A security deposit demand letter is a communication from a landlord to a tenant requesting the immediate payment of an outstanding security deposit in Illinois. This letter serves as a formal notice stating the tenant's obligation to return the full security deposit as required by Illinois state laws and the terms of their lease agreement. In some cases, a security deposit demand letter may also be sent when a landlord seeks compensation for damages or unpaid rent. When a security deposit demand letter is issued without payment, it signifies that the tenant has failed to fulfill their legal and contractual obligations regarding the return of the security deposit within the specified time frame, typically within 30 days after the expiration of the lease agreement.
