There's one in Muenster which costs the users nothing, actually! No electric, but sewage.
I actually moved away from such an illegal site in colorado many years ago, just before the city closed it down. They ignored it until someone complained, then they "had to" act. The owner was actually a german. Very expensive town, it was a nice little oasis for us wagen wohners.
It cost the poor guy 50,000 in legal expenses too, sadly.
Wow, that is horrible! Here oftentimes it is as you describe above: before someone complains, noone cares. but if they do, the city officiuals have "Zugzwang". I had to learn the hard ways as we run a creative arts studio in the city and we also held concerts there. the city itself kept renting our space for meetings.
one day someone complained about the noise and inquired if we had a betriebserlaubnis for events.
then the baumamt ppl came to inspect: no emergency exit. that killed the concert venue.
about our TH i called the city (i learned my lesson) and asked. they basically said: as long as it is on wheels (mobile) i can do whatever i want, especially since i onw the property. but i may NOT list it as a permanent residence. with postal address and such.
which i dont anyways. i have another address.
it is hard, though. i dont think many ppl dare to to this.
then the office later on said they arent even in charge to making decisions, it was jurisdiction of the environmental office.
so i called them and they were completely overwhelmed with the foreign concept of a tiny house and said, they's get back to me.
which they never did.
in our area are a few "Hippie-ish" communes.
they have Bauwagen, Little houses, treehouses, Campervans, etc. and the city knows of them and doesnt bother them. one guy has been out there for 14 years.
