The Joliet Township Assessor’s Office in an effort to coordinate with the Center for Disease Control and Prevention by minimizing contact to mitigate the spread of COVID-19 coronavirus is reducing its operation to phone and email contact only. We will continue to answer taxpayer calls and emails, but will not be open for in-person public business until further notice.
