On the rear (south) facade is an attached one story structure that housed the men's jail cells. On its west facade the original steel and wood door is still extant and on its south facade there are three windows complete with metal bars. All of the jail building's windows and doors feature arched brick crowns, a theme repeating from the two-story portion of the structure. While the brick entablature and dentil work both reflect the main two-story building, the jail building lacks the overhanging eaves and brackets. The rear elevation of the main building has one second floor window.
