Allegheny County CAD property search, real estate records, tax bills and deed lookup guide
This guide helps Allegheny County property owners, Pittsburgh-area buyers, real estate agents and investors search official property records, verify parcel details, understand assessed values, check tax information, review deeds and avoid confusing Pennsylvania property records with Texas-style CAD pages.
Allegheny County does not use a Texas Central Appraisal District. Start with the official Real Estate Portal or Property Record Search for assessments, use the Treasurer for county real estate taxes, and use Land Records / Division of Real Estate resources for deeds, mortgages and recorded documents.
Quick answer: where to search Allegheny County property records
Use Allegheny County’s official Property Record Search or Real Estate Portal when you need parcel details, assessment records, building information, tax information, owner history, comparable properties, appeal status or parcel maps.
Use the Treasurer when your question is about county real estate tax bills, e-payments, receipts, due dates, tax relief or tax-related payment status. Use Land Records when you need deeds, mortgages, subdivision plans, block and lot maps or recorded real estate documents.

How to search Allegheny County property records step by step
The Real Estate Portal is the main place to begin. It is especially useful because one parcel record can connect assessment information, property details, maps, tax information and owner history.
Why “Allegheny County CAD” is not the correct official name
“CAD” usually means Central Appraisal District in Texas. Allegheny County uses Pennsylvania property-assessment and real estate portal systems instead. The search intent is valid, but the office name and process are different.
- Assessment values
- Property characteristics
- Building information
- Comparable properties
- Appeal status
- Address changes and corrections
- Texas protest rules
- Texas homestead exemption assumptions
- Tax payment receipts
- Recorded deed searches
- Mortgage satisfaction records
- Legal boundary surveys
What you can check in an Allegheny County property record
A property record can answer many questions, but it should not be treated as a legal deed, title report, survey or final tax receipt.
| Record area | What it helps verify | Practical user tip |
|---|---|---|
| Block and lot / parcel ID | Unique county property reference | Save this before calling any county office. |
| Owner history | Ownership names shown in real estate records | For legal deed proof, confirm through Land Records. |
| Property address | Situs/location address | Confirm municipality because many streets repeat across Allegheny County. |
| Building information | Property characteristics and structure details | Check square footage, use, condition, permits or major physical changes. |
| Assessed value | Value used for assessment purposes | Do not compare it directly to current Zillow-style market estimates without understanding base-year methodology. |
| Comparable properties | Nearby property comparison context | Use similar municipality, property type, age, size and condition. |
| Tax information | Tax-related information connected to the record | Use Treasurer resources for payment status and receipts. |
| Maps / property lines | General parcel map context | Use maps for orientation, not as a legal boundary survey. |
