In addition to the county constitutional offices and important statutory offices such as the chief administrative officer of the county highway department and the important employment position of director of schools, counties have various other offices and employment positions that have been created by either general law or private act.  Some of the offices and positions described are not found in all counties but are fairly common.

An explanation of the office of Judicial Commissioner can be found under Courts. Election Administrators are covered under Elections and County Building Commissioner is covered under Land Use, Planning and Zoning.
