Probably alringht Joe if that is not a bearing wall with any type of uplift or lateral reactions.
Typically, the concrete floor would have been pured over the brick wall with the anchor bolts cast in that. :slight_smile:

Sorry if the picture wasn’t clear. It’s a pier and curtain wall foundation (crawl space). All photos are the perimeter foundation wall. It certainly is a bearing wall. Two pics are from a house under construction beside the one I inspected. Same builder.

P.S. The purpose of foundation anchorage has nothing to do with bearing. Is is to prevent the house from moving off the foundation wall during high winds or seismic events.

Then I state the last sentence of the post above. :slight_smile:

Shouldn’t the bolts have been anchored into the concrete and not the masonry? I imagine that the brick is a veneer and tied into the concrete with ties, which aren’t going to be good at resisting lateral loads.
