Residential Stair Code

When it comes to residential stair standards, the International Residential

Code (IRC) establishes minimum requirements for stairs to insure a level of safety to the public. Several components are looked at such as stair width, headroom, riser and tread heights.

The International Residential Code (IRC) has specific instructions the way s

tairs can be built. Here’s a clear summary of what the IRC code says about stair rise, run and nosing.

Stairways in dwellings must be a minimum of 36 inches wide. The rise of ever

y residential step shall not exceed 7.75 inches and the tread depth shall not be less than 10 inches. The largest tread width or riser height within any flight of stairs shall not exceed the smallest by more than.375 inch measured at the walk line.

I received a question about stair width from one of our clients and thought

it made sense to clarify the typical stair design rules for houses. These are the rules that are in the 2006 International Residential Code. Stairways have to be at least 36″ clear width above the handrail height. Handrails can’t project more than 4.5″ into each side.

Every door must have, at a minimum, a floor area or landing with: (a) A widt

h not less than the width of the door or the width of the stairway served, whichever is greater; and (b) A length not less than thirty-six inches. (2) Stairways.
