Comment: In the first sentence, it states that the National Building Code sets a minimum unit run as 210mm for private stairs. In the 2015 National Building Code in Table 18.104.22.168. it states a minimum unit run for private stairs as 255 mm. My question is, in the Apprenticeship exam for Level 2 carpentry, which figure is used? Would it be possible in the future, to specify which version of the NBC is being used in the modules because some of the information seems to have been updated while other has not which is cause for confusion. Thank you.
