Install railings on any deck that is 30 inches or more from the surrounding surface and on at least one side of a stairway leading to the deck. The top of the handrail should be at least 34 inches but not more than 38 inches high. The same height rules apply to stairs, and the inspector measures the handrail height from nose of the stair tread. The handrail, itself, should be easy to grip, with a minimum diameter of 1 1/4 inches and a maximum diameter of 2 1/4 inches.
Exterior stair railing code maintains that if your deck's stairs have fewer than two risers, a rail is not mandatory. On a related note, your deck must have guardrails or similar if it exceeds a height of 30 inches from the ground.
