R311.5 Stairways.
R311.5.1 Width. Stairways shall not be less than 36 inches
(914 mm) in clear width at all points above the permitted
handrail height and below the required headroom height.
Handrails shall not project more than 4.5 inches (114 mm.)
on either side of the stairway and the minimum clear width
of the stairway at and below the handrail height, including
treads and landings, shall not be less than 31.5 inches (787
mm) where a handrail is installed on one side and 27 inches
(698 mm) where handrails are provided on both sides.
Exception: The width of spiral stairways shall be in
accordance with Section R311.5.8.
R311.5.2 Headroom. The minimum headroom in all parts
of the stairway shall not be less than 6 feet 8 inches (2036
mm) measured vertically from the sloped plane adjoining
the tread nosing or from the floor surface of the landing or
platform.
R311.5.3 Stair treads and risers.
R311.5.3.1 Riser height. The maximum riser height
shall be 73/4 inches (196 mm). The riser shall be mea-
sured vertically between leading edges of the adjacent
treads. The greatest riser height within any flight of stairs
shall not exceed the smallest by more than 3/8 inch (9.5
mm).
R311.5.3.2 Tread depth. The minimum tread depth
shall be 10 inches (254 mm.). The tread depth shall be
measured horizontally between the vertical planes of the
foremost projection of adjacent treads and at a right
angle to the tread's leading edge. The greatest tread depth
within any flight of stairs shall not exceed the smallest by
more than inch (9.5 mm.). Winder treads shall have a
minimum tread depth of 10 inches (254 mm) measured
as above at a point 12 inches (305 mm) from the side
where the treads are narrower. Winder treads shall have a
minimum tread depth of 6 inches (152 mm) at any point.
Within any flight of stairs, the largest winder tread depth
at the 12 inch (305 ram) walk line shall not exceed the
smallest by more than 3/8 inch (9.5 mm).
R311.5.3.3 Profile. The radius of curvature at the lead-
ing edge of the tread shall be no greater than 9/16 inch (14
mm.). A nosing not less than 3/4 inch (19 mm) but not
more than 1'/4 inch (32 nun) shall be provided on stair-
ways with solid risers. The greatest nosing projection
shall not exceed the smallest nosing projection by more
than 3/8 inch (9.5 mm) between two stories, including
the nosing at the level of floors and landings. Beveling
of nosing shall not exceed '/2 inch (12.7 mm). Risers
shall be vertical or sloped from the underside of the
leading edge of the tread above at an angle not more
than 30 degrees (0.51 rad) from the vertical. Open risers
are permitted, provided that the opening between treads
does not permit the passage of a 4-inch diameter (102
mm.) sphere.
Exceptions:
1. A nosing is not required where the tread depth
is a minimum of 11 inches (279 mm).
2. The opening between adjacent treads is not lim-
ited on stairs with a total rise of 30 inches (762
mm) or less.
R311.5.4 Landings for stairways. There shall be a floor or
landing at the top and bottom of each stairway.
Exception: A floor or landing is not required at the top of

A flight of stairs shall not have a vertical rise larger than
12 feet (3658 mm) between floor levels or landings.
The width of each landing shall not be less than the width
of the stairway served. Every landing shall have a minimum
dimension of 36 inches (914 mm) measured in the direction
of travel.
R311.5.5 Stairway walking surface. The walking surface

one side of each continuous run of treads or flight with four
or more risers.
R311.5.6.1 Height. Handrail height, measured verti-
cally from the sloped plane adjoining the tread nosing, or
finish surface of ramp slope, shall be not less than 34
inches (864 mm) and not more than 38 inches (965 nun).
R311.5.6.2 Continuity. Handrails for stairways shall be
continuous for the full length of the flight, -from a point
directly above the top riser of the flight to a point directly
above the lowest riser of the flight. Handrail ends shall be
returned or shall terminate in newel posts or safety termi-
nals. Handrails adjacent to a wall shall have a space of not
less than 1'/z inch (38 mm) between the wall and the
handrails.
Exceptions:
