No statutory limit on the deposit amount (Illinois AG: 'there is no legal limit').

Interest required only for buildings/complexes of 25+ units and deposits held 6 months or longer; rate published annually by IDFPR (Security Deposit Interest Act, 765 ILCS 715). No interest under state law for buildings under 25 units.

The uploaded dataset lists a deposit-return period of 45 days. Review the cited rule for the applicable conditions and timing.

Illinois: Notices and tenancy endings

5-day written demand for rent for nonpayment (735 ILCS 5/9-209); paying within 5 days defeats termination. Lease-violation evictions use a 10-day notice.

30 days' written notice to terminate a month-to-month tenancy (735 ILCS 5/9-207); year-to-year 60 days; week-to-week 7 days.

Court listed in the supplied dataset: Circuit Court (Eviction Article, 735 ILCS 5 Art. IX).

No statewide residential rental license; imposed municipally in some cities (e.g., Chicago).

Illinois: Lease disclosures and receipts

Lead paint (federal, pre-1978)
