Before you buy a lot near Pitcairn with a plan in mind, pull up the Monroeville zoning map first: a district label decides setbacks, lot size and uses. In this Monroeville guide: which office sets the rules for a lot, matching a lot to its zoning district, and what to ask the planning staff.
The Monroeville zoning map: start here
Inside town or city limits, zoning usually comes from the municipality, which means a parcel in Monroeville is governed there. Outside those limits, near Pitcairn or Trafford, the county's ordinance, if any, takes over; ask the county planning office to be sure. To find out which side of the line a parcel is on: look for a city limits layer in the Allegheny County ArcGIS parcel map.
The viewer Allegheny County publishes
Go first to the Allegheny County ArcGIS parcel map; it covers every tax parcel in the county, Wilmerding included. If you only know roughly where the land is, pan along Interstate 376 and select the outline. If the land is near Wilmerding, write down the parcel ID before closing the panel; every office in the county asks for it first.
Permits after zoning
Even when zoning allows a use near Pitcairn, a building permit is a separate step; health and road departments may weigh in on land near Trafford.
Neighboring parcel maps
Allegheny County borders Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County, and each of those keeps its own parcel map. A tract near the line by Wilmerding may show up across two assessors' files, so open the adjacent map as well. Around Wall, our state page links every bordering county map for Pennsylvania.

Monroeville, PA: the basics
Monroeville is part of Allegheny County, Pennsylvania, which means parcel data comes from the county. Near Trafford, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the town limits out by Wilmerding generally falls under county rules instead.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Wilmerding are kept by the Recorder of Deeds. Inherited tracts around Wall may go back through several deeds, and a title company can sort it out if money is changing hands.
Reading the legal description
Tracts outside towns near Trafford commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Platted lots around Pitcairn usually use lot and block from a recorded plat instead, making them easier to find. Keep the legal description for land near Wall before you request a deed or survey.
Finding a parcel's zoning district
Pull the parcel up on the Allegheny County ArcGIS parcel map, note the parcel number, and use it when you ask the planning office near Pitcairn. For land near Turtle Creek, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; the letters vary from place to place.
Calling planning staff
When you call about land near Wilmerding, give the parcel number and your intended use; staff can point to the right section of the ordinance. Also ask whether the lot near East McKeesport is a legal lot of record, since some older splits don't.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near East McKeesport, but coverage can be spotty out of town. A screenshot of the parcel near East McKeesport with its ID helps when you meet an owner or agent.
Reading the ordinance
For property near Wall, the ordinance spells out what's allowed outright and what needs approval. For land near Wall, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
Changing what's allowed
On ground around Trafford, expect an application, a fee, notice to neighbors and a public hearing.
