Second floor retail?

Derek Rubinoff

For a two-storey retail building, with only the front facing a street, how should the second floor exterior wall be measured? How about rear walls on the first and second floor?

I am using Revit as a tool, but Revit, for "store area", is attempting to include the rear wall--should I force it to take the area boundary at the inside finish face/inside glazing face?

Only the street frontage wall should be to the exterior building line. Everything else around the perimeter is measured to the inside finished surface.

I would like to add that the store area (measurement to the building line) can also occur on the second floor retail.
