I am trying to understand the fire-resistant rating to be applied to the exterior walls of two buildings.
I have a Type II-B F-1 occupancy building (1500sf) placed 5ft from a Type II-B F-2 occupancy building (1500sf). If I don't consider the two buildings as one per 503.1.2 then reading T 602 would require a 2 hr rated exterior wall on F-1 and a 1 hr rated exterior wall on F-2, correct? This is assuming that the imaginary lot line is halfway between the two buildings.
If I do consider the two buildings as one per 503.1.2 (well within T 503 allowables) and then read through Section 508, particularly 508.4, T 508.4 requires a 2 hr separation (NS). Am I interpreting this correct?
