Accurate Sqaure Footage!

By
Real Estate Appraiser with Jeremy Cowin Appraisals

I get questions on a regular basis as the why sometimes what I measure is different than what is on public records....especially for condos that are multi level and guest houses that are detached from the main house.  Some agents I know just do a quick measurement around the exterior of a house na dguest house or the interior of a condo and base their info on that.  Some don't even bother and just base it on public records and assume that PR is up to date!    And altho, Public Records is a reliable source, it is good to have a house and guest house or condo properly measured.  There is the National Square Footage Standard that appraisers follow when measuring a home:

1.  The property must be measured for the exterior /outside walls

2.  measure to the nearest inch and report to the nearest whole square foot (round up or down)

3.  Include only finished areas

4.  Distinqusih between ABOVE-GRADE and BELOW-GRADE finished areas and identify which is which - basements do not count!!!!

5.  Do not no include openings in floors - ie open to below areas or stair wells - but do include the steps on the stairs

6.  Ceilings must be 7 Ft in height except under stairs, beams and sloping roof lines

7.  Include assessory apartments/units ONLY if they are CONNECTED to the main house by finished hallways and stairs - does not include the detached Guest House in the back!

8.  Do not include Garage area as part of the SF of the house

You can visit http://www.nahbrc.com/  or call 800-638-8556 and get a copy of this voluntary standard for your information. 

So even tho, your detached Guest House has permits, it will not be inlcuded in the GLA adjsutment, however, a good appraiser will do research and find its market value by finding comps that have a similar guest house amenity.  And just because Public Records states that a condo is 1200 SF does not amke it so if it a 2 story design with stairs or has an open area.

Hope this helps!

Jeremy,

 

Good post!  I usually refer to the standard as ANSI  Standard Z765-2003...which is what the NAHB orginally commissioned in 1994 and adopted in 1996.  Before that, it was nearly impossible to find out who measured what to come up with a total GLA!

Hey there Jeremy -

I wrote a similar post on ANSI eons ago - I find ANSI standards (is that redundant?) interesting and I do use most of their recommended ANSI suggestions, but I do wish that County Assessors, Builders, Architects, Realtors and Appraisers (etc.) would use the same rules whatever they might be.... For instance, if the County Assessors office includes a finished attic with 6.5' tall ceilings as finished, taxes it is such and the home owner uses the space, should it still not be used?  What about those darn dropped ceilings in kitchens?  If they fall below 7', do you not count the kitchen (and then how on earth do you explain that in the appraisal report... 'there is a kitchen, but it's not counted in the GLA, so their really isn't a kitchen'?) ... AND FOR CRYING OUT LOUD .... basements should not be part of the GLA in any case - I know that Realtors, Appraisers and TAX ASSESSORS will sometimes say it is, but the market (around here) disagrees -

It gets even more wierd here in Los Angeles, when appraising a property on stilts that sits on a  hillside and you enter the first level of a house or the garage at street level but the rest of the House is BELOW GRADE and the GLA is consistant with Public Records and it can be 2 - 3 levels below grade.  These standards are merely suggestions to keep info as consistant as possible, but there are "exceptions" to the Rule as with anything!

Basements here in So Cal can be given a "Value in use" if they are fully finished, but are never considered GLA.  The "California Basement" is sometimes entered exteriorly and sometime interiorly from a hallway or bedroom closet, and I have even seen access to them in the middle of living room and dining room floors with owners having to move furniture so I can get in to see!  Accessabiltiy has to be a factor as well!

Thanks for your comments!

Hi Jeremy, good to clarify this for those that are not appraisers, so they can see where we are coming from. we don't have many basements, so we don't get called out on measurements often. We deal with unpermitted additions or conversions though. 

Happiest of Holidays to you and yours Jeremy! :)

Jeremy,

I enjoyed your post.  I have just run into a situation with a sloping roof.  By way of background, we dont have many homes with a tudor or cape cod style, where the roof slopes to the floor in the upper storey.  Anyway, the appraiser measured to a 5' height.  Your post makes me even more wrong! :)

Anyway, my thought was that you measure the floor, and then everyone knows that the style of the home has that defect.  Kind of like the other comment of yours that I loved about trying to find comps that have guest houses for an appraisal of a home with a guest house. 

The problem I see is that the measurements for homes where the roof slopes into the living space are mostly done incorrectly, so who gets to bite the bullet first??

Anyway, thanks for the insight.
