My HOA forbids people on the second story from having a BBQ. I did not know this when I moved in, and I've since had to get rid of my BBQ, which was a HUGE hobby of mine. Once I'm out of here, I'll never live anywhere with a HoA again.
Plus, they have crazy rules about how many and what kind of pets you can have. I _never_ take my snakes outside unless they're well concealed, and I'm careful to keep my cats out of the windows.
