Note: ShedSafe and SMS do NOT support Class 2 Buildings 

Overview

This article explains what Class 2 buildings are and clarifies that ShedSafe and SMS do not support this building classification.

Why This Is Important

  • Avoids compliance issues with the National Construction Code (NCC).
  • Helps direct customers toward appropriate solutions for Class 2 buildings.

What Are Class 2 Buildings?

  • Class 2 buildings are apartment buildings, typically multi-unit residential structures where people live above and below each other.
  • According to the NCC, the apartment spaces are referred to as sole-occupancy units (SOUs).

Examples of Class 2 Configurations

  • Multi-storey apartment complexes.
  • Single-storey attached dwellings with a common space below, such as:
    • Two dwellings above a shared basement.
    • Apartments over a carpark.

Important Note

🚫 ShedSafe and SMS do NOT support Class 2 buildings.

Any enquiries or projects involving Class 2 classifications should be directed to an appropriate engineering or architectural firm experienced in apartment building design.

Tips, Best Practices & Troubleshooting

  • Confirm the intended building class before starting a quote.
  • If a project includes residential units above or below each other, it is likely Class 2.
  • Always advise customers early that these designs are not supported by SteelX systems.
  • For guidance, refer to the NCC or consult an accredited certifier.
