The first building used for a courthouse was a building owned by The Church of Jesus Christ of Latter-day Saints.^[1] It was a large two-story log structure on South First Street. The county then rented space for their use until a courthouse was completed in 1868. The property had been acquired two years previous with construction starting the same year. County offices were located on the first floor, court functions on the second, and a jail was located in the basement. That structure became unsafe and was replaced by a stone Beaux Arts-style building in 1888. Voters gave their approval of the project on March 10, 1885. The county rented space in the Masonic Temple during construction. The building was constructed for $141,800.^[2] It too became unsafe and it was replaced by the present Modernist structure in 1977.

The five-story brick structure was designed by Hollis and Miller and built by A. Borchman Sons Company. Vertical brick piers divide the building into bays on the lower floors. They are composed of white concrete. The main entrance is recessed on the east elevation. It is located on the same square as the two previous courthouses.
