To account for the COVID-19 pandemic’s impact on real estate values throughout Cook County’s neighborhoods and communities, the Cook County Assessor determined that it is appropriate to apply COVID-19 Adjustments to property values in 2020, where applicable. The extent of these adjustments will depend on each property’s use, type, and location.
Changes in the economy and local unemployment were used to calculate adjustments in neighborhoods of the South and West suburbs.
