Contract Wording for leaving the unit clean and tidy

[Kevin W.]

Hi BP!

I was wondering for those with experience, how do you word a contract for keeping the unit clean from debris or personal items when a tenant decides to leave.

I am helping a family member lease out their small commercial space to a nail salon business. I want to word it in the contract so that the tenants will leave the building free of debris or other items from their business. Ideally, I want the place to be like when they first rent it, but we all know that won't happen (since they will add various light fixtures and flooring).

Any advice will help.

Thanks BP!
