Buying Land in King George County, Virginia

A rural Potomac/Rappahannock county -- not to be confused with its similarly named neighbors

King George County sits between the Potomac and Rappahannock Rivers in the Fredericksburg region of Virginia's Northern Neck, home to Dahlgren Naval Surface Warfare Center along its Potomac shoreline but rural and agricultural through most of its interior. It shares a naming pattern -- and nothing else -- with King William County and King and Queen County, two entirely separate Virginia jurisdictions with their own governments, ordinances, and land records; if you're researching any of the three, double-check which specific county's documents you're actually reading before relying on a figure.

One Dahlgren-related item worth knowing about, even though it isn't current law: the county, NSF Dahlgren, and a planning consultant drafted a Military Compatibility Area Overlay District (MCAOD) through a Joint Land Use Study, intended to address noise and lighting near the base for nearby land uses. As of the most recent information found in this research pass, the county had put drafting of that overlay on pause following a June 2022 review, and no source located confirms it has since been adopted. If you're evaluating a parcel near Dahlgren, ask the county directly whether the MCAOD (or any successor overlay) has since moved forward, rather than assuming either the paused draft or the absence of any overlay currently governs the property.

The county's Board of Supervisors has an active Zoning & Subdivision Ordinance Update process underway, so a specific district's rules are worth double-checking for recent amendments rather than assumed static from an older printed copy of the code.

Three agricultural districts, three different intents

Unlike many rural Virginia counties that maintain a single general agricultural district, King George County splits its rural land into three separate tiers: A-1 Agriculture Preservation, A-2 Rural Agriculture, and A-3 General Agriculture. That structure suggests a deliberate effort to differentiate land meant primarily for active farming preservation from land meant for a mix of rural residential and low-impact non-residential use -- a distinction worth understanding before assuming any one agricultural zoning label covers your intended use.

The A-2 Rural Agriculture district is explicitly described in the county's own ordinance as intended to recognize the rural character of portions of the county while allowing increased residential and low-impact non-residential uses that complement rural living and provide basic services to the surrounding community, provided those non-residential uses aren't disruptive to existing farming and rural living patterns. Residential uses in A-2 are meant to consist of single-family dwellings on parcels large enough to provide for a private well and septic system -- meaning lot sizing in this district is tied directly to onsite water and wastewater feasibility rather than a flat acreage minimum alone. This page did not independently confirm the specific minimum lot sizes for A-1, A-2, or A-3, so confirm those figures, along with each district's current by-right and special-permit use lists, directly with the county's Planning & Zoning office.

Septic and well: Rappahannock Area Health District

Septic and well permitting for King George County parcels runs through the Virginia Department of Health's Rappahannock Area Health District, reachable at 540-899-4797, rather than a county department -- consistent with Virginia's statewide model. Given the A-2 district's explicit tie between lot size and private well/septic capacity, a site-specific soil and well-siting evaluation is especially worth getting early in your due diligence if you're evaluating a King George parcel for a new home site, since it will directly inform how the county's own zoning logic treats that lot.

Water rights on any King George parcel follow Virginia's statewide riparian doctrine, with the same DEQ Virginia Water Protection Permit threshold applying to a nontidal surface withdrawal over roughly 10,000 gallons per day averaged monthly -- worth checking if your plan for a river- or creek-adjacent King George parcel involves meaningful irrigation or livestock-watering draw.
