so what is the real big deal with all of this.  its just a bunch of nosey neighbors or jealous neighbors.  I can see if there is criminal activity going on like drug dealing, meth labs, abuse, prostitution etc etc, but i don't see why a homeowner can't rent out a room or part of their house to short term renters.  One day they gonna pass a law that you can only flush your toilet 2x a day and these nosey neighbors will be listening to the flushes. LOL
Mind your own business folks, unless they are doing criminal behavior.
