Counties in Ohio do not possess home rule powers but can do only what has been expressly authorized by the Ohio General Assembly. Like eighty-six other counties (the exception is Summit), the county has the following elected officials, as provided by statute:

  • Three county commissioners (the Board of Commissioners): Control budget; approve zoning; approve annexations to cities and villages; set overall policy; oversee departments under their control
  • County auditor: Values property for taxation; issues dog, kennel, and cigarettelicenses; issues licenses for retailers for sales tax purposes; inspects scales, pumps, etc., used in commerce to see that they are accurate
  • County clerk of court of common pleas: Keeps filings of lawsuitsand orders of the county court of common pleas; records titles for motor vehicles
  • County coroner: Determines causes of deathin certain cases; is the only person with the power to arrest the sheriff.
  • County engineer: Maintains county roadsand land maps
  • Prosecuting attorney: Prosecutes feloniesand is the legal advisor to all other county officials and departments
  • County recorder: Keeps all landrecords, including deeds, surveys, mortgages, easements, and liens
  • County treasurer: Collects taxes, invests county money, provide financial oversight to municipalities and school districts in the county
  • County sheriff: Chief law enforcement officer, polices areas without local police; runs the county jail; acts as officer of the local courts (transporting prisoners, serving subpoenas, acting as bailiff, etc.)

All of these officials are elected to four-year terms in November of even-numbered years after being nominated in partisan primary elections. One commissioner and the auditor are elected in the same year as the governor in one cycle; the other two commissioners and the other officials are elected in the same year as the president of the United States. The clerk, coroner, prosecutor, recorder, and sheriff begin their terms on the first Monday in January. The auditor’s term begins on the second Monday in March. The treasurer’s term begins on the first monday in September. The commissioner who is elected with the governor begins his term on January 1. Of the other two seats, one term begins on January 2 and the second on January 3.

Any citizen of Ohio and the United States who is eighteen years of age or older and lives in the county may run for commissioner, auditor, treasurer, clerk of courts, or recorder. The other offices have specific additional requirements: candidates for prosecutor must be licensed to practice law; candidates for coroner must be licensed to practice medicine for two years; candidates for engineer must be both licensed surveyors and engineers; and candidates for sheriff must have certain education and supervisory experience in law enforcement.

If a vacancy arises, it is filled by the county central committee of the political party to which the former official belonged, i.e., the Republicans appoint someone to an office held by a Republican and the Democrats to an office held by a Democrat. If an office becomes vacant before the November election in the even-numbered year midway through the term, the appointee must run in a special election for the remainder of the term. If the office becomes vacant after then, the appointment is for the remainder of the term.

The Board of County Commissioners is the combined executive and legislative branch of county government but as their control over the independently elected officials is limited, there is effectively no real executive. However, one of the members of the board is named president of the board. The commissioners receive a full-time salary, but commissioners often have full-time occupations on the side. The board also employs a clerk to record its proceedings.

The board of commissioners often create numerous subordinate departments to handle specific services. These vary from county to county; among the most common are departments for building and zoning, health, economic development, water and sewer service, and emergency management.

There is also a county educational service center (previously known as the county board of education) presided over by a board of education, typically numbering five members, elected to staggered four-year terms in non-partisan elections in odd-numbered years. The center supplies services to the individual school districts in the county and exercises some limited control over the class of school districts known as “local school districts.” (“City school districts” and “exempted village school districts” are free from any oversight by the county board.) Counties also have a board of mental retardation and developmental disabilities to educate disabled children. The members of this board are appointed.

Elections are administered in each county by a four-member board of elections which consists of two Republicans and two Democrats appointed by the Ohio Secretary of State at the recommendation of each county party. The board employs a director, who must be of the opposing political party of the chairman of the board of elections, and a deputy director, who must be of the political party of the chairman of the board.

The county has a court of common pleas, which is the court of first instance for felonies and certain high-value civil cases. All judges in Ohio are elected to six-year terms in non-partisan elections after being nominated in partisan primaries.
