What can a Illinois landlord deduct from the security deposit?
Illinois generally allows deductions for: unpaid rent, damage beyond normal wear and tear, cleaning beyond normal, and costs to comply with the lease (e.g. carpet cleaning if required). NOT allowed: normal wear and tear (scuffs, minor nail holes, fading), repainting because paint is old, pre-existing damage (unless documented at move-in), and upgrades. Bad-faith deductions can trigger penalties: Up to 2x the deposit amount if the landlord acts in bad faith under 765 ILCS 710.

This is an informational answer based on 765 ILCS 710 as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Illinois-licensed attorney.
