No cap (Illinois bars them), but the Chicago RLTO sets the notice ladder tenants actually win on: 30 days under six months in the home, 60 days from six months to three years, 90 days beyond three years, for covered units.
Illinois bars rent control statewide, Chicago included. What Chicago tenants hold is the RLTO (Residential Landlord and Tenant Ordinance), and inside it a notice ladder set by how long you have lived in the home: 30 days under six months, 60 days from six months to three years, 90 days beyond three years for covered units. Owner-occupied buildings of six or fewer units and a few other categories sit outside the RLTO — coverage is the first question, as it is in California.
A short-notice increase in Chicago is the classic winnable fight: the amount can be anything, the calendar cannot.
