Grundy County has one of the newest courthouses in the state. The previous courthouse was built in 1885, but was burned by an arsonist on May 3, 1990. This new courthouse was opened in April 1996. It's a two story brick building with a projected pedimented portico front entrance. There is also a low hip roof with a center octagonal cupola. Directly in front of the main entrance is tree-lined Pelham Rd.
