Chicago FAQ
Can my landlord charge a flat utility fee?
Only if disclosed in writing before signing and not exceeding actual building cost. Tenants may request the master bill at any time under MCC 5-12-100.
What about valet trash or amenity fees?
Lease pass-throughs must be itemized in writing. Surprise charges added mid-lease are unenforceable and may support an RLTO retaliation or good-faith claim.
Tinley Park FAQ
Can my landlord add a junk fee mid-lease?
No. Any charge not disclosed in writing before lease signing is unenforceable under RTLO. The tenant may refuse and recover any amounts already paid plus attorney fees.
Are utility submetering charges legal?
Yes if disclosed and limited to actual cost. Markups, administrative surcharges beyond reasonable billing cost, or undisclosed methods violate RTLO and are recoverable by the tenant.
