I honestly don't know if I could say anything... this is hideous!
The only thing that comes to mind here is, "If it didn't kill you, it will make you stronger"! Maybe all these shenanigans will help you create rules that will help you in the long run. I'd probably get a lawyer to generate the ones that give you leverage within the structure of the law, and then enforce it. Rules like fire codes and how many people are legally entitled to be in the cottages. If it persists, maybe you can make friends with the local fire department to come be the a*holes? We had to do that when I lived in CA and our neighbors had a variety of extended family come let them live with them. It was a lot easier to have the fire marshal come out and threaten to take legal action.
Anyway, you're in my thoughts. Here's to having more Sun in your future!
