If a legal description for land in Jefferson Hills cites a lot number, you'll need the Jefferson Hills plat map to make sense of it. What this Jefferson Hills guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Who keeps the Jefferson Hills plat map
For a lot in Jefferson Hills, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
Pulling up a parcel
Go first to the Allegheny County ArcGIS parcel map; it includes each tax parcel around West Elizabeth and Pleasant Hills. When a rural tract has no street number, zoom in from Clairton until the lines appear, then click inside the one you want. In and around Lincoln, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near West Elizabeth, so load it before you lose signal. A printout of the tract near West Elizabeth is a good backup.
Where Jefferson Hills fits in
Jefferson Hills sits in Allegheny County, Pennsylvania, which means parcel data comes from the county. In and around Clairton, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the town limits near Elizabeth often answers to county rules instead.
When there's no plat
Rural land near West Elizabeth that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Lincoln.
Reading the legal description
Older tracts around Clairton commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Platted lots around Glassport refer to a recorded plat, which is simpler to follow. Copy the legal description from the record for the parcel near Elizabeth when you talk to a surveyor.
Which office to call
For assessment questions about property around Clairton belong with the county assessment office, since that office keeps the assessment data. Zoning, permits and septic questions near West Elizabeth go to planning, building or health offices, depending on whether the land is inside town limits.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements covering ground around Pleasant Hills are kept by the Recorder of Deeds. Inherited tracts around Clairton may go back through a long string of deeds, so a title company can sort it out if money is changing hands.
Two different maps
The tax map on the Allegheny County ArcGIS parcel map is a summary, but the recorded plat is what the deed relies on.
Amended plats
Lots near West Elizabeth can be combined or reconfigured by a replat, so check for later filings; street vacations near Clairton show up in the records too.
