They are also the people that could be gravely injured in a minor stumble on a stairway. This is why building codes typically allow no more than 3/8" variance in riser heights. | |

If so, then the nose portion would obviously be thicker than 3/4" and then I should be pretty well good to go. | |

I've raised steps 3/4" with false treads, which alters the rise at the top by -3/4 and bottom by +3/4, and haven't stumbled at all. | |
