Late/Returned Fees <p>llinois law does allow landlords to impose late fees for overdue rent, provided the fees are reasonable and clearly specified in the lease.

Additionally, for returned checks, Illinois law limits the fee to $25.&nbsp;</p>
Mold Disclosure <p>Illinois law doesn't require landlords to disclose mold presence. Nonetheless, maintaining the property to prevent mold growth falls under the landlord's duty to provide habitable premises.</p>
Non-Refundable Fees <p>Landlords must clearly disclose any non-refundable fees in the lease agreement to enforce them</p>
Smoking <p>Landlords in Illinois can set their own smoking policies. It's advisable to include clear terms regarding smoking in the lease to ensure tenant compliance.</p>
Security Deposit Disclosure <p>Under the Illinois Security Deposit Return Act, landlords must return the security deposit within 45 days after the tenant vacates the premises, provided there are no damages or unpaid rent. If deductions are made, an itemized statement of damages and receipts must be provided within 30 days. Additionally, for buildings with 25 or more units, landlords are required to pay interest on security deposits held for more than six months.</p>
Flood Hazard Disclosure <p>As of January 1, 2025, Illinois law requires landlords to notify potential tenants if a property is in a FEMA-designated flood zone. This disclosure helps tenants make informed decisions regarding potential flood risks.</p>
Radon Disclosure <p>Under the Illinois Radon Awareness Act, landlords must inform tenants if radon tests have revealed elevated levels of radon in the dwelling. This disclosure is vital for tenant safety, given the potential health hazards of radon exposure.</p>
