That's what national laws and the city government do in Germany, and I presume a lot of the rest of the world. I live in a neighborhood where the average lot size is something around 250 square meters (2800 sq ft) for the single-family houses, and we're fine.
Someone is making racket after 10pm or before 7am, or at all on Sunday? If they won't quiet down after being asked nicely, or you can't reach them, call the city - that's against national law. Someone decides to park something too wide for the street or over a certain size and weight? Call the non-emergency number, and a very eager tow-truck driver will show up with a quickness you wish ADAC (German AAA) would. Something has been parked on the street and not moved within a certain period (that I don't know off the top of my head) - tell the city that there's an abandoned vehicle and they'll put a sticker on it alerting the owner that they have 48 hours to move it. If parking is really tight in a neighborhood, the city will create a parking permit zone if you and your neighbors campaign for it. Someone doesn't mow their yard by July (before that, it's for the sake of wildlife) or won't get their tree that is growing over your fence trimmed? The city will make them if social pressure doesn't do it first.
