In the same style homes, the frame model is slightly larger inside than the block and stucco version.

How are you computing the square footage? Seems like the easiest way would be to multiply the exterior numbers and back out the garage figure....with the thickness of the walls probably being the pesky number difference you are getting.

No house here is EXACTLY like another of the same style it seems. Some models are stretched or kicked in some areas when built as a spec home or as directed by the owners.
