Summary
Unincorporated Cook County does not have a dedicated short-term rental licensing or insurance ordinance. Short-term rentals in unincorporated areas fall under the Residential Rental License program (Ch. 102-180 through 102-197) for buildings with 4+ units. Illinois state law requires hosts to collect and remit hotel occupancy taxes.
Cook County Residential Rental License Ordinance — On June 29th 2016, the Cook County Board of Commissioners passed the Rental Dwelling Ordinance which requires the owners of the multi-unit buildings of four (4) or more units to obtain a Residential Rental License effective January 1st 2017. The Cook County Board of Commissioners has deemed it necessary to establish a Residential Rental License for Unincorporated Cook County in order to effectively protect the public health, general welfare and safety of its residents. The Cook County Department of Building and Zoning aims to ensure residential rental units comply with the minimum standards of habitation, occupancy, construction maintenance, proper use, appearance and with the building and zoning codes adopted by Cook County. A Residential Rental License is required to be obtained by the owner of each rental dwelling unit (including condominium units) in buildings of four (4) or more units. An interior inspection of the residential rental unit will also be required. A complete copy of the Residential Rental License Ordinance can be found under ORDINANCES AND CODES (Chapters 102-180 through 102-197 Fees Sec 32.1 CH 102-155.8).
Full Breakdown
Cook County has not enacted a comprehensive short-term rental (Airbnb/VRBO) licensing ordinance for unincorporated areas comparable to those in Chicago or other municipalities. The Cook County Residential Rental License Ordinance, effective January 1, 2017, requires owners of multi-unit residential buildings (4+ units) in unincorporated areas to obtain a Residential Rental License from the Department of Building and Zoning. This includes interior inspections. While this ordinance does not specifically target short-term rentals, it establishes baseline requirements for rental properties. Short-term rental operators in unincorporated Cook County must comply with the Illinois Hotel Operators Occupation Tax Act (35 ILCS 145) and may owe Cook County hotel accommodation taxes. Standard homeowners insurance typically does not cover short-term rental activity; operators are advised to carry commercial liability insurance or a short-term rental endorsement. Many hosting platforms provide limited host protection insurance.
Violations & Fines
Operating a rental in a 4+ unit building without a Residential Rental License: penalties under Ch. 102-180 through 102-197. Tax non-compliance: penalties under 35 ILCS 145.
