Determine when high-piled combustible storage permits are required under IFC Chapter 32, including the height trigger.

Steps

1. Confirm the core trigger: IFC Chapter 32 governs storage of combustible materials in closely packed piles, on pallets, in racks, or on shelves where the top of storage exceeds 12 feet in height
2. Confirm the lower threshold for high-hazard commodities: 6 feet, not 12 feet, for Class IV or high-hazard commodities as defined in Chapter 32
3. Confirm a permit is required per IFC Sections 105.6/105.7, and that plans/specifications must be submitted for review at time of building permit application (new construction) or at time of storage-permit application (change of use/existing building)
4. Note the locally adopted IFC edition matters — verify the specific edition (e.g., 2018, 2021, 2024) in force in the jurisdiction before citing chapter/section numbers, since numbering and thresholds can shift between editions
5. Recommend confirming commodity classification (Class I-IV, or high-hazard) early, since this drives both the height trigger and the required fire-protection design, not just the permit requirement itself
