Issuing Notices for Multiple Violations

[Shannon Gauthier]

If you have tenants who are violating multiple sections of their lease, would it be better to send one all-encompassing notice to comply, or one notice for each individual violation?  

Also, does anyone send a notice off fee assessment, or do you simply make a phone call? I have a fee that has gone unpaid by the tenant for several months, but am unsure how to address it. They are becoming increasingly difficult to deal with, and we are pretty certain there will be an eviction in our future. We just want to make sure we have our ducks in a row, since we are new Landlords.

State of Illinois, DeKalb County, for anyone who might be familiar with those particular laws. We do not live in that state ourselves.
