The Renaissance Revival style building was designed by Jasper N. Preston and F.E. Ruffini in 1883.
The courthouse is a three-story, stuccoed brick, structure with a copper-domed clock tower in the center of a flat roof. Originally, the building was not stuccoed. The stucco was added in a remodeling in 1924. Also at this time, the dome was lowered and various architectural details were removed giving the building a Neoclassical look
