It's his house , maybe your car , garage door , shingles or your wife are an eyesore to your neighbor, what are you supposed to do ?
I live in a decent neighborhood, and you know what's expected of you when you buy. I get what you're saying, but to me if you live like you don't care about your neighbors, or what they think, then move into an isolated place. Plus it brings people's home values down when your place looks like shit. People who don't mow grass, etc. I'm sure they all have their reasons/excuses, but if you live in a neighborhood, respect your neighbors.
