That said, I’m -1 on HOAs. I’ve heard far too many complaints and too few people happy with them to deal with one.
A couple months ago a coyote decided to poop on my front door. Obviously, it was sending a message, but I'm not sure what it was.
Probably didn't like my HackerNews posts!
Certain types of invasive plans are noxious, outright poisonous, encourage hay fever, or just spread so fast that they can end up destroying neighbor's yards as well.
Plants don't obey property lines.
Edit: Unkempt yards can also be breeding ground for pests. From mosquitoes in still water to hoards of rats. Most people don't want to put up with those styles of annoyances that are trivially avoidable if everyone in the area cares just a little.
Rats come from having edible garbage available and fruit trees dropping fruit.
The most annoying things about neighbors are dogs that bark all day, and the leafblowers and lawnmowers.
Do you not encounter leaf blowers and lawn mowers in a HOA community? I would have expected it to be much worse because there would be maintenance crews doing it for every house in the area vs maybe a few houses on a ~20 house block.
If you have a plan for reforming the local judiciary to be so effective that HOAs are no longer necessary I am all ears, but I have not heard any proposals for doing that.
You know weeds are only weeds if you don't want them, right? Everywhere else they're just wild plants.
