I suggest a careful reading of 6.6.6 in 13R. While a 13D system ignores storage in attics, 13R does not allow the same considerations.
Appropriately, I think Todd means, if the area becomes a “Story” or not as defined in IBC. Then it would be treated like a dwelling unit. Otherwise, you are running into an area outside the dwelling unit and get kicked back to 13 for Design. My observation on limited data. R/ Matt Matthew J. Willis, CWBSP, C.E.T.

When you say " it would need to be appropriately protected" do you mean the attic would need to be sprinklered? It would become accessible to the tenant and they would likely use it for storage. Does 13R allow omission of sprinklers only for attics not used for storage?

However, since it is accessible for living space or storage, it would need to be appropriately protected. Even then, it could be considered 4 stories instead of 3 and it would still be 13R.

We designed the system to NFPA 13R, with no sprinklers in the attic. Now the architect wants to add access to the attic for the 3'rd floor tenant. (note, there's only one tenant on the 3rd fl. of this building) My question is, can the architect actually allow access to the attic for a tenant in a multifamily as far as the building or fire codes are concerned? If yes, would sprinklers be required in the attic in this case? (considering tenant will likely use it as storage) Thanks _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org<https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org> To unsubscribe send an email to sprinklerforum-le...@lists.firesprinkler.org<mailto:sprinklerforum-le...@lists.firesprinkler.org> _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org<https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org> To unsubscribe send an email to sprinklerforum-le...@lists.firesprinkler.org<mailto:sprinklerforum-le...@lists.firesprinkler.org>
