Arlington County Virginia Government

Arlington County operates under a council-manager form of government, one of the most structured municipal governance models in Virginia, and serves as the smallest self-governing county by land area in the United States at 26 square miles (Arlington County, Virginia — Official Site). This page covers the structure of Arlington County's government, how its administrative and legislative functions operate, the scenarios in which residents and entities interact with county authority, and the boundaries of that authority relative to state and federal jurisdiction. Understanding how Arlington's government is organized matters because the county exercises broad land use, taxation, and public services authority over a dense urban population that the U.S. Census Bureau counted at approximately 238,000 residents in 2020.

Definition and scope

Arlington County is a legally independent jurisdiction under the Code of Virginia, meaning it is not subordinate to any surrounding county government and does not share administrative authority with an adjacent city in the way that some Virginia counties do. Its governmental authority derives from Title 15.2 of the Code of Virginia, which governs counties, cities, and towns across the Commonwealth.

The governing body is the Arlington County Board, a five-member elected panel that functions as both the legislative and quasi-judicial authority for the county. The Board appoints a County Manager who oversees day-to-day administrative operations, including a staff of roughly 3,600 full-time employees across departments spanning public safety, planning, transportation, human services, and parks. This council-manager structure separates policy-making (the Board's role) from administration (the County Manager's role), a distinction that defines how decisions flow from elected officials to service delivery.

Scope of coverage this page addresses:

  1. Arlington County's internal governance structure and how the County Board, County Manager, and department-level agencies interact
  2. The specific scenarios — zoning approvals, budget adoption, school governance coordination — in which county authority is most directly exercised
  3. The decision boundaries between Arlington County government and the Virginia state government, the federal government (given Arlington's proximity to Washington, D.C.), and neighboring jurisdictions

What falls outside this page's scope: Arlington County's government operates exclusively within the 26-square-mile jurisdiction of Arlington, Virginia. This page does not cover the government of Fairfax County to the west, the City of Alexandria to the south, or any federal agencies headquartered in Arlington — including the Department of Defense facilities at the Pentagon. Federal properties within Arlington's boundaries are not subject to county zoning or taxing authority. Readers looking for a broader survey of Virginia county governance can consult the Virginia Counties Overview page.

How it works

Arlington County's governmental machinery operates through three primary channels: the County Board, the County Manager's office, and a network of advisory commissions.

The County Board holds 5 elected at-large seats, with members serving staggered four-year terms. The Board adopts the annual budget, sets the real property tax rate, enacts zoning ordinances, approves use permits, and represents the county before the Virginia General Assembly. Because Arlington has no separate city council or mayor, the County Board concentrates legislative power that other Virginia localities divide across multiple bodies.

The County Manager reports directly to the Board and implements Board-adopted policy. The Manager's office coordinates 7 major service clusters:

  1. Management and Finance — budget preparation, procurement, and revenue administration
  2. Human Services — social services, mental health programs, and public health coordination
  3. Environment, Development, and Recreation — planning, zoning enforcement, and parks
  4. Facilities and Capital Programs — public infrastructure and capital improvement projects
  5. Information Technology — enterprise systems and cybersecurity policy
  6. Police and Fire — public safety dispatch, law enforcement, and emergency response
  7. Libraries and Cultural Affairs — branch library system and public arts programs

Advisory Commissions — including the Planning Commission, the Transportation Commission, and the Urban Forestry Commission — provide structured public input before the County Board votes on significant matters. These bodies hold no independent legal authority but generate formal recommendations that enter the public record.

Arlington County's fiscal year runs July 1 through June 30 (Arlington County FY Budget Documents). The Board must adopt a balanced budget by April 30 each year under Virginia law, and the county's real property tax rate — historically among the higher rates in Northern Virginia — is set at that time.

Common scenarios

The most frequent points of contact between residents, businesses, and Arlington County government include:

Zoning and Land Use Approvals. Arlington's General Land Use Plan designates corridors such as the Rosslyn-Ballston Corridor and the Richmond Highway corridor for mixed-use density. Developers seeking use permits, special exceptions, or site plan approvals must proceed through the Zoning Administration Division, receive a Planning Commission recommendation, and obtain County Board approval at a public hearing. This three-stage review is required for any project that departs from by-right zoning.

Property Tax Assessment. The Arlington County Department of Real Estate Assessments values all taxable real property annually. Property owners who dispute an assessment may appeal first to the Board of Equalization, then to the Arlington Circuit Court under Code of Virginia §58.1-3980.

School Governance Coordination. Arlington Public Schools operates under an independently elected School Board, separate from the County Board. However, the County Board controls the school system's budget allocation — a structural tension that recurs annually during budget season. The School Board adopts its requested budget; the County Board sets the actual transfer amount.

Human Services Applications. County residents seeking benefits under state-administered programs — including Medicaid, Supplemental Nutrition Assistance Program (SNAP), and Temporary Assistance for Needy Families (TANF) — apply through the Arlington County Department of Human Services, which administers federal and state funds locally under agreements with the Virginia Department of Social Services.

Decision boundaries

Arlington County government operates within a layered authority structure that constrains its discretion at both the upper and lower ends.

State preemption. The Virginia General Assembly can preempt any county ordinance on matters it reserves for state-level regulation — including firearms, telecommunications infrastructure placement, and certain environmental standards. Arlington County has no home rule charter in the traditional sense; its powers are defined by Dillon's Rule, under which localities may only exercise authority expressly granted by the state (Code of Virginia §15.2-1200). This distinguishes Virginia counties from those in home-rule states.

Federal jurisdiction. Approximately 28 percent of Arlington's land is held by the federal government or under federal jurisdiction, encompassing Ronald Reagan Washington National Airport (operated by the Metropolitan Washington Airports Authority under federal charter), Arlington National Cemetery (administered by the Department of the Army), and the Pentagon reservation. These properties pay no county property tax and are governed by federal, not county, rules.

Contrast: Arlington vs. Fairfax County. Both Arlington and Fairfax County operate under Virginia's council-manager model, but Fairfax — at 407 square miles with a population exceeding 1.1 million — maintains a Board of Supervisors with 9 district-elected members plus a chairman elected at-large, compared to Arlington's 5 at-large members. Fairfax also supports a larger independent Economic Development Authority with separate bonding capacity. Arlington's smaller geographic footprint means zoning decisions carry proportionally higher density implications per square mile than those in Fairfax.

Boundaries with neighboring jurisdictions. Arlington County does not extend municipal services beyond its borders. The City of Alexandria, which borders Arlington to the south, is a fully independent city under Virginia law and manages its own separate government.
