Decoding Table 11.2.1.1.-K: Hazard Index for Mercantile Occupancies

When planning a commercial renovation or a change of use project in Ontario, understanding the Hazard Index (H.I.) for Group E (Mercantile) occupancies is essential. This index, as defined in the 2024 Building Code Compendium, determines the level of fire safety and structural requirements needed for your commercial space based on its size and use case.

Understanding Hazard Index (H.I.) Scaling

The Hazard Index is categorized into Small, Medium, and Large classifications. According to Table 11.2.1.1.-K, different retail environments carry varying degrees of risk. For example, large-scale Department Stores and Home Improvement Stores carry a high H.I. of 7, whereas smaller boutique operations like Bookstores or Flower Shops typically carry an H.I. of 3.
