Of course it will, nothing non-pressure treated below grade.

With a complete adhered or liquid waterproofing barrier approved for OSB I wouldn't be greatly concerned. Except for that unprotected bottom.The builder will be long out of liability before any damage shows itself.

Grade raised 6" up puts you what looks like the bottom lip of the porch overhang (which may be too close there too). And I see no damproofing/waterproofing on the house (and porch) foundation wall. Any portion of exposed concrete needs to have a damproof/waterproof applied to just above grade (yes, most builders will leave it off a porch foundation to save about $18).

For the pillar, if raised grade height was a last minute change, the bottom plate should have been raised for that with CMU grouted solid, then treated as the rest of the foundation walls. Having the cultured stone veneer exposed below grade is a no-no as well. And I do not like the bottom plate "glued" only, even if this is just a faux pillar.

The first thing I would question is why you are raising grade to begin with.

This is a zero entry house so I guess the grade is higher than it would be otherwise. No last minute grade changes are being made. Grading hasn't been done yet. But I noticed that if the grade is somewhat close to the level of the garage floor& future driveway, then it will be above the OSB. To keep grade below the OSB would require a hole between the porch and sidewalk or steps in the sidewalk going down then back up- which we don't want for a zero entry design.

Zero entry where you walk does not mean the "soil" has to be zero entry too. Your grade must be 4" or 6" (depending) below the top of foundation per code and slope away 5% to direct water away from the house. All the top of concrete elevations should be notated on the construction documents - and those were set with a grade elevation in mind. So bring up your concerns about the grade or find out what is planned/was designed and reconcile with the builder.

Good points about final grade and the veneer stone install, which should include a weep screed and a 4" clearance from grade, 2" from a paved surface.

As a Minnesota building inspector, I would fail this for all the reasons stated above. This home was not designed to be zero entry and at this point only a ramp or bridge will solve grading issues.
