How does this exception work or apply by not having a gable vent?

Without the gable vent there is one less place for the fire to spread to neighboring buildings?

Vinyl soffit is an excellent substitute for 1hr construction...

I was taught to never put an eave vent over a window.

That seems very difficult, considering the random location with windows, aligning with the regularity of vent placement.ICE said:I was taught to never put an eave vent over a window.

There is no set pattern required for eave vents that I am aware of. If you lose a few here and there what's the big deal? Just add a few somewhere else.

Rules of thumb. There are some good ones out there, and some bad ones...

Clarification from the 2018 IRC changes "eave" with the following:
b. The fire-resistance rating shall be permitted to be reduced to 0 hours on the underside of the rake overhang where gable vent openings are not installed.
