Final answer:
The minimum headroom required for a staircase is 6 feet 8 inches above each step and landing.
Step-by-step explanation:
In order to determine the minimum headroom required for a staircase, you need to consider the height of a person and the dimensions of each step. The International Building Code (IBC) recommends a minimum headroom height of 6 feet 8 inches (203 cm) above each step and landing. This height ensures that most people can comfortably walk up and down the stairs without hitting their heads.
To calculate the minimum headroom for a specific staircase, you would need to measure the vertical distance between each step and landing, and ensure it meets the IBC requirements.
