High-Pile Combustible Storage Permit Requirements

According to the International Fire Code (IFC) 2021, Section 105.6.23, a permit is required for the storage of high-pile combustible stock when the storage area exceeds 2,500 square feet.

2. Definition of High-Pile Storage

High-pile storage is defined as storage of combustible materials on racks or piles exceeding 12 feet in height (or 6 feet for highly combustible materials, such as rubber and plastics).

IFC Table 3206.2 establishes fire protection requirements based on storage height, area, and commodity class.

3. Verification of Other Options

Option A (225 sq. ft.) – Incorrect, as this is far below the 2,500 sq. ft. permit threshold.

Option B (500 sq. ft.) – Incorrect, as the fire code does not require a permit at this level.

Option C (1,000 sq. ft.) – Incorrect, as the IFC specifies 2,500 sq. ft. as the threshold for requiring a permit.
