This is not a government website. Allegheny County doesn't run, fund or endorse it. The official record lives on the county's Real Estate Portal, and that is the one to rely on for anything legal or financial.
What it does
The county publishes a great deal about every parcel: who owns it, what it's assessed at, what it sold for, whether the county taxes are paid. The official portal splits that across eight tabs and expects an exact address or parcel ID before it shows anything.
Parcel Finder puts the same facts on one screen. Its search box forgives partial addresses, and it accepts parcel IDs and deed references in whatever form you have them. The map draws every lot line in the county, so you can tap a property instead of typing.
Where the data comes from
- Parcel records. Address, assessed value, last sales, building details and school district come from the Allegheny County Office of Property Assessments, published as open data through the Western Pennsylvania Regional Data Center. This copy is current to October 30, 2026.
- Lot lines. Outlines come from the county's parcel boundary file, also published through the data center.
- Owner, tax and comparable sale details. These are read from the county's Real Estate Portal at the moment you open a property, so they are as current as the county's own page.
- Photos. The picture on each property is the county's own assessment photo.
- Map tiles. Street and aerial maps come from Esri.
What it leaves out
The county's open data doesn't include owner names, and a county ordinance keeps name search off its free site. Parcel Finder follows the same line. It shows the owner of a property you look up, but it won't list properties by owner. For that, the owner button on the map opens the county's own deed index, where name search is allowed.
It also shows only the county's real estate tax. School district and municipal taxes are billed separately and aren't in the county's file.
Accuracy
Every figure here is the county's. If something looks wrong, it is almost always wrong at the source, and only the county can change it. Check the official portal before you rely on a number, and treat assessed values as what they are: 2012 base-year figures, not prices.
