Duplex Tenant Issues

[Frank Boenzi]

I moved a tenant into the upstairs unit about two months ago. It has been nothing but problems. Upstairs tenant is very loud and inconsiderate it seems and the downstairs tenants have been there for about a year. Have had no complaints about them. They have two younger children in the bottom unit. 

I have started the eviction process on the upstairs tenant. Have had four police reports and multiple complaints from downstairs tenants and property I own next door about this upstairs tenant. We are about 15-16 days in to our 30 day period. I got a text from the downstairs tenant saying that people were smoking cigarettes upstairs and it was seeping into their unit. She explained her child has asthma and it is very bad for him. 

I have no idea what I can do to solve the problem on the spot. The upstairs tenant is not cooperative and doesn't answer my calls. Any ideas on what I can do?
