What is the standard rise in stair design for a dwelling unit, stated in millimeters?

In residential building design, the standard rise for stair treads is crucial for ensuring safety and comfort when navigating stairs. The rise is defined as the vertical distance between the top of one step and the top of the next. According to the BC Building Code and common industry standards, the maximum rise for staircases is typically set at 200 mm. This standard is established to promote user-friendly access and minimize tripping hazards, as steeper rises can lead to accidents and discomfort.

When crafting stair designs, adhering to this standard rise helps builders and designers create stairs that are not only compliant with building regulations but also enhance the overall functionality of a dwelling. It provides a dependable guideline for the construction of safe and stable stairways within residential units, ensuring that they meet the needs of the occupants.

Thus, the choice of 200 mm as the standard rise in stair design for a dwelling unit aligns with established building practices, supporting the development of stair systems that are both practical and within safety parameters.
