Exterior Wall Opening Protection 705.8

[Gutt Mcdonald]

Hey! I have a general question re IBC section 705.8.
Do these wall openings regulate all portions of an exterior wall- even if they dont need to be rated?
Say for example I have an exterior wall in a building- type VB construction- with a FSD of 15' to an existing building on the same lot.
Per 705.5 The wall would not need to be rated. Do I need to still comply with opening protectives of 75% of the wall opening per 705.8?
