Lease for Long-term Renting by the Room

I have a client who wants to rent her home out by the room. I usually get my leases from here at BP but they don't address "common areas" ect so I feel like she needs something a little more specific. 
Does anyone have a lease for Michigan that they would be willing to share? Or where did you get your leases for renting out a room long term? 

Any extra advice is always welcome! Thanks!
