Direct answer
Bleachers is a defined term in the International Building Code (IBC) 2009, in Means of Egress. The code's own words are: “Tiered seating supported on a dedicated structural system and two or more rows high and is not a building element (see" Grandstands").” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 8 chapters of this corpus, most often in Means of Egress (IBC 2009), Means of Egress (IFC 2009), Accessibility (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 bleachers, quoted from the 2009 text hosted here:
Aisles serving reviewing stands, grandstands and bleachers shall also comply with Section 1028.
Bleachers, grandstands and folding and telescopic seating, that are not building elements, shall comply with ICC 300.
In theaters, bleachers, grandstands, stadiums, arenas and other fixed seating assembly areas, accessible wheelchair spaces complying with ICC A11 7.1 shall be provided in accordance with Sections 1108.2.2.1 through 1108.2.2.4.
Bleachers compared with Grandstand
These two are the closest pair in the 2009 I-Codes: about 90 per cent of their defining words are the same. The code states both and compares neither, so the difference is worth naming.
| Wording unique to it | |
|---|---|
| Bleachers (IBC 2009) | grandstands |
| Grandstand (IBC 2009) | bleachers |
Everything else in the two definitions is shared. If a project turns on which of the two applies, those words are the whole of the test — and a local amendment that edits one of them without editing the other moves the boundary between bleachers and grandstand.
The terms bleachers is built out of
The definition above leans on 3 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what bleachers covers:
- Building Element — IBC 2009: A fundamental component of building construction, listed in Table 601, which mayor may not be of fire-resistance-rated construction and is constructed of materials based on the building type of construction.
- Building — IBC 2009: Any structure used or intended for supporting or sheltering any use or occupancy.
- System — IFC 2009: An assembly of equipment consisting of a tank, container or containers, appurtenances, pumps, compressors and connecting piping.

Frequently asked questions
What is the code definition of bleachers?
The International Building Code (IBC) 2009 defines it in Means of Egress as: “Tiered seating supported on a dedicated structural system and two or more rows high and is not a building element (see" Grandstands").” 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 bleachers?
In this corpus the term is used across 8 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 is the definition of bleachers?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Means of Egress: “Tiered seating supported on a dedicated structural system and two or more rows high and is not a building element (see" Grandstands").” It is defined in IBC 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.
What does IBC mean in building codes?
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 bleachers, which the IBC 2009 defines as “Tiered seating supported on a dedicated structural system and two or more rows high and is not a building element (see" Grandstands").” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
