Run the Chicago verdict on your facts
| What counts as a short-term rental | Shared housing means renting a dwelling unit, or part of one, for under 32 consecutive days. Chicago registers the unit (not just the host) and bans some buildings outright. |
|---|---|
| Permit / license | Shared Housing Unit Registration (operator license for hosts with multiple units) — issued by Chicago BACP (Business Affairs and Consumer Protection) |
| Fee | $250 per year unit registration; a shared-housing operator license is $500 |
| Renewal | Annual renewal |
| Primary-residence rule | For houses and 2–4 unit buildings, the unit must be the host's primary residence. Larger buildings follow the building-cap rules instead. |
| Whole-home rental | Hosted and whole-home stays are both possible once registered — subject to the Prohibited Buildings List, Restricted Residential Zones, and building caps (25% of units or 6 units in buildings of 5+). |
| Night cap | — |
| Guests / occupancy | Per the ordinance's occupancy rules |
| Minimum stay | 2-night minimum stay |
| Zoning | Two lists decide many Chicago verdicts before any host fact does: the Prohibited Buildings List (condo and rental buildings that opted out) and Restricted Residential Zones. |
| Density / scarcity | No density cap found in the current rules |
| Fines | $1,500–$10,000 per offense — and each day of violation is a separate offense |
| Taxes | Chicago hotel accommodations tax and the shared-housing surcharge apply; registration includes the tax setup. |
| Platform duties | Platforms process registrations and must not list unregistered units. |
| State layer | No state preemption. Chicago runs a full shared-housing ordinance; most suburbs write their own rules or bans. |
What trips hosts in Chicago
- In a building of 5+ units, only 25% of units (or 6, whichever is less) may be shared housing — your neighbor's registration can block yours.
- Renters: Chicago registration does not override a lease, and many Chicago leases are enforced on exactly this point.
The private layer still applies
These are the city's rules. Your HOA, condo board, lease or mortgage can say no on top of them — that layer is printed as a warning in the checker, never merged into the city's verdict.
