Find Allegheny County Property Tax Records

Allegheny County is Pennsylvania's second most populous county, home to the city of Pittsburgh and more than 580,000 assessed parcels. The Office of Property Assessments administers valuations for all real estate in the county, and an extensive online real estate portal makes searching property tax records accessible from anywhere. Whether you are researching a potential purchase, verifying ownership, or reviewing your own assessment, Allegheny County's digital resources provide detailed property data including assessed values, ownership history, and building photographs. This guide walks through every major avenue for finding Allegheny County property tax records.

Allegheny County Assessment Office

The Office of Property Assessments is located on the third floor of the Allegheny County Office Building at 542 Forbes Avenue in Pittsburgh. This office is responsible for establishing assessed values for all 580,000-plus parcels in the county, a task that involves maintaining property record cards, coordinating field inspections, and managing the formal appeals process. Pennsylvania law under Title 72 of the PA Consolidated Statutes sets the framework for how assessments must be conducted, and Allegheny County's Office of Property Assessments operates within that statutory structure. The PA Department of Community and Economic Development provides technical assistance to county governments on assessment practices.

One notable aspect of Allegheny County's assessment landscape is the 2012 countywide reassessment, which remains the most recent full revaluation. This means current assessed values are based on market conditions from over a decade ago, which can create significant gaps between assessed and current market values for many properties. Property owners should be aware of the common level ratio published annually by the State Tax Equalization Board, as it reflects how the current assessed values relate to present-day market values and is directly relevant to the assessment appeals process.

How to Search Allegheny County Property Tax Records

Pennsylvania county assessment offices handle property records in accordance with state law, and the resources available at the county level vary considerably in depth and accessibility. The Pennsylvania Department of Community and Economic Development publishes guidance on how counties manage their assessment systems, and the image below from a comparable county office illustrates the type of public-facing assessment environment common across western Pennsylvania.

Allegheny County's own resources at alleghenycounty.us go well beyond a basic search portal, offering property photographs, building sketches, and ownership history that few other counties in the state provide.

The county's real estate portal at alleghenycounty.us/Real-Estate is the most comprehensive starting point for property research. Users can search by address or parcel number to retrieve a property's assessed value, ownership details, sales history, and physical characteristics. The portal goes beyond basic data by including property photographs and building sketches, which are useful for verifying that the county's records accurately reflect a property's actual condition and improvements.

Assessment-specific data, including current valuations and the history of value changes, is available through the Real Estate Valuations section. For legal documents such as deeds, mortgages, and liens, the county maintains a separate Court Records system that indexes recorded instruments by party name and document type. Searching both systems together gives a complete picture of a property's legal and financial status. The directory of PA county assessment offices provides additional context on how Allegheny County's resources compare to the other 66 counties statewide.

In-person access at 542 Forbes Avenue remains an option for those who prefer working with staff directly or need assistance navigating older records not fully digitized online.

The Pennsylvania Office of Open Records confirms that assessment records are presumed public under the Right-to-Know Law, so residents may request records without providing a detailed justification.

Allegheny County Property Tax Records and What They Include

Pennsylvania's assessment records are managed at the county level, and online search tools have expanded considerably in recent years across the commonwealth. The image below shows a representative county assessment office portal similar in structure to the tools Allegheny County provides through its real estate portal.

Each property record in Allegheny County captures a broad range of information. The assessed value is the most prominently referenced figure, as it directly determines the tax owed after applying the millage rates set by the county, municipality, and school district. Property record cards also document the land area, building square footage, construction type, number of rooms, and the year of construction. For residential properties, bedroom and bathroom counts are commonly included. Commercial properties receive additional detail about use type and income characteristics.

The real estate portal's inclusion of property photographs and building sketches makes Allegheny County's records more detailed than those found in many other Pennsylvania counties. These visual components allow researchers to confirm whether major improvements have been captured in the assessment and whether the records reflect the current state of the structure. Ownership history available through the portal shows prior owners and sale prices, which is valuable context when evaluating current assessed values against recent market activity. According to propertytax101.org, Pennsylvania's median property tax is approximately $2,223 on a median home value of $164,700, representing roughly 1.35 percent of home value statewide.

Note: Because Allegheny County's last countywide reassessment was in 2012, the relationship between assessed value and current market value varies considerably by neighborhood and property type.

Appealing Your Allegheny County Assessment

The county maintains a structured process for challenging assessed values before the Board of Assessment Appeals. Property owners must typically file by August 1 for the appeal to be heard in the current tax year, though the specific deadline should be confirmed with the Office of Property Assessments each year. The volume of appeals in Allegheny County is among the highest in Pennsylvania given the size of the county's property tax base and the extended period since the last reassessment.

A successful appeal generally requires documented evidence that the assessed value exceeds the property's market value when adjusted for the applicable common level ratio. Independent appraisals, recent comparable sales, and evidence of physical deficiencies in the property all serve as supporting documentation. The Pennsylvania Constitution's Uniformity Clause, found in Article VIII, Section 1, also allows appeals based on evidence of non-uniform assessments within the same class of property. If the Board of Assessment Appeals does not resolve the dispute satisfactorily, further appeal to the Court of Common Pleas is available through the PA Courts system. The Local Government Commission publishes resources on the appeals process that property owners may find helpful when preparing a case.

Property Tax Relief Programs in Allegheny County

Allegheny County property owners may qualify for several programs that reduce their tax burden. The Homestead Exclusion under Act 1 of 2006 lowers the taxable assessed value of a primary residence, and the Farmstead Exclusion under Act 72 of 2004 provides similar relief for qualifying agricultural buildings. Applications for both programs are processed through the Assessment Office.

The Allegheny County Treasurer administers the Senior Citizen Tax Discount program, accessible at alleghenycounty.us/treasurer. This local program complements the statewide Property Tax/Rent Rebate Program administered by the PA Department of Revenue, which provides rebates to seniors age 65 and older, widows and widowers age 50 and older, and disabled persons age 18 and older who meet income requirements. Combining county-level and state-level relief programs can meaningfully reduce the net tax owed by eligible senior homeowners in Pittsburgh and the surrounding municipalities. The PA Department of Education also distributes gaming revenue-based property tax relief to school districts throughout Allegheny County.

Note: Each relief program has its own application deadline and income threshold, so eligible residents should verify current requirements directly with the administering agency each year.

Allegheny County Court Records and Deeds

Deeds, mortgages, and liens affecting Allegheny County properties are recorded and maintained through the county's Court Records division. The Court Records portal provides online access to indexed instruments, allowing users to search by party name or document type to locate conveyances and encumbrances. This is the authoritative source for establishing a chain of title and identifying any outstanding liens that may affect a property.

For property transactions, title examiners and attorneys routinely use the Court Records system in conjunction with the real estate portal to assemble a complete picture of a property's legal status. Mortgages recorded with the Court Records division are indexed by borrower name and property address, making it possible to identify lenders and loan dates associated with any parcel. Judgment liens, which can attach to a property owner's real estate automatically upon entry in the court docket, are also searchable through this system. Combined with the assessment data in the real estate portal, the Court Records system gives researchers the fullest possible view of Allegheny County property tax records and ownership history.
