Illinois renter rights, in plain English
Illinois rules vary between state law and stronger local ordinances (like Chicago's). Here's the plain-English statewide baseline plus what to watch for.
Security deposits
Illinois has no statewide deposit cap, but larger buildings must return deposits within 30–45 days and, in many cases, pay interest on deposits held for over six months. Chicago's ordinance adds stricter rules and penalties.
Notice periods & entry
Statewide, reasonable notice before entry is expected; local ordinances often specify 48 hours. Month-to-month tenancies typically require 30 days' notice to end.
Late fees
Under Illinois law, late fees are limited for many residential tenancies, commonly capped (for example, $20 or a modest percentage tiered by rent amount). Local rules may apply.
Clauses that don't hold up
- Waiving deposit-interest requirements where they apply.
- Confession-of-judgment clauses in residential leases.
- Waiving the warranty of habitability.
- Excessive late fees above the statutory limits.
