Our office is doing all we can to ensure our assessments reflect any effects of COVID-19. South Suburban reassessments scheduled for this year will be adjusted to reflect estimated effects of this pandemic on property values. North Suburban and Chicago assessed values will be examined this year to determine what adjustments need to be made due to the economic effects of COVID-19.
