This house had experienced both slope creep damage from the hillside movement and also local saturation of the soil underneath the house. both causes created a similar effect which is stucco cracking, sloping floors, and drywall cracking.
However because the conditions were not severe enough a retrofit by underpinning stabilization and lifting was not prescribed.
It was only prescribed for the pool.
