Square footage is in the eye of the beholder.  Appraisers, real estate agents, home owners and tax assessors have no formal guidance.

Square footage of a home is a matter of debate -- a homeowner measures it one way, a real estate agent another way, and an appraiser a third way. 

The local tax assessor has his own method, too.

So, who is right?

Until 2003, they all were!  That's when the NATIONAL ASSOCIATION OF REALTORS® Appraisal Committee defined the term "square footage" to include the following:

Finished square footage on each level of the home, measured from the exterior-facing surface of outside-facing walls.

The committee defined "finished" as an enclosed area that is suitable for year-round use and includes walls, floors and ceilings.

Seems basic enough, but there were some added notes and exceptions:

  1. An opening to a floor below (e.g. vaulted ceiling, open-air living room) is not included.
  2. Stairs are counted as square footage and are added to the floor from which they descend
  3. Finished areas must have a ceiling height of 7 feet to be included (except under duct work or beams in which case the requirement is reduced to 6 feet, 4 inched)
  4. If a room is sloped, at least half of the room must have the minimum 7-foot height in order to be included
  5. "Detached" finished areas are only included if they are connected to the main structure by another finished area.   Detached garages, therefore, are excluded.

Even with the standard defined, the Appraisal Committee's approach to square footage is still just a guideline; no states have formally adopted it as a standard for appraisers, tax assessors and other real estate industry players.

Until then, the debate will continue.  Despite the "official" guidance.

Square footage is a debate.  Room dimensions are even worse!  Oddly shaped rooms, such as those with dormers, are hard to put into an X by X category.

Nice post on the facts.  I'm pretty fed up with the whole issue since we can't post the SQFT on our listings.   It's hard to judge apples to apples without knowing it.

The state of NC requires us to measure their way. We measure the outside of the house so a stair case counts as sq ft on both floors and floors with sloped ceilings count down to the point the are only 5 ft tall..

Buyers think I've lost my mind when I tell them that all I can do is hold one end of the tape measure when they want to know the square footage.  Unless it's on the official tax record, I am not allowed to measure or give an estimate of square footage.  I've been instructed to refer them to an appraisor.  Good to read about this issue in your blog.

My advice to ALL Realtors, per a conversation I had with an attorney with the California Association of Realtors is, DO NOT EVER MEASURE any home.  UNLESS, of course, you're am appraiser or surveyor.  When I first moved to my current area, many of the Realtors were still measuring their listings. I REFUSED. And that is when I called the C.A.R. hotline.
