If a legal description for land in Ambridge cites a lot number, you'll need the Ambridge plat map to make sense of it. What this Ambridge guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Ambridge plat map
For a subdivision near Baden, the deed usually cites the plat; that makes the request quick.
Opening the official parcel viewer
Begin with the Beaver County parcel viewer; it covers each tax parcel in the county, Baden included. Closer to Aliquippa, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For a parcel near Aliquippa, the parcel card usually lists the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Where Ambridge fits in
Ambridge sits in Beaver County, Pennsylvania, which means parcel data comes from the county. If you're looking near South Heights, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the town limits toward Economy often answers to county rules, not municipal ones.
Land outside a subdivision
Rural land near Freedom that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Before you lean on the lines
Tax maps are drawn for assessment, not surveyed, so a fence near South Heights can sit a few yards off the line on screen. For land near Baden, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Offices that can help
Questions about value or the owner field for land near Aliquippa go to the county assessment office, which maintains the tax roll. Building or septic questions for a lot near Freedom are for the local planning and health departments, depending on whether the land is inside town limits.
The paper trail behind a parcel
Before you sign anything, request the recorded deed from the Recorder of Deeds; the parcel map near Conway only summarizes it. If you're looking near Baden, have ready the document number shown in the record panel to skip a name search.
Recorded plat or GIS layer
The tax map on the Beaver County parcel viewer is a summary, whereas the plat carries surveyed dimensions.
When a plat changes
An amended plat may change lots around South Heights, so check for later filings; street vacations show up in the records too.
What a plat shows
For property near Aliquippa, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Legal descriptions in Pennsylvania
Older tracts around South Heights commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Subdivision lots in Aliquippa refer to a recorded plat, making them easier to find. Write down the legal description for the tract near Freedom when you talk to a surveyor.
When a parcel crosses a boundary
Beaver County touches Columbiana County, OH, Allegheny County, Butler County, Lawrence County, and Washington County; every one of them runs a separate parcel map. Acreage along the edge near Aliquippa can be split across two assessors' files, so check the adjacent map as well. For acreage around Aliquippa, our state page links every bordering county map across Pennsylvania.
Getting your bearings
Beaver holds the county offices, which is where the courthouse records live. Smaller places on the map include South Heights, Aliquippa, Baden, and Economy, each with its own cluster of lots. About 165,631 people live in Beaver County (Census estimate, 2023) across roughly 435 square miles. Beaver County dates to 1800, and some chains of title near Baden are long. Features like Ohio River Islands National Wildlife Refuge make handy reference points on the map near Freedom.
Online indexes and office visits
On ground around South Heights, some counties put plat images online, while others require a visit or a request; small fees are common.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Baden, but coverage can be spotty out of town. A printout of the tract near Aliquippa is a good backup.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
