Bleachers and Unlimited Area buildings.

[steveray]

The bleachers, as currently planned, are considered an obstruction within the 60-foot boundary established by the unlimited area building.
Both the AHJ and fire dept are going by the book (and definitions) of the building code and concurred.
Interestingly, the row of tress planned within the 60-foot boundary were OK. (I'm guessing because trees not "buildings/structures"?)

Changing the Type of Construction to IB is not feasible. Neither is providing a 3-hour rated wall along the reduced area.

As a "Hail Mary", i proposed using Section 503.1.2 Buildings on the Same Lot, and the AHJ was seemed agreeable to the approach.

I've never worked on a project using this provision in the Code.
Should I be skeptical that this is the correct approach?

This is ridiculous...If you can call it 2 "buildings" on the same lot, then you can call it one UA building as long as construction type works....
