Inspected a 30 year town home yesterday and found the front storm door and especially a first floor bath door way out of plumb. There is also minor cracking extending outward from where a first floor load bearing wall meets the ceiling.
In the very yucky, uncondtioned crawl there were no visible signs of stem wall cracks in areas that did not have foam board insulation. There is an overspanning of the floor joists (24’’ o.c.) with a horizontal span of at least 14’ - No support beams OR bracing.
I suspect (so far) that the overspanning may be the cause of the cracks where wall meets ceilng. But what about the settlement issues with the doors. I’ve been unable to determine the likely culprit and would appreciate your feedback. Photos attached. I already know about the rot in the joist pic which is beneath the front door.
