Parcel boundaries are updated on a monthly basis as assessor information is updated in the MODIV database by the municipalities within Middlesex County. Parcel polygons for each municipality were created individually. After parcel development was completed for the neighboring municipality, property lines extending across municipal boundaries were aligned to help facilitate a seamless parcel layer. Parcels for each municipality were merged into a countywide parcel layer after all parcel development was completed for the County. Parcels are updated on a monthly basis.

The MOD-IV system provides for the uniform preparation, maintenance, presentation and storage of property tax information required by the Constitution of the State of New Jersey, New Jersey Statutes, and rules promulgated by the Director of the NJ Division of Taxation. MOD-IV maintains and updates all assessment records, and produces all statutorily required tax lists for property tax bills. This list accounts for all parcels of real property as delineated and identified on each municipality's official Tax Map, as well as taxable values and descriptive data for each parcel.
