basic stairs question


so, i'm rebuilding my porch steps. it's my first time doing stairs.

the old ones had four steps, the porch floor being the fifth. there was concrete pad off the sidewalk, but the old steps just missed it and were in the dirt propped up on bricks.

since the sidewalk/landing pad run downhill and are drastically unlevel, i decided to add a step and determine the rise from the low point, rather than the high point.

the old ones at the low point had a 10" rise, with the rest being 7 1/4.

so, i spent a bunch of time hand picking fir stringers. decided on 6 1/2 rise, 11" run.

even cut each run 1/4" out of square to allow for water drainage.

scribed the bottoms of the stringers, and trimmed the higher ones to get all treads level.

and THEN, i realized my critical mistake!

with my mahog treads, which only measure 11 1/4 fully, i hadn't left any room for a 1" overhang. the bullnose basically lines up flush with what would be the 3/4 trim. balls!

so, tomorrow it's back to buy four new stringers and do it right.


the question is, what should i make my run to allow for 1" overhang and still meet code? i also need to make sure i hit the concrete pad, so i think i can get away with a 10 1/4" run. would that work?

thanks!

If you are recutting the stringers, cut them level and use two boards with a gap in between to allow for drainage. A 12" board will cup. Seal all surfaces of the stairs, before installing.

Not knowing the distance between the stringers, I'd use 2) 2x 6 for the tread for open risers. You could get away with 5/4 stock for closed risers.

Also do not forget to take off your tread thickness from the bottom of the stringer.

Good luck.
