Hunting for the latest Beaver County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Hazen. What this county guide covers: what's in a plat book, where to find editions, and the free online map that stays current for land near Frisco.
Getting started with the Beaver County plat book
With a lot near Ambridge, a plat book is a privately published atlas, showing rural owners and tract lines, often organized by township.
The free map to start with
Lots and tracts near Ambridge are published on the Beaver County parcel viewer, which opens without registering. Closer to Frisco, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Bridgewater, copy the parcel ID from that panel; each clerk in the county will want it.
Why people still buy them
Buyers and seed dealers around Beaver Falls rely on them to see ownership across many tracts at once.
Which office to call
If the acreage or value on a parcel near Fombell looks off go to the county assessment office, since that office keeps the assessment data. Zoning, permits and septic questions near Aliquippa go to planning, building or health offices, and the answer depends on jurisdiction.
Buying or borrowing a copy
Older editions near Aliquippa turn up in libraries and historical societies, which helps when tracing a farm's history.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a tree line near Bridgewater can sit a few yards off the line on screen. Out toward Cannelton, records update in batches, so a deed recorded last month can take weeks to appear.
Legal descriptions in Pennsylvania
Rural deeds near Ohio River Islands National Wildlife Refuge are often described by metes and bounds, which trace the boundary call by call. Platted lots around Fombell refer to a recorded plat, making them easier to find. Write down the legal description for the tract near Ambridge before you request a deed or survey.
Deeds, plats and who keeps them
For property near Aliquippa, the map is an index, not the title: deeds, plats and easements for parcels in the county are filed with the Recorder of Deeds. For a tract near Beaver Falls, inherited tracts in the county can sit on several deeds, so a title company earns its fee before a purchase.
Using the parcel viewer instead
The Beaver County parcel viewer is updated more often than any atlas, for tracts near Raccoon Creek State Park.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Cannelton, but coverage can be spotty out of town. A printout of the tract near Baden helps when you meet an owner or agent.
Not the same thing
Out toward Cannelton, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the Recorder of Deeds is a legal document, and the atlas is just a guide.
Places you'll see on the map
Beaver holds the county offices, where most land records are kept. Other places on the map include Aliquippa, Beaver Falls, Ambridge, and Baden. Around 165,631 people call Beaver County home (Census estimate, 2023) on roughly 435 square miles. Beaver County was organized in 1800, so old deeds can run back a long way. Landmarks such as Ohio River Islands National Wildlife Refuge are easy to spot when you zoom out from Cannelton.
When a parcel crosses a boundary
The county borders Columbiana County, OH, Allegheny County, Butler County, Lawrence County, and Washington County, all with their own assessor records around Cannelton. Ground near Big Beaver that runs to the line may be split in two county records, so check the neighboring map too. For acreage around Ambridge, the Platbookmapper state page lists each bordering county map for Pennsylvania.
