How much notice does a landlord have to give before raising the rent in Illinois?
In Illinois, the notice a landlord must give before a rent increase depends on how long the tenant has lived there: Less than 6 months — 30 days; 6 to 36 months — 60 days; 36 months or more — 120 days. This is 735 ILCS 5/9-207, 9-209; Chicago RLTO § 5-12-130.
