I have a super annoying neighbor who rides up and down the street on his gas powered scooter all the time, often as early as 6 am and as late as midnight. We have politely asked him to stop, and he gave us the finger. We have tried calling the police but apparently they have better things to do. We have tried contacting their landlords but so far they do not seem willing to step in. My question is does a landlords obligation to provide quiet enjoyment extend to neighbors of surrounding properties not under their management? I'm just wondering if I have legal leverage into forcing the landlord to take action or else face being taken to court over failure to mitigate the nuisance. I really don't want to move, but I can't go on enduring the noise of that scooter.
