What are the Requirements for Design of Stairways Used During Construction in California?

According to the California Code of Regulations, the requirements for the design of stairways used during construction are as specified: 

• Temporary stairways used during construction (not meant to remain a permanent part of the property) are also required to be 24 inches in width and must have landings at each floor, or level, of at least 30 inches deep (in the direction of travel) and 24 inches wide at every 12 feet (3.7 m) or less of vertical rise. Workers must not use spiral, temporary stairways on location. 
• The stairways must be installed between 30 degrees to 50 degrees from horizontal. 
• The riser height and tread depth must be the same within each flight of stairs, and should not exceed 1/4 inch (0.6 cm). 
• If a stairway is placed near a door or gate opening, the stairway must have a platform between the swing of the door and the stairs of no less than 20 inches (51 cm).
• All sides of the stairway must have railings. 
• Metal pan landings and metal pan treads must be secured in place before filling with concrete, or any other fortifying material. 
• The stairway must be free of dangerous, hazardous objects ( ex. jutting nails). In addition, if the stairway is slippery, this condition must be fixed before its usage.  

What are the California Regulations for Stair Rails and Hand Rails?

The following general requirements by the California Code of Regulations apply to all stair rails and hand rails:

• A stairway with four or more risers, or rising more than 30 inches (76 cm), must be fortified with: one handrail (minimum requirement) and a stair rail, top rail, and mid-rail, along each unprotected side. The stair rails and hand rails should be incorporated as to prevent injuries of the employees, provide an adequate handhold, and prevent the tearing of clothing; or any other punctures or lacerations. In addition, the stair rails, handrails and mid-rails must be constructed so as not to create hazard.
• Handrails and top rails of the stairs must be able to endure, clearly without failure, at least 200 pounds (890 n) of weight when applied within 2 inches (5 cm) of the top in any downward or outward direction, at any point along the top edge.
• The height of the stair rails should not be less than 34 inches and should not exceed 38 inches from the upper surface to the tread.  
• In the case that the top edge of the stair also serves as a handrail, the height should be at least 34 inches, and no more than 38 inches from the upper surface of the stair rail to the surface of the tread.
• Mid-rails should preferably be located at a height midway between the top edge of the stair rail and the stairway steps. In addition, when materials such as screens, mesh, or others used in mid-rails, they are required to extend from the top rail to the stairway step; ensuring that there are no openings in the stair rail of more than 18 inches (46 cm) wide.
• In the case of spiral and winding stairways, these must be equipped with a handrail to prevent walking on areas were the tread width is less than 6 inches (15 cm). 
• If a handrail has been placed as part of a temporary structure, it must have a minimum clearance of 3 inches (8 cm) between the handrail and walls, stair rails, and other objects.

California Regulations for Temporary Service of Stairways

The California Code of Regulations also describes the temporary service of stairways. The following are to be monitored at all times, except during stairway construction. 

• Individuals must stay off the stairway with pan stairs where the treads and/or landings are to be filled with concrete or other material.
• Individuals must stay off the ‘skeleton’ of the stairway, such as metal stairs, where the permanent treads/landings are to be installed, unless the stairs are to be secured temporarily with solid material long enough to cover the entire skeleton area. 
• In addition treads for temporary usage must be made of wood or any other solid material that will withstand weight, and cover the full width and depth of the stair. These must also be replaced when needed (usually below the level of the top edge of the pan).
