Buying a lot in a subdivision near Dravosburg? What you want is the McKeesport plat map, since it shows lots, streets and easements as approved. What this McKeesport guide covers: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
The McKeesport plat map: start here
For a lot in McKeesport, the deed usually cites the plat; use it to request a copy.
Opening the official parcel viewer
Go first to the Allegheny County ArcGIS parcel map; it includes every assessed parcel from Port Vue to Duquesne. For a home near Glassport, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Duquesne, a pop-up or side panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Which office to call
For assessment questions about property around Duquesne belong with the county assessment office, which maintains the tax roll. Questions about what you can build around Port Vue are for the local planning and health departments, depending on whether the land is inside town limits.
Where McKeesport fits in
McKeesport sits in Allegheny County, Pennsylvania, so its parcels are on the county's map. Closer to Versailles, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the town limits out by Duquesne usually answers to county rules instead.
Allegheny County in a few facts
Pittsburgh serves as the county seat, where most land records are kept. You'll also find Port Vue, Versailles, Duquesne, and Glassport, each with its own cluster of lots. About 1,224,825 people live in Allegheny County (Census Bureau estimate, 2023) on some 730 square miles. Allegheny County was organized in 1788, and some chains of title near Versailles are long. Features like Allegheny River and Monongahela River are easy to spot when you zoom out from White Oak.
Recorded documents worth pulling
Before you sign anything, get the recorded deed through the Recorder of Deeds; the parcel map near Versailles only summarizes it. Long-held tracts near White Oak can trace back through many deeds, so a title company is worth hiring before a purchase.
When a plat changes
Lots near Port Vue can be combined or reconfigured by a replat, so check for later filings; street vacations show up in the records too.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor can set the real boundary for a parcel near Versailles. If the land is near Port Vue, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Two different maps
The tax map on the Allegheny County ArcGIS parcel map is a summary, whereas the plat carries surveyed dimensions.
Reading the legal description
Tracts outside towns near Port Vue commonly use metes-and-bounds descriptions, which trace the boundary call by call. Subdivision lots in Port Vue are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Port Vue before you request a deed or survey.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Versailles, so load it before you lose signal. A printout of the tract near Glassport helps when you meet an owner or agent.
Lots, blocks and easements
For acreage around Versailles, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Requesting the plat
Closer to Duquesne, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
When there's no plat
Acreage around Port Vue outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Dravosburg.
