A Castle Shannon property search: start here
Use the Allegheny County ArcGIS parcel map for a Castle Shannon property search; addresses, names and parcel numbers all work.
Getting to the right map
Begin with the Allegheny County ArcGIS parcel map; it maps every tax parcel in the county, Bethel Park included. If the land is near Green Tree, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near Whitehall, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
City limits and county records
Castle Shannon lies within Allegheny County, Pennsylvania, so its parcels are on the county's map. For a tract near Dormont, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits out by Whitehall usually follows county rules instead.
Land on the county line
Allegheny County borders Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County; every one of them runs a separate parcel map. Ground near Whitehall that runs to the line may be split in two county records, so check the neighboring map as well. Closer to Mount Oliver, our state page links every bordering county map across Pennsylvania.

Where the recorded documents are

Taking the map into the field
