The J. Edgar Hoover Building in (TXF: "Little Green Men")

The J. Edgar Hoover Building (also simply known as the FBI Building) is the headquarters of the Federal Bureau of Investigation. It was named in honor of FBI founder J. Edgar Hoover. (TXF: "The Blessing Way") The building's address was 935 Pennsylvania Avenue, Washington, D.C.. (TXF: "The Red and the Black", "Pilot")

The building was finished in 1974 and built on the site of the original FBI building. The building was open for public tours. (TXF: "The Blessing Way", "Monday")

Most of the top FBI officials worked there, including Assistant Director Walter Skinner and Deputy Director Alex Krycek. (TXF: "Tooms", "Within", et al.) The building also included a security detachment. (TXF: "The Blessing Way", "Pusher") In fact, access into the building, without express permission, was considered a crime. (TXF: "Pusher")

Roof & Exterior[]

The roof of the J. Edgar Hoover Building in 2001.

The building's roof in 2008.

In 2001, the roof was accessible from inside the building via both a set of stairs and an elevator. The stairwell access was a fire exit, to be used exclusively by authorized personnel only in times of emergency. (TXF: "Essence")

In 2001 and 2008, a helicopter pad could also be found atop the building. (TXF: "Essence", The X-Files: I Want to Believe) Several differences between the layout of the roof did take place between 2001 and 2008, however; in 2001, the building's roof included many ventilation shafts and several communication dishes, but these were gone by 2008, when the roof was virtually featureless apart from the helicopter pad and several offices that were built above the majority of the building. (TXF: "Essence", The X-Files: I Want to Believe)

In 2001, while a helicopter was stationed on the landing pad, alien super-soldier Billy Miles followed Assistant Director Walter Skinner on to the roof, with Skinner having taken the elevator and Billy Miles taking the stairs, but Miles was unaware that Special Agent Fox Mulder had accompanied Skinner up to the roof and Mulder pushed Miles off the side of the building, as a garbage truck was passing below. (TXF: "Essence")

In 2008, former agents Fox Mulder and Dana Scully arrived on the roof in a helicopter and were greeted by Special Agent Drummy. (The X-Files: I Want to Believe)


Entrances and Exits[]

Front Door[]

A security checkpoint at the building's front door in 1995.

The public entrance to the J. Edgar Hoover Building featured a security checkpoint, including a walk-through metal detector. The floor in front of this metal detector, on the side of the entrance from which members of the public would enter, was emblazoned with a large FBI seal, over which hung a flag of the United States of America. A desk to the right of the detector, from the perspective of the entrance, included a computer and a small rectangular sign that read, "All Visitors Must Pass Security Before Entering the Building". A small, plastic, rectangular dish sat on a platform between the desk and the nearest side of the metal detector. Opposite the desk, on the other side of the detector, was another work area. A space between this area and a nearby, adjacent wall allowed FBI personnel to come and go as they pleased, without having to step through the metal detector. On the other side of the security checkpoint from the entrance was a metallic door for an elevator that had only two small controls on the door-frame. (TXF: "The Blessing Way")

During normal procedure, several security guards were stationed at the metal detectors, the guards and the detectors themselves insuring that the building remained safe at all times. Tours would generally start here, and FBI personnel would be able to gain entrance by having their badges scanned. (TXF: "The Blessing Way") The daily goings-on of this security entrance were regularly recorded on surveillance video tape. (TXF: "S.R. 819")

The simplistic security entrance in "The Blessing Way" and its busier equivalent in "Pusher" and "Talitha Cumi" could be assumed as being two different areas. The security guard manning the guard desk in "The Blessing Way" refers to that simplistic security entrance as "the front door" and, in "Nothing Important Happened Today II", The Lone Gunmen's Langly uses this same phrase to refer to an entrance to the FBI building that does not appear in the episode, suggesting that the same area as can be seen at the time of "The Blessing Way", set in 1995, still exists in 2001, when "Nothing Important Happened Today II" is set. Script sources refer to both the entrance area in "The Blessing Way" and the busier equivalent in "Pusher" and "Talitha Cumi" both as the "lobby", suggesting that they were meant to be the same area.
Granville Square in Vancouver was used to film the lobby of the FBI building in "Pusher" and "Talitha Cumi". Before this location was decided upon, scouting of a possible location for use as the FBI lobby in "Pusher" presented a challenge to the production crew since, in reality, the J. Edgar Hoover Building bears no resemblance to anywhere in downtown Vancouver, where the first five years of the series were almost entirely filmed, and because most lobbies were either too cramped or poorly laid out for filming purposes. The location, although it was a smaller version of the real place, was also chosen due to its believable sense of entry when viewed from certain angles. At the time of production on "Pusher", Granville Square, located at 200 Granville Street, housed numerous high-profile tenants but, luckily for The X-Files' production crew, the ground floor offices were vacant and accessible to the crew's art and lighting departments.

Main Concourse[]

The building's main concourse, with the street level entrance towards the back.

Flags in the main concourse, between the street-level entrance and the reception area.

The reception area of the main concourse, near a row of elevators.

In 1992, a concourse was located on the ground floor which allowed access to the building. The room featured a reception area where visitors and members of the FBI would report to a receptionist after entering.

Two streets ran adjacent to the concourse and could be seen from inside, through two transparent walls that separated the room from each street. An entrance or exit was built into each wall; a set of transparent double-doors provided access from the same level as the street, while the other entrance was lower than the room with several steps leading up to it.

A third, marble wall faced the lowered entrance, between the receptionist's desk to the left and the street-level double doors to the right. A plaque of the FBI seal was displayed on the wall between two flags, one for the United States of America and the other for the FBI. The flags stood alone in front of the wall.

At least four elevators could be found in a recess between the receptionist's desk and the marble wall. These allowed access to the rest of the building and their interiors were lit with a green-shaded light.

The receptionist's desk was wooden and had a small raised platform between the receptionist and the rest of the room. On the receptionist's side, a horizontal panel allowed space for paperwork.

A wooden bookshelf sat in the opposite corner of the room, against the wall where the street-level entrance could be found.

The roof was white and had a repeated decorative motif showing indented circles within squares. (TXF: "Pilot")

The main concourse, as it appeared in the pilot episode, never appeared again. The main reason for this was that, when The X-Files crew shot the pilot episode, they used a totally different set to the rest of the series. Because Chris Carter and other production personnel were unsure if the pilot would be the only episode made, they had no reason to arrange a permanent studio in Vancouver. It was only after 20th Century Fox ordered more episodes that the production personnel established a studio, where later scenes inside the J. Edgar Hoover Building could be filmed.


Bullpen Hallway[]

The bullpen hallway was an open, busy and crowded work area occupied by FBI officials and situated on the way to Chief Scott Blevins' office from the main concourse. (TXF: "Pilot") This work area existed as early as March 1992, although it was akin to a modern version of a large, open-area work room that could be found in the original FBI Headquarters. (TXF: "Pilot", "Travelers") In 1993, a desk in the bullpen hallway was where Agents could requisition a car, from either a woman named Doreen or another woman named Fran. An Agent Finley also worked in the bullpen hallway in 1993, at least temporarily. (TXF: "The Jersey Devil")

Chief Blevins' Office[]

Section Chief Scott Blevins' office in 1997.

One of the offices in the J. Edgar Hoover Building belonged to Scott Blevins. (TXF: "Pilot", "Redux") He had this office in March 1992, at which time he was a Division Chief and his rank was displayed on a sign on the outside of his door. (TXF: "Pilot") He remained in this office until four years later, by which time he had become a Section Chief but there were no signs affixed to his door. (TXF: "Conduit", "Redux")

In a line from an early revision of the pilot episode script, Division Chief Blevins' office is established as being on the third floor of the building, in the violent crime division. However, such a precise indication of the office's location is not provided in the final version of the episode.

Deputy Director's Office[]

Deputy Director Kersh's office in 2000

When Kersh was promoted to Deputy Director, he moved upstairs to a more elite and bigger office. (TXF: "Within") This office was on the building's fourth floor. (TXF: "Existence")

Assistant Directors' Offices[]

AD Walter Skinner's office in 2000.

One of the offices in the J. Edgar Hoover Building belongs to Assistant Director Walter Skinner. (TXF: "Tooms", et al.) Kersh had a similar office in the building, while he was an Assistant Director from at least 1998 until 2000. (TXF: "Drive", "Within", et al.) AD Kersh's office was on the third floor of the building. (TXF: "Triangle")

Personal Assistants' Offices[]

The assistants to the Assistant Directors and Deputy Director would often have an adjutant office outside in order to screen guests and visitors. (TXF: "Dreamland I")

Basement Office[]

The X-Files office in 2016

Many offices were on a level below the first floor, including an office where the FBI kept a copier. (TXF: "One Breath") In 1992, Fox Mulder was assigned to the office and took the X-Files with him. The office included several filing cabinets, including one where the X-Files were stored, and a desk. Mulder cluttered this office with paraphernalia relating to the paranormal, including a UFO poster proclaiming "I Want to Believe" that Mulder obtained in a head shop on M Street prior to March 1992. (TXF: "Pilot", "Chinga") In 1994, the office was closed and each item of furniture in the room was covered in plastic wrapping. (TXF: "Little Green Men", "3") This was removed when Mulder returned to the X-Files, and the office, several months later. (TXF: "3")

The office was totally destroyed by fire once in 1998. (TXF: "The End") The room was subsequently redecorated, shortly after the office was assigned to Agents and Diana Fowley later in 1998. This redecoration was a lot barer and more darkly lit than the room had been when Mulder and Scully had been working from the office. (TXF: "The Beginning") After Agent Spender voluntarily packed up his office, the room, and investigation of the X-Files, was reassigned to Mulder and Scully, and the office returned to its earlier cluttered appearance. (TXF: "One Son") Mulder acquired a replacement poster stating "I Want to Believe" that was almost identical to his previous one and attached it to the same wall. (TXF: "Alpha")

In 2002, the office was completely emptied, however, with the exception of this poster, which was left lying on the room's floor. (TXF: "The Truth") By 2008, the cluttered look of Mulder's former office had inspired the appearance of his home office in rural Virginia, even including his "I Want to Believe" poster. (The X-Files: I Want to Believe)

People who operated out of the Basement Office:

Seemingly, Mulder was temporarily assigned, in 1993, to a different office that was located near the bullpen hallway but was almost identical to his basement office at the time. Evidence of this can be seen in TXF: "The Jersey Devil", wherein Mulder and Scully continue a conversation while walking from the office to the bullpen hallway. Presumably, Mulder was assigned to this office after "Squeeze", in which the two agents talk about themselves being "down here" due to the FBI. Despite the on-screen evidence, the change of office is not established in "The Jersey Devil"'s script.

Corridors & Hallways[]

A corridor leading from an elevator to Walter Skinner's office.

A corridor of the building in 2008.

The vast corridors in the Hoover Building helped connect offices. They were used often by tours and FBI personnel alike. (TXF: "Triangle") In March 1992, a narrow corridor allowed access to and from Division Chief Scott Blevins' office. (TXF: "Pilot")

The script of pilot implies that this "hallway" is on the third floor of the building, in the violent crime division.

Other narrow corridors were situated on the basement, one of which led from an elevator to the basement office on the left. (TXF: "Pilot")


There was at least one elevator in the building, with a single set of double elevator doors on the basement near the X-Files office. (TXF: "Pilot", et al.) This elevator was used by Agent Scully upon her first visit to the basement office in March 1992. (TXF: "Pilot")

The elevator itself does not appear in the pilot episode, only one of the double doors as it slides open to allow Scully passage to the X-Files office for her first visit there.

Other Rooms and Departments[]

Observation Room[]

An observation room in the building consisted of two compartments, separated by a mirrored window. In March 1992, this room was where Billy Miles underwent hypnosis, under the supervision of Heitz Werber and observed by Mulder, in the same room, and by Scully, Blevins and a Third Man, from behind the mirrored window. (TXF: "Pilot")

FBI Library[]

In an FBI library, Dana Scully does some research.

An FBI library in the organization's headquarters included a microfiche projector. In 1992, this room was darkened as Scully sat alone, using the microfiche to find an article pertaining to the attraction of Ellens Air Base for UFO buffs. (TXF: "Deep Throat")

Evidence Room[]

Since the Bureau is the primary investigative agency for the US Department of Justice, it stands to reason that they would have a massive evidence room. While evidence is generally kept at the FBI Academy at Quantico for analysis, it could be sent to the Hoover Building for detailed analysis from the various sections. (TXF: "Grotesque")

OPR Hearing Room[]

One of the rooms at FBI Headquarters was used by the organization's Office of Professional Review in 1998. (The X-Files Movie, TXF: "The Beginning")

The script of TXF: "The Beginning" establishes that the OPR room in that episode is intended to be the same as the one in The X-Files Movie.

Conference Room 5[]

Inside Conference Room 5

In 2008, one of the building's rooms was used by agents involved in a search for Agent Monica Bannan. (The X-Files: I Want to Believe)

A sign on the door to this room identifies it as "Conference Room 5".

Background Information[]

An animated version of the J. Edgar Hoover Building.

A sketch of Mulder's office used in its creation.

Mulder's office at the Hollywood Entertainment Museum.

The same shot of the J. Edgar Hoover Building's exterior, with a jogger running past the camera, was used in both "Pilot" and "Lazarus".

It is unclear whether a room in which Scully types a report in the penultimate scene of "Deep Throat" is the basement office or not, as the scene does not appear in the episode's script and the room seems quite different from the X-Files office. A legend that appears over the scene establishes its setting as the J. Edgar Hoover Building, however.

An animated building resembling the J. Edgar Hoover Building appeared in The Simpsons episode "The Springfield Files" with tagline "FBI; DIVISION OF PARANORMAL ACTIVITIES; WASHINGTON, D.C." and Mulder's X-Files office also made an appearance in the episode.

The set used to film the basement X-Files office is preserved at the Hollywood Entertainment Museum. [1]
