[Peace of Mine]

You've already discovered the way to do it. Of course nobody would say a word about you building your daughter a playhouse! And who would know if you moved into it and rented out your main house? Why not live where you want to live?

Either ignore their silly rules or find ways around them. Don't apply for permits. If you do the work yourself, and why wouldn't you - it's the most satisfying, pleasurable step toward self-sufficiency that you could take - nobody will bother you. Been doing it for years. Never paid a fine yet.
