Arlington Heights FAQ
Is the booking platform liable if my Cook County STR is unregistered?
Generally no. Cook County places legal liability on the host. Platforms may delist a unit under data-sharing agreements with the Department of Revenue but face limited statutory liability of their own under Ord. 19-5236.
Does Chicago's stricter posture reach into Cook suburbs?
No. Chicago's MCC 4-13 only governs Chicago listings. Cook County suburbs and unincorporated areas operate under Ord. 19-5236 or each suburb's own STR rules, not Chicago's platform-liability framework.
Chicago FAQ
Does Airbnb verify my Chicago registration before publishing?
Yes. Under MCC 4-14-270, platforms must check the registration number against the BACP database, display it on the listing, and remove any listing that lacks valid registration.
Who collects the Chicago Hotel Accommodations Tax?
Platforms remit the Hotel Accommodations Tax and Shared Housing Surcharge directly to the Chicago Department of Finance under MCC 4-14-270, sparing most hosts direct filing duties.
