The Beaver County tax map is the official parcel record maintained by the Beaver County Assessment Office, and you can view it for free through the county’s InfoAtlas GIS portal or request a physical copy at the Assessment Office inside the courthouse at 810 Third Street in Beaver, PA. The online viewer lets you search by address, owner name, zip code, or parcel ID and shows lot lines, dimensions, and neighboring parcels against either a line drawing or aerial imagery.
Viewing the Map Online
Beaver County’s interactive GIS portal, InfoAtlas, is hosted at gis.mbakerintl.com/beavercountyinfoatlas and linked from the county homepage.1Beaver County, Pennsylvania. Beaver County It offers layers for parcels, aerial imagery, and historic landmarks. Before the map loads, you have to accept a disclaimer stating the data is informational and does not carry the accuracy of a professional survey.2Beaver County, Pennsylvania. Beaver County Geo Hub
The county runs a second site at propertyrecords.beavercountypa.gov that handles assessment values and tax claim data rather than map visuals.3Beaver County, Pennsylvania Property Records. Beaver County Property Records If you want to see the parcel on a map, use InfoAtlas. If you want the assessed value or tax status, start with property records.
Searching by Address, Owner, or Parcel ID
The portal supports four search methods: street address, zip code, owner name, and parcel ID. Parcel ID is the most reliable because it points to exactly one lot. You’ll find yours on your annual tax bill or on a recorded deed.
If you don’t have the parcel number, an address search works well. Enter just the house number and street name, without extra punctuation or abbreviations that can confuse the system. Owner-name searches help when you know who holds the land but not where it sits. Names are indexed exactly as they appear on official documents, so a middle initial or a suffix matters, and the Recorder of Deeds notes that multiple owners in the county may share a name, so cross-reference with a municipality or street when results are ambiguous.4Beaver County, Pennsylvania.

What the Interactive Viewer Shows You
Once you land on a parcel, the viewer draws it against the surrounding area with clear boundary lines. You can zoom in to see dimensions along each side, pan across to check neighboring lots, and switch between the standard line drawing and aerial satellite imagery. The satellite view is useful for spotting structures, driveways, and tree lines that a line drawing won’t show.
Adjacent parcel numbers appear on the map, so you can quickly identify the lot next door or trace how a block is subdivided. Most viewers include a measurement tool for estimating distances on screen. Those numbers are approximate. For anything involving construction setbacks or fence placement, you need a licensed survey, not a GIS measurement.
A Tax Map Is Not a Legal Boundary
The most important thing to understand before you act on anything you see: a tax map is a tool for calculating property taxes, not a definitive record of where your land begins and ends. County staff who maintain these maps are not surveyors, and the underlying data relies on historical records that can contain gaps or outdated measurements.5Davis Engineering & Surveying, LLC. Tax Maps Are Not Legal Boundaries The county’s own GIS disclaimer says as much.
People build fences, pour driveways, or plant gardens based on what the viewer shows, then discover during a later survey that the line is several feet off. That opens the door to neighbor disputes and trespassing claims. If you’re buying property, building near a boundary, or resolving a disagreement with a neighbor, a boundary survey from a licensed professional is the only reliable way to establish the legal edges of your land.5Davis Engineering & Surveying, LLC. Tax Maps Are Not Legal Boundaries
Public tax data is also typically updated once a year. Boundary changes from subdivisions, lot-line adjustments, or new recordings during the current year may not appear until the following calendar year.
Requesting a Physical or Certified Copy
The Assessment Office handles requests for physical tax map copies. It’s inside the Beaver County Courthouse at 810 Third Street, Beaver, PA 15009, open Monday through Friday from 8:30 a.m. to 4:30 p.m.6Beaver County, Pennsylvania. Assessment Office – Beaver County Courthouse Call ahead at 724-770-4480 to confirm what you need before making the trip. Credit card payments can be made by phone for certain services.
If you can’t visit in person, contact the office about a mail-in request with the parcel details and any required fees. The county has not published a standardized fee schedule for map copies online, so calling before you send anything saves time. Certified copies, which title companies and attorneys sometimes need for closings or court filings, generally cost more than a standard printout and take longer to process.
How the Map Connects to Your Tax Bill
The tax map exists to support one thing: the assessment that determines your bill. Every parcel carries an assessed value set by the Assessment Office under Pennsylvania’s General County Assessment Law.7Pennsylvania General Assembly. The General County Assessment Law Your annual tax equals that assessed value multiplied by the combined millage rate from three taxing bodies: Beaver County, your municipality, and your school district. The county publishes the millage table each year, and the 2026 version is on the county’s website.8Beaver County, Pennsylvania. 2026 Tax Levies County-Local-School Total Millages
Millage rates vary significantly across municipalities, so two homes with identical assessed values in different parts of the county can produce very different bills. When you’re comparing properties or evaluating a purchase, pull the millage table alongside the tax map to get the full picture.
If the assessed value on your parcel looks too high compared to what the property would actually sell for, you can appeal to the county Board of Assessment Appeals. For Pennsylvania counties outside Philadelphia and Allegheny, the annual filing deadline is August 1; miss it and you wait a year.
Cross-Referencing Deeds and Flood Zones
Tax maps rarely tell the whole story. The Beaver County Recorder of Deeds maintains an online index of recorded documents going back to 1800, searchable by party name, document date, book and page number, or instrument number.9Beaver County, Pennsylvania. Online Search – Beaver County Recorder of Deeds That’s where you confirm the chain of title, check for easements, and verify that the deed description matches what the tax map shows. The Recorder’s office recommends verifying anything you find in the online index against the original paper or imaged copy of the recorded instrument.
For any parcel near the Ohio, Beaver, or a tributary river, flood risk is a practical concern the tax map won’t address. FEMA maintains the National Flood Hazard Layer, a geospatial database you can download as shapefiles from the FEMA Flood Map Service Center and overlay against parcel data.10FEMA.gov. Flood Data Viewers and Geospatial Data Parcels in zones starting with “A” or “V” are classified as high risk, and a federally backed mortgage will require flood insurance. Zones labeled “X,” “B,” or “C” are lower risk and don’t trigger that requirement. Checking a parcel’s flood designation before you buy can save thousands in annual premiums and prevent a surprise at closing.
