The builder on this 5 year old house had his engineer look at the plans and his picture of this cut floor joist.
The engineer basically said this:
Based on the short span and the fact that the next adjacent joist is less than 24" from the foundation wall, the notched joist is an irrelevant structural member and therefore, no repair is needed.
Note how he did not specify the span or the exact spacing of the next joist to the foundation wall. It was not what I would call a “short span”. If my memory is good, I think the joist is under some kitchen cabinets and the drain pipe goes to the upper floor.
Nothing in his letter even indicated that he visited the property.
Anyone ever run into anything similar?
