Can the 60" clear length of a ramp landing (ICC A117.1-2009, section 405.7.3) have a door swing over it?
Section 405.7.5 says "where doorways are adjacent to a ramp landing", and then the commentary says "...doors are permitted only adjacent to the ramp and not adjacent to or on the ramp itself." Does this phrase actually prohibit the door arc to pass over the 60" clear length? - it sounds to me like it's just prohibiting the door from swinging over the ramp, not the landing's clear area? The commentary figure c405.7.5(a) shows the landing outside the arc, but I don't see that in the language directly- just implied, by saying what can overlap the landing it implies any other things can't overlap? Further, the commentary references "Section 404.2.4.5", which doesn't exist. Can someone point me to errata? I'm having trouble finding it.
There is then a figure 1012.5.3 in the 2015 IBC commentary, where it shows a door arc over the 60" landing, and just required 42" clear, measured to the railings though- not to the start of the ramp.
Also figure 1012.2 in the 2015 IBC commentary, shows a door opening over a ramp landing, and just required 42" outside the arc, seems to be ok that the door swings over that landing?
