Illinois Landlord Tenant Laws

  • Warranty of Habitability – Illinois landlords can only rent out habitable property, which means providing certain features essential to basic health and safety. This includes things like heat, plumbing, electricity, and sound structural elements. Landlords must repair any issues within 14 days after proper notice from the tenant. Failure to repair lets a tenant repair and deduct from the rent, or report the landlord to housing authorities. Tenants in Illinois can’t easily terminate their leases early or withhold rent.
  • Evictions – Illinois landlords may evict for rent default, lease violations, or illegal acts, among other things. Before filing eviction, landlords must serve tenants with prior notice to pay or quit, depending on the eviction type. This means most evictions in Illinois take a matter of weeks.
  • Security Deposits – Illinois does not set a maximum cap on the amount of a security deposit. Upon lease termination, a landlord has 30 days to return a security deposit, or 45 days to return any unused portion if making deductions.
  • Lease Termination – Illinois allows tenants to terminate a month-to-month lease with 30 days of advance notice. A fixed-term lease can’t be terminated early without active military duty, landlord harassment, uninhabitable property, or domestic abuse.
  • Rent Increases and Fees – Illinois landlords can raise rent by any amount, whenever they want, with no particular requirements for justification or advance notice. Late fees in Illinois must be “reasonable.” The state does not regulate returned check fees.
  • Landlord Entry – Illinois landlords may enter rental property for purposes reasonably related to the tenancy, such as maintenance and inspections. The state does not specify entry requirements, which means that a landlord can enter at reasonable times of day using reasonable advance notice (customarily at least 24 hours), unless the lease agrees otherwise. Entry requirements are temporarily suspended in emergency situations.
  • Settling Legal Disputes – Illinois allows its small claims courts to hear landlord-tenant disputes, as long as the amount in controversy is under $10,000.
