Hand rail height
 
I am finishing my basement and will be adding a hand rail to the stairs leading down. What height does the rail need to be off the stairs?

Check your local building code.
but typically 32" - 36" plumbed of the nosing of the tread

We go for 900 of those mm thingies, so that would be 36" in your part of the world :thumbsup:

Incidentally, it is higher for handrails on a balcony (1100mm or 431/4 ish), seen too many balconies with big drops with dangerous 36" handrails on DIY jobs!

IBC Section 1012 Handrails

1012.2 Height. Handrail height, measured above stair tread nosings, or finish surface of ramp slope shall be uniform, mot less than 34 inches (864 mm) and not more than 38 inches (965 mm).

Mezzanine or balcony has to be not less than 42 inches (1067 mm).

Partially correct. However, the IBC is the code that covers commercial and multifamily structures, not usually single family residences. Nearly all jurisdictions that adopt the I-codes adopt the IRC, which is the residential code. The 42" number does not exist in that code....It is 36". Of course a guard that is 42" is taller and would be acceptable, albeit unusual in a home.

Agreed, the top of the handrail's profile should be 34-38" above the plane of the nosings of the treads. There are a hundred ways to incorrectly measure this. Aim for 36" and you'll probably be good.

Here is a link to an EXCELLENT visual resource that shows how stairs and handrails should be measured and how code should be applied. Just select whichever code edition applies in your area. It is a free download.

Thanks for the link, its great! I wish that there was something like that to cover all aspects of a build.

It's interesting to look at the differences, we don't have to return handrails at the end, in the UK.

One to book mark for reference in case of a 'difficult' customer!

Very true, not only as point of accuracy, but great difference in the asthetics of the rail. I have bumped up to 38" a few times when customers wanted a bit extra height for younger kids and it still looked ok; but a 42" balcony rail in a house is absurred looking IMO.

Thanks everyone... 36" sound good to me.. This is a enclosed staircase.
