8 - Exterior Stairs: Uneven steps are a trip hazard which should be corrected. The difference in the distance between one step and another should be no greater than 3/8 inch. Handrails should be secure and have a grippable surface. Two by four inch or two by six inch boards are not considered appropriate for handrails unless they are routed with a grip. Current standards call for narrow clearances between rails such that a 4 inch sphere may not pass through. Older rails had larger openings when installed and upgrading should be considered for child safety.
