Where the Monroeville GIS map lives
In most places the county maintains the parcel layer, so for this city the go-to is the, at least around Duquesne.Allegheny County ArcGIS parcel map.
Opening the official parcel viewer
Begin with the Allegheny County ArcGIS parcel map; it maps every tax parcel in the county, Wall included. Out toward Wilmerding, 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 Wilmerding, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Monroeville and the county around it
Monroeville sits in Allegheny County, Pennsylvania, which means parcel data comes from the county. For land near Pitcairn, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits toward Wilmerding generally follows county rules, not municipal ones.
Legal descriptions in Pennsylvania
Tracts outside towns near Wilmerding commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in East McKeesport usually use lot and block from a recorded plat instead, making them easier to find. Copy the legal description from the record for the parcel near Pitcairn for any title or survey request.
Troubleshooting the viewer
If the viewer stalls on a phone near Turtle Creek, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Finding the right lot
By address works best for lots in Monroeville; for owner searches, try last name first. Closer to Wilmerding, searching by parcel number never misses, and it's printed on tax bills.
Land on the county line
Allegheny County touches Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County, all with their own assessor records. A tract near the line by Trafford can be split in two county records, so open the neighboring map too. Around East McKeesport, our state page links every bordering county map for Pennsylvania.
Keeping a record
Save a screenshot of the lot near East McKeesport and its record panel, which helps later when you ask the assessor or a title company.
Layers worth turning on
Closer to Pitcairn, look in the layer list for municipal boundaries, floodplain and sometimes zoning; not every viewer has them all.
What the map can't tell you
Acreage on the record is a tax-roll number; only a licensed surveyor can set the real boundary for a parcel near East McKeesport. If you're looking near Wall, records update in batches, so a deed recorded last month might lag behind.
On site with the map
Most viewers work in a phone browser, useful out on a road near Pitcairn, but coverage can be spotty out of town. A saved image of the lot near Wall and its lines is a good backup.
