Are you a developer or the eventual owner/occupier? 

If you are developer doing a spec building, LEED Core & Shell gives you better flexibility than NC. 

If you are the building for your own use and you lease a portion of the building to someone else, you should require a 'green lease' clause whereby the tenant commits not to negatively impact the LEED rating with their fit-out, operations or business practices.

You also might consider asking the tenant to get certified or at least adhere to LEED Commercial Interiors standards.
