Hunting for the latest Butler County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Homeacre-Lyndora. What this Butler County guide covers: what's in a plat book, where to find editions, and how the county viewer fills the gaps.
Getting started with the Butler County plat book
For property near Cherry Valley, a plat book is a privately published atlas, with owner names on each tract, page by page across the county.
Where the parcel data lives
Go first to the PASDA Pennsylvania Tax Parcels viewer; it includes each tax parcel from Chicora to Bruin. When a rural tract has no street number, follow Interstate 79 on the aerial until the lines appear, then click inside the one you want. If you're looking near Moraine State Park, write down the parcel ID from that panel; every records desk in the county asks for it first.
Offices that can help
For assessment questions about property around McConnells Mill State Park belong with the county assessment office, the office behind the parcel record. Zoning, permits and septic questions near Fernway go to planning, building or health offices, town or county, depending on location.
A word on accuracy
For a home near Callery, listed acreage is a tax-roll number; just a licensed surveyor can set the real corners on the ground. Near McConnells Mill State Park, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Where to look for one
Libraries near Cherry Valley sometimes keep past atlases, which helps when tracing a farm's history.
Backing up the map with records
With a lot near Callery, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county are kept by the Recorder of Deeds. Inherited tracts around Lake Arthur Estates can trace back through several deeds, and a title company is worth hiring if money is changing hands.
Reading the legal description
Older tracts around Chicora are often described by metes and bounds, which trace the boundary call by call. Subdivision lots in East Butler are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Connoquenessing when you talk to a surveyor.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Homeacre-Lyndora, though signal can drop in rural spots. A screenshot of the parcel near Cherry Valley with its ID keeps working without signal.
Places you'll see on the map
Butler holds the county offices, home to the main records offices. You'll also find Bruin, Callery, Cherry Valley, and Chicora, each with its own cluster of lots. Around 198,413 people live in Butler County (Census Bureau estimate, 2023) spread over about 789 square miles. Butler County was formed in 1800, and some chains of title near McConnells Mill State Park are long. Landmarks such as Slippery Rock Creek and Moraine State Park make handy reference points on the map.
Between editions
Between printed editions, the PASDA Pennsylvania Tax Parcels viewer shows current owners, for tracts near Callery.
Neighboring parcel maps
Butler County meets Allegheny County, Armstrong County, Beaver County, Clarion County, and Lawrence County, all with their own assessor records. Ground near Slippery Rock Creek that runs to the line can show up across two assessors' files, so check the adjacent map as well. Out toward Lake Arthur Estates, the Platbookmapper state page links every bordering county map across Pennsylvania.
