OK. But then.
Per the reader:
I was in our apartment Wednesday afternoon when someone knocked. Our hallway is pitch black, so I wouldn't open the door. A guy on the other side had "paperwork" for me to "sign." It was a 30-day notice of termination of tenancy!
They also had a bunch of guys collected outside the previous morning with a dumpster to demolish and gut another apartment in the buiding. There is no light in the halls. It was impossible and completely unsafe ... and they didn't work, thankfully for them.
