I have continued with the education modules and had the opportunity to inspect a friend’s home that is going on the market. This is my second mock inspection. Home was built in 1929. I observed the floor joist notched under the first floor bathroom as seen in pictures. I reviewed old forum posts about floor joist notching as well as the NACHI education materials. I couldn’t find anything that would permit this kind of notch. In my mock inspection I noted it and called out for further evaluation and repair. FWIW no sagging was observed in floor above this joist.
My narrative was:
“Floor joist below first floor bathroom observed to be notched improperly and in such a way as to significantly weaken the joist. I recommend that a qualified contractor evaluate and repair as necessary.”
Am I missing the possibility that this notch was accounted for structurally in some other way? There is one piece of blocking installed as seen in pictures. And the notch is only about a foot off of the end of the joist which is supported by concrete foundation.
I appreciate any feedback and insight as I continue learning. (I also called out the water stain on plywood in background of second photo that is under bathroom sink)
