Full Breakdown
Under Municipal Code of Chicago Section 17-9-0201-F(17), dwelling units inside coach houses (detached ADUs) lawfully established after May 1, 2021 cannot be rented, leased, or otherwise made available for compensation for transient occupancy, Chicago's legal term for stays under 32 days, as defined in Section 4-6-290, to anyone outside the unit owner's or tenant's own household. Long-term rentals to a tenant and that tenant's household remain allowed; it is the Airbnb-style short-term booking that is prohibited. The Department of Planning and Development, Department of Housing, Department of Buildings, and Department of Business Affairs and Consumer Protection can each enforce the ban. Coach houses built before May 1, 2021 are not subject to this restriction.
Violations & Fines
Fine of $1,500 to $3,000 per offense; each day the unit is listed or rented in violation counts as a separate offense.
