    We do a lot of projects that are sprinklered but still require separation of incidental uses with a 1 hour fire barrier, per 2018 IBC Section 509.

    NJ IBC - Fire Rating Between Townhomes

Per the exception though, membrane penetrations are allowed on the outside of the enclosure. Are you then allowed to run items inside the wall that...
