Illinois Landlord Tenant Laws

  • Warranty of Habitability – Illinois state law does not describe the specific obligations of landlords when it comes to habitability, but Illinois landlords must remain compliant with housing, building, health codes or by community standards. If this standard degrades due to an amenity in poor repair, the Illinois landlord must perform the repair within 14 days. If not, the effected tenant may deduct a sum of the repair cost (not exceeding $500 or 1/2 month’s rent) from a following rent payment.
  • Evictions – In Illinois, landlords may evict tenants for a number of reasons including, but not limited to failure to pay rent, a violation of a leasing term, or committing an illegal act. Landlords must provide tenants with prior notice to pay or quit, depending on the type of eviction. In most cases, though, an eviction in Illinois takes longer than a couple weeks.
  • Security Deposits – Illinois does not maintain a limit with regards to tenant security deposits. However, the state does require landlords to return any collected deposits within 30 days (no deductions) or 45 days (with deductions).
  • Lease Termination – Terminating a month-to-month lease in Illinois requires 30 days of notice to be provided prior to moveout. To legally break a lease early otherwise, a tenant must apply for early termination on the grounds of active military duty, statutory uninhabitability, or domestic violence.
  • Rent Increases & Fees – Illinois landlords are not required to justify their rent increases, nor are they limited when it comes to the value of these increases. Late fees in Illinois must be reasonable and there is no state statute on bounced check fees.
  • Landlord Entry – Illinois as a whole does not establish a minimum landlord entry standard. However, Chicago does require all landlords there to provide 2 days of notice prior to entry. Any standards established in this manner are usually exempt in emergency situations.
  • Settling Legal Disputes – In Illinois, landlords and tenants may file a variety of claims with the state’s small claims court. However, these claims are limited in value to under $10,000 only.
