Historic US Commissioner's Residence at Yellowstone

The Commissioner's office was the first stone building erected at Fort Yellowstone and included an office, jail, and residential space on the first floor and bedrooms upstairs. The one-and-a-half-Story, rock-faced ashlar sandstone building stands by itself near the Hot Springs terraces. The building has a rectangular plan and a stone foundation. The gable-on-hip roof is covered with wood shingles and features two interior stone chimneys. The majority of the windows are one-over-one-light double-hung sash.

The front (northeast) features a full-width open porch with a hipped roof supported by six square posts that is accessed via a set of wood stairs. The entrance, which has a paneled and glazed door, is centered inside the porch and flanked by two windows. There are two front shed roof wall dormers, each with a single window. The southeast wall has an off-center entrance flanked by windows and two shed roof dormers. The rear (southwest) has an off-center entrance, three small windows that correspond to the location of the jail cells, and two through-the-cornice shed roof dormers. The northwest wall has two windows on the first story and two shed roof dormers.
