I get that. Different in form and the same in function. Both serve as a way out of the building. When sauntering out the means of egress on your way to the hairdresser you are precluded from passing through a garage......when fleeing from danger all bets are off?
Insight to the reasoning the committee applied to the ban on an egress through a garage would be helpful. It could be that it just sounded great so they did it.
I met a member of the code making committee that established fifty occupants as a trigger for egress requirements. I asked what evidence was presented to validate the number. I was told that there is no science behind it. Some on the panel wanted twenty and some wanted 120. Fifty is a number that all of the members could agree with.
Other than the fact that TBird's goose is getting roasted, this could be a pointless discussion.
Oh and BIG T...........try not being mean to my friends.
I read the code as not wanting the garage to be the only egress provided for the dwelling. For EERO the more the better, ideally.
