The Family Cabin Historic District consists of 16 contributing properties: 13 log cabins, one lodge, and two latrines. Cabins 1–12, half with one room and half with two, are in a line along a road, similar to 1930s motor courts. The cabin layout at Black Moshannon State Park is unique compared to CCC-built cabins at other Pennsylvania state parks. The cabins at the other parks reflect the "rustic" style of cabin layout promoted by the National Park Service. The Lodge, also known as Cabin13, is a large rectangular clapboard-sided building with a stone fireplace, while Cabin14 is L-shaped with an open porch. Two pit latrines built by the CCC were also contributing structures.
