at least the owner seems like he's smart enough to know the correct procedure but man talk about a total bitch. I'm kinda tempted to put plywood up instead of drywall since the walls are bare and that would completely make sure that would ever happen no matter where they hang them.

Just gonna answer some questions that people have.
My boyfriend owns the apartment, it is in a co-op. We hired a licensed contractor to come in and do all of the work (complete gut renovation), and the contractor's insurance was approved by the co op before he could come in and do anything. We live in an older building that is entirely concrete, the walls are made of metal lath and plaster and no studs. Some (like this wall) were replaced by our contractor and are drywall. It IS possible to anchor heavy objects with certain anchor bolts, but obviously he did not use the right ones. He did not advise us to change the construction of the walls,we weren't even living in the apartment at the time of the renovation. Everything was finished about 5 months ago.
We're currently seeking legal advice before we move forward.
Oh, and yes, I'm physically fine, just minor cuts and bruises.
