Illinois Security Deposit Laws

Updated October 13, 2026 · 1 min read · 3 sources

Short answer

Illinois security deposit limit: no statewide limit (local ordinances may apply). The landlord must return the deposit, minus lawful deductions, within this deadline: 30 days if deductions are claimed with an itemized statement; 45 days if nothing is withheld. Landlords cannot deduct for normal wear and tear, and tenants can usually sue in small claims court if a deposit is wrongly withheld.

Deposit disputes are among the most common landlord-tenant problems. This page covers the Illinois rules in plain English.

What landlords can deduct

  • Unpaid rent
  • Damage beyond normal wear and tear
  • Cleaning to return the unit to move-in condition, where the law or lease allows it
  • Other charges the lease and state law permit

Normal wear and tear, such as minor scuffs, faded paint or carpet worn by ordinary use, generally cannot be deducted. Many states require landlords to give an itemized list of deductions with any remaining deposit.

How to protect your deposit

  1. Document the unit at move-in and move-out with dated photos; the rental move-in and move-out checklist helps.
  2. Give proper written notice before moving out and return all keys.
  3. Give the landlord a forwarding address in writing.
  4. If the deadline passes, send a written demand, then consider small claims court; see the Illinois small claims court limit.
