What's the maximum riser height allowed on an outdoor stair? Is it still governed by IRC 311.7.4.2 which states max is 7-3/4"?
 
That's my understanding, if it is a component of a means of egress, such as the exit discharge leading from the exit door to the public way. Otherwise no requirements other than the designer's judgment and tolerance for liability.
 
I checked the state amendments and they allow 8 1/4" risers. It appears the building code does not address exterior site stairs that are not attached to the building. Not that I want to go higher than an 8" riser anyway, was just curious if there is any limit on ones not attached to a house or building.
 
Like sleepy said, if it is not the required egress path to the public way, then any other steps/stairs, unattached to the house, I consider landscaping.
 
It comes down to a "risk management" issue. What are you willing to accept vs how much insurance do you carry?
