For a parcel in or near Whitehall, the Whitehall GIS map lays out lines, owner names and parcel numbers. Covered here for Whitehall: where that map lives, how to search it, and what to double-check with records.
Getting started with the Whitehall GIS map
In and around Bethel Park, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The free map to start with
The public parcel map for this area is the Allegheny County ArcGIS parcel map, and no login is needed to use it. Around Dormont, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward Castle Shannon, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
A word on accuracy
The acreage figure is an assessed number; just a licensed surveyor establishes the real boundary for a parcel near Bethel Park. With a lot near Dormont, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Troubleshooting the viewer
If the viewer stalls on a phone near Brentwood, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Whitehall, PA: the basics
Whitehall lies within Allegheny County, Pennsylvania, which means parcel data comes from the county. If the land is near Pleasant Hills, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits out by Dormont generally falls under county rules, not municipal ones.
On site with the map
Most viewers work in a phone browser, useful out on a road near Bethel Park, so load it before you lose signal. A printout of the tract near Pleasant Hills helps when you meet an owner or agent.
Legal descriptions in Pennsylvania
Tracts outside towns near Pleasant Hills are often described by metes and bounds, a series of courses and distances from a starting point. Subdivision lots in Castle Shannon are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Dormont when you talk to a surveyor.
A quick look at the area

About 1,224,825 people live in Allegheny County (Census Bureau estimate, 2023) across roughly 730 square miles. Allegheny County was formed in 1788, and some chains of title near Pleasant Hills are long. Features like Allegheny River and Monongahela River make handy reference points on the map near Castle Shannon.
Finding the right lot

Backing up the map with records
