The rules that apply in Illinois
Illinois has no statewide cap on lot-rent increases, and a 1997 law preempts any city — Chicago included — from setting one locally (50 ILCS 825). Every increase needs 90 days' written notice (765 ILCS 745/6). Illinois also has a mechanism most states don't: a resident who can show the new rent would exceed 45% of household income may defer paying the increase for up to a year while listing the home for sale, provided they stay current on the old rent (765 ILCS 745/6.4).
