I would say this is normal

BUT, its a flag that you need to keep an eye on. Foundations move with the soils ability to retain and loose water. After a while the shift might be too much for the foundation and it cracks. Please do not mis understand me, this is not something to just shrug off, but its something to watch and see if it gets worse. If you begin to notice that doors do not shut in that area, or cracks begin to appear in the interior drywall and stuff like that, then you need to consult a foundation expert.
