Illinois Rules - Eviction, Security Deposit, etc.

[Vishal P.]

For investors with experience and knowledge for Illinois (specifically DuPage county) rules, I am looking for some insight on the below:

- Can security deposit be forfeited if lease is broken (either by not paying rent or any other infractions of lease contract)? Are security deposit rules regulated by state or are they lease/contract driven?

- Can you accept partial payment after serving 5 day notice? I have heard it's acceptable to take partial payment, you simply have to issue another 5 day notice with updated balance due.

- Is Landlord responsible for lost checks dropped into rent drop box within the building? We currently have rent drop boxes installed in our buildings and I am wondering if someone were to try to break them open and steal something, is the landlord responsible for any successful stolen money. Someone were to successfully cash a check somewhere, etc.

- Does anyone know any Illinois specific resources/websites for rules/laws for landlords that I can review?

Thanks in advance!
