Grand Rapids Tenant Advice

[Jerry Westhoff]

I finally closed on my first duplex in Grand Rapids, MI.  The property currently has tenants upstairs.  The lease that I inherited does not list anything about access to the basement.  The tenants do have access to the basement though because they have a ton of junk down there.

My question is can I ask them to remove all of their items from the basement and change the locks to eliminate their access to the basement?  

Also can I ask them not to park in the driveway?  

Lastly, the house has a front porch and a back porch on the lower level.  The upper tenants access door is on the back porch.  They have made a mess on the back porch by attempting to grow plants out there and they are all dead and scattered everywhere.  Can I eliminate their use of the back porch?

The lease unfortunately does not cover these items so I am unsure about handling the situation.

Thanks,
