Tenant Left and Filed Buildings Claim

[John Casmon]

We had a tenant up and leave after not paying rent for two months. Subsequently, we just received a notice of violation with the Chicago Department of Buildings that list a handful of exterior items and mold in that same tenant's apartment (which they were not able to verify because the tenant wouldn't let them in). We're in the process of suing the tenant for the back rent and damage to the unit and I'm guessing she called the city to report the violations to claim unsafe living conditions or something. We're working on fixing the violations listed (crack in the lintel, broken window pane, loose deck board, etc), but how will/could this impact our case on the tenant? We have a PM firm that manages this building and to our knowledge mold was never reported or noticed until she vacated.  We have all repair orders from her on file and have fixed them all. Any tips on things to prepare for the buildings code hearing and then separately for our case against the tenant?
