Opening the official parcel viewer
Begin with the Allegheny County ArcGIS parcel map; it covers every assessed parcel from Mount Oliver to Whitehall. For property near Mount Oliver, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Near Whitehall, write down the parcel ID while you have it open; each records desk in the county will want it.
City limits and county records
Brentwood is part of Allegheny County, Pennsylvania, and the county assessor maps its lots. With a lot near Whitehall, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the city limits out by Dormont generally follows county rules rather than the town's.
Taxes on the record
The record for a parcel near Castle Shannon often lists value and tax amounts; questions about value go to the county assessment office.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Castle Shannon are filed with the Recorder of Deeds. For land near Baldwin, have ready the book and page listed on the parcel record so staff can find the deed fast.
Who the record really names
Closer to Whitehall, the owner field shows who the tax bill names, which may be a person, a trust, a company or an estate. "Estate of" on a record near Dormont often points to an open probate, so the personal representative is the contact.
How land is described here
Tracts outside towns near Pleasant Hills commonly use metes-and-bounds descriptions, which trace the boundary call by call. Town lots near Castle Shannon are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Dormont before you request a deed or survey.
Deeds behind the record
Use the book and page or instrument number from the record near Baldwin so the lookup is fast; a title search is wise before any purchase.
Getting answers from the right desk
Questions about value or the owner field for land near Castle Shannon belong with the county assessment office, the office behind the parcel record. Questions about what you can build around Castle Shannon go to planning, building or health offices, town or county, depending on location.
What the map can't tell you
Parcel lines are drawn for taxes, not measured on the ground, so a tree line near Mount Oliver often sits some distance off the line on screen. Closer to Mount Oliver, records update in batches, so a deed recorded last month might lag behind.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Whitehall, but coverage can be spotty out of town. A saved image of the lot near Baldwin and its lines is a good backup.
Looking around the parcel
Click the parcels around the one near Whitehall to see who owns the neighboring land; that's handy for easements and access.
