21 days, with interest

Within 21 days after the tenancy ends, or 15 days after receiving the tenant's forwarding address in writing if that is later, deliver the full deposit with interest, or the balance after damages with a written statement itemizing the nature and amount of the damages. The time was 30 days before Public Act 23-207 shortened it to 21.

The forwarding address

When the tenancy ends, the tenant may give a forwarding address in writing, and the deposit and statement go to that address.

What may be deducted

Deductions are limited to damages the landlord suffered because the tenant failed to comply with the tenant's obligations.

The penalty

A landlord who breaks these rules owes twice the security deposit; if the only failure is the interest, ten dollars or twice the interest, whichever is greater. A tenant can sue to reclaim any part of the deposit due, and either side may still recover other damages.

Common mistakes

Using the old 30 days instead of 21.
Forgetting the interest on the deposit.
Mailing to the old unit when the tenant gave a forwarding address.
Deducting for anything other than damage from the tenant's failure to meet their obligations.
