I’ve seen some insane restrictions on what you can and can’t do in apartments.

Like in my apartment I’m only allowed to put an AC in 1 window of my apartment (the furthest from the bedrooms BTW), it can’t be anything other than a portable AC, and any gap around the hose needs to be clear (glass, polycarbonate, acrylic, etc.) yes even the window insert that comes with the AC has to be clear. When I moved in I thought the insert around the hose that came with it not being clear would be fine, it in fact was not. It also has power draw restrictions so I can only basically get the smallest kinds on the market.

I’m also required to have all windows and doors closed and locked when nobody is at home. Yes that means I have to pull my AC hose out of my window when I’m not home. I figured that out again the first year I lived in my apartment. (they rang my bell when I wasn’t home, then sent me a certified letter informing me I had 72 hours to fix the problem or they would serve me notice to vacate.)

Yes every summer it easily clears 90F (32C) inside and sometimes even breaks 100F (37C). And due to being an upstairs apartment that means the heat stays almost in it’s entirety overnight.
