I am working on two single family houses that are considered condominiums because of shared building lot, septic and well. The two buildings are attached by a shared storage room between them. The storage rooms are completely enclosed but not insulated and only accessible from the exterior. The distance from each building across the storage rooms is 10'. The drywall contractor has questioned if the walls adjoining the storage rooms should be fire rated.
The drawings by the architect don't show that any fire rating is required. I have asked them this question but have not yet received answer. Does the unfinished storage room between the two units make them attached and require a fire rated wall? Will we have to fire rate both exterior walls or only one? The exterior walls have 4" of foam on the exterior. Will installing 5/8 drywall over the foam cause issues with the fire rating?
Thanks,
