Tenant complaining about weed smoking neighbors

[Dave Bopp]

Hey Everyone,

I have tenants in one of my units who are complaining that the smell of marijuana and cigarette smoke from the neighbors in the adjoining row home are causing nausea and headaches. The neighbors next door are not my tenants- in this case do I need to take action to reduce the smell of the smoke since my tenants are claiming it is causing health side effects? My tenants asked that I speak to the neighbors to ask them to change their behavior (which I know isn't going to be effective) or fortify the basement wall where it seems the smell is coming through.

As a side note they are good tenants, but my feeling is that no matter what I do the smell is going to continue to be an issue.

Any input would be appreciated!
