The math for a typical Carnegie Borough home
The median residential assessment in Carnegie Borough is $91,100. Because the county still uses 2012 values, the Board applies the Common Level Ratio in appeals: at 49.3%, that assessment implies the county thinks the typical home would sell today for $184,787.
Recent validated sales in Carnegie Borough (117 since 2024-10-28) run a median of $168 per square foot, which puts the typical home near $233,467. At that value the assessment should be about $115,099.
For the median home the assessment is already at or below the CLR target, so appeals in Carnegie Borough turn on the specific house: the 18% flagged here sit well above their neighbors on a per-square-foot basis.
When and how to appeal
Allegheny County's annual appeal window for tax year 2028 is expected to run July 1 to September 1, 2027, matching the 2027 window. Appeals are filed with the Board of Property Assessment Appeals and Review (BPAAR), heard by telephone, and decided on evidence submitted at least ten days before the hearing: comparable sales, a recent appraisal, or your own purchase price. The school district and municipality receive notice and may present their own evidence.
If you bought recently and your purchase price times 49.3% is well above your assessment, expect the opposite: Carlynton can file to raise you. 21 Carnegie Borough buyers since 2024-10-28 are in that position.

Figures are computed from Allegheny County assessment and sales records published through WPRDC (extract as of 2026-10-30), the 2027 Common Level Ratio of 49.3% from the Board of Property Assessment Appeals and Review, and 2026 millage rates from the county's community profile pages. "Likely over-assessed" means the assessment exceeds the neighborhood's median sale price per square foot times the home's finished area times the CLR by at least 10 percent, with at least $300 a year at stake. This is an estimate, not an appraisal or legal advice. Any party, including the school district, may appeal and argue for a different value.
