Village-Wide Property Assessment Revaluation

Click HERE for an interactive map of assessment values and recent residential sales

The Village has contracted with Associated Appraisals to conduct a revaluation of all properties. This is a Village-wide complete and thorough review of all property assessments.  Value adjustments will be made where necessary to guarantee that all property is assessed at market value. This ensures that taxes are distributed equitably. The last Village-wide revaluation was over 15 years ago and Grafton has fallen outside the acceptable range of assessed to equalized valuation ratio. State law requires this ratio to be within 10% of the 100% equalized value set by the State.
