A co-op, housing fourteen students in two singles (one of which goes to the HLEC) and six doubles, all on the second and third floors. The dining co-op on the first floor feeds 85 students. Old B is the only housing co-op that does not reserve spaces for first-years.
Traditionally, the housing co-op was all female. This changed after the spring semester of 2002, and now every spring, the first eight women and transgendered people let in decide whether the co-op will be gender-neutral or restricted to women and transgendered people, and the rest of the spots are filled accordingly. The house has been all-gendered every year since then except 2004-05, 2009-10, and 2010-11.
In the spring of 2010, the OSCA Board of Directors passed a proposal to turn the Old B Triple into a double, reducing Old B housing membership to 14.
Along with J-House, Old B is one of the two farthest south buildings on the Oberlin College campus; there are approximately two blocks between these buildings and the next nearest Oberlin College building, Russia House.
Old B has a reputation for being filled with angry women. It also has a reputation for being full of extremely quiet, boring women. This is all pretty much bullshit.
