Vault 21 is a Vault-Tec Vault that was once hidden under Las Vegas, Nevada. It has since been converted into a hotel/casino and acts as one of many sources of income for Mr. House and his young New Vegas empire in 2281.[Non-canon 1]


Located in downtown Las Vegas, Nevada, Vault 21 was one of the few Vaults that successfully protected its inhabitants while fulfilling the parameters of its experiment. Everyone in the Vault was equal, it was created with a perfectly symmetrical layout, and all conflicts and problems were solved through gambling.[2] Chosen representatives gambled against each other in the main atrium and the winner earned the right to settle the dispute as wished by the collective.[2][3] Sarah describes it as "pure New Vegas" as "everyone has a chance and lady luck smiles if you play your odds right."[3]

In 2274, Robert House contacted Vault 21's residents with an offer of inclusion in the resurrection of Vegas. While most of the Vault dwellers wanted to refuse the offer, some residents were in favor of it. As a result, residents in favor of Mr. House's offer challenged each level's representative who was in favor of staying isolated. After a game of Blackjack that lasted for many hours, those in favor of opening to the outside won in an extremely risky move. Soon after, Mr. House ordered the Vault to be filled with concrete.[4][5] But at the request of Sarah and Sheldon Weintraub, he left some of the upper levels intact and allowed Sarah to establish a hotel there, which became another source of income for Vegas's growing economy.[5] After their emergence, many of the Vault dwellers went on to live new lives in the outside world, such as Doc Mitchell.

A Vault door sign advertises the hotel, on the western end of the Strip, "Vault 21" emblazoned with neon lights. The Vault entrance is an above-ground building that opens to a lobby serving as a gift shop. It is run by one of the only Vault residents to have remained, Sarah Weintraub, who runs the establishment and utilizes a terminal network to communicate with patrons.[6] Stairs lead from the gift shop down into the Vault.

There is a central atrium with two Blackjack tables, a hallway with living quarters, including Sarah's room and a guest room that the player character can rent. Another door leads to the cafeteria/diner. The lower levels were filled with concrete by Mr. House and are inaccessible except for the maintenance level, which is accessible from the basement of The Tops.[5] This level consists of a long hallway with a few small rooms branching off of it. The elevator in Benny's suite leading to it is locked unless he is attacked in the Tops presidential suite, and the tunnel ends in another locked door.

Behind the scenes

  • Vault 21 was designed by Jorge Salgado.
  • Vault 21 is geographically situated in the same real world location as the former Las Vegas Hilton, now Westgate Las Vegas, which contained a municipal fallout shelter in real life.[Non-canon 2]
  • Josh Sawyer stated that House cemented the Vault to avoid former residents from retaking it, keeping it limited to a tourist attraction and small-scale residence.[Non-canon 3]
  • Vault 21's lower levels being filled with concrete is a subtle reference to the Silver Slipper Casino, as it was rumored that the mechanized slipper at the front of the casino was filled with concrete by Howard Hughes, the man who was the basis for Mr. House.
  • James Garcia created the 3D model of the neon sign letters.[Non-canon 4]
  • The computer in Sarah Weintraub's room contains an email from a Charlene Tann who mentions her husband Biff Tann.[8] This is a nod to the Back to the Future trilogy, in which the antagonist is named Biff Tannen.
  • The Vault guest terminal advertises pool sets in the gift shop with the line "Hustle it like Minnesota Fats!" This is a reference to the novel The Hustler by Walter Tevis and its 1961 film adaptation, starring Jackie Gleason as Fats.

    Sarah Weintraub: "Well... it is my vault, all right. I mean, yeah. That is, no. I take care of it but I suppose you could say that it belongs to Mr. House."

  2. 2.0 2.1 Sarah Weintraub: "All right! Please, follow me. We'll head into the vault right away. This bunker protects the entrance to the vault - solid stone outside and thick steel on the inside! Above us there's the control center for this level of the vault's life-support systems, electric grid, radioactive shields and all that jazz. Don't get lost! My vault has many corridors and rooms - although it is no longer symmetrical, after Mr. House threw us out. This is the main game-hall. Here we settled the big disputes among the vault's levels. Chosen representatives gambled against each other here. The winner earned the right to settle the dispute as wished by the collective. We used to have such parties in this diner! A bitch to clean later... but well worth it! This hall leads to our guest rooms. You can use the first room on our left. But no snooping next door! That's my room, always was. Down there is the game room! Each side of the vault had one... but the other is filled with concrete now. Okay, that wraps it up. I'll see you soon!"

  3. 3.0 3.1 The Courier: "What is so special about this vault?"
    Sarah Weintraub: "My vault is pure New Vegas. Everyone has a chance and lady luck smiles if you play your odds right!... Okay, it was like that before we had to leave. Vault 21 had very smart ways to help people get along. All arguments and fights got solved through gambling. I'll give you a quick tour of my home! Oh, yeah, if you like."

    A vault where its dwellers used to settle their differences via games of chance, is now hotel and gift shop. The top floor is just the gift shop and front desk for the hotel. Visitors can buy Vault 21 jumpsuits, toasters, and other souvenir items, and view displays and read authentic details about the history of Vault 21. The vault itself is in pristine condition, aside from the subterranean eastern section, which was sealed by Mr. House; much to the annoyance of the last remaining residents Sarah (and her brother Michael) Weintraub. Aside formIn-game spelling the ostentatious signage, the initial kiosk welcoming visitors to the vault lacks the spectacular nature of The Strip's other venues. But step inside, and you're transported back in time."

  3. Formspring January 2, 2012:Why in the world would House cement in that Vault? It makes no sense.
    Joshua Sawyer: He doesn't want it to be able to return to a fully-functional vault because he doesn't want its former residents to attempt to retake it. I.e. he wants to motivate the Vault 21 dwellers to leave the area. If he had simply sealed off areas or electronically locked portions of it, enterprising smarties like ex-vaulters might attempt to work against him and eventually restore it. With the majority of the vault filled with cement, it can only function as a tourist attraction and small-scale residence.
