What is the minimum headroom clearance required for a stairway in a residential building?

  1. 1.9 meters

  2. 2.0 meters

  3. 2.1 meters

  4. 2.2 meters

The correct answer is: 2.0 meters

The minimum headroom clearance required for a stairway in a residential building is 2.0 meters. This is the standard clearance enforced by most building codes and safety regulations. Option A is incorrect because 1.9 meters is not enough space for average height individuals to comfortably walk up and down the stairs without ducking. Option C is incorrect because while 2.1 meters is slightly higher than the standard, it is not necessary and may result in wasted space. 2.2 meters, option D, is incorrect for the same reason as option C.
