This house in the city's infield (near the intersection of First and Second Streets) consists of two main sections: a small storage room with stairs leading up to the sleeping area to the left, and a living area through a short corridor to the right.
Just outside, adjacent to the house to the east, is a Novice-locked warehouse used for stocking general supplies. It contains various containers and minor loot.
Earl Sterling's house key is needed to enter the house without lockpicking the Novice-locked door.
Earl Sterling's house only appears in Fallout 4.
