Your answer will differ from place to place, but I have seen "Drip line" used to determine SF. I am helping a client now and we have to pay for the drip line of the building which includes some external atrium type architectural features that have NOTHING to do with the space he is actually using.
Is it reasonable to expect that you will have to pay for areas you will use...yes the landlord should be able to charge for these areas.
What ever the size is noted on the lease will prevail, not what was advertised.
