Yes, the handrail needs to be returned.
Also, you said it was installed low, which also means it needs to be raised.
While the owner may have had it installed low for a reason, the safest height is to install it at the required height ... 34" to 38" above the line of the nosings (now it's called 'the plane of the nosings').
Leaving it low, then having an adult start to lose their balance, then reach for the handrail ... where is that handrail ... WHERE IS THAT HANDRAIL ... *WHERE* *IS* *THAT* *HANDRAIL* ... as they continue to fall because the handrail was not where it was expected to be.
I would definitely write it up.
If your client says 'Oh, great idea, I want to leave it at that height!', that is their decision, but in *my* report, the handrail would be written up as being too low.
You know, so when the attorney comes a calling for 'the surviving spouse' ...
