I understand that, but if they don't enforce all the rules, what stops somebody from suing that they were fined for not mowing their yard (maybe they were too sick) or for that broken down car sitting in the street in front of their house (maybe they didn't have the money to fix it AND feed their family).
I agree that it sucks, but we have lots of those "all adult" communities around here and I guess I'm just surprised that they even tried to keep her there all these years. The problem is that if they allow her to stay there, then what about the next family? Pretty soon, there will be kids all over the place and that will change the "niche" of the community.
