I need to replace a set of steps that have a rise of 25" and a width
of 53".

The stairs land on a sloped concrete carport and the slope across the
53" is 2 inches.

How do I approach this?

The current stairs have 3 steps and then a small step to the porch.
Totally unacceptable and dangerous.

Thanks for any advice.

Make any risers supports come out even. Better to have four
"short" steps, or three "long" ones.

If the steps are not able to meet the concrete "square" (that is
there is a slope left to right as you face the stairs), you might want
to just put a landing on the concrete and work to that.


Either the first step will not have an even rise or the platform will not
have an even rise.


If you insist on having steps of a rise of 6 inches, you will have
a sneaker step which is too tall or too short. A tripping hazard.
My suggestion is to make a landing at the bottom which is level on
the top, with one side resting on the concrete and the other side is
supported two inches above the concrete.
Measure from the top of that landing to where the steps end. I.e,
25 - 1.25 (assuming 5/4 ply for the landing = 23.75" Divide that by
3,4,5,6, or however many steps you want to have. Now you have your
rise (7.9166, 5.9375", 4.75", 3.9583" respectively), Layout your
risers accordingly. I'd go for five steps, and do not forget to allow
for the thickness of the top step.



What's the point of the platform?


to provide a flat, level landing on the sloped slab. It will be
safer than having a "odd" riser. As the saying goes "the feet
remember" - a step which is off is a tripping hazard.

You could replace the slab, or put in a concrete landing so that
people will not be stepping down a different distance depending on
which side of the stairs they come down.
