Buying Land in Northumberland County, Virginia

A rural Northern Neck county between two waterways

Northumberland County sits at the eastern tip of Virginia's Northern Neck peninsula, bordered by the Potomac River to the north and the Chesapeake Bay to the east, seated in the small town of Heathsville. With a 2020 Census population of 11,839 across roughly 191 square miles of land (a large share of the county's total area is water), Northumberland carries a genuinely rural, low-density character. This page focuses on the inland zoning and land-use mechanics relevant to a rural land purchase rather than waterfront real estate, which a sibling site may cover in more depth.

Zoning: agriculture and forestry by right in the A-1 district

Northumberland County has adopted a zoning ordinance that includes an Agricultural District (A-1), covering land used for farms, orchards, vineyards, forests, and parks, and intended to facilitate existing and future farming and forestry, conserve natural resources, and reduce erosion, flood, and fire hazards. Under Virginia's statewide Zoning Enabling Act, a locality's zoning ordinance is not allowed to require a special exception or special use permit for a production agriculture or silviculture activity in a district zoned agricultural -- so a genuine farming or forestry operation in Northumberland's A-1 district does not need special-permit approval to proceed.

That by-right protection covers farming and forestry specifically, not every use a buyer might picture on agriculturally zoned land. The county's ordinance also addresses cluster-development standards and other district-specific rules, so a buyer planning anything beyond production agriculture -- a home-based business, an event venue, additional dwellings on the parcel -- should confirm the current allowed-use list and any special-permit requirements directly with the county's Zoning Office before assuming an agricultural designation covers it automatically.

Septic, well, and water rights follow the statewide Virginia model

As in every Virginia locality, septic and private well permitting for a Northumberland County parcel is a state function, not a county one. The Northumberland County Health Department -- part of VDH's Three Rivers Health District -- reviews the site, approves the system design, and issues the construction permit for a typical single-family system. Given the county's high proportion of tidal wetlands and water, soil and site conditions for septic feasibility can vary significantly parcel to parcel, so confirm perc-test and site-evaluation results directly with the health department rather than assuming a neighboring lot's history applies.

Northumberland is a riparian-rights state county like the rest of Virginia: any surface-water withdrawal averaging more than 10,000 gallons per day in a month generally requires a DEQ Virginia Water Protection Permit, a threshold worth knowing if your land plan involves irrigation or aquaculture drawing from a creek or pond. And because zoning here, as everywhere in Virginia, was drafted independently by the county under a permissive state enabling act, do not assume a district name or use list matches a neighboring county's ordinance -- always confirm directly with Northumberland's own Zoning Office.
