Direct answer
Decorative glass is a defined term in the International Building Code (IBC) 2009, in Glass and Glazing. The code's own words are: “A carved, leaded or DaIle glass or glazing material whose purpose is decorative or artistic, not functional; whose coloring, texture or other design qualities or components cannot be removed without destroying the glazing material and whose surface, or assembly into which it is incorporated, is divided into segments.” The IRC 2009 defines the same term with different wording, so the controlling text depends on which code governs the question in front of you — the comparison below sets the versions side by side. The term is used in 3 chapters of this corpus, most often in Glass and Glazing (IBC 2009), Definitions (IBC 2009), Definitions (IRC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

Frequently asked questions
What is the code definition of decorative glass?
The International Building Code (IBC) 2009 defines it in Glass and Glazing as: “A carved, leaded or DaIle glass or glazing material whose purpose is decorative or artistic, not functional; whose coloring, texture or other design qualities or components cannot be removed without destroying the glazing material and whose surface, or assembly into which it is incorporated, is divided into segments.” 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 decorative glass?
In this corpus the term is used across 3 chapters, led by Glass and Glazing 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 decorative glass?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Glass and Glazing: “A carved, leaded or DaIle glass or glazing material whose purpose is decorative or artistic, not functional; whose coloring, texture or other design qualities or components cannot be removed without destroying the glazing material and whose surface, or assembly into which it is incorporated, is divided into segments.” It is defined in IBC 2009, IRC 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 requirements for tempered glass in the International 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 decorative glass, which the IBC 2009 defines as “A carved, leaded or DaIle glass or glazing material whose purpose is decorative or artistic, not functional; whose coloring, texture or other design qualities or components cannot be removed without destroying the glazing material and whose surface, or assembly into …” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
