What is the minimum stairway width required for construction?

The minimum stairway width required for construction is typically set at 600 mm. This width is deemed adequate to ensure safe and efficient movement for individuals using the stairs. A width of 600 mm allows for two individuals to pass each other comfortably, which is particularly important in buildings with a high volume of foot traffic. Building codes often specify this minimum width as a means of accommodating emergency situations where quick evacuation may be necessary.

Wider stairways, while beneficial in certain high-traffic or public areas, are not required under typical building regulations unless specified for particular types of buildings or occupancy loads. Compliance with the code ensures that structures can adequately support their intended use while promoting safety and accessibility.
