Field Descriptions:
Billing Name: The name to whom property tax bills are mailed.  This name is not necessarily the "owner of record".  Please contact the Rock Island County Recorder's Office to obtain the "owner of record".
Township: Rock Island County is a township form of government consisting of 18 townships.  Most property is locally assessed by township assessors. The work of township and multi-township assessors is subject to supervision and revision by the chief county assessment officer. The chief county assessment officer is appointed by the county board. The chief county assessment officer must have a minimum of two years of relevant experience, pass a qualifying examination, and possess a professional appraisal designation.
Parcel: When used with the two-digit number representing the Township, the parcel number is used to identify the property.
PIN Number:

Also know as the "Property Index Numbering System", the permanent parcel numbering system is simply a description, by numerical reference, to land parcels on assessment maps. Any particular parcel of property in the county can be located by its respective Permanent Parcel Number. The connection between the maps and the individual property records requires that permanent numbers be assigned to all survey townships, sections, blocks, lots and tracts where taxable or exempt. The various parts of the property index number described above combine to form a ten-digit property identification number.

The component parts are always listed in the same sequence: The first two digits represent the Survey Township or Area; the third and fourth digits represent the section or sub area; the digits in the fifth through the seventh position represent the block number and the last three digits represent the lot or parcel number. (In city, village, or subdivided areas where blocks are divided into lots, each lot or parcel is given a three digit number starting with 001 in the northwest corner of the block. The remaining lots in the block are numbered successively in an easterly direction for blocks with the long axis east and west, and are numbered in a southerly direction for blocks with the long axis north and south)

Property Address: The physical address assigned to the property location. If the parcel is "land only", it may not have a property address.
Acres: Acreage of property. If acreage=0, this information is not available at this time.
Legal Description:

The property description reflected in recorded deeds.  In many cases, this is in an abbreviated format.  To obtain the full, unabbreviated legal description, please contact the Rock Island County Recorder's Office.

Zoning Classification: Represents the Zoning Classification as assigned by Rock Island County. Only zoning classifications for unincorporated Rock Island County and Hillsdale are maintained by the Zoning and Building Department.  For all other jurisdictions, please contact the listed office for any zoning classifications or requirements.
