Before you buy a lot near Brentwood with a plan in mind, look at the Bethel Park zoning map first: a district label decides setbacks, lot size and uses. In this Bethel Park guide: who controls zoning for a given parcel, matching a lot to its zoning district, and the questions that save a wasted trip.
Reading the Bethel Park zoning map for one lot
Within municipal limits, zoning usually comes from the municipality, so property inside Bethel Park answers to that map. Outside those limits, near Bridgeville or Pleasant Hills, the county may have its own zoning, or none at all; confirm with the county office. To find out which side of the line a parcel is on: ask whether the parcel near Dormont is inside the boundary.
Getting to the right map
Begin with the Allegheny County ArcGIS parcel map; it includes each tax parcel in the county, Dormont included. When a rural tract has no street number, follow Interstate 376 on the aerial until the lines appear, then click inside the one you want. For a tract near Pleasant Hills, write down the parcel ID before closing the panel; every clerk in the county uses it to find the file.
Next door to Allegheny County
Allegheny County meets Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County; every one of them runs a separate parcel map. A tract near the line by Dormont can show up across two assessors' files, so look at the neighboring map as well. On ground around Whitehall, our state page links each neighboring county map for Pennsylvania.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Whitehall are kept by the Recorder of Deeds. Out toward Brentwood, have ready the book and page from the tax record and the lookup takes minutes.
Building permits and inspections
Even when zoning allows a use near Castle Shannon, a building permit is a separate step; septic or sewer and driveway access are often reviewed too.
