Illinois Landlord-Tenant Law Guide
Illinois landlord-tenant law provides substantial protections for tenants, particularly in Chicago where additional local ordinances apply. The state has clear requirements for security deposits, property maintenance, and eviction procedures.
Security Deposit
Limit: No statewide limit, but many municipalities have caps. Chicago limits deposits to 1.5-2 months' rent depending on unit type.
Return Period: 30-45 days depending on length of occupancy. Must include itemized statement for any deductions. Interest must be paid on deposits in some cities.
Rent Increases
No statewide requirement for month-to-month leases, but 30 days is customary. Chicago requires 30 days notice; some units under rent control need 60 days.
Entry Notice
No statewide requirement, but 24 hours notice is standard and required in many local ordinances including Chicago RLTO.
