HI,
I am taking the 120-hour licensing course for Florida and have a question about the Means of Egress course. It says the minimum tread depth on a staircase is 10". Is there a maximum allowed tread depth? I know I have encountered stairs that are really deep and require taking giant steps or baby steps to traverse them. Any thoughts?
Thanks.
Matt
I think in this paragraph, * Lighting is poor, shadows are numerous, or the corridor leading to the stairs is dark. It’s helpful to have a light switch installed at the top and bottom of each staircase. ( where the stairway has six or more risers.)
Welcome to our forum, Matt!..Enjoy!
There is no maximum tread depth, but there are minimum tread depths.
10" for residential and 11" for commercial.
Hope that helps.
