Are you a tenant in a complex owned by a corporation or is it some guy who owns the building? He could be a "corporation", but that would more or less be on paper to protect his assets. Hopefully you're a tenant in a building owned by a larger corporation. It'll be easier to get what you need/want out of them.
The apartment I moved into once had no flashing installed. The trees surrounding my apartment created shade all of the time. There was zero direct light into the apartment. Evidently there was a broken sprinkler that no one detected that gushed water right at the foundation of the master bedroom. The floor was constantly cold and damp. I was told it was because it was always shady in the apartment. I pulled out a few stacks of books from under the bed one day and they were riddled with mold. They came in and did the normal cleaning, air drying with large fans, etc etc. I was out in 5 days as I informed them of my asthma and had to live in an environment free of mold. Like a human.
I had a new apartment and moving expenses were reimbursed within about 3 weeks. The apartment was owned by a large corporation. It was the manager who was a dill weed.
I hope you get this resolved.
Oh ****...I'm drinking water. That's it. Just plain water.
