Direct answer
Circulation path is a defined term in the International Building Code (IBC) 2009, in Accessibility. The code's own words are: “An exterior or interior way of passage from one place to another for pedestrians.” No other I-Code in this corpus defines it, so the IBC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in Accessibility (IBC 2009), Duct Systems (IMC 2009), Definitions (IBC 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 circulation path?
The International Building Code (IBC) 2009 defines it in Accessibility as: “An exterior or interior way of passage from one place to another for pedestrians.” 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.
Which parts of the code depend on circulation path?
In this corpus the term is used across 3 chapters, led by Accessibility 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 is considered a circulation path?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Accessibility: “An exterior or interior way of passage from one place to another for pedestrians.” It is defined in IBC 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.
What are the key components of a building code?
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 circulation path, which the IBC 2009 defines as “An exterior or interior way of passage from one place to another for pedestrians.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
