Who is it for?
Welcome to the world of residential square footage.
In April of 2022, Fannie Mae will mandate the use of the ANSI measurement standard for all interior inspection appraisal reports. This is history in the making and a giant leap forward for consumer protection.
This is the first step in bringing together the entire real estate industry and changing the over 100 different names for finished living area into one language of real estate. It’s time for the real estate industry to join the rest of the standardized world.
ANSI is “The Name.” It is known world-wide and offers consumers a level of trust to ensure that the same home purchased in Nashville, New York, or San Francisco will all be measured the same. Since 2003, Hamp Thomas has been promoting the adoption of one nationally mandated measurement standard.

The American Measurement Standard® is a voluntary standard for the measurement of residential square footage. For those professionals who choose to provide this service, the AMS® helps to promote the public’s trust, as well as offering a consistent, reliable, reproducible, and defensible source for the methodology utilized in the collection and communication of square footage for single-family dwellings.
The employment of a written “statement of square footage” is encouraged for the advancement of professionalism and consumer protection, by all those that create and communicate residential square footage data. In this, the information age and the era of technology, it is our sincere hope that the real estate industry will embrace the adoption of a universal measurement standard, mandate it, and educate all professionals about the importance of credible living area data. One industry, one standard.
The Home Measurement Standard was released in the fall of 2021 and is what Hamp refers to as “ANSI on Steroids.” It is a formal standard of measurement that offers professionals a document for formal disclosures to show how specific measurements are calculated that are not covered within the sixteen pages of the ANSI Standard. For real estate professionals, all books are library learning products and whether you are a thirty-year veteran appraiser or a brand new trainee or agent, this is information that makes you more valuable to your clients. In this day and time, the real estate industry must join the rest of the standardized world. So, welcome to the world of square footage and all the information you need to help you hone your craft.

Residential square footage standard for use by real estate agents, appraisers, assessors, architects, home builders, insurance agents and adjustors, and anyone who cares about the professional reporting of a home’s square footage with the ANSI standard, which features 16 pages total including three pages of the written standard and five sketches for an extremely complex topic. The HMS has over five times more data and removes all the subjectivity the ANSI leaves unaddressed.
The new "Name" is measuring residential square footage.
In a Zillow world where real estate values are based on a price-per-square-foot formula, using the square footage details from county tax records. Those tax records are created with zero interior inspections and are inaccurate about 95% of the time. Accurate square footage details are not their goal and not required for their purposes.
The real estate system has been lost. It was created without any clear path for the future and consumers will now pay the price to fix it. Without an industrywide measurement standard, the chances of square footage errors in public records are guaranteed.
Every component of a sf home is measured by a national or international measurement standard. But, once they are combined there is no one standard required by all those who use that data.
It’s time for the real estate industry to join the rest of the standardized world and for agents, appraisers, assessors, and everyone who uses square footage top use the same method and practices, and all of us use the same categories for reporting square footage that allow for fair comparisons and consumer protection.
Consumers deserve to know the fair size of their single, largest, lifetime investments...
The ANSI 2020 update started in early 2020 and in April 2021 we are still waiting on its release. The changes that appear to have been approved and anticipated are minimal at best. Appraisers and agents wrote in asking ANSI about one specific topic where they hoped for a simplification of a measurement in rooms with sloped ceilings. But, the new sketch that appears to be in the standard may be even more complicated and leaves this measurement with the same degree (or perhaps even more) of problems that it had before.
What we hoped to replace with one simple line has been replaced by an expanded text that leaves this measurement even more debatable. Two people can measure it in different ways and both claim adherence to ANSI.
That’s too complex for something that could be easily resolved with one simple Yes or No statement. Either Yes add for the exterior walls, or “NO’ do not add for the width of exterior walls. Something that seems very simple to those who actually take the measurements is being written by home builders who perhaps do not understand the practicality of the measurement. That brings us to the heart of the problem. Many people have talked about this over the years but don’t want to speak it out loud since they have no other measurement “standard” options. Well, now they have a choice, we can say the things out loud that used to be exclusively spoken behind closed doors.
ANSI was created and is always lead by the National Association of Home Builders. The director (since the start of ANSI) made the comment that ANSI was created to be simple enough to be understood by teenagers. While it’s a nice though, the topic of measuring square footage is very complex and much too complex for the vast majority of teenagers. If this was 1950 style homes maybe we could get away with a simplistic standard. But, with todays designs and construction methods, a measurement standard must have much more than sixteen total pages.
