The entrance to this four-story building is a blue metal door on the southeastern end of Lexington.
The stairs leading to the fourth floor and only accessible floor are trapped on the first floor with a landmine, and between the first and second floor by a tripwire and a grenade bouquet. Atop the stairs, two raiders are conversing in a two-room apartment. The first room contains a kitchen area, a sofa and a TV, and a bed. An explosives box is on the kitchen counter. The second room is on the outside, behind the blue metal door. It used to be a bathroom before its wall collapsed.
- Overdue book - On the top floor.
At the top of the staircase, there is a pile of bloody human remains. One of the two raiders can be overheard talking to himself, saying "It wasn't my fault, I had to do, what I had to do." Codsworth also comments that he doesn't even want to know what happened here.
The Lexington apartments appear only in Fallout 4.
