Allegheny County Property Search: Records, Tax & Map 2026
Find Allegheny County property assessments, parcel numbers, owner history, tax information and property maps using the official county records system.
Serving Pittsburgh and communities throughout Allegheny County, this guide explains where to look for assessed values, property tax bills, recorded deeds and boundary maps—and how to resolve common search problems.
How to Find Allegheny County Property Records
The quickest way to search a property in Allegheny County is the official Real Estate Portal. Start with the street address or parcel number, select the matching property, and review the record’s assessment, tax, sale history, building and map information.
Property Assessment
Find the assessed value, land and building values, property characteristics, parcel identification number and available ownership history.
Open assessment search ↗Property Taxes
Review county real estate tax information, payments, taxable values and tax-year details associated with a selected property.
Find tax details ↗Parcel Maps & Deeds
Locate the parcel map in the property portal, use county GIS for geographic information, or visit land records for recorded documents.
Open land records ↗Step-by-Step: Search by Address or Parcel Number
Allegheny County’s portal supports address and parcel-number searches. You can start with an address even if you do not know the owner’s name or the tax parcel ID.
Open the official Real Estate Portal
Visit realestate.alleghenycounty.us/search. This is the county’s searchable public property system.
Choose your search method
Select an address search or parcel-number search. If you already have a lot-and-block or parcel identification number from a prior bill or deed, it may provide the most precise match.
Enter the street details carefully
For an address search, supply the house number and street name. The county instructs users not to include street suffixes such as Street, Drive or Circle in the street-name field. The municipality selection is optional.
Select the correct property
Compare the returned address, municipality and parcel identifier. Check for similar street names, neighboring parcels or multiple units before assuming the first result is correct.
Review the available record tabs
Depending on the property, review general information, assessed values, tax information, building characteristics, owner history, sales, comparable properties, maps and appeal status.
Verify and save the information you need
Record the parcel ID and applicable tax year. If you need the actual recorded deed, certified document or legally reliable boundary information, use the appropriate additional county service rather than relying only on the assessment screen.
What Records Can You Find?
There is no single document that answers every property question. Allegheny County maintains assessment data, tax records, land documents and GIS information through related but distinct county services.
| Record | Information available | Where to look |
|---|---|---|
| Parcel record | Parcel ID, street address, municipality and property classification | Real Estate Portal |
| Assessment | Land value, building value and county assessed value | Office of Property Assessments |
| Tax information | County tax-year information, billed amounts and payment history where available | County tax portal / Treasurer |
| Ownership history | Owner information and available recorded transfers | Real Estate Portal / Land Records |
| Deeds | Recorded deed documents and recording references | Division of Real Estate |
| Mortgages | Recorded mortgage documents and satisfactions where available | Division of Real Estate |
| Parcel maps | Mapped lot outlines and geographic context | County GIS / parcel map |
| Assessment appeal | Appeal filing status and related information | Office of Property Assessments / BPAAR |
Some public records may be available online without charge, while document images, copies and enhanced search services may involve fees or access requirements.
Understanding Allegheny County Property Assessments
An assessed value is the valuation used for property-tax administration. It is not necessarily the same as a property’s current resale price, a lender’s appraisal or the amount a buyer recently paid.
Land and Building Values
The county record may break a property’s value into separate land and building components. The combined value helps explain how the total assessment is constructed.
Building descriptions, lot area and other property details may help you identify possible errors in the record.
Market Value vs. Assessed Value
Allegheny County’s property portal displays base-year market values and county assessed values by tax year. The values should be read in the context of the county’s assessment rules and any subsequent corrections or appeal decisions.
A comparable property or recent sale may provide useful context, but does not automatically establish the correct assessment for tax purposes.
Why Your Assessment Might Change
A change can result from assessment proceedings, a successful appeal, a qualifying property change, correction of existing information or other applicable county valuation action. Do not assume a change in the tax bill means that the underlying property assessment increased.
Allegheny County Property Tax Search for 2026
County property taxes are based on the applicable taxable assessment and county millage. In 2026, the county real estate tax rate shown by Allegheny County is 6.43 mills, equivalent to $6.43 per $1,000 of taxable assessed value.
Example: Calculating County Real Estate Tax
For illustration, consider a property with a taxable assessed value of $150,000.
This is an illustrative county tax amount before any applicable discounts, penalties or other adjustments. It does not include separate municipal or school-district taxes.
Use the actual parcel’s tax information for an accurate current bill. A property’s eligible exemptions and tax payment timing can change the amount owed.
County, Municipality and School District Taxes
Allegheny County real estate owners may be subject to more than one real estate taxing authority. Pittsburgh, other municipalities and school districts have their own tax arrangements and may use different billing or collection processes.
| Tax category | Who administers it | What to verify |
|---|---|---|
| County real estate tax | Allegheny County | County assessment, applicable exclusions, county bill and payment |
| Municipal real estate tax | City, borough or township | Municipal millage, collector and payment dates |
| School real estate tax | Applicable school district | School rate, homestead/farmstead treatment and tax collection |
How to Check a Tax Bill or Payment
- Find the parcel in the official Real Estate Portal.
- Open the property’s tax information.
- Confirm the tax year before reviewing the payment status.
- Check the balance, discount or penalty information displayed for the parcel.
- Use the official payment instructions rather than sending money to an unfamiliar third-party site.
- If you need a receipt, check whether the portal provides a downloadable paid-tax record.
The county tax portal explains that available online receipts generally appear after processing and that older payments may require contacting the Treasurer. Delinquent tax balances may need separate verification with the responsible collector.
How to Find Property Owners, Deeds and Sale History
A property assessment record can identify the owner shown in county administrative records. However, a recorded deed provides the underlying instrument used to document a real estate transfer.
Basic Owner Lookup
Search by address or parcel ID and review the general information or owner history displayed by the county.
Additional owner-name search capabilities are available through the county’s enhanced real estate website access arrangements.
Recorded Deed Lookup
Use the Allegheny County Division of Real Estate’s land-record resources for recorded deeds, mortgages, subdivision plans and related historical records.
When available, copy the deed book and page references from the parcel record to assist with document research.
Online Deed Copies and Fees
Allegheny County’s online land-record document service provides deed images from 1993 onward and mortgage images from 1994 onward, according to its published online payment guidance.
| User category | Published online copy cost | Access |
|---|---|---|
| Casual user | $1 per page for up to 10 charged pages; additional pages within the document are free | Credit-card funding as needed |
| Commercial user | $0.50 per page for up to 10 charged pages; additional pages within the document are free | Online funded account |
These amounts apply to the published online copying options, not every certified copy, recording transaction or historical research service. Review the county’s current fee schedule before paying.

Can You Use the Tax Owner Name as Proof of Title?
No. An assessment owner field is useful for identifying a property, but does not replace a complete title examination. A recent sale may not yet be fully reflected in every county system, and ownership may involve trusts, estates, business entities or multiple parties.
For title questions, liens, easements, legal descriptions or a real estate closing, review recorded instruments and consult an appropriate Pennsylvania title professional or attorney.
Allegheny County GIS Maps and Property Boundaries
Parcel maps help you understand where a property is located relative to streets, neighboring lots and surrounding geographic features. Allegheny County provides mapping tools through its Real Estate Portal and GIS department.
Property Portal Map
After opening a parcel, review the map section to see the county’s parcel mapping information. This is particularly useful when comparing adjacent parcels or identifying a lot behind another street address.
Open parcel search and map ↗County GIS Viewer
The county GIS viewer offers address search, layers, zooming, area and distance measurement, basemap choices and printable maps.
Open county GIS tools ↗When a Property Map Is Most Useful
- Finding the parcel associated with a particular address.
- Comparing adjacent lot outlines before further research.
- Identifying nearby streets and municipal boundaries.
- Checking whether the correct lot or multiple parcels were selected.
- Locating parcel references to support a deed or assessment inquiry.
Property Assessment Appeals: Important 2026 Dates
Allegheny County permits qualifying parties to challenge assessed property values through the Board of Property Assessment Appeals and Review (BPAAR). The annual appeal deadline is tied to the tax year being appealed, not necessarily the year in which the appeal is filed.
The county states that filing a 2027 appeal affects the 2027 value and later years rather than retroactively changing the earlier tax-year assessment.
How the Appeal Process Works
Review the assessment and applicable filing window
Look up the property and compare its assessed value, record characteristics and relevant valuation evidence.
File using an approved county method
During an active annual filing period, the county supports online and other prescribed filing methods. The county says not to file annual appeals by fax.
Prepare evidence for the hearing
Depending on the dispute, documentation might include credible comparable sales, an appraisal, property photographs or evidence of incorrect building characteristics. Follow the hearing notice’s instructions and evidence deadline.
Receive the board’s determination
BPAAR can sustain, reduce or increase the assessed value based on the evidence and applicable valuation rules. A decision is not ordinarily issued during the hearing itself.
Consider further review when appropriate
If a party contests BPAAR’s decision, the county describes a further appeal to the Court of Common Pleas through the Board of Viewers. The stated filing period is 30 days after the decision letter’s mailing date, and court filing fees apply.
Annual vs. Special Appeals
The normal annual deadline is not the only possible property assessment procedure. Allegheny County also describes special appeals following certain written determinations issued by the Office of Property Assessments. A special appeal is not simply an unrestricted extension of the annual deadline.
Read the official rules for the particular notice or circumstance before deciding whether an appeal is still possible.
Check Official Assessment Appeal Rules ↗Property Tax Relief and Homestead Exclusions
Some Allegheny County property owners qualify for programs that reduce county property taxes. Eligibility must be established under the applicable program rather than assumed from age, disability or owner-occupancy alone.
Act 50 Homestead/Farmstead Exclusion
The county’s Act 50 program excludes the first $18,000 of assessed value from county real estate taxation for eligible properties, including qualifying owner-occupied primary residences.
At the stated 6.43-mill county rate, that exclusion represents $115.74 in county tax savings for a qualifying property receiving the full benefit.
Application deadline: March 1 for the exclusion to take effect for the relevant current and subsequent tax years. The county says approved owners generally do not need to reapply annually unless specified changes occur.
Act 77 Senior Citizen Tax Relief
Allegheny County describes a senior tax relief program providing a 30% reduction in the county tax bill for eligible residents.
Published requirements include being at least 60 years old, having annual income of $30,000 or less, and having owned and lived in the current Allegheny County residence for at least 10 years.
Additional rules and application requirements should be confirmed with the county.
Other relief may apply to certain qualifying properties under local economic revitalization or other exemption programs. School district and municipal treatment can differ from the county’s rules.

Before You Finish Your Property Search

If a tax balance, deed, assessment appeal or boundary question could affect a financial or legal decision, verify the result with the responsible public office before relying on it.
