Direct answer
Veneer is a defined term in the International Building Code (IBC) 2009, in Exterior Walls. The code's own words are: “A facing attached to a wall for the purpose of providing ornamentation, protection or insulation, but not counted as adding strength to the wall.” 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 24 chapters of this corpus, most often in Wall Covering (IRC 2009), Exterior Walls (IBC 2009), Wood (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.

The term in use
How the code actually writes about veneer, quoted from the 2009 text hosted here:
Interior masonry veneer shall comply with the requirements of Section R703.7.1 for support and Section R703.7.4 for anchorage, except an air space is not required.
The exterior wall envelope shall be designed and constructed in such a manner as to prevent the accumulation of water within the wall assembly by providing a water-resistive barrier behind the exterior veneer, as described in Section 1404.2, and a means for draining water that enters the assembly to the exterior.
In fire walls and fire barriers, unless treated to comply with Section 803.1 for Class A materials, the boards shall be cemented directly to the concrete, masonry or other noncombustible base and shall be protected with an approved noncombustible veneer anchored to the base without intervening airspaces.
The terms veneer is built out of
The definition above leans on 1 other defined term. Each carries its own code definition, and a local amendment to any of them changes what veneer covers:
- Facing — IRC 2009: The wood structural panel facings that form the two outmost rigid layers of the structural insulated panel.

Frequently asked questions
What is the code definition of veneer?
The International Building Code (IBC) 2009 defines it in Exterior Walls as: “A facing attached to a wall for the purpose of providing ornamentation, protection or insulation, but not counted as adding strength to the wall.” 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 veneer?
In this corpus the term is used across 24 chapters, led by Wall Covering in the IRC 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 does "veneer" mean?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Exterior Walls: “A facing attached to a wall for the purpose of providing ornamentation, protection or insulation, but not counted as adding strength to the wall.” 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.
