If the access to that panel is as bad as it looks, I would call the contractor and ask him some questions (my first impression is to give him the benefit of doubt). If he tells me on the phone (after I have arrived for the inspection, not before), that he was/is aware of this mess, I would tell him that I do not have proper access to make a thorough inspection, and that he would have to make the corrections for me to make this inspection.
I am fully aware that sometimes the EC will make an install and then all of that "junk" is installed after he made his installation. I can live with that. Then the building owner gets the violation.
