Sarah's Expert Insight
OBC Compliance Specialist
"Navigating the 2024 OBC guard requirements is critical for multi-residential projects in London and custom builds in areas like Muskoka to ensure occupant safety and structural longevity. At empcontracting.ca Inc., your construction contractor in London, Ontario, we prioritize these load specifications to guarantee your balcony and window installations are both aesthetically pleasing and fully code-compliant."
When planning a residential or commercial build, ensuring the safety and structural integrity of guards and glazing is paramount. According to the 2024 Ontario Building Code (OBC), specifically sections 9.8.8.1 and 9.8.8.2, there are strict requirements for how glass and protective barriers are installed and tested.
OBC 9.8.8.1: Glazing Safety in Public Areas
In residential buildings of residential occupancy, glazing that extends to less than 1 metre from the floor and is located above the second storey must meet specific safety criteria. These installations must be:
- Protected by guards that comply with Subsection 9.8.8.
- Or, be non-openable and engineered to withstand lateral loads equivalent to those required for guards under Article 4.1.5.14.
Critical Load Requirements for Guards (9.8.8.2)
Guards must be designed to resist specific physical loads to prevent structural failure. The OBC outlines different requirements based on the location of the guard:
- Dwelling Units: Guards within houses or serving no more than two units must withstand a horizontal load of 0.5 kN/m or a concentrated load of 1.0 kN.
- Public Access Areas: Most other guards require a higher horizontal load resistance of 0.75 kN/m or a concentrated load of 1.0 kN.
- Vertical Loads: An evenly distributed vertical load of 1.5 kN/m must be applied at the top of the guard for all categories.
Compliance with Supplementary Standard SB-7
For housing and small buildings, the code provides a simplified path to compliance. Guards constructed in accordance with MMAH Supplementary Standard SB-7 are deemed to satisfy the core load requirements, offering a pre-approved method for builders to ensure safety.
