Search by Address, Parcel ID or Owner Information
Allegheny County property records are easiest to search when you have a parcel ID or clean property address. Owner-name access may depend on account/subscription services, so address and parcel searches are the safest public starting points.
Search by address
Use the street number and street name first. Avoid apartment numbers, punctuation and extra words until you find the correct property.
Search by parcel ID
Parcel ID is the most accurate option. It helps connect the Real Estate Portal, tax records, GIS data, land records and appeal questions.
Search by owner information
The county’s property record search page notes that additional services can include the ability to search by owner name. If you only have an owner name, start with the public portal and check whether subscription access is needed.
Real Estate Portal Property Data and Owner History
The Real Estate Portal helps users review public property assessment data. The county states that property assessment records include tax information, building information, owner history, comparable properties, appeal status and maps.

Assessment Appeals and Value Questions
Allegheny County’s Real Estate Portal states that the annual appeal window for tax year 2027 will open on July 1, 2026 and close on September 1, 2026.

Allegheny County vs City of Pittsburgh Records
Pittsburgh properties are still inside Allegheny County, so county Real Estate Portal and Land Records tools are important for county parcel and deed research.
However, city-level matters such as certain permits, zoning, code issues and local city records may require City of Pittsburgh resources in addition to county records.
| Question | Use County? | Use City? |
|---|---|---|
| Parcel assessment and owner history | Yes, use Allegheny Real Estate Portal. | Usually no for county assessment data. |
| Deeds and mortgages | Yes, use Allegheny Land Records. | No for county recorded deeds. |
| County real estate tax | Yes, use Treasurer resources. | City/school taxes may also need separate confirmation. |
| Permits, zoning and code | Only for county map/property context. | Yes, check City of Pittsburgh when property is in Pittsburgh. |

Local Tips Most Guides Miss
- Parcel ID is the key: Save it from the Real Estate Portal before checking taxes, deeds or maps.
- Use owner history but verify deeds: Owner history is helpful, but legal title research needs recorded land documents.
- Check appeal dates every year: The 2027 window currently opens July 1, 2026 and closes September 1, 2026.
- New parcels may not appear immediately: The portal notes that properties first taxed in 2027 may not appear until values are certified in January 2027.
- Sales prices need context: The portal warns that latest recorded sales may include invalid or unusual sales such as sheriff sales or multi-parcel transactions.
- County tax is not the full tax story: Municipal and school taxes can matter during purchase or refinance.
- Use GIS for municipality clues: Allegheny County has many municipalities; map context can prevent wrong-record mistakes.
- Do not rely on detached-structure assumptions: The portal notes property data may not include minor detached structures such as sheds, garages or pools assessed to the parcel.
- Use official Land Records for mortgages: Mortgage satisfactions and recorded mortgage documents are land records, not assessment records.
- GIS is not a legal survey: Use licensed surveyors and recorded plans for exact boundary issues.
