I am a renter.

Context. When I moved in, that was all against the baseboards like one expects. Rather, the carpet was. As time as gone by this has sunk down. Tape measure for scale. So it's a good inch and a couple cm of sinking in sixteen months. I have no idea what that metal thing is. It looks like a big nail? I used a finger to show someone how far the "hole" went and felt something metal. When I grabbed a flashlight, I saw that. What is going on here?

Second photo is the bathroom floor in the lofted area. Pretty sure there's water below it. The area of the floor feels spongy. That's never good.

Edit: Landlord is basically saying "nothing is wrong. We'll have maintenance come take a look." I have been in touch with them. More than once. In January of last year my foot went through the floor downstairs. (I was not injured.)

Edit 2: I began this thread because a friend of mine who is in construction was visiting and said "You have a big problem in here." There were a lot of things he pointed out that I just figured was "old apartment and landlord special paint slap." I had no clue.

Thank you all for the help, thoughtful comments, and the funny comments too. Laughing at a time like this is good. I have several phone calls to make first thing in the morning. More to add to my files too. Thank you again!

I'm a renter who noticed some soft spots on my bathroom floor (along with several other issues), which is in a lofted area. Below that is my HVAC closet. And sometimes things smell a bit funny in the bathroom. Pictured are three things that I'm not sure of, but they don't look great.

First photo is the ceiling of the HVAC closet and that's the bathroom above. In part. The bedroom is also there. I have no clue what's going on there or why there's a hole. Second photo is what looks like water on the walls there? I felt it and it didn't feel wet or anything. Third photo is the other side of the wall. The paper coming down and tape wasn't like that when I moved in.

Edit: If your answer is "call your landlord", I appreciate you. However, I've been in touch with the landlord about a myriad of issues. At this point, I'm outsourcing to see what exactly is going on and how bad it may be. Rather, do I call code enforcement or a Lawyer?
