What is the minimum height required for a guardrail on a balcony in a residential building?

1. 0.9 meters

2. 1.0 meter

3. 1.1 meters

4. 1.2 meters

The correct answer is: 1.1 meters

In residential buildings, the Ontario Building Code specifies that the minimum height for guardrails on a balcony must be 1.0 meter. This standard is established to enhance safety by preventing falls from elevated areas, ensuring a secure environment for residents and visitors. The height requirement reflects considerations regarding the typical age group of occupants and the potential for various activities on the balcony that may increase the risk of falls. The choice of 1.0 meter aligns with established safety practices in building design and is deemed sufficient to provide an effective barrier against falls. Compliance with this regulation is important for ensuring the structural integrity and user safety of outdoor spaces within residential settings.
