I've got an existing building with a manual front main entrance door, which is lacking the required 18" clearance (seen in table 404.2.3.2, ICC A117.1-2009) for front approach from pull side. In considering installing an automatic door, I see 404.3.2 requiring them to return to section 404.2.3 for maneuvering clearances. Since table 404.2.3.2 specifies it's for manual swinging doors, does this mean the automatic door here doesn't need the 18" clearance? For the control switch, it says it must be 'beyond the arc of the door swing', is there any other location requirements, aside from the usual reach areas for a button?
