Direct answer
Handrail is a defined term in the International Building Code (IBC) 2009, in Means of Egress. The code's own words are: “A horizontal or sloping rail intended for grasping by the hand for guidance or support.” The IRC 2009, IFC 2009 carry the same definition word for word, so the term means the same thing in each. The term is used in 14 chapters of this corpus, most often in Means of Egress (IBC 2009), Means of Egress (IFC 2009), Building Planning (IRC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

Frequently asked questions
What is the code definition of handrail?
The International Building Code (IBC) 2009 defines it in Means of Egress as: “A horizontal or sloping rail intended for grasping by the hand for guidance or support.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.
Do the I-Codes define handrail the same way?
In the 2009 editions transcribed here, yes: IBC 2009, IRC 2009, IFC 2009 carry the same wording, so the term means the same thing in each. Later editions do diverge on some terms, so confirm against the adopted edition rather than assuming the alignment holds.
Which parts of the code depend on handrail?
In this corpus the term is used across 14 chapters, led by Means of Egress in the IBC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.
What are the building code requirements for handrails?
Building is a separate defined term. The IBC 2009 defines it as: “Any structure used or intended for supporting or sheltering any use or occupancy.” That is not the same as handrail, which the IBC 2009 defines as “A horizontal or sloping rail intended for grasping by the hand for guidance or support.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
What are common handrail code violations?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Means of Egress: “A horizontal or sloping rail intended for grasping by the hand for guidance or support.” It is defined in IBC 2009, IRC 2009, IFC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
