Introduction
The International Building Code® (IBC®) establishes minimum requirements for building systems using
prescriptive and performance-related provisions. It is founded on broad-based principles that make
possible the use of new materials and new building designs. This 2021 edition is fully compatible with
all of the International Codes® (I-Codes®) published by the International Code Council® (ICC®), including the International Energy Conservation Code® (IECC®), International Existing Building Code® (IEBC®),
International Fire Code® (IFC®), International Fuel Gas Code® (IFGC®), International Green Construction
Code® (IgCC®), International Mechanical Code® (IMC®), International Plumbing Code® (IPC®), International Private Sewage Disposal Code® (IPSDC®), International Property Maintenance Code® (IPMC®),
International Residential Code® (IRC®), International Swimming Pool and Spa Code® (ISPSC®), International Wildland-Urban Interface Code® (IWUIC®), International Zoning Code® (IZC®) and International
Code Council Performance Code® (ICCPC®).
In addition to the codes themselves, the code development process brings together building professionals on a regular basis. It provides an international forum for discussion and deliberation about
building design, construction methods, safety, performance requirements, technological advances
and innovative products.
The I-Codes, including the IBC, are used in a variety of ways in both the public and private sectors.
Most industry professionals are familiar with the I-Codes as the basis of laws and regulations in communities across the US and in other countries. However, the impact of the codes extends well beyond
the regulatory arena, as they are used in a variety of nonregulatory settings, including:
• Voluntary compliance programs such as those promoting sustainability, energy efficiency and
disaster resistance.
• The insurance industry, to estimate and manage risk, and as a tool in underwriting and rate
decisions.
• Certification and credentialing of individuals involved in the fields of building design, construction and safety.
• Certification of building and construction-related products.
• US federal agencies, to guide construction in an array of government-owned properties.
• Facilities management.
• “Best practices” benchmarks for designers and builders, including those who are engaged in
projects in jurisdictions that do not have a formal regulatory system or a governmental
enforcement mechanism.
• College, university and professional school textbooks and curricula.
• Reference works related to building design and construction.
In addition to the codes themselves, the code development process brings together building professionals on a regular basis. It provides an international forum for discussion and deliberation about

This 2021 edition presents the code as originally issued, with changes reflected in the 2003 through
2018 editions and further changes approved by the ICC Code Development Process through 2019. A
new edition such as this is promulgated every 3 years.
This code is intended to establish provisions that adequately protect public health, safety and welfare; that do not unnecessarily increase construction costs; that do not restrict the use of new materials, products or methods of construction; and that do not give preferential treatment to particular
types or classes of materials, products or methods of construction.

2021 INTERNATIONAL BUILDING CODE® iv Maintenance
The IBC is kept up to date through the review of proposed changes submitted by code enforcement
officials, industry representatives, design professionals and other interested parties. Proposed
changes are carefully considered through an open code development process in which all interested
and affected parties may participate.
The ICC Code Development Process reflects principles of openness, transparency, balance, due process and consensus, the principles embodied in OMB Circular A-119, which governs the federal government’s use of private-sector standards. The ICC process is open to anyone; there is no cost to participate,
and people can participate without travel cost through the ICC’s cloud-based app, cdpAccess®. A broad
cross section of interests are represented in the ICC Code Development Process. The codes, which are
updated regularly, include safeguards that allow for emergency action when required for health and
safety reasons.
In order to ensure that organizations with a direct and material interest in the codes have a voice in
the process, the ICC has developed partnerships with key industry segments that support the ICC’s
important public safety mission. Some code development committee members were nominated by
the following industry partners and approved by the ICC Board:
• American Institute of Architects (AIA)
• National Association of Home Builders (NAHB)
• National Association of State Fire Marshals (NASFM)
The code development committees evaluate and make recommendations regarding proposed
changes to the codes. Their recommendations are then subject to public comment and council-wide
votes. The ICC’s governmental members—public safety officials who have no financial or business
interest in the outcome—cast the final votes on proposed changes.
The contents of this work are subject to change through the code development cycles and by any
governmental entity that enacts the code into law. For more information regarding the code development process, contact the Codes and Standards Development Department of the ICC.
While the I-Code development procedure is thorough and comprehensive, the ICC, its members
and those participating in the development of the codes disclaim any liability resulting from the publication or use of the I-Codes, or from compliance or noncompliance with their provisions. The ICC does
not have the power or authority to police or enforce compliance with the contents of this code.
IBC Primary Code Development Committees
In each code development cycle, code change proposals to this code are considered at the Committee
Action Hearings by 11 different code development committees. Four of these committees have primary responsibility for designated chapters and appendices as shown in the following table: IBC CODE COMMITTEES
