Our Mission

The mission of the Office of Property Assessments is to deliver uniformity in base year assessments. We aim to supply accurate data resulting in fair assessments, as well as helpful, knowledgeable service in processing requests for information and assessment-related inquiries.

Base Year Methodology

Under Pennsylvania state law the last county-wide reassessment is the base year. Allegheny County’s last county-wide reassessment was in 2013. All values represent the estimated base year market value of the property as of January 1, 2013, unless otherwise updated due to permits, appeals, corrections, flood loss or catastrophic loss. Base year methodology allows similar homes to have similar assessments until the next county-wide reassessment.
