Modernizing Property Tax Assessments in Allegheny County
Allegheny County has not conducted periodic, regular property reassessments since the 1970s. As a result, assessed values have drifted further and further away from actual market values, creating inequities for taxpayers and making the property tax system less transparent and less efficient.
Today, Pro-Housing Pittsburgh is releasing our latest report:
Modernizing Property Tax Assessments in Allegheny County
This report examines how modern, open-source assessment methods could be used to produce fair, transparent, and affordable countywide reassessments.
Using publicly available data and open-source valuation models, we estimate updated assessments for residential properties across Allegheny County, evaluate their quality against International Association of Assessing Officers (IAAO) standards, and estimate the cost of implementing a regular reassessment program.
Modern automated valuation methods can produce assessments substantially closer to market value than the current system using publicly available data.
