Dealing with hoarding tenants

[Peter Kopchik]

I have a 2 family house, I live on 1st floor and have tenants on 2nd floor. They have a lot of stuff borderline hoarders. It started small but they keep accumulating more stuff on their porch, their stairs and the patio below them. I did not set a good president from the beginning, but I also thought they would be cleaner and take care of their stuff and my property better. I know the stairs are a liability that needs to be addressed immediately. What are my options? Can I tell them that they can't have all the stuff on the porch? The porch is theirs exclusively. How about the patio(common area)? With all the chairs (that never get used), ladders, flower pots, pressure washer, and much more, the area is not useable for anyone and maintenance of the area is so much more laborious having to move their stuff. (They never clean the area). Any help is appreciated.

@Theresa Harris Thanks, yeah I talked to the husband about clearing the stairs off. He said okay but that was 3 days ago. Break in with ladder is not a concern they aren't tall enough. Fire risk,  liability, maintenance  are all issues. I'm wondering what actual rights do I have to remedy it, if they push back on fixing it, or don't do it in a timely manner.
