The living quarters are available at the start of the game. They increase the number of vault dwellers that can reside in the vault, and also allow the player to breed new dwellers. When three merged living quarters are fully upgraded, the room is able to have themes applied to it.
Male and female dwellers placed together within the living rooms have a chance of making babies and increase your vault population, as long as they are unrelated. They will talk at first, then dance, and eventually rush into the bedroom to make the female dweller pregnant. How long this takes depends on the Charisma stat of the dwellers. You must be actively playing for the last step to occur. Pregnancies last for three hours, and it takes three additional hours for the child to become an adult.
During an incident, pregnant dwellers, children, and pets will hide in living rooms until the threat is cleared.

Female dwellers can glitch into a permanent pregnant state; suspected to be caused by removing the room they conceived in before giving birth.[verified] - Fixed in version 1.0.3 for iOS.
- Version 1.4 for Android OS (on an ASUS Zenfone 5): Newly impregnated dwellers may emerge from the bedroom impossible to pick up. This may be fixed by closing and re-opening the app. Likewise, if an incident causes them to flee, once the incident is over and they return they will once again be able to be picked up.
- In version 1.6.1 for PC, players were able to mouse-over silhouettes of dwellers "mating" in the living rooms behind the wall. It has been disabled in the recent updates.
