The office of the County Auditor was created in 1870 as part of a revamping of county government.
The duties of the office covered areas that had previously been given to the County Judge in 1851, in the first Code of Iowa, and then to the Clerk of Court in 1861, with the formation of the Board of
Supervisors. The State Legislature added the duties of Commissioner of Elections in the early 1970s. The County Auditor is an elected position, with a term of four years.
