Thank you

I believe it’s anymore than two.

Chad

Thank you.

Chad, do not forget that a railing is or can be the same height as a hand rail and needs to meet the 1&1/4" to 2" diameter grip size.
Jeff is correct as usual on his 4 risers or more for hand rail requirements.

Chad that would depend on your local jurisdiction. You should check with the National Building Code or your local building department.

I just noticed, Chad is a “Northerner.”

Listen to Raymond :smiley:

Chad
A couple of points. As Raymond stated always check with the local building dept. as they may have adopted something different. Also be careful when talking about steps, people talk about steps and codes will talk about risers.
There is always 1 more riser than treads (steps).

To get to your question - the code doesn’t refer to the exterior in steps but states from finished floor or platform to finished grade in excess of 30" requires a guard rail. It’s with interior they mention any stairway with more than 3 risers (2 steps) will require a handrail.

How would you interpret this configuration?

Is that piece of trim below the threshold a riser?
Would that constitute inconsistent riser height?
Does it require a rail?

Aaron

Yes the threshold would be considered a riser and would be inconsistent riser height. It has 4 risers so it should have a handrail on one side.

Pet peeve of mine is when someone answers a building question with: “I believe”. We are not dealing with a religious issue here. Your beliefs are not relevant. If you know the answer say so. If you don’t, then don’t answer. Leave it to someone who does.

Thanks my pet peeve is those member’s who do not go the top left control and fill in the information asked for .
