You could have 10 appraisers. All with the same measuring device and end up with 10 different sets of dimensions. So how do you determine which one is "right"? It becomes worse if they are all using a different measuring device. One uses a disto, one uses a fiberglass tape, one uses a wheel, one uses a steel surveyors tape. Which one is "right"?Again, look at it from lender or GSE standpoint. If they see several appraisals and one measured using ANSI and others took whatever source.................
And the numbers vary big time?
You can see GSE concerns.
They want a standard.
That is reasonable. Put yourself in their shoes.

Hard to have a "standard" without a "standard" Meaning, if you want everybody to measure to a "standard". Then you will have to have a "standard" device that conforms to that 'standard".The bottom line in all of this, no matter what your preferred methods and instruments are, it often takes logic, off-site reasoning, and most importantly reconciliation to measure GLA. ANSI doesn’t address how to square the theoretical exercise of measuring a home with the actual practice. It’s like paired sales, it’s never as easy in the real world as it is in the textbook. Hence the need for some educated human judgement.
As far as the scanning apps go, even in the hands of an appraiser, they are nowhere near as reliable as a tape and laser. Accurate within 2 inches on an 11 foot interior wall? How is that ANSI-compliant? And what was the control? A tape measure in the hands of a professional!!!

What happened to; American Measurement Standards ??Collateral Risk Network Standards Committee
Gross Living Area Measuring Standards – Announcement
The Collateral Risk Network (CRN) announced today its formal endorsement of the gross living area
measuring standard developed by the National Association of Home Builders (NAHB). This standard,
published by the American National Standards Institute (ANSI), entitled Square Footage - Method for
Calculating, establishes a protocol for calculating gross living area in single family residential homes.
Joan Trice, Founder and President of the CRN states, “gross living area (GLA) is one of the most
important inputs in a valuation report. It is imperative to set and adopt a standard that can be applied by
appraisers as well as other stakeholders. As the appraisal process is undergoing major shifts towards
modernization and new levels of automation, this void was ripe for a solution. The CRN applauds NAHB
and the Home Lab for their efforts in developing this standard.”
The CRN Standards Committee has identified the following key drivers for recommending the ANSI
Square Footage - Method for Calculating standard:
• ANSI is an internationally recognized standards setting body
• ANSI Z265-2021 has been developed by experts working at and in conjunction with the NAHB
• ANSI Z265 has been adopted by the states of Kentucky and Mississippi ***
• By endorsing this standard, the CRN is encouraging emerging technologies to develop applications for
gross living area calculations in a more uniform protocol
Mark Walser, President of Incenter Appraisal Management and CRN member notes, “we stand in
solidarity with CRN and the NAHB in the adoption of a trusted and reliable standard as the appraisal
profession works to meet lenders’ need for faster, accurate and compliant valuation reports. Digitizing
processes through new technologies helps fill this gap, and appraisal professionals must have full
confidence that their measurements meet standards. The adoption of ANSI is a critical step in that
direction”.
The CRN Standards Committee, chaired by Elizabeth Green, Chief Product Solutions and Data Officer
for LoanLogics, is working to provide a resource to the residential mortgage lending industry. The CRN
Standards Committee will develop a practical “how to” guide to demonstrate the features and benefits
including such topics as:
• Difference between current approaches
• Technology impacts
Nothing changes regarding comparables we use whats provided in either Public Records or whats in MLS out here most do not even make any GLA adjustments unless the variance exceeds 100 Square feet . Just do what you have always been doing as it worked. I also am not using any disclaimers as they are typically worthless and just give someone a target to shoot at. I am ANSI Certified and thats my story and I am sticking to it.ANSI Measuring Standards
The ANSI Standard for Measuring Houses, ANSI Z765-2003, is considered to be the current acceptable standard for measuring single-family residential detached and attached structures in Columbia, South Carolina.www.palmettosouthrealestate.com
Anzi is common sense and simple - the only hard part will be reconciling a comp that we do not measure or inspect to ANZI but I have been trying to do that anyway wrt what areas they include or exclude. A disclaimer that we are not architects and that even with usin ANZI standards our sketch and calculations might differ from another source.
THE END
If having an Anzi standard officially adapted for appraisals as an assignment condition turns into a witch hunt for super precision only then would it become a problem.
