The Warehouse  (also known as Ghostbusters Warehouse Facility) is a building used as storage by the Ghostbusters for their vehicles, such as the Ecto-Gyro and Marine Ecto-8. It is located in Red Hook, Brooklyn. 
After Peter Venkman was asked by Walter Peck to quickly deal with the John Milton, Peter called up Ray Stantz, who was at the Warehouse. Ray went through a standard pre-trip check and declared Ecto-8 was seaworthy. After about a hour, Peter arrived at the Warehouse with Kylie Griffin in tow. After suiting up, the trio left with Marine Ecto-8 and took it to the launch. In January, just after New Year's Eve, Egon Spengler and Ray took the five Traps containing Rodefhiri to the Warehouse. They placed each Trap in a crate and filled them with cement to protect against accidental release.
During ongoing repairs at the Firehouse, the Warehouse served as the Ghostbusters' temporary office. After they defeated the Sandman, the Ghostbusters gathered at the Warehouse. Ray talked about his initial observation of ivory on the Pearson's door frame when they were first put into a dream state. He cleared Egon who only suffered a cut under an eye. Ray then shared his findings on the Sandman. It was evident they didn't stop it permanently and Egon and Ray needed to conduct more research. With that, Egon fell asleep. When Janine Melnitz returned from Tokyo, she set up shop at the Warehouse. She was not happy to be stuck with stacks of unfinished and unfiled paperwork. While the Ghostbusters investigated a call from the United Nations Building, Jenny Moran paid a visit to Janine at the Warehouse. Janine informed Jenny of her plight. Jenny implored her start looking to hire more help. Janine couldn't believe her at first then hugged her.
The Warehouse was chosen as the site to host Peter's Ghostbusters 101 idea where paying customers could experience being a Ghostbuster, from learning about various entities to busting a ghost in controlled conditions. A giant ionized glass cube enclosure was constructed in the Warehouse. In the next couple of weeks, the pilot 101 team were given tasks akin to an internship. Evan Torres found himself at the top of the plane in the Warehouse and used a sweeper on dust that piled up. Jenny and Ray presided over a 101 session with a cadet named Ms. Zeigler. Ray was called away to Ray's Occult to authenticate a collector's item. Jenny continued to coach Zeigler on capturing a Soar Throat Ghost in the enclosure. Jenny eventually acknowledged Cait Banner's look. Cait pointed out they were being treated like interns - slime detail, dust duty, and running errands left and right. She wanted to know when they were going to be taught ghostbusting again. She suspected it was because they weren't paying customers. Jenny snapped and reminded her of the teleportation unit incident. Jenny was interrupted by a call from Janine. She told Jenny to call Ray while she notified the others of an emergency at Battery Park, twin Statues of Liberty on Liberty Island. Jenny told Cait to let Zeigler out in the meantime.
After Abby Yates and Egon collected data at City Hall Park, he concurred with Abby's assessment and stated they needed more information. Meanwhile, the pilot team went home for the night and left the Warehouse. Jenny got a call from Egon asking about the team. She recalled Ray still had a class scheduled the next day. She asked if something was up. Egon replied "yes" and hung up. Jenny told Elaine no one could take samples of Psychomagnotheric Slime home. She put the jar back where she found it.
Egon and Donatello went to the Warehouse to use the ionized glass enclosure to test their prototypes. Egon cautioned Donatello the glass may not be able to withstand too many hints from his Proton Weapon.  He opened a Trap into a slot and released a Mouth Critter Ghost into the enclosure with Donatello. Donatello asked Egon to humor his request and talk about what it was like being dead. Talking while fighting was something he did with his brothers and found it comforting. Egon answered then asked about what he meant by his soul being in two places. Donatello explained the details of his death then managed to hit the ghost with his proton-powered staff. The ghost retaliated and knocked him across the enclosure. The force and Donatello's shell made a crack in the glass. Donatello decided to try the Trap-Gate but soon realized they miscalculated the power needed. Egon grabbed the Trap but remembered there was a safety in place that kept the door locked to keep any active ghosts contained.  He asked Donatello to stall but noticed he sounded like Winston again. Egon instructed him not to let himself drift then asked him to continue with his story. Egon ripped out several red wires and unlocked the door. He threw out the trap and recaptured the ghost. Egon concluded they had to boost the Trap-Gate's power considerably then inquired if he ever felt guilty about coming back. Donatello replied he shouldn't but admitted he did. They rushed back to the Firehouse to do their final modifications.
