Are open risers alright at outside steps and stairs?
Wednesday, March 10, 2021
Open risers are acceptable on short stair runs where it is 30-inches or less to the ground. So the open risers on the stairs to the low deck shown above are acceptable. But when stairs go higher, like in the photo below, the International Residential Code (IRC 1011.5.5.3) allows open risers only as long as “the opening between the treads does not permit the passage of a 4-inch diameter sphere.”
Although the code does not differentiate between requirements for interior and exterior stairs, we rarely call out open risers on interior stairs, but see them regularly at exterior stairs to wood decks and porches.
