I'm not entirely sure how the second tower could be considered not a high rise. The highest occupied floor is 124' or so above the fire department access. I was told it wasn't a high rise during kickoff, but we may have been given incorrect information. After talking to the architect, the AHJ is considering it all one building anyway. So that puts that to rest.
