Virginia–West Virginia Border Counties and Their Parcel Maps
All 27 counties on the Virginia–West Virginia line, with seats, populations and each official parcel map, plus what changes at the line.
Looking for the counties on the Virginia–West Virginia border and their parcel maps? According to the Census Bureau's county adjacency file, 14 Virginia counties touch 13 West Virginia counties along the line. Each one keeps its own property records and its own parcel viewer, so land near the line often means checking two counties in two states.
Below you will find every county on both sides of the line, who borders whom, and what changes when you cross from one records office to the other.

What changes when you cross the line
- Different viewers. On the Virginia side the official maps run on: WebGIS.net (5); InteractiveGIS (4); ArcGIS Web AppBuilder (2); county web map (2); ArcGIS Experience Builder (1). On the West Virginia side: West Virginia Property Viewer (8); ArcGIS Web AppBuilder (3); ArcGIS Experience Builder (2). Search boxes, parcel ID formats and the details shown in pop-ups will differ.
- Different records offices. Deeds, plats and tax bills are kept by the county where the parcel sits.
- Different rules. Zoning, septic permits and property tax are set locally and by each state, so check with the county on the side where you plan to build or buy.
Researching a tract that crosses the line
- Find the parcel in both counties' viewers. Each side will show only its own piece, with its own parcel number.
- Pull the recorded deed from each county's register or recorder, since each county records only the land inside its own boundary.
- Expect two tax bills, one from each county, and check each state's rules for homestead or farm exemptions.
- For a sale, a fence or a building permit, hire a licensed surveyor familiar with the line; tax-map lines are drawings, not surveys.
A quick way to check which side a spot is on
Tap the spot on the Platbookmapper Land Map. Its land report names the county and links straight to that county's parcel viewer, plus FEMA flood, USGS elevation, USDA soil and wetland results.
