Summary
Cook County's zoning ordinance does not require a short-term rental host to add parking spaces beyond what already serves the dwelling, true for both Supervised and Non-Supervised rentals in unincorporated Cook County, unless the existing parking is already non-conforming, or a Non-Supervised rental's special use permit imposes extra spaces case by case.
[Supervised, § 8.7.11.B.a.ii] ii.Parking. No additional parking is required unless the existing parking ancillary to the dwelling is non-conforming. In this case, the parking shall be improved to comply with the zoning ordinance. [Non-Supervised, § 8.7.11.B.b.ii] ii.Parking. No additional parking is required unless the existing parking ancillary to the dwelling is non-conforming. In this case, the parking shall be improved to comply with the zoning ordinance. Additional parking improvements may be required as a condition of special use approval on a case by case basis.
Full Breakdown
ii, covering Non-Supervised rentals (host absent), use identical baseline language: no additional parking is required for the short-term rental use itself. The only trigger for change is if the parking already ancillary to the dwelling is non-conforming under the zoning ordinance, in that case it must be brought up to the standards of Article 11, Off-Street Parking and Loading, regardless of the short-term rental. ii adds one more layer: the Department of Building and Zoning may require additional parking improvements as a condition of that special use approval, decided case by case rather than by a fixed formula.
Supervised rentals, needing only a home-based business occupancy rather than a special use, are not subject to that case-by-case add-on. The rule sits inside Appendix A, the Cook County Zoning Ordinance of 2001 (comprehensively re-adopted by Ord. No. 2 reaches only unincorporated Cook County and any incorporated town without its own zoning ordinance, not Chicago or the county's other incorporated municipalities.
Violations & Fines
Operating a short-term rental on a lot with already non-conforming parking that is never brought into compliance, or ignoring parking conditions imposed as part of a Non-Supervised rental's special use approval, is a zoning violation the Department of Building and Zoning can enforce through a compliance order, and, for Non-Supervised rentals, through revocation of the special use permit itself, since that permit is void if its conditions aren't met.
