I’d be asking that question of your building inspector. I don’t think the lean is intentional whether or not it’s a problem is a question for the professionals

A structural engineer will be best adviser/. They look like they have all been added at a later date to prop up the floor; The 2 in question appear to be holding up the same beam/. Leaning towards each other should not be a problem as long as the props themselves are not bent and they have good contact with beam.

they look like temporary props installed pending permanent installation of new piers....like bigreader and kate both suggest i would be asking for professional advice but it does look like another example of the poor value of many building inspections that overlook or ignore obvious issues but maybe the acrows have been concreted into the floor but my husband suggest that it looks like more work is required!

These are Acrow props and are only used for temporary support to a structure while installing permanent structure. Theses ACROW supports should not have been cemented into the base. If they can not be removed, which looks the case, then brick piers need to be built around the temporary support, to permanently support the home. Doesn’t even look like the pieces of timber that are holding the structure are even attached to the floor beams.

Definitely employ a structural engineer to assess and advise.

I can only assume the inspector didn’t look under there. That is dodgy but fixable.

It's great to hear that your house's subfloor, piers, and foundation walls have no issues according to the inspection report. Regarding the leaning steel props, it's possible they were installed that way intentionally for structural reasons, but it’s always wise to be cautious. Since they stood out during your inspection, I recommend consulting a structural engineer to assess them properly. This will ensure they are functioning as intended and help you avoid any potential issues in the future.

Hopefully the owner has had the props reassessed by now. Since the original post was two years ago.
