A county commissioner is an elected official who is part of a county commission or board of county commissioners. The commission is responsible for administering the county government in some states of the United States, and usually comprises three to five members. In North Carolina, for example, the board of county commissioners is responsible for adopting the countys annual budget, establishing the annual property tax rate, appointing various officials and representatives to advisory boards and commissions, enacting local ordinances, calling for bond referenda, entering into contracts, establishing new programs and departments, and serving as liaisons to local, state, and federal boards and commissions. County commissioners are responsible for overseeing the countys management and administration, representing county interests at the state and federal level, and serving on advisory boards or commissions that provide direct and indirect county services, such as airports, libraries, community corrections, local public health boards, day care centers, nursing homes, hospitals, and joint solid waste commissions. Commissioners also communicate their home countys concerns to state legislators and federal policymakers, and promote economic development in the county at events for business groups and civic organizations. State law defines the roles and responsibilities of commissioners, including what commissioners can regulate through ordinances and resolutions. Overall, county commissioners are key policymakers who oversee the operation and administration of the county, and are responsible for representing the interests of their communities during regular meetings of the county board and at state and federal events.
