The project has two large buildings which have an intertwined 3rd floor. Building A has retail space on floors 1st & 2nd and then residential on 4th-17th floors. Building B is 100% commercial space (with future tenant fit out) occupying floors 3-13. Both of these buildings share one utility meter.
My question is, can we combine these buildings and go for one certification? Could it be CS? There is more than 60% future tenant fit out space so it seems this would be most appropriate. Then, how would we handle the residential portion? Can a CS building be residential? OR, would the building have to go for NC (because of residential portion) and write tenant guidelines?

Thank you!
