13 would have had the attic sprinklered (assuming combustible construction).

But the roof framing should have been one hour protected above the decks or balconies.

We have had several fires like this in the Richmond area in the past decade. A fire started outside, burned up the outside wall and got into the attic. Once in the attic the trusses are great kindling and the whole building went up. Fortunately nobody has been killed yet. One of these days the roof is going to collapse on somebody who doesn't know there's a fire roaring overhead. Virginia now requires attics of apartments marketed to seniors to be sprinklered, but young folks are on their own.

Have you ever considered the possibility that no one has been killed because 13R systems do exactly what they were designed to do?
