When are graspable handrails required?

Continuously graspable handrails are required on stairs with four or more risers and mounted between 34 and 38 inches of the stair slope and not less than 1 1/2 inches from the wall. One-and-two family dwellings require one graspable handrail while Commercial and multi-family buildings require handrails on both sides. Many exterior plastic composite handrails meet these requirements.
