How Chicago regulates short-term rentals: the rules that apply, their sources, and pending changes.

- Whole-home non-owner-occupied STR permitted by-right in buildings of 5+ units
- Primary-residence-only for single-family homes and 2-4-unit buildings
- Per-building limit of the lesser of one-quarter of units or 6 rental units in 5+ unit buildings (per-building limit, not a citywide quota)
- Restricted Residential Zone precinct opt-out (targeted, not a citywide exclusion)
- Shared-housing/hotel accommodations surcharge collected on STR stays
Based on: Chicago Municipal Code Ch. 4-14 (Shared Housing Units), Ch. 4-13 (Short-Term Residential Rental Intermediaries), Ch.
Summary of the rule
City of Chicago Shared Housing Registration — Common Eligibility Criteria (BACP), per-building rules: 'SINGLE FAMILY HOME — Unit must be primary residence. Maximum 1 active rental. BUILDING WITH 2-4 UNITS — Unit must be primary residence. Maximum 1 active rental. BUILDING WITH 5+ UNITS — Unit does not need to be primary residence. Maximum of one-quarter of total number of dwelling units or 6 rental units, whichever is less.' Because whole-home non-owner-occupied STR survives (in 5+ unit buildings) under a citywide registration regime with no residential-zone exclusion, the operative device is a non-foreclosing per-building cap — Regulated, not Restrictive.

A city permit is not the whole picture — HOA, condominium, deed, or lease rules may be stricter.
