Overhang on steps

[notbob]

Is there a necessity for the tread overhang on stairs/steps? If so, what is it?

Yes, there is. According to the books I read it's so that you don't hit your heel or toes against the riser.

Check out the site stairways.org. They have a visual interpretation of the recent stair codes with sketches and dimensions.

From the IRC

A nosing not less than 3/4 inch (19 mm) but not more than 11/4 inches (32 mm) shall be provided on stairways with solid risers. The greatest nosing projection shall not exceed the smallest nosing projection by more than 3/8 inch (9.5 mm) between two stories, including the nosing at the level of floors and landings. Exceptions: 1. A nosing is not required where the tread depth is a minimum of 11 inches (279 mm).

I've found it's easier to get a dolly (hand truck) up the stairs when there's a overhang. It's something about pivot points and other such magic.

The riser adds more strength if it is closer to the middle of the step where most of the weight is applied.
