The Tax Mapping Division of the Ontario County Real Property Tax Agency provides current, up-to-date tax maps for all sixteen towns, nine villages, and two cities incorporated in Ontario County.

Tax maps depict the size, shape, and location of each parcel of land in an assessing unit. The tax map is a graphic display of each assessing unit's land inventory and, as such, is considered essential to the formulation of an assessment roll. A working copy of the tax map is a valuable assessment tool which is utilized to record and analyze property transfers and to record topographical and other information pertinent to the valuation of land.

Our 675+ individual tax map sheets are maintained by three map technicians:
