Live in landlord, need a lease term preventing working from home

[Jean W.]

Hi I'm Jean, 

I have a small property that I am a landlord of. I live in the house with tenants. And have a back house that I rent to a tenant separately.  

I currently have one live in tenant, and I want to have a room lease term in the lease that does not allow tenants to work from home. I already have a term that does not allow them to have a home based business.  My live in tenants are always month to month. 

Are there any legalities against this?
