The official viewer behind the Bethel Park GIS map
Near Whitehall, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Your first stop is the Allegheny County ArcGIS parcel map; it maps each tax parcel from Whitehall to Bridgeville. For acreage around Pleasant Hills, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For property near Castle Shannon, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Where Bethel Park fits in
Bethel Park is part of Allegheny County, Pennsylvania, so its parcels are on the county's map. If you're looking near Bridgeville, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the town limits toward Whitehall generally answers to county rules, not municipal ones.
Who handles what
Questions about value or the owner field for land near Dormont go to the county assessment office, the office behind the parcel record. Building or septic questions for a lot near Bridgeville need the planning or permitting office, town or county, depending on location.
Backing up the map with records
Before you sign anything, pull the recorded deed from the Recorder of Deeds; the parcel map near Bridgeville only summarizes it. Inherited tracts near Brentwood can trace back through a long string of deeds, so a title company earns its fee on a real sale.
Three ways to find a parcel
Addresses are the easiest route inside Bethel Park; owner search often wants the surname first. For acreage around Castle Shannon, searching by parcel number never misses, and you'll find it on tax statements.
When a parcel crosses a boundary
Allegheny County borders Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County, all with their own assessor records. A tract near the line by Castle Shannon can show up across two assessors' files, so check the neighboring map too. For land near Brentwood, our state page lists each bordering county map for Pennsylvania.
Limits of the parcel data
Acreage on the record is an estimate; just a licensed surveyor establishes the real corners for a parcel near Pleasant Hills. In and around Castle Shannon, records update in batches, so a deed recorded last month might lag behind.
Sections, lots and bearings
Older tracts around Brentwood commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Platted lots around Brentwood usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Castle Shannon before you request a deed or survey.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Bridgeville, but coverage can be spotty out of town. A screenshot of the parcel near Dormont with its ID is a good backup.
