What is the clearance required in a stairwell?

The required clearance in a stairwell typically depends on local building codes, but general guidelines suggest a minimum headroom of 6 feet 8 inches (about 2.03 meters) to ensure safe passage. Additionally, stair width should accommodate at least two people passing side by side, often around 36 inches (91 cm) or more. It's essential to consult local regulations for specific requirements, as they can vary by jurisdiction.
