The requirement for handrails on spiral staircases may vary depending on local building codes and regulations. In many jurisdictions, handrails are required on both sides of a staircase if the staircase is wider than a certain measurement, typically around 44 inches (112 cm) or more. If the spiral staircase is narrower than this measurement, it may not necessarily require handrails. However, it is recommended to consult with local building authorities or professionals to determine the specific requirements and regulations applicable to your location.
