ANSI sketch requirements

[Terrel L. Shields]

FAQ about stairs..

Stairs today, gone tomorrow...so watch that first step down...

 

[DWiley]

I was asking if ANSI requires it. Thanks

I think there are two ways to look at your question - literally and practically.

Literally, the ANSI standard is about how the size is measured and calculated. It does not address how one draws a sketch or floorplan, though it uses floorplan diagrams to illustrate proper application of the standards.

Practically speaking, the GSEs require reports to include the calculations for the size, and most appraisers rely on the automatic calculations from their sketching software. Using such software, if the stair areas are not included in the floorplan diagram, then the calculations will not be consistent with the ANSI standard.

Great Answer - and good logic

Each time an appraiser has a question on ANSI regarding our appraisals, it confirms that ANSI was a bad idea implemented by Fannie.
And this thread shows the confusion which validates what I knew all along.

what if the stairway has a pitched ceiling and some is less the 5 ft . what a joke

Wrong!!! You both got it totally wrong. You don't even understand standards. Neither of you.

If we ask if some standard X requires Y, it is understood that we are asking if that standard requires Y for conformance. You could also ask if X requires Y under conditions Z. But without the stipulation of special conditions, the question is whether X requires Y under ANY conditions.

The ANSI standard has NUMEROUS statements on stairs, such as sections 3.5-3.8, numerous diagrams of how to display stairs in its figures. If you are to include the stair area in the finished area, and that is usually calculated via CAD from the drawings - you will include that as necessary support for your calculations. -- IN ORDER TO SATISFY THE STANDARD.

DW has a problem here. [ But geneally speaking most I am sure appreciate his conributions. ]

Sorry... but you are wrong. Nothing in ANSI refers to the sketch that appraisers include in their appraisal reports. And that was the question. ANSI Z765-2021 does provide information about how to measure stairs and include them in area calculations.

What ANSI requires is that the area of the stairs/landings be included in the size for the level from which they descend.

Look at figure 2 in the ANSI standard. The area to be included is shown in red dashed lines, and that includes the area of the stairs, which I have highlighted in yellow below. In order for the auto calculation in the sketching software to be correct, the sketch would need to include the stair area (yellow highlighted area). Some also insert a graphic to show the stairs, others just include the area and insert "stairs" in that area. The ANSI standard does not stipulate doing it one way or another.
