County Government
Functions and Responsibilities

As an agent of the state, the county government serves the entire county in these ways: (1) through elected officials, it administers and enforces state laws, collects taxes, assesses property, records public documents, conducts elections, issues licenses; (2) through appointed boards and officials, it provides parks, libraries, sewers, emergency management, public assistance, and hospitals. As required by state law, county government also serves unincorporated areas by providing such purely local government facilities and services as highways, police protection, building inspection, planning and zoning. Elected county officials oversee most of these services. A city or village may contract with the county to receive a service.

Hamilton County has no top executive and no single overall governing body. Responsibility for county government is shared by the Ohio General Assembly that has legislative power; the county courts that have judicial powers and a three-person board of county commissioners and eight other county officials who have administrative powers. Also participating in Hamilton County government are a number of semi-independent boards and commissions created by the state, or permitted by state law and created by the authorities specified when the need arises.
