The minimum height required for a handrail on a stairway in a residential building is set at 1050 mm according to the Ontario Building Code. This standard is crucial for safety, as it ensures that the handrail is high enough to effectively assist individuals in maintaining balance and support while using the stairs. A handrail at this height provides greater protection against falls, as it can be easily reached by individuals of different heights, including children and adults.

Maintaining a standardized height for handrails enhances accessibility and safety, particularly in residential buildings where the risk of falls can be significant. The height requirement helps ensure that the handrail can accommodate users in various circumstances, whether they are ascending or descending stairs, and helps facilitate ease of grip. Thus, having a handrail at a minimum height of 1050 mm is an integral aspect of building safety and design in residential properties.
