A new post office and court house was built in 1906 and the property was transferred to the city.

Although Mullett is officially listed as the architect, much of the design work may have been carried out by his assistant, William Appleton Potter, who specialized in the Gothic style.

[2] City Hall is built of brick faced with rough limestone blocks.

The exterior is detailed in an austere High Victorian Gothic style, capped by a mansard roof.
