If a legal description for land in Munhall cites a lot number, you'll need the Munhall plat map to make sense of it. What this Munhall guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Tracking down the Munhall plat map
For land around Homestead, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
The viewer Allegheny County publishes
Your first stop is the Allegheny County ArcGIS parcel map; it covers each assessed parcel around Homestead and Whitaker. If you only know roughly where the land is, zoom in from Whitaker and select the outline. For a parcel near Homestead, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Land outside a subdivision
Rural land near Whitaker that was never subdivided may have no plat at all; look for a recorded survey for land near West Homestead.
Getting your bearings
Pittsburgh is the county seat, which is where the courthouse records live. You'll also find West Homestead, Whitaker, Homestead, and Rankin, each with its own cluster of lots. Roughly 1,224,825 people call Allegheny County home (Census Bureau estimate, 2023) on about 730 square miles. Allegheny County dates to 1788, and some chains of title near Rankin are long. Landmarks such as Allegheny River and Monongahela River help you orient on the aerial around Whitaker.
Amended plats
An amended plat may change lots around Whitaker, so check for later filings; vacated streets or alleys also get recorded.
Legal descriptions in Pennsylvania
Rural deeds near Whitaker are often described by metes and bounds, which trace the boundary call by call. Subdivision lots in Rankin refer to a recorded plat, which is simpler to follow. Copy the legal description from the record for the parcel near Swissvale before you request a deed or survey.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Whitaker, but coverage can be spotty out of town. A printout of the tract near Braddock keeps working without signal.
What the map can't tell you
Listed acreage is a tax-roll number; just a licensed surveyor establishes the real lines on land around Braddock. For a parcel near Rankin, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Munhall and the county around it
Munhall lies within Allegheny County, Pennsylvania, and the county assessor maps its lots. Local government in Munhall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits near Braddock generally answers to county rules rather than the town's.
Two different maps
If the tax map and plat differ near Swissvale, go with the plat and a surveyor's work.
Lots, blocks and easements
Easements on the plat near Braddock can block a shed or pool; check the plat notes and any covenants.
Who handles what
If the acreage or value on a parcel near Whitaker looks off belong with the county assessment office, since that office keeps the assessment data. Building or septic questions for a lot near Whitaker need the planning or permitting office, and the answer depends on jurisdiction.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements covering ground around Whitaker are filed with the Recorder of Deeds. Inherited tracts around Rankin can go back through several deeds, so a title company can sort it out if money is changing hands.
Ordering the Munhall plat map
For land near West Homestead, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
Neighboring parcel maps
Allegheny County meets Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County, all with their own assessor records. A tract near the line by Whitaker can show up in two county records, so open the neighboring map too. Closer to Whitaker, the Platbookmapper state page lists each neighboring county map across Pennsylvania.
