Is this a breach of firewall

This is in the garage of a new home, It is a crawlspace access. Is it a breach of firewall?

If I understand your post correctly… YES, it is.

Yes. I call out crawl hatches that are not fire rated in the garage. All surfaces adjacent to the living area need to be fire rated.

i thought so

Just to play devil’s advocate…

How thick was the subfloor and if it is 1 3/8 inches, would it be any different than the fire door of the same thickness?

Looks thinner

I agree Bob. It only looks like 3/4 inch but it was just for discussion.

So, now do you have the answer to your first question? Just curious the answer.:wink:
