Allegheny County Property Appraiser Search: Assessments, Parcel Map & 2026 Taxes
If you searched for the Allegheny County property appraiser, Pennsylvania uses different terminology. The county office responsible for assessed property values is the Allegheny County Office of Property Assessments.
The county’s Real Estate Portal lets you search by street address or parcel number, review assessments, building information, owner history and tax information. Allegheny County GIS provides map-based parcel research, while the Treasurer handles county real estate tax payments.
Allegheny County is also unusual because assessments still use a 2012 base-year methodology. Understanding that system—and the common level ratio used in appeals—is essential before comparing the assessment shown online with today’s sale prices.
Property Assessment, Tax Payment and Deed Records Are Handled Separately

How to Search Allegheny County Property by Address or Parcel Number
The public Real Estate Portal supports address and parcel-number searches. Its address-search format is more particular than a normal web search, so entering less text can actually produce a better result.
Open the official Real Estate Portal
Start with the county’s public property database for assessments, owner information, building data and tax information.
Open Allegheny County Property SearchUse the parcel number when you have it
The parcel ID, often referred to as lot and block information, is the strongest way to distinguish one property from similarly addressed parcels.
For address searches, leave out the street suffix
The county specifically instructs users not to include suffixes such as “Street,” “Dr.” or “Cir.” in the street-name field.
Use municipality only when it helps narrow the result
The municipality field is optional. If you are unsure whether the parcel is in Pittsburgh or a surrounding municipality, leave it blank and compare the returned properties.
Confirm the parcel before using its assessment
Match the parcel ID, street address, municipality and property characteristics before using the values for a tax estimate or appeal.
After opening the Real Estate Portal
- Choose address or parcel-number search.
- For an address, enter the house number and street name without the street suffix.
- Leave municipality blank if you are uncertain.
- Open the matching result and verify the parcel ID.
- Use the tabs on the parcel record for assessment, owner, building, tax and appeal information.

Allegheny County GIS: Parcel Information, Layers, Measurements & Printable Maps
The county GIS viewer is useful when the address search alone does not explain where a parcel sits. It can display parcel information, switch map layers, measure distances or areas and create a printable map.
Good Uses for the GIS Viewer
- Locate a parcel visually
- Compare adjacent parcels
- Search an unfamiliar address
- Measure approximate distance or area
- Turn county map layers on and off
- Create a printable reference map
Do Not Treat GIS as Final Proof Of
- Surveyed boundary lines
- Legal ownership
- Easements
- Buildable area
- Zoning approval
- Title status
After opening the GIS page
- Select the county GIS Viewer from the web-applications section.
- Search the property address.
- Confirm the parcel against the Real Estate Portal parcel ID.
- Turn on only the layers needed for your research.
- Use survey, deed or planning records for legal conclusions.
Why an Allegheny County Assessment May Look Far Below Today’s Sale Price
Allegheny County uses a 2012 base year, with January 1, 2012 as the base-year valuation date. The last countywide reassessment took effect for tax year 2013.
That means the assessment shown in the public portal is not intended to represent today’s open-market sale price. Under the county’s base-year system, assessments generally remain tied to 2012 values unless a recognized event changes the assessment.
Events that can change a property’s assessment
- Omitted property information
- Mathematical or clerical errors
- Physical changes such as construction or demolition
- Subdivision activity
- Building permits and improvements
- Interim assessments requested for new construction or major improvements
- Catastrophic-loss adjustments when statutory requirements are met
Allegheny County Appeal Deadline, 49.3% Common Level Ratio & Telephone Hearings
The annual appeal window for tax year 2027 ran from July 1 through September 1, 2026. As of this update, the regular filing period has closed.
The Board of Property Assessment Appeals and Review states that the 2027 common level ratio is 49.3%. The Board applies this factor to current market value in appeals beginning in September 2026.
What happens after an annual appeal is filed
BPAAR schedules the hearing
Residential hearing notices are mailed at least 14 days in advance; commercial notices receive at least 21 days.
Submit evidence before the hearing
The county’s current hearing guidance requires evidence to be submitted two days before the scheduled hearing.
Participate by telephone
Current BPAAR appeal hearings are conducted telephonically using the contact information supplied for the appeal.
Wait for the written decision
The Board does not issue the decision at the hearing. The disposition is mailed and can also be tracked through the Real Estate Portal.
After opening the appeals page
- Confirm whether you need an Annual Appeal, Special Appeal or Late-Filed request.
- Open the relevant instructions and form.
- For a filed appeal, monitor the hearing notice and parcel Appeal Status.
- Submit evidence within the required pre-hearing period.
- Keep the mailed disposition because the next appeal deadline is measured from its mailing date.
If you disagree with the BPAAR decision
A dissatisfied party can appeal to the Court of Common Pleas, Board of Viewers, within 30 days of the disposition letter’s mailing date. The county currently lists a $135.25 non-refundable filing fee for that second-level appeal.

Allegheny County Property Appraiser FAQs
1. Does Allegheny County have an official Property Appraiser?
No. The Pennsylvania office performing the assessment function is the Allegheny County Office of Property Assessments. People searching for the Allegheny County property appraiser generally need this office or the county Real Estate Portal.
2. Can I search Allegheny County property records by owner name for free?
The public Real Estate Portal is built around address and parcel-number searches. Allegheny County’s paid subscription service adds owner-name searching, legal descriptions and additional tax information.
3. Why does my Allegheny County address search return no property?
Try entering the street name without suffixes such as Street, Dr. or Cir., as required by the county search. You can also leave the municipality field blank and choose the correct parcel from the returned results.
4. Why is my Allegheny County assessed value much lower than today’s market value?
Allegheny County still uses a 2012 base-year assessment system. The online assessment therefore is not intended to equal the property’s current 2026 sale price.
5. What is the Allegheny County common level ratio for 2027 appeals?
The Board of Property Assessment Appeals and Review lists the 2027 common level ratio at 49.3%. The Board states that this factor applies to current market value in appeals beginning in September 2026.
6. Can I still file a regular Allegheny County appeal for tax year 2027?
The regular 2027 annual appeal window ran from July 1 through September 1, 2026 and is now closed. A late-filed appeal may be possible only under limited circumstances, so review the county’s Late-Filed Appeal requirements.
7. What were the 2026 Allegheny County property tax deadlines?
The 2% discount period ended March 31, the gross or face-payment period ended April 30, and delinquency began May 1. Delinquent county tax receives a 5% one-time penalty plus 1% interest per month.
8. How much does the Allegheny County Act 50 homestead exclusion save?
Act 50 excludes $18,000 of assessed value from Allegheny County real property taxation. At the 2026 county rate of 6.43 mills, that equals $115.74 in county tax savings for most qualifying homeowners.
9. Where do I find Allegheny County deeds and mortgages?
Use the Allegheny County Division of Real Estate land-record services for deeds, mortgages, mortgage satisfactions, subdivision plans and related recorded documents. The assessment portal does not provide a complete legal ownership history.
10. Why is my new Allegheny County parcel missing from the Real Estate Portal?
If the parcel will be taxed by Allegheny County for the first time in 2027, the county says it may not appear until values are certified in January 2027. For assistance with a new parcel, the county lists LandHelp@AlleghenyCounty.US.
