The houses are surrounded by a wall on three sides and can be accessed from the east. There are nine houses in total, four on the left and five on the right. Of these, the majority are ruined. Only two on the left and two on the right are intact and can be entered.
Entering the houses counts as trespassing. As of the newest patch, three of the four houses are occupied. 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. The house on the end, to the right, is not. There is an Average locked wall safe in the ruined house with the skeleton inside.

The Primm houses only appear in Fallout: New Vegas.
