How to Dispute Unfair Carpet, Paint & Cleaning Deductions in Illinois
Even when a Illinois landlord mails an itemized list within 30 days, they cannot charge you for normal wear and tear or bill you 100% of the replacement cost for an aged asset that has already exhausted most of its useful life.
1. Useful-Life Proration
Standard apartment carpet depreciates over 5 years (60 months). If carpet was 4 years old at move-out, the maximum recoverable value is 20% — never a full replacement bill.
2. Statutory Demand Notice
Send a written demand via Certified Mail citing 765 ILCS 710/1 (Security Deposit Return Act) and giving a firm 7-to-10 business day deadline before filing in Illinois Small Claims Court.
