I have a change in subfloor height to contend with. For whatever reason at one doorway of the house the subfloor was built 3/4" (19 mm) higher than the neighboring section.
I can install a tapered board here so that the rise would take place over about a 5" (125 mm) run. However with carpet over this I am concerned it may not be visible enough and could be a trip hazard.
Any tips on whether this is really a concern and if so what to do about it?
There is no practical way to alter the construction to get all the subfloor in the same plane. But I might be able to extend the run of the transition to about 10" with some localized alterations to the subfloor just at this doorway. The doorway is through a 10" thick wall.

There are shims made for these situations. Have a look
These are made by traxx. Ask at your local carpet shop or order on line
If you take a look at the link you will see a variety of options including one shim that is 24” in the ramp from 0-1”. In my opinion this is a good fix for a transition like yours and is easy to walk across. You can of course ask your local AHJ about code compliance.
