Massachusetts
I live in a non smoking building, we all sign in our lease stating that we do not smoke. The tenants on the other side of my wall smoke and my apartment always smells like an ashtray and there is a black film over everything. I told my landlord and she asked them and they said they don't smoke. She is not an experienced landlord and this is her only property, I don't think she knows what to do. Can't they be told to leave? Isnt is a violation of the lease?
