Usually these tiny homes are kosher to put in trailer parks. I think it is stupid that you can't place one on property you own in a city. (as long as you hook it to sewer and such)
But the property laws were written in the 40s and 50s with lots of input from the builders and insurance companies. See they want bigger houses so they can make more moola!
I’m sure there are some who are renting spacing in a trailer park, but the stories I’ve read and seen on tv show the greenies wanting to live free somewhere - without the rules- so one was parked in a back yard for awhile, another was out on some land (I have no idea where or who owned it) but it had no utilities so no sewer hookup. I assume they could pay to dump somewhere, but if they are biking it I doubt they would be hauling a heavy tank someplace.
