## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IBC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IBC 2009 Fire and Smoke Protection Features (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 17 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Building element is a defined term in the International Building Code (IBC) 2009, in Fire and Smoke Protection Features. The code's own words are: “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.” 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 17 chapters of this corpus, most often in Special Detailed Requirements Based on Use and Occupancy (IBC 2009), Fire and Smoke Protection Features (IBC 2009), Types of Construction (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## What must be verified before using this guidance?

**Building Element** is defined once in this corpus, in the [Fire and Smoke Protection Features](https://harth.build/resources/building-codes/us-states/maryland/ibc-2009/fire-and-smoke-protection-features.md) chapter of the International Building Code (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.

### The term in use

How the code actually writes about building element, quoted from the 2009 text hosted here:

> Where materials, systems or devices that have not been tested as part of a fire-resistance-rated assembly are incorporated into the building element, component or assembly, sufficient data shall be made available to the building official to show that the required fire-resistance rating is not reduced.

— [IBC 2009 §703.2](https://harth.build/resources/building-codes/us-states/maryland/ibc-2009/fire-and-smoke-protection-features.md)

> The path of egress travel along a means of egress shall not be interrupted by any building element other than a means of egress component as specified in this chapter.

— [IBC 2009 §1003.6](https://harth.build/resources/building-codes/us-states/maryland/ibc-2009/means-of-egress.md)


## The terms building element is built out of

The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what building element covers:

- **[Building](https://harth.build/resources/glossary/building.md)** — IBC 2009: Any structure used or intended for supporting or sheltering any use or occupancy.
- **[Listed](https://harth.build/resources/glossary/listed.md)** — IBC 2009: Equipment, materials, products or services included in a list published by an organization acceptable to the code official and concerned with evaluation of products or services that maintains periodic inspection of production of listed equipment or materials or periodic evaluation …

## Building Element: what to open, and in what order

Every row is a document this term depends on. The [ICC code library](https://codes.iccsafe.org/codes) and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) cover the middle rows.

| Check | Where | Confirmed |
| --- | --- | --- |

## Frequently asked questions

### What is the code definition of building element?

The International Building Code (IBC) 2009 defines it in Fire and Smoke Protection Features as: “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.” 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 building element?

In this corpus the term is used across 17 chapters, led by Special Detailed Requirements Based on Use and Occupancy 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 a building element?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Fire and Smoke Protection Features: “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.” 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 is the definition of a structure according to the building code?

Structure is a separate defined term. The IPC 2009 defines it as: “That which is built or constructed or a portion thereof.” That is not the same as building element, which the IBC 2009 defines as “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.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
