Inspected house yesterday in which the addition appeared to not be attached to the existing home. A foundation wall was poured but not tied into the house. In between the house and addition their is a 3 inch gap covered with siding. The floor in the home has shifted, and the deck attached to the addition has moved. There are no cracks in the drywall and the windows open and close OK. How would you write this up. Attached are photos showing the gap.
