Assumptions and estimates for when the ANSI measuring standard becomes the rule?

Apparently not all assessor's offices are the same. Your assessor obviously doesn't measure to ANSI standards. Some county's around here do (and some don't). Granted it can be a mixed bag so I need to look at the comp sketches. It would stink to have to pay for that! I won't pay for a sketch.

So your assessor does measure to ANSI standards. When was the last time your assessor physically measured every property. Asking for a friend.

Everything must reconcile. So you can't just be off by one measurement and get away with it.

In surveying, when the assumption that the errors are systematic, then the gross error is allocated along the traverse to each portion of the traverse. That's problematic I would presume in a house.

I'd say in at least some cases, the errors are the result of an occasional lack of attention by someone who could most likely do better if they really tried. Maybe in more cases, the appraiser just doens't have much confidence at all in his measurements and struggles as best he can to throw in values to make a floor plan that resembles the real thing and provide the correct GLA. And in some cases, the appraiser, most likely a trainee, flat out lacks the competence to do a floor plan by himself. Are these things "systemic"? Not unless you categorize motivation and competence or lack thereof as a problem related to the appraisal system. Yea, I guess that is possible.

I still say and think this is not about the precision of measurements.
What this is really about:

1. Stating you perosnally measured the property.
2. Properly identifying and quantifying the actual Above/below-grade areas;
3. The Actual Environmentally controlled Heated/cooled areas.
4. Differentiating between areas of different Quality/refinements
5. Identifying Attached ADU's and it may or may not have access to the main house.

6. I just completed an SFR assignment. The owners gave me a copy of the prior appraisal. When they offer it, I don't turn it down.
to make this a short example. The Appraiser clearly did not measure and then transfer those dimensions to the sketch. The Appraiser used the County Tax assessor's sketch. Were we both close? Yep, there was a difference. He made two mistakes. His attached garage sf 500sf. Same as the County, My measurements of the garage came out to 600 SF. I measured the depth, he did not. The second difference; His GLA 2191sf. Mine was 2215sf. Actually it would be a little wider spread because he included some non-GLA area as GLA. That was only 16sf.

So would this difference have a quantifiable effect on the MV. Probably not! BUT, combine this GLA difference with other sloppiness and its very possible it could.

I paid for an assessor's sketch today to see why I had 1890 sf and the assessor had 2015. This is my sketch. No errors Terrel. Of course, the house was listed as a three bedroom house. They put a toddler bed in the corner of 508 sf garage conversion. I wonder how many appraisers just accept that?

House must have been built by the best builder in US. It is perfectly square to the tenth of an inch.

Pretty accurate. I have a total GBA of 2327 sf, garage of 438sf and GLA of 1889 sf. The difference to the tax assessor is 126sf, which appears to be the covered patio which you have as 15x8'=120sf.

Ansi this or something like it. I bet you can knock them out in a hot minute. LMAO.
