How often can rent be raised in Illinois?

Quick answer

Illinois does not limit how often rent can be raised at the state level, but each increase still needs 30 days' written notice and must not violate a fixed-term lease.

Step-by-step answer

  1. Step 1

    Fixed-term leases

    While you're inside a fixed-term lease in Illinois, the rent generally cannot change until the lease ends. That effectively limits increases to once per lease cycle.

  2. Step 2

    Month-to-month tenancies

    On a month-to-month tenancy, the landlord can propose a new rent whenever they give 30 days' written notice. Multiple increases in a short window can still be challenged as unreasonable or retaliatory.

Plain English recap

Illinois does not limit how often rent can be raised at the state level, but each increase still needs 30 days' written notice and must not violate a fixed-term lease.
