Commercial Building Stairway Handrail Requirements: Safety & Regulations

In commercial buildings, handrails are required on both sides of a stairway when:

1. The stairway has four or more risers.
2. The stairway is open on one or both sides.
3. The stairway is in a public area (e.g., lobby, hallway).
4. The stairway is used by non-employees (customers, visitors).

These regulations aim to reduce slips, trips, and falls by providing support and stability for all users.
