## Direct answer

Equipment platform is a defined term in the International Building Code (IBC) 2009, in General Building Heights and Areas. The code's own words are: “An unoccupied, elevated platform used exclusively for mechanical systems or industrial process equipment, including the associated elevated walk-ways, stairs, alternating tread devices and ladders necessary to access the platform (see Section 505.5).” The IFC 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 5 chapters of this corpus, most often in General Building Heights and Areas (IBC 2009), Definitions (IBC 2009), Means of Egress (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## The terms equipment platform is built out of

The definition above leans on 4 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what equipment platform covers:

- **[Mechanical Systems](https://harth.build/resources/glossary/mechanical-systems.md)** — IBC 2009: For the purposes of determining seismic loads in ASCE 7, mechanical systems shall include plumbing systems as specified therein.
- **[Equipment](https://harth.build/resources/glossary/equipment.md)** — IRC 2009: All piping, ducts, vents, control devices and other components of systems other than appliances that are permanently installed and integrated to provide control of environmental conditions for buildings.
- **[Building](https://harth.build/resources/glossary/building.md)** — IBC 2009: Any structure used or intended for supporting or sheltering any use or occupancy.

## Frequently asked questions

### What is the code definition of equipment platform?

The International Building Code (IBC) 2009 defines it in General Building Heights and Areas as: “An unoccupied, elevated platform used exclusively for mechanical systems or industrial process equipment, including the associated elevated walk-ways, stairs, alternating tread devices and ladders necessary to access the platform (see Section 505.5).” 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 equipment platform?

In this corpus the term is used across 5 chapters, led by General Building Heights and Areas 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 difference between a mezzanine and an equipment platform?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in General Building Heights and Areas: “An unoccupied, elevated platform used exclusively for mechanical systems or industrial process equipment, including the associated elevated walk-ways, stairs, alternating tread devices and ladders necessary to access the platform (see Section 505.5).” It is defined in IBC 2009, IFC 2009. It is not the same as Mezzanine, which the IBC 2009 defines separately as “An intermediate level or levels between the floor and ceiling of any story and in accordance with Section 505.” 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 IBC equipment platform requirements?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in General Building Heights and Areas: “An unoccupied, elevated platform used exclusively for mechanical systems or industrial process equipment, including the associated elevated walk-ways, stairs, alternating tread devices and ladders necessary to access the platform (see Section 505.5).” 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 is a platform in a building?

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 equipment platform, which the IBC 2009 defines as “An unoccupied, elevated platform used exclusively for mechanical systems or industrial process equipment, including the associated elevated walk-ways, stairs, alternating tread devices and ladders necessary to access the platform (see Section 505.5).” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
