Los Angeles Building Code > 11A Housing Accessibility > 1115A Exterior Stairways > 1115A.6 Exterior Stairway Handrails
JUMP TO FULL CODE CHAPTER

1115A.6.1 Where Required

Stairways shall have handrails on each side. Intermediate handrails shall be located equidistant from the sides of the stairway and comply with Section 1012.9.

Exception: Stairways serving an individual dwelling unit may have one handrail, except that stairways open on one or both sides shall have handrails on the open side or sides.

1115A.6.2 Handrail Configuration

1115A.6.2.1 Handrail Heights

The top of handrails shall be 34 to 38 inches (864 to 965 mm) above the nosing of the treads.

1115A.6.2.2 Handrail Continuity

Handrails on all stairways shall be continuous within the full length of each stair flight. Inside handrails on switchback or dogleg stairs shall be continuous between stair flights.

1115A.6.2.3 Handrail Extensions

At the top of stair flights, handrails shall extend a minimum of 12 inches (305 mm) horizontally above landings, beginning directly above the first riser nosing. Extensions shall return to a wall, guard, or the walking surface, or shall be continuous to the handrail of an adjacent stair flight.

At the bottom of stair flights, handrails shall extend at the slope of the stair flight for a distance equal to one tread depth beyond the last riser nosing. Such extension shall continue with 12 inches (305 mm) minimum horizontal extension, shall be continuous to the handrail of an adjacent stair flight, or shall return to a wall, guard, or the walking surface. Handrail horizontal extensions shall be in the same direction as the stair flights. (See Figures 11A-6A and 11A-6E.)

1115A.6.2.4 Handrail Projections

Handrails projecting from a wall shall have a space of 11/2 inches (38.1 mm) minimum between the wall and the handrail.

Handrails may be located in a recess if the recess is a maximum of 3 inches (76.2 mm) deep and extends at least 18 inches (457 mm) above the top of the rail. Any wall or other surface adjacent to the handrail shall be free of sharp or abrasive elements. (See Figure 11A-6B.)

1115A.6.2.5 Handrail Gripping Surfaces

Handrail gripping surfaces shall be continuous along their length, and shall not be obstructed along their tops or sides. The bottoms of handrail gripping surfaces shall not be obstructed for more than 20 percent of their length. When provided, horizontal projections shall occur 11/2 inches (38.1 mm) minimum below the bottom of the handrail gripping surface. The distance between horizontal projections and the bottom of the gripping surface shall be permitted to be reduced by 1/8 inch (3.2 mm) for each 1/2 inch (12.7 mm) of additional handrail perimeter dimension that exceeds 4 inches (102 mm).

Handrail gripping surfaces and any surfaces adjacent to them shall be free of sharp or abrasive elements, and shall have rounded edges.

1115A.6.2.6 Cross Section

Handrail gripping surfaces shall comply with this section, or the shape shall provide equivalent gripping surface.

  1. Circular cross section. Handrail gripping surfaces with a circular cross section shall not be less than 11/4 inches (31.75 mm) nor more than 2 inches (50.8 mm) in cross-sectional dimension.
  2. Noncircular cross section. Handrail gripping surfaces with a noncircular cross section shall have a perimeter dimension of 4 inches (102 mm) minimum and 61/4 inches (159 mm) maximum, and a cross-section dimension of 21/4 inches (57 mm) maximum.

1115A.6.2.7 Fittings

Handrails shall not rotate within their fittings.
