mtlogcabin, thank you. that's the way I also read it. Your wall would have to meet the footing width of Table R403.1.
The only place we allow less than 12 inches is in on frost protected stoops.

The only place I have seen a wall w/o footings is Superior Walls precast, but they are engineered anyway, so I have not had to make the call on the illogical code contrdiction....yet....

A century ago it was common to excavate down to the frost line and build stone or brick foundation walls right on the subsoil. Stone foundations were typically 16" or thicker, so they didn't have projections at the botton. Brick walls would typically have a few courses corbeled out another wythe or two. The verbiage for the foundation wall to extend below the frost line is probably based on this archaic construction method.

It only took one hundred responses to go medieval on the thread. Gotta love this forum.
