The original first floor layout contained room for the police station, fire station and, in 1891, the library. The building's vault was, and is, located near-center of the first floor. The original fire station occupied the entire east half of the building. At the rear (south) elevation is a one-story attached structure with its own entrance. It housed the jail cells in the original building and two cells are still intact. The entire second floor in the original 1884 floor plan was occupied by a meeting room save space for two small closets and the stairwell.
