The houses are surrounded by a wall on three sides and can be accessed from the east. There are seven houses in total, four to the south and three to the north. Only four of the seven houses are intact and can be entered.
Entering the houses counts as trespassing. As of the newest patch, three of the four intact houses are occupied; the house in the northwest is not. As such, the Primm residents will warn the player to leave their house, and failure to do so quickly will turn all of the residents in the house into hostiles. There is an Average locked wall safe and a skeleton in the northwest house.
- A Sunset Sarsaparilla star bottle cap - In the southeast house, on top of a shelf.
The Primm houses only appear in Fallout: New Vegas.
