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.
Two days after Peter regained consciousness, a gathering was held at the Warehouse. The Ghostbusters, Janine, Kylie, Jenny, Kevin Tanaka, Special Agent Melanie Ortiz, and the Chicago Ghostbusters (Rookie, Ron Alexander, Dani Shpak, and Lou Kamaka) met with nine teams from parallel dimensions: the Ghostbusters of Dimension 68-Q, Mike the Golem and Robo-Buster of 68-V, the Ghostbusters of Dimension 68-M, the Ghostbusters of Dimension 11-W, the Ghostbusters of Dimension 50-S (Alan Crendall, Gabriel Sitter, Bridget Gibbons, and Samuel Hazer), The Real Ghostbusters of Dimension 68-R (Egon Spengler, Peter Venkman, Winston Zeddemore, Ray Stantz, and Slimer), the Extreme Ghostbusters of Dimension 68-E (Kylie Griffin, Eduardo Rivera, Roland Jackson, Garrett Miller, and Slimer), the Ghostbusters of 80-C (Jillian Holtzmann, Patty Tolan, Erin Gilbert, Abby Yates, and Kevin Beckman) and the Ghostbusters of Dimension 35-N. Egon briefed them about the current situation---several entities were taken out of the Containment Unit at once and dispersed into various dimensions through the Interspatial Teleporation Unit---and the stakes, they had re-capture and return all the entities back into the Containment Unit then recalibrate it in time or else there would be a structural collapse followed by an explosion.
Ray was about to go over the equipment but Gabriel Sitter spoke up. Samuel Hazer asked why they didn't just use the teleportation unit to go back in time and prevent the entire incident from happening. Ray tried to explain it wasn't a time machine but Kylie Griffin and Eduardo Rivera, of the Extreme Ghostbusters, pointed out they were trained by Egon Spengler, an older version of the Egon from The Real Ghostbusters, who was perplexed. Roland Jackson believed that was proof of an element of time travel. Alan Crendall pointed out his team was from the prime team's future and didn't get why the Ray he knew didn't warn them beforehand. Janine heard enough and whistled. She yelled at everyone to listen, shut up, and pay attention. Egon reiterated the teleportation unit could not time travel but time was a dimension they could access in so far as they went to parallel realities that could be further ahead or further behind what they knew as the present but no action they took had an effect on their timeline. Before Ray could continue, Melanie triggered the alarm. She was alerted about a P.K.E. spike at the George Washington Bridge and took Winston, Jillian Holtzmann, Rookie, Lou Kamaka, and Dani Shpak. Holtzmann left her headset on channel one and their bust came through the Warehouse radio. Kevin Tanaka listened to all of it while Egon explained the functions of the Remote Portal Access Band. Some screams interrupted him. Egon requested someone to turn the volume down. Kevin apologized. Erin Gilbert asked if they should go and help the field team. Egon was probably sure they were fine and continued. He moved on to the Trap-Gates and using them to send an entity directly into the Containment Unit. The 101 Pilot team was tasked with watching over the teleportation unit's controls under the supervision of Egon Spengler of Dimension 68-E, the mentor of the Extreme Ghostbusters.
After the field team consisting of Mike the Golem, Robo-Buster, and the Ghostbusters of 35-N recaptured the Bone Dragon, they returned to the prime dimension. Back at the Warehouse, Robo-Buster informed Egon 68-E they exhausted their supply of Trap-Gates and required more. Egon 68-E wasn't sure it was good idea for them to deploy again and informed them of a massive spike that affected the portals and reports from the other teams that their rosters were shuffled around. Mike asked Egon 68-E to give him a task so he could help, but Egon 68-E wasn't so sure there was a way for them to. Kevin Tanaka noticed one of the lights turned on. Zoe told him it meant the teleportation unit was about to activate. Kevin wondered if that meant everything was okay. Egon 68-E concluded they were worried about nothing. Mike noted the field teams managed to return the bulk of the escaped ghosts, further breaches were contained, and Peck seemed to have relaxed. Mike declared he loved it when everything was in order. Ron fell through the portal. Egon 68-E realized he was injured. Mike kicked himself for jinxing it and examined Ron. He didn't think the wounds were too deep but still they were still in danger of getting infected. Kevin noticed something alarming on the panel. Mike took a look and confirmed something was wrong. All of the tracking devices were reading like they were in the same dimensional location. He wondered how all these glitches were even happening.
The Interspatial Teleportation Unit activated and the field teams returned starting with Peter declaring the conquering heroes had returned. He noticed Egon 68-E was wearing their merchandise and hoped he already paid for it. Ray asked how long they were gone. Egon 68-E told him it was about six days since their last communication. Ray was satisfied and declared they pulled off a miracle. Kevin Beckman answered the phone and handed it off to Ray. Despite the ghosts recaptured and the ghosts captured by the fill-in teams, the Containment Unit was still on the verge of total meltdown. With no other choice and no time left, Jenny sacrificed herself and went into the unit to stabilize it. Ray lost Jenny at 5:31 pm. He remembered Tiamat's final threat cursing them and Rachel Unglighter's warning there was always a price for dealing with gods. Overcome with anger, Ray shot the teleportation unit. Holtzmann objected but Peter asked if she heard what just happened then reckoned Egon could fix it in a couple of hours. Egon claimed less. Holtzmann rescinded her panic then reminded Ray about the Containment Observation TV he and Egon were working on.
