Can a Illinois landlord give a 30-day notice to terminate without cause?
For a month-to-month tenancy, yes in most states by serving the statutory advance notice (5 days for pay-or-quit under 735 ILCS 5/9-209, 10 days for violations under 5/9-210). For a fixed-term lease, no: the landlord cannot terminate mid-term without cause. Illinois tenant-protective laws may restrict no-fault termination on long tenancies (e.g. California AB 1482 just-cause rules after 12 months, New York Good Cause Eviction). Local rent-control ordinances can add further just-cause requirements. If the unit is in a covered just-cause jurisdiction, the landlord must specify a qualifying reason on the notice.

This is an informational answer based on Illinois eviction statute as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Illinois-licensed attorney.
