Direct answer
Congregate living facilities is a defined term in the International Building Code (IBC) 2009, in Use and Occupancy Classification. The code's own words are: “A building or part thereof that contains sleeping units where residents share bathroom and/or kitchen facilities.” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 3 chapters of this corpus, most often in Definitions (IFC 2009), Use and Occupancy Classification (IBC 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 congregate living facilities?
The International Building Code (IBC) 2009 defines it in Use and Occupancy Classification as: “A building or part thereof that contains sleeping units where residents share bathroom and/or kitchen facilities.” 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 congregate living facilities?
In this corpus the term is used across 3 chapters, led by Definitions in the IFC 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 the definition of a congregate living facility?
Facility is a separate defined term. The IBC 2009 defines it as: “All or any portion of buildings, structures, site improvements, elements and pedestrian or vehicular routes located on a site.” That is not the same as congregate living facilities, which the IBC 2009 defines as “A building or part thereof that contains sleeping units where residents share bathroom and/or kitchen facilities.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
