County Administration Building to Limit Visitor Access

WOODSTOCK, Ill. – In an effort to prevent the spread of coronavirus, visitors to the McHenry County Administration Building at 667 Ware Road will be limited to the front lobby, effective Wednesday, March 18.  Visitors will be asked to remain in the lobby while an employee is brought down to the lobby to work with them. This step is being taken to protect county employees as well as the public.  We appreciate your patience and understanding as we all work together to deal with this unprecedented situation.  Many county functions, such as permit applications, can be done online by visiting our website at www.mchenrycountyil.gov. Also, to further promote social distancing, we encourage people to call or email the relevant department with questions before deciding whether to travel to the Administration Building.  For more information on coronavirus, visit the Department of Health website at www.mcdh.info. You also can follow the Department of Health and McHenry County on Facebook and Twitter to receive the latest updates regarding county services.
