Brandon Whitmore Posted June 27, 2007 Report Share Posted June 27, 2007 From what I can gather from the IRC '03, the min. tread depth of a winder should be 6". The tread depth at this stairwell landing/ step is 5" against the railing. Judging from this pic-- am I justified in calling this out a inadequate tread depth, or am I missing something?

randynavarro Posted June 27, 2007 Report Share Posted June 27, 2007 Not looking at my stair book right now, but if I recall, you have to measure the tread depth from the centerof the step. IOW, if the stair is 36" wide, you measure the depth at 18" from the end of the step. Link to comment Share on other sites More sharing options...
charlie Posted June 27, 2007 Report Share Posted June 27, 2007 Where that winder tread meets the newel the minimum width is 6"-----I would say they missed by about 6" Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted June 27, 2007 Author Report Share Posted June 27, 2007 Randy, IRC says to measure 12" out I believe, but I also believe that the min. depth is 6" from what I am reading. Link to comment Share on other sites More sharing options...
