# Anchor Building: Building Code Definition > How the IBC 2009 define anchor building, where the wording differs, and which chapters depend on the term. - Canonical: https://harth.build/resources/glossary/anchor-building/ - Last updated: 2026-09-07 - Data source: Definitions quoted from the 2009 International Codes as transcribed in this site's building-codes collection, with the source chapter linked for each quotation. Usage counts are computed over the chapters hosted here, one copy per code. The [ICC code library](https://codes.iccsafe.org/codes) publishes the current model text and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) show which edition a jurisdiction has adopted; those sources control. ## Key facts | Fact | Value | | --- | --- | | Defined in | IBC 2009 (2009 editions transcribed in this corpus) | | Primary source | IBC 2009 Special Detailed Requirements Based on Use and Occupancy (model text, not a jurisdiction's adopted text) | | Chapters using the term | 4 (counted across the codes hosted here) | | Wording identical across codes | Single code (compare before citing one code's wording under another) | ## Direct answer Anchor building is a defined term in the International Building Code (IBC) 2009, in Special Detailed Requirements Based on Use and Occupancy. The code's own words are: “An exterior perimeter building of a group other than H having direct access to a coveredmall building but having required means of egress independent of the mall.” 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 4 chapters of this corpus, most often in Special Detailed Requirements Based on Use and Occupancy (IBC 2009), Fire and Smoke Protection Features (IBC 2009), Definitions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. *Content and cited inputs reviewed by [Scott Barrington](https://nz.linkedin.com/in/barrington), Harth founder and architectural technology specialist · Published 2026-09-07 · Updated 2026-09-07.* ## What does this term mean? **Anchor Building** — IBC 2009, Special Detailed Requirements Based on Use and Occupancy: > An exterior perimeter building of a group other than H having direct access to a coveredmall building but having required means of egress independent of the mall. ![Labeled code-term definition diagram: Anchor Building: Building Code Definition](https://efwwel0vyt9vy5so.public.blob.vercel-storage.com/images/glossary/anchor-building/diagram-1344.webp) *How the IBC 2009 define anchor building, where the wording differs, and which chapters depend on the term.* ## What must be verified before using this guidance? **Anchor Building** is defined once in this corpus, in the [Special Detailed Requirements Based on Use and Occupancy](https://harth.build/resources/building-codes/us-states/maryland/ibc-2009/special-detailed-requirements-based-on-use-and-occupancy.md) chapter of the International Building Code (IBC) 2009: > An exterior perimeter building of a group other than H having direct access to a coveredmall building but having required means of egress independent of the mall. ## Where anchor building is used in the code The term appears in 4 chapters of the 2009 I-Codes hosted here.

Each carries its own code definition, and a local amendment to any of them changes what anchor building covers: - **[Means OF Egress](https://harth.build/resources/glossary/means-of-egress.md)** — IBC 2009: A continuous and unobstructed path of vertical and horizontal egress travel from any occupied portion of a building or structure to a public way A means of egress consists of three separate and distinct parts: the exit access, the exit … - **[Building](https://harth.build/resources/glossary/building.md)** — IBC 2009: Any structure used or intended for supporting or sheltering any use or occupancy. ## Anchor Building: what to open, and in what order Every row is a document this term depends on.

The International Building Code (IBC) 2009 defines it in Special Detailed Requirements Based on Use and Occupancy as: “An exterior perimeter building of a group other than H having direct access to a coveredmall building but having required means of egress independent of the mall.” 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 anchor building? In this corpus the term is used across 4 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 does "anchor building" mean? In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Special Detailed Requirements Based on Use and Occupancy: “An exterior perimeter building of a group other than H having direct access to a coveredmall building but having required means of egress independent of the mall.” 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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fglossary%2Fanchor-building%2F - View this page in a browser: https://harth.build/resources/glossary/anchor-building/ - All resources for agents: https://harth.build/llms.txt
