Walter Peck removed. The Ghostbusters departed from the hall's loading dock with a police escort and the National Guard.
Secondary Canon HistoryEdit
A couple days before the appearance of Idulnas, the Mayor and several city officials held a meeting with Walter Peck at City Hall. In order to keep the Ghostbusters in check for the best interest of the city, the Paranormal Contracts Oversight Commission was reinstated. Its temporary office was to be established in the Department of Public Safety.
In mid-June, Peck was summoned to the Mayor's office to discuss the Ghostbusters' trip out of state. The Mayor was irate at the prospect of the guys being gone during summer, the height of a tourism influx, but Peck revealed the city would be making a handsome commission from all jobs incurred. In the fall, Peter had an unscheduled appointment with Peck to discuss the Ghost Smashers. In May of the next year, Peck met with the Mayor and Deputy Mayor, Ms. Stone to discuss the surge of ghost-related complaints, the missing Ghostbusters, and the new Ghostbusters.
City Hall praised Walter Peck for having so many Ghostbusters on hand to deal with the supernatural activity surrounding Tiamat's presence... even though he had nothing to do with it. A few days into the dimensional bleed incident, a press conference was held at City Hall. The Mayor and Peck downplayed any impending doom and the dangers of the spatial anomalies like the two Statues of Liberty. Peck assured the press that the Ghostbusters were already handling the greater-than-normal influx of ghosts from the phenomenon and dealing with the situation.
- Filming was done at the actual New York City Hall for two days.  
- The Mayor's office scene was shot in City Council President Carol Bellamy's office on the other side of the building where the actual Mayor's office was. Both were identical in design. 
- In the Ghostbusters commentary track, Joe Medjuck misremembered the office used as Elizabeth Holtzman's. 
- Filming at the City Hall was not a usual occurrence. 
- In a variation of the Mayor's office scene, Ray called Walter Peck 'wee wienie winkie' and Bill Murray broke up completely - a rare occurrence he almost never does. 
- In reality the City Hall loading dock doesn't exist. The location used was a building across the street from the real City Hall. 
- In Ghostbusters #9, page one, panel two, obscured by the Mayor's word balloons on the left side, is the painting "Gainsborough's Blue Boy," in reference to Ghostbusters II, when Janosz Poha compared Vigo to it.
- On page 6 of Ghostbusters 101 #3, in panel 1, the ticker at the bottom of the screen mentions City Hall.
