The Living Quarters are unlocked by default. Living Quarters increases the number of vault dwellers that can reside in the Vault, it also allows you to breed new dwellers. Male and female dwellers placed together within the living quarters have a chance of making babies and increasing your vault population which is why it is one of the facilities available at the start of the game.
Two dwellers of different sexes will talk and (if they are not family members) eventually dance, followed by rushing to 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 3 hours, and it takes 3 additional hours for the child to become an adult.
During an incident, pregnant dwellers, children and pets will hide in living quarters 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, player was able to mouse-over silhouettes of dwellers "mating" in the Living Quarters behind the wall. It has been disabled in the recent updates.
