Buying Land in Mathews County, Virginia

A small, low-lying Middle Peninsula county

Mathews County sits on Virginia's Middle Peninsula, nearly surrounded by the Chesapeake Bay and its tributary creeks and rivers, with the small town of Mathews serving as county seat. It's a genuinely rural, low-density county with a working agricultural and maritime history, but its defining physical feature is elevation: Mathews is flat and low-lying across nearly its entire land area, not just along its immediate coastline. This page focuses on the county's inland zoning and agricultural land-use rules rather than waterfront real estate, which a sibling site covers separately -- but the low elevation itself is relevant to any buyer, coastal-facing parcel or not.

Zoning: the Rural District and its 2.5-acre minimum

Mathews County's zoning ordinance (Chapter 175 of the county code) includes a Rural District (RU) that governs much of the county's land outside its residential districts (R-1 and R-2) and the town of Mathews. Under Article 5 of that ordinance, the minimum lot area for each principal permitted use in the RU district is 2.5 acres. There is a specific, narrow exception: a parent parcel that was already a legally recorded lot before July 22, 1997 may be subdivided into a maximum of one lot smaller than 2.5 acres, provided that smaller lot is not less than 1 acre. Parcels recorded on or after that date do not get this allowance and must meet the full 2.5-acre minimum for any new lot.

That July 1997 cutoff date matters in practice: if you're evaluating a smaller, sub-2.5-acre lot in the RU district, ask the county's Planning Commission when the parent parcel was recorded and whether this specific exception was actually used, rather than assuming a small lot is automatically buildable. The county also maintains separate R-1 and R-2 residential districts with their own area regulations, distinct from the rural district's rules.

Flood zones, septic, and the practical cost of low elevation

Because Mathews County sits so low relative to the Chesapeake Bay, FEMA flood-zone designations reach further inland here than in a typical hillier Virginia county. A parcel that looks purely rural and inland on a map can still carry meaningful flood-zone status, which affects insurance costs, foundation requirements, and -- relevant to septic siting -- how a drainfield performs in a high water table. Confirm flood-zone status through FEMA's map service and the county's floodplain administrator for any specific parcel before assuming build costs will be standard.

Septic and private well permitting in Mathews County runs through the Three Rivers Health District, a Virginia Department of Health office covering a 10-county stretch of the Northern Neck and Middle Peninsula, with the Mathews County Health Department located at 536 Church Street in the town of Mathews. Given the county's high water table and low elevation, a site evaluation from that health district is especially important here -- a conventional septic system that would work easily in a higher, better-drained county may need an alternative design in parts of Mathews.
