Understanding NBC 2025 Classifications for Commercial and Industrial Spaces
The National Building Code of Canada (NBC) 2025 introduces refined criteria for classifying buildings to ensure fire safety and structural integrity. For businesses in London, Ontario, understanding these classifications is the first step toward a successful build or renovation. These classifications dictate everything from fire separation requirements to maximum building area.
Group D: Business and Personal Services Occupancies
Group D includes buildings used for the transaction of business or the rendering of professional or personal services. This category covers offices, banks, and medical clinics. Under the 2025 updates, there is an increased focus on energy efficiency and accessibility within these professional environments.
Group E: Mercantile Occupancies
Mercantile occupancies are defined as buildings used for the displaying or selling of retail goods, such as department stores, supermarkets, and shops. NBC 2025 emphasizes high-occupancy safety protocols and specific fire suppression systems tailored to the combustible load typically found in retail settings.
Group F: Industrial Occupancies
Industrial classifications are divided into three sub-sectors based on the level of hazard:
- Division 1 (High Hazard): Facilities involving highly flammable or explosive materials.
- Division 2 (Medium Hazard): Manufacturing and processing plants where combustible content is moderate.
- Division 3 (Low Hazard): Storage and workshops with low combustible content.
