I could only find one building code that
mentioned using the top of the guard railing as a gripable
handrail. The top of the gripable handrail would need to be
between 36 and 38 inches in height, measuring from the stair
tread nosing.
This particular building code only applies to a private stairway
or individual residents. However, I only found this in one
building code book. Whatever you do, make sure that you check
with your local Building and Safety Department, before even
thinking about using this building code.
Special Note: This home was built around 2007.
This house is another example of how each individual Building
and Safety Department, interprets the building code books. Most
building code books clearly state that a stairway is required to
have a 42 inch protective guard railing and a continuous
gripable handrail.
The 1997 Uniform Building Code Book section 509.2
provides an exemption for Group R, Division 3 and Group U
occupancies. Interior guardrails within individual dwellings may
be 36 inches (instead of 42 inches). This building code is
obviously old, but I don't know if it's outdated. Only your
local Building and Safety Department can verify these building
codes.
