Getting oriented in Washington County
Parcel searches in Washington County tend to center on Washington, the county seat, plus Monongahela, Allenport, Beallsville, and Bentleyville. Don't overlook unincorporated places like Aaronsburg, Atlasburg, and Avella, where rural homesites often come up. The county was organized in 1781 and named for George Washington, so some tracts carry a long chain of deeds. The county's land area is about 857 square miles, and the Census Bureau estimated 210,232 residents there in 2023. Much of Washington County is built out, so the parcel map is busiest with subdivision lots, though rural edges and undeveloped tracts still turn up.
Where to find the official Washington County GIS map
The official map is the Washington County ArcGIS parcel map, which runs on an Esri ArcGIS web map. Search an address in Allenport, or pan out toward Baidland and click a rural tract; either way the record pops up with owner and acreage. Our Washington County, PA page keeps the current link if the official address changes.
Reading boundaries on the GIS map
Parcel boundaries on the Washington County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Expect irregular shapes around Burgettstown. Pennsylvania deeds trace boundaries by bearing and distance, often from one old marker to the next. Corner pins, a recorded plat and a Pennsylvania licensed surveyor beat any line on a screen.
Behind the map: land records in Washington County
The map near Allenport is only as good as the deeds behind it, and those are kept in the county's recording office. Check the county government website to see which office records deeds for land near Baidland. When the chain of title matters for land near Allenport, ask for the full deed history or hire a title company in Pennsylvania.
Who needs this map
Different people come to the Washington County parcel map for different reasons.
- For a house near Baidland, the parcel record confirms acreage and shows whether the driveway appears to cross another tract.

Private and public hunting ground in Washington County

A note on timing and acreage
A lot in Beallsville that sold last month may still show the previous owner on the map. Acreage on the Washington County map is a tax figure; a survey is what a lender or buyer should rely on.
