Unless it is mandated for ALL appraisers, I doubt it gets past the state boards beyond that although measuring might become an EZ CE...
I'd hate to think I need to apply ANSI to a barn or poultry house considering they are 400'-600' long and 40'-66' wide...duh. All the company calculations relate to that metric, not 55.2' x 500.7' and would be a pointless waste of time.
And since assessors don't apply ANSI, and most Realtors use "Courthouse" as a SF source....well, again. What is the point? False accuracy? Is that a goal? Errors still remain. I just appraised a place where I also had another appraiser's sketch to look at. His SF? 3590. Mine? 3,615. The assessor? 3,904. I am not sure how they made that error but in a house, in this case, that had 25 different corners....??? It only takes a foot here, a foot there to err. And the difference in mine and the other appraiser (whom I knew and actually took classes under) was the difference in him using half foot and me rounding to a full foot. In any case it was inconsequential.
And are you really using ANSI or ASM?
Many agents (and appraisers) claim to be using the ANSI ® measurement standard, when in fact they are using the American Measurement Standard®.
