Illinois Security Deposit After Move-Out: 30-Day Damage Statement, 45-Day Return & Normal Wear in 2026

The short answer

Illinois' Security Deposit Return Act separates the damage-accounting deadline from the full-return rule. When a landlord wants to withhold security as reimbursement for property damage, 765 ILCS 710/1 generally requires an itemized damage statement with estimated or actual repair or replacement costs and the required receipts within 30 days of the later of the date the tenant vacated or the date the tenant's right of possession ended.

If no statement and receipts are furnished as the Act requires, the statute says the landlord must return the security deposit in full within 45 days of the date the tenant vacated. Those are different statutory clocks, so a renter or landlord should document both the physical move-out date and the date the legal right of possession ended.

The 30-day damage statement uses the later of two dates

Public Act 103-0224 amended Section 1 effective January 1, 2024. The current damage-accounting rule measures the 30-day period from the later of the date the tenant vacated the leased premises or the date the tenant's right of possession ended.

That distinction can matter when a tenant moves out before the scheduled lease end. Do not assume that turning in keys early always shortens the landlord's 30-day damage-accounting period. Keep the signed lease, any termination agreement, key-return record and communications about when possession legally ended.

A lease clause for painting, carpet cleaning or repairs is not a blank check

Illinois law allows a written lease to specify a cost for cleaning, repair or replacement of a component in certain circumstances, but the statute also limits those lease-specified costs. They must be for damage beyond normal wear and tear and must be reasonable to restore the premises to the same condition as when the lease began.

When a landlord relies on a lease-listed amount, the itemized statement must reference the dollar amount associated with the specific component or amenity and include a copy of the applicable portion of the lease. That means a lease provision about painting or carpet work should be analyzed together with the actual move-out condition, normal wear and tear, the reasonableness of the amount and the required accounting rather than treated as an automatic deduction merely because the clause exists.

A closing credit in a property sale is not itself the security-deposit accounting

A seller and buyer may allocate money between themselves at a real-estate closing for many reasons. The Security Deposit Return Act, however, focuses a damage-based withholding on damage allegedly caused to the leased premises, the estimated or actual repair or replacement cost, and the required supporting documentation.

For that reason, the fact that a seller gave a buyer a closing credit does not by itself establish the amount that may lawfully be deducted from a former tenant's security deposit. If a landlord points to a closing credit, ask for the statutory itemized statement and the underlying repair or replacement support showing how the claimed tenant-caused damage produced the deduction. This guide does not decide whether a particular closing adjustment creates a separate contractual claim between other parties.

If no compliant damage statement and receipts are furnished, the Act uses a 45-day full-return rule

Section 1 states that if the required statement and receipts or copies are not furnished to the tenant as required, the landlord must return the security deposit in full within 45 days of the date the tenant vacated the premises. The statute permits delivery in person or by postmarked mail to the tenant's last known address or another address the tenant provided.

The Act also says a landlord is not liable for damages or penalties resulting from the tenant's failure to provide a mailing address or email address. A tenant should therefore give a clear forwarding address in writing and preserve proof that it was provided.

Estimates do not eliminate the receipt requirement

The Act allows the initial itemized statement to use estimated or actual repair or replacement costs. When an estimated cost is used, the landlord generally must later furnish the paid receipts or copies within 30 days after the statement showing the estimated cost was furnished.

If receipts cannot be produced through no fault of the landlord, subsection (b) provides a separate process requiring an itemized cost list, other evidence of cost and a verified statement explaining specifically why the receipts cannot be produced and confirming that the other cost evidence has been provided.

The double-deposit remedy is not automatic

Section 1(c) contains a remedy tied to a circuit-court finding. It applies when the court finds that the landlord refused to supply the required itemized statement or supplied it in bad faith and also failed or refused to return the amount of the security deposit due within the statutory time limits.

When those statutory findings are made, the provision states that the landlord is liable for twice the amount of the security deposit due, plus court costs and reasonable attorney's fees. That remedy is not automatic merely because a deadline, deduction or lease clause is disputed; the statute expressly conditions it on the required court findings.

Illinois removed the old five-unit threshold

Older summaries of the Illinois Security Deposit Return Act may still say it applies only to residential properties containing five or more units. Public Act 103-0224 removed that limiting phrase from Section 1 effective January 1, 2024.

Current disputes should therefore be checked against the current statute rather than an older web page that still carries the former unit-count language. Local ordinances can impose additional or different protections, so the property's municipality should also be verified.

What to preserve before disputing a deduction

Keep the lease and every addendum, especially any clause listing painting, cleaning, carpet or repair amounts; move-in and move-out photos; condition reports; maintenance requests; the date you physically vacated; the date your right of possession ended; proof of key return; the forwarding address; every itemized statement; receipts or estimates; refund records; envelopes and postmarks; and messages discussing the claimed deduction.

If the landlord refers to a sale or a credit given to a buyer, preserve that communication too, but separate the closing transaction from the statutory security-deposit analysis. The central questions remain what tenant-caused damage is actually claimed, whether it exceeds normal wear and tear, whether the amount is reasonable and whether the statutory accounting requirements were met.
