Stair railing height

There are many regulations for staircase construction, some of them concerning stair railing height. These codes need to be followed as they are made for safety reasons.


The standards we know today have been set in 1991.

So, staircases build before this year may have hand-railings installed somewhere between 36 and 37 inches from the stair treads. Regulations from today refer to the high from the highest point and to the lower edge of the railing. Handrails need to be installed if the staircase’s height is larger than 30 inches.

Handrails installed after 1991 need to be installed at a minimum height of 36 inches from the top of the treads, and also need to not have any protruding edges that can cause injuries. Guard railings also need to conform to special regulations.
