I think these regulations vary greatly by country.
For example, in Hungary, you can do a 20% ramp (1 in 5) in some cases where traffic is very low (up to 4 parking spaces). I am sure there are many regulations.
I would say a better approach is to set the various ranges in the Rules and Standards panel and save that as a Favorite.
For example, you would enable and set the Stair Pitch minimum and maximum values to 50 degrees and 75 degrees, respectively, for Ladders, so when you to start creating such a Stair, you would first activate this Favorite and go from there.
