Pre-Purchase Structural Inspection in Northeast Portland
Northeast Portland sells a lot of thoroughly renovated century homes, and the renovations are exactly what an engineer should be looking at. A finished third floor, an opened-up main level and a converted basement are three separate structural interventions, and a listing describes none of them that way.
The specific questions are answerable in a single visit. Did the third-floor conversion add framing, or lay a floor over ceiling joists? Did the opened main floor replace the lateral capacity it removed, or only the vertical support? Did the basement conversion cut into the foundation or the posts?
Retrofit status is the fourth question and the one most often assumed. A seller may describe a house as retrofitted on the strength of some bolts being visible, which is not the same as an engineered retrofit with adequate anchorage, cripple wall bracing and hold-downs. Partial work is common and is worth identifying before rather than after closing.
What We Look At Here
- Third floor and attic conversions for framing adequate to occupancy loads
- Beams over removed walls, and whether lateral capacity was replaced as well as vertical
- Basement conversion work for cuts into foundation walls or bearing posts
- Actual retrofit status: anchorage, cripple wall bracing and hold-downs, not just visible bolts
- Crawl space or basement condition, including post bases and sill plates
- A written opinion inside the inspection period, usable in negotiation

Questions
Frequently Asked Questions
The listing says the house is seismically retrofitted. Is that enough?
Not on its own. Partial work is common — some anchor bolts without cripple wall bracing or hold-downs is a frequent finding, and it is not an engineered retrofit. It is worth confirming what was actually done before closing.
