What numbers did you come up with?

Did you include "House Circuits" in your calcs? (exterior lighting, specific loads, etc.)

Are the units using Non-Electric Cooking equipment?

Any Elevators? (possible ADA requirements),

You mention this is a "Renovation", what are the existing Service spec's and details?
Also, what is fed at each unit?
