How this compares to its street
This parcel's assessed value rose 26.5% between the last two rolls. Across the 28 comparable parcels on Byron Ln, the median rose 1.0%.
That is 25.5 points above its own street. A finished renovation, an addition, new construction, or a correction to a previously low assessment all do this, and none of them is an error.
If none of those happened here, ask the assessor what changed. Grievance season in Westchester has the deadlines; miss one and you wait a year.
