I am an American and I am currently residing in America. And where I live and everywhere near me, there's no way they'd allow you to park on your lawn, etc. We have a democratically elected council which is empowered to create town ordinances and things like this fall under these ordinances.

For instance, we don't allow "trash and debris" and plant life can't be "overgrown" and your property must be kept clean and free of garbage". Things can't be "unsightly" or in disrepair. There's a bunch of ordinances that apply to these things.

If you disagree with it you can:

1) Plea to the council and/or campaign to elect someone who will change the ordinances

2) Move
