Land questions in Lehigh County start in the same place: the official parcel map. Here's how to use the Lehigh County GIS map to find owners, acreage and boundary lines, and where it falls short.
Who uses the Lehigh County parcel map
- Contractors quoting work near Breinigsville check frontage and lot depth on the map before they drive out.
- Before an offer, buyers in Lehigh County pull the parcel to confirm the lot dimensions and look for anything odd, like a flag lot or a shared drive.
- Raw-land buyers scan Lehigh County imagery for empty tracts and check the owner records behind them.
Where to open the official Lehigh County GIS map
Lehigh County's public parcel map is the Lehigh County ArcGIS parcel map, hosted on an Esri ArcGIS web map. A parcel number from a Lehigh County tax bill is the most precise search; failing that, an owner name or a click on the map near Coopersburg works. We keep the link current on our Lehigh County (PA) directory page, next to the neighboring maps.
Towns, terrain and land across Lehigh County
Allentown is the county seat, and other towns on the map include Bethlehem, Alburtis, Catasauqua, and Coopersburg. Unincorporated spots like Ancient Oaks, Breinigsville, and Cementon are worth a look if you want rural acreage near a crossroads community. Census Bureau estimates show 377,754 residents in 2023 and around 345 square miles of land in the county. Much of Lehigh County is built out, so the parcel map is busiest with subdivision lots, though rural edges and undeveloped tracts still turn up. Terrain such as the Appalachian Mountains and Lehigh Valley IronPigs explains why some parcels are long and narrow while others follow ridgelines.
What the Lehigh County GIS map shows about lot lines
Lines on the map show roughly where one parcel near Allentown ends and the next begins; the exact spot is a surveyor's call. Pennsylvania is a metes-and-bounds state. Rural deeds in Lehigh County describe boundaries with bearings, distances and landmarks rather than a square grid, so parcel lines are often irregular. For a fence, an addition or a dispute in Lehigh County, budget for a licensed survey; it's the answer a court or a lender will accept.
Acreage and vacant lot search
How to work the Lehigh County GIS map for open land:
- With imagery on, zoom to the edge of Allentown where subdivisions give way to open ground.
- For each tract near Emmaus, note the parcel ID, the owner and where the tax bill is mailed.
- Check that the tract touches a public road; a landlocked lot near Allentown can be hard to finance and build on.
- Compare the record's land value against similar parcels on the same road out of Allentown.
- For a tract near Emmaus, confirm zoning, septic suitability and flood status before you make an offer.
For a tract near Emmaus with no road frontage, see how to tell if land is landlocked.
Work and land use in Lehigh County
In the 2022 County Business Patterns data, Lehigh County had 8,627 establishments; retail trade, health care and social assistance, and other services led the count. The local economy leans harder than average on apparel manufacturing, textile mills, and warehousing and storage. Where a tract near Allentown has highway or rail access, expect commercial and farm buyers to take an interest.
Where Lehigh County deeds and plats are kept
Every line on the Lehigh County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Recording offices go by different titles from state to state, including register of deeds, recorder, county clerk and clerk of court; the official Lehigh County website names the one that handles deeds. When the chain of title matters for land near Coopersburg, ask for the full deed history or hire a title company in Pennsylvania.
Neighboring counties
