Need advice on brewing neighbor war

[Jon Quigley]

Hello.  I have a new tenant who likes to hang in his garage and play music.   Level is well within city code and is played mid day at a level that wouldn't normally bother anyone.  But - one neighbor (who I've chatted with many times) is used to a quiet street and doesn't like it.   Both are good folks and have even had beers together but a war may be coming.   a) Where does my responsibility as a landlord end such that it's between the tenant-neighbor-city and b) any general advice?   Thx.

You have no responsibilities in the dispute at all as a landlord. It is between adult neighbours. The fact that one rents from you is irrelevant. Let them work it out.
