The Supervisor of Assessments’ Office is responsible for maintaining ownership records on all property located in the county. This is accomplished through reviewing documents recorded in the office of the Livingston County Recorder of Deeds to determine if a property is transferred, partitioned, annexed or detached.

If a property is transferred, the tax rolls are updated to reflect the new owner and billing address. The mapping company is notified of any partitioned property to create new parcel numbers to correspond with the new legal description(s). Any annexed or detached parcels must be recorded so that tax rolls can be updated to reflect changes in parcel numbers, legal descriptions, taxing districts, exemptions, and billing addresses.

The Supervisor of Assessments compiles all sales data on properties, which is sent to the State of Illinois Department of Revenue as well as local assessing officials. By State law, the local assessing officials are to assess residential, commercial and industrial properties at 33 1/3% of its market value as of January 1 of the assessment year.

Farmland assessments are based on the soil’s ability to produce a crop. These assessed values are certified by the State Technical Advisory Committee each year. Farm buildings are assessed according to contribution to the farm.

Shelly Renken assumed the position December 22, 2015, and was re-appointed for the term commencing December 22, 2019, and ending December 23, 2023. The Supervisor of Assessments is assisted by four full-time deputies. Nine assessors, two township assessors and seven multi-township assessors, are elected by the people for four-year terms.

In order for the county to be reimbursed one-half of the Supervisor’s salary by the State, the law requires that the residential, commercial, and industrial property must be assessed between 31 1/3% and 35 1/3% level of assessments on average.
