You can't measure your subject with ANSI when your compables structure size is not ANSI.

I can see why they would trust a third party to measure and draw the improvements. Appraisers are all over the place. I have seen plenty of appraisals that represent the improvements by rectangular boxes that calculate to the assessor's GLA.

Floor plans:These are views looking straight down at the floor, showing precisely dimensioned rooms, closets, kitchens and baths, and the locations of doors, windows, stairs, and other interior elements (at left).
That's not real plans though. That is a floor plan for marketing.
OMG! included 12 SF for fireplace for a 2,800 SF house! Idiot! We are screwed!
Right you are, but where did they get the dimensions? Marketing something that is not real is illegal. My guess is they got those dimensions from the architects's floor plan. And that should be what the builder submits to the county. In California, the county uses that as the official GLA.
I have appraised homes that were built 2 years ago type time frame to discover the county record is wrong. The floor plan and GLA did not match what was on the lot. And that's why appraisers measure the improvements to know what's really there, what was added on, or a mistake was made initially recoding with the county.
