Buying Land in Lancaster County, Virginia

A Northern Neck county with a genuine agricultural and shoreland zoning framework

Lancaster County sits at the tip of Virginia's Northern Neck along the Rappahannock River and the Chesapeake Bay, with the town of Kilmarnock as its commercial center. While the county is well known for its waterfront and retirement-oriented real estate market near Kilmarnock and Irvington, this page focuses on the inland zoning and land-use mechanics that govern rural acreage countywide -- the A-1 and A-2 agricultural districts set out in the county's Land Development Code.

A-1 and A-2: two agricultural districts with different purposes and lot sizes

Lancaster County's zoning ordinance establishes two separate agricultural districts. The A-1, or Agricultural, Limited district, carries a 2-acre minimum lot size and is specifically described in the ordinance as covering land occupied by open uses -- forests, parks, farms, lakes, marshlands, and wetlands -- established to provide for safe and orderly shoreland development, facilitate existing and future farming operations, conserve water and other natural resources, reduce soil erosion, protect watersheds, and reduce flood and fire hazards. That's a notably conservation-oriented purpose statement for an agricultural district, and it comes with a specific structural limit: only one principal building and its accessory buildings may be erected on any single A-1 lot or parcel, regardless of that lot's total acreage.

The A-2 district, by contrast, carries a much smaller 33,000-square-foot (roughly 0.75-acre) minimum lot size -- a meaningfully different density allowance from A-1, and one that matters directly if you're comparing two similarly priced parcels zoned differently. Some uses and developments across Lancaster's agricultural districts require a "special exception" granted by the Board of Supervisors rather than being allowed by right, typically because the nature of the use calls for more intensive public scrutiny and discussion -- confirm whether your specific plan (an event venue, an intensive agricultural operation, a non-farm business) needs this extra step before assuming it's automatically permitted.

Septic and well: Three Rivers Health District

Septic and well permitting for Lancaster County runs through the Virginia Department of Health's Three Rivers Health District rather than a county department, consistent with Virginia's statewide model. Given the A-1 district's own stated focus on shoreland and watershed protection, soil and site conditions near the county's extensive tidal shoreline are a genuine, specific feasibility question -- confirm directly with the health district whether a shoreline-adjacent A-1 parcel can support a conventional septic system, since setback requirements from tidal waters and wetlands can further limit buildable area beyond the base 2-acre A-1 minimum.

For any Lancaster County parcel, the county's Planning Office is the right first call to confirm zoning district, minimum lot size, and whether a special exception applies to your plan, and the Three Rivers Health District the right second call to confirm septic and well feasibility before you commit to a purchase.
