The Blair County tax map is available free through the county’s online GIS Parcel Viewer, and it works alongside a separate assessment search portal that pulls up valuation and tax data for any parcel. Together, the two tools let you find a property by owner name, street address, Parcel Identification Number, or Control Number, see its boundaries on aerial imagery, and view the assessed values that drive the tax bill. Both are open to the public through the Blair County website, and the county maintains the underlying records under Pennsylvania’s Consolidated County Assessment Law.1Pennsylvania General Assembly.

How to Search Blair County Property Records
The assessment database accepts four kinds of input. You can search by owner name (enter last name first), by street address, by Parcel Identification Number, or by Control Number.
Those last two are not the same thing, and mixing them up is the most common reason a search comes back empty. The Parcel Identification Number, sometimes called the Map Number, identifies the parcel’s location on the assessment maps. The Control Number is a distinct eight-digit code tied to the property’s record in the county’s computer-assisted mass appraisal database.2Blair County. CAMA Data You’ll find the Control Number printed on the back of your county tax bill.3Blair County, PA. Blair County Online Services
Either identifier will pull the correct record if entered in the right field. If you don’t have a tax bill on hand, searching by street address is the simplest route.
What the Assessment Record Shows
Pull up a parcel and the record splits the value into two pieces: assessed land value and assessed building value. Add them together and you get the total assessment, which is the figure local taxing bodies use to calculate your annual property tax. The record also lists the property’s classification, typically residential, commercial, or agricultural, and that classification affects which millage rates apply.
The record identifies the specific school district and municipality that tax the property. That matters, because each taxing body sets its own millage rate and those rates vary across the county. You’ll also see descriptions of improvements such as additions or outbuildings that factored into the building value.
Using the GIS Parcel Viewer
Blair County’s GIS department runs an interactive Parcel Viewer on its website, along with a broader GIS Portal for more advanced work.4Blair County. Blair County – Geographic Information Services The Parcel Viewer overlays parcel boundaries on aerial imagery, so you can see where property lines fall relative to structures, roads, and vegetation. You can zoom, toggle layers, and click any parcel to open its assessment data.
For flood risk, the county links out to FEMA’s national flood hazard mapping tool, which shows whether a parcel sits inside a designated flood zone. That’s a separate application from the Parcel Viewer and it opens in a new window.
If you prefer static reference maps, the Assessment Office also publishes Assessment Map Books through the county website, indexed by municipality.5Blair County. Assessment Map Books They’re useful for finding Map Numbers when you’re working offline.
What the Map Cannot Be Used For
The GIS map is not a land survey. Blair County’s own disclaimer states that the county accepts no responsibility for errors, omissions, or positional inaccuracies, and that the map should not be construed or used as a legal description of any property.4Blair County. Blair County – Geographic Information Services
If you need to settle a boundary dispute, place a fence on a property line, or verify exact lot dimensions for a real estate closing, hire a licensed surveyor. The Parcel Viewer is built for general orientation and tax research, not legal boundary determination.
Turning the Assessment Into a Tax Estimate
Your property tax bill is the product of two numbers: the total assessed value from the county records and the combined millage rate set by the taxing bodies with jurisdiction over your parcel. A mill equals one-tenth of a cent, so 10 mills means $10 in tax per $1,000 of assessed value. Most Blair County properties are taxed by three entities: the county government, the municipality, and the school district, each imposing its own rate.
Blair County publishes current millage rates for every municipality and school district on its Assessment Office page.6Blair County. Tax Collectors and Millage Information Rates can change annually when taxing bodies adopt new budgets, so check the current year’s schedule before estimating what you owe. The gap between the lowest and highest combined rates across the county can be substantial, which is worth knowing if you’re comparing properties in different municipalities.
Appealing Your Assessment
If the assessed value looks too high, or is out of line with comparable properties, or reflects the wrong property classification, you can file an appeal with the Blair County Board of Assessment Appeals. The annual filing deadline is August 1. If you receive a new assessment notice outside the annual cycle, you have 40 days from the date of that notice to appeal.7Blair County, PA. Forms and Appeals
You submit the official Assessment Appeal Form, available on the Blair County Assessment Office website. The Board conducts hearings under its published Assessment Appeal Rules and Regulations. A strong case usually rests on comparable sales data for similar properties in your area, plus any independent appraisals or documentation of condition issues that would affect value. If you disagree with the Board’s decision, you can appeal further to the Blair County Court of Common Pleas.
Looking Up Deeds and Prior Sales
The tax map and assessment records tell you who currently owns a property and what it’s worth for tax purposes. They do not contain the full chain of title, prior sale prices, or recorded easements.
For those, Blair County’s Register of Wills and Recorder of Deeds office maintains a separate database through the Landex platform.8Blair County. Register of Wills and Recorder of Deeds You’ll need to create a Landex account to search recorded documents. Cross-referencing the Parcel Identification Number from the assessment records with the deed book and page number in the Recorder’s system lets you trace ownership history and verify legal descriptions.
