Raised Slab On Grade with Cracks

[zero1238]

I inspected a home today in a nearby town that was a two-story dwelling constructed on a poured concrete slab foundation. On the left side of the dwelling existed a masonry block retaining wall approximately 36" off of the side that was 20" taller than the adjacent grade and that also separated the grade elevation of the subject property and the neighboring property; a difference of 24". There were some cracks in the foundation on this side, however, I believe they were caused by the poor grading and drainage conditions along this narrow/confined strip of property between the dwelling and the retaining wall. Other than possibly reinforcing the retaining wall and improving the drainage problem by either connecting the downspouts and running them out to the street or installing weep holes within the wall, should I be overly concerned about the 24" difference in grade elevation that is 36" from the base of the concrete slab foundation? I'll attach some pictures for clarification.

Thank you in advance for any feedback.

Unless there is obvious settlement of the main slab and you see cracks related to settlement, I'd not be concerned. Assume there is no frost to be concerned with there.

No.

@oldestguy

Why wouldn't you be concerned with frost?

OG on frost. With practically no depth of this "slab" foundation the site likely is in tropics, etc where there is no frost to affect foundations.
So where the heck is it?
