Years ago there was an American guy over in the UK visiting the company I worked for at the time. As we were driving along we went past a load of Allotments and there were all the little sheds and the typical older people working on their plots.
He looked puzzled and asked "what are those?"
We told him that was an "Elders Farm" where old people were sent once they reached a certain age if they couldn't afford rent and they were given a small hut to live in and could grow their own food to try and survive.
He was very horrified. LOL
It's not unusual in North America to have some local rules in how your property looks and what is and isn't allowed in your yard, front and back. If we let our front grass grow too long someone would come and cut it and give us the bill. It's not like the UK where you can park a rusty car on your front lawn.
