What this office does

County commissioner. The county board is the county's legislative and, in most states, executive body. Commissioners adopt the county budget and property tax rate, oversee roads, the jail, public health, planning and zoning in unincorporated areas, and appoint or confirm department heads. In counties with an elected county executive or judge, the board's role is mainly the budget and ordinances.
