Loudoun County, Virginia is divided into eight magisterial districts: Algonkian, Ashburn, Broad Run, Catoctin, Dulles, Leesburg, Little River, and Sterling. The magisterial districts each elect one supervisor to the board of supervisors which governs Loudoun County. There is also a chair elected by the county at-large, bringing total board membership to nine. Board members serve concurrent, four-year terms. A vice chair is selected by the board from among its membership. The current chair is Phyllis Randall and the current vice chair is Mike Turner, the Ashburn District Supervisor. He has served as vice chair since January 2025. Salaries for the board term of 2024–2027 were set by the previous board in January 2023.

Meeting schedule The board of supervisors' meeting schedule is set forth in its Rules of Order. Business meetings typically occur twice monthly, beginning on the first Tuesday of the month at 5:00 p.m. The board holds one public hearing monthly, currently at 6:00 p.m. on the Wednesday that follows the first business meeting. The second business meeting occurs at 5:00 p.m. on the next Tuesday following the public hearing. The board's standing committees also usually meet monthly. The meetings are held at the Loudoun County Government Center, 1 Harrison Street, S.E. in Leesburg. The board's official meeting schedule is published in accordance with § 2.2-3707 of the Virginia Freedom of Information Act (FOIA) on the master calendarmaster calendar on the county's website.

Actions As empowered by the Code of Virginia, the board of supervisors typically takes action within its purview during each of its business meetings, public hearings, and standing committee meetings. The board has both administrative and legislative responsibilities, some of which are discharged in the role of the local governing body and some of which have derived from its function as an administrative subdivision of the state. The powers and duties of the board of supervisors include:

Adopting the county budget (establishing appropriations and setting the tax rates); Approving and enforcing the county's comprehensive land use plan and related ordinances; Making and enforcing ordinances for public safety, sanitation, health and other regulations permitted by state laws; and Providing for the care and treatment of indigent and handicapped citizens.

Over time, a board of supervisors may take thousands of individual actions in open session by motion and majority vote during its meetings. The official actions of the Loudoun County Board of Supervisors are documented on the county's website, in the form of a copy teste, a "true copy" of the county's official record of Board actions, produced, signed, and published by the clerk on the county's website.
