To write those up as lacking ventilation would be in error.
As far as calling for every 150 square feet requiring 1 squre foot of ventilation I don't read that just because it is under 150 square feet it doesn't need any.
Exactly what I was pointing out. That ventilation/attic space is a ratio, not a bottom limit of attic space.
All based upon the code stating (underlining is mine) "
The total net free ventilating area shall not be less than 1/150 of the area of the space ventilated".
