During an architect's quality control review, the architect discovers the following code provisions for the minimum dimensions for all handrail extensions beyond the top riser of an egress stair:
-The state building code stipulates a minimum dimension that is two inches less than that required by the International Building Code.
-The local AHJ code stipulates a minimum dimension that is four inches greater than that required by the International Building Code.
Which code requirement must the architect follow for handrail extensions in the construction documents?
