Loudoun County is governed by a nine-member Board of Supervisors. The chairman of the Board of Supervisors is elected by the voters at large. The other supervisors are elected from each of eight election districts in the county. All nine members serve concurrent terms of four years.
The Board of Supervisors sets county policies, adopts ordinances, appropriates funds, approves land rezoning and special exceptions to the zoning ordinance, and carries out other responsibilities set forth by the State Code.
The Board appoints a county administrator, who manages county operations; the Planning Commission, which serves in an advisory capacity on land use issues; and various other boards and commissions.
The county administrator is similar in nature to the superintendent of schools.
