Help on Lease Language for Main House vs Mother in Law Suite

[Jon S.]

What is the language used in a lease to indicate that the mother in law suite is not part of the rental? I'm renting a house to a new tenant, but not renting the mother-in-law suite that is behind the house. I want to make sure I use the correct language to indicate that the main house is being rented, and the mother in  law suite is not.  Has anyone else had a similar situation? 

Thanks

Jon
