I'm confused by the term total square footage. In terms of a house plan, what does it mean? Does it include all the usable space of a house?

The total square footage of a house plan is the sum total of the areas inside the exterior face of the heated walls, that is, it does not include areas like garages, porches, or decks. Consequently, you cannot determine the actual square footage of a house by adding the square feet of each room.
