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.
