You want to show us where ANSI ever said you don't or can't include converted space as part of GLA? Let me help you a little bit. The term 'Gross Living Area' does not appear in the ANSI Z765 standard. ANSI Z765 is about measuring and calculating the square footage of a residence. FNMA (and the other GSEs) call the above ground, heated and finished areas GLA. The ANSI Z765 has existed since 1996. FNMA decided they wanted the residences they lend money on to be measured using the ANSI Standard. NOTHING CHANGED except now all resideintial appraiser doing appraisals destined for GSE loans are supposed to use the ANSI method for measuring and calculating the square footage of the dwelling. It's been 5 years. Surely the well to do 'Nando' can spare the $25 or so to buy a copy of the ANSI standard and to actually learn how to use it.
FYI:
To Grok: I am sure that around 2016, Fannie Mae's guidelines allowed an exception for homes built into a hillside.
Grok: "You are right that Fannie had language like that. I understated it earlier.
Around 2015-2022, the Selling Guide still said two things at once.
Default rule (same as now):
A level is below-grade if any portion of it is below-grade. A walk-out with finished rooms is not in the above-grade room count. Only finished above-grade area goes in GLA.
Comparison exception (the hillside paragraph):
If comparing above-to-above and below-to-below does not fit the style, the appraiser could deviate. Fannie’s example was:
That is the exception you remember. It was not a blanket hillside waiver. All three tests had to fit: lower level substantially out of the ground, finish equal through the house, and the market treating the layout as one living area. Appraisers on the forums quoted that exact sentence from the Selling Guide in 2017.a property built into the side of a hill where the lower level is significantly out of ground, the interior finish is equal throughout the house, and the flow and function of the layout is accepted by the local market, may require the gross living area to include both levels.
What that did not mean
- Ordinary walk-out basements on flat or mildly sloped lots
- Finished basement that is still mostly in the ground
- “The market likes daylight basements” without the house being a true hillside design with continuous finish and function
That hillside-GLA example is gone from current Fannie/ANSI policy. Grade is mechanical: any portion below grade → the level is below-grade finished area, not above-grade finished area. Value is still recognized on a separate line. GXX001- is retired and was never that hillside paragraph anyway.
So: yes, circa 2016 Fannie expressly allowed both levels in GLA for a true built-into-the-hill house that the market treated as one living area. That was a comparison/style exception, not a redefinition of grade. It is not available on a current Fannie ANSI assignment."

Grok: "It lived in the Single-Family Selling Guide, B4-1.3-05, Improvements Section of the Appraisal Report, in the Gross Living Area discussion — specifically the subsection on comparing above-grade to above-grade and below-grade to below-grade.
That is the same section appraisers cited in 2015–2019 as “pages 581–582” of the then-current PDF guide. The hillside sentence was Fannie’s own example of when the appraiser “may need to deviate” and “may require the gross living area to include both levels.”
When it came out of the Guide
Fannie does not publish a redline that says “hillside paragraph deleted.” The workable date is the ANSI rewrite of that same section:
- Announcement SEL-2022-03 (April 6, 2022) rewrote B4-1.3-05 to require ANSI Z765-2021 for GLA and non-GLA.
- Compliance for delivery: appraisals with an effective date on or after April 1, 2022.
Practical timeline
| Period | Status of the hillside GLA sentence |
|---|---|
| Mid-2010s (including ~2016) through early 2022 | In B4-1.3-05 as a comparison deviation |
| Appraisals effective April 1, 2022 and after | ANSI controls; that sentence is not in the Guide |
| Aug 8 / Sept 8, 2025 | GXX001- also retired; no leftover opt-out that restores the old hillside GLA treatment |
