While we're waiting for an official inspection, I wanted to get some Internet experts' opinions.
I live in the 3rd-floor apartment of a building with two other units below me, all with virtually the same layout. Our living room floor is quite bouncy, so that we can see and feel it move a lot when our child or dog walks by, let alone an adult.
The ceiling of the 2nd-floor living room is visibly sagging and cracking, and moves when the floor upstairs is bouncing. It's pretty scary to see it from below.
Every other floor is solid, including the 2nd and 1st floor living rooms. The 1st floor living room ceiling is flat and free of cracks. This leads me to believe that there is a potentially serious problem with our floor, specifically.
Through all of this the landlord says this is totally normal and expected in an old building. I would agree if it were not completely inconsistent between the 1st, 2nd, and 3rd floors.
Am I reasonably concerned here?
