the purpose of Significant Changes to the International Building Code® 2018 Edition is to familiarize building officials, fire officials, plans examiners, inspectors, design professionals, contractors, and

others in the construction industry with many of the important changes in the 2018 International Building Code® (IBC®). this publication is de-signed to assist those code users in identifying the specific code changes that have occurred and, more important, understanding the reasons be-hind the changes. It is also a valuable resource for jurisdictions in their code-adoption process.

only a portion of the total number of code changes to the IBC are dis-cussed in this book. the changes selected were identified for a number of reasons, including their frequency of application, special significance, or change in application. However, the importance of those changes not included is not to be diminished. Further information on all code changes can be found in the Complete revision History to the 2018 I-Codes, available from the International Code Council® (ICC®) online store at http://shop.iccsafe .org. the revision history provides the published documentation for each successful code change contained in the 2018 IBC since the 2015 edition.

the IBC discussion in this book is organized into eight general catego-ries, each representing a distinct grouping of code topics. It is arranged to follow the general layout of the IBC, including code sections and section number format. the table of contents, in addition to providing guidance in use of this publication, allows for quick identification of those signifi-cant code changes that occur in the 2018 IBC.

this edition of Significant Changes to the International Building Code includes a ninth Part that addresses a limited number of selected code changes that occurred in the 2018 edition of the International Existing Building Code (IeBC). applicable to all existing buildings, the IeBC is in-tended to provide flexibility to permit the use of alternative approaches to achieve compliance with minimum requirements to safeguard the public health, safety, and welfare. Both structural and nonstructural changes are addressed in this publication.

throughout the book, each change is accompanied by a photograph, an application example, or an illustration to assist and enhance the reader’s

understanding of the specific change. a summary and a discussion of the significance of the changes are also provided. each code change is identi-fied by type, be it an addition, modification, clarification, or deletion.

the code change itself is presented in a format similar to the style utilized for code-change proposals. deleted code language is shown with a strike-through, whereas new code text is indicated by underlining. as a result, the actual 2018 code language is provided, as well as a comparison with the 2015 language, so the user can easily determine changes to the specific code text.

as with any code-change text, Significant Changes to the International Building Code 2018 Edition is best used as a study compan-ion to the 2018 IBC. Because only a limited discussion of each change is provided, the code itself should always be referenced in order to gain a more comprehensive understanding of the code change and its application.

the commentary and opinions set forth in this text are those of the authors and do not necessarily represent the official position of the ICC. In addition, they may not represent the views of any enforcing agency, as such agencies have the sole authority to render interpretations of the IBC. In many cases, the explanatory material is derived from the reasoning ex-pressed by the code-change proponent.

Comments concerning this publication are encouraged and may be directed to the ICC at [email protected].

About the International Building Code®

Building officials, design professionals, and others involved in the build-ing construction industry recognize the need for a modern, up-to-date building code addressing the design and installation of building systems through requirements emphasizing performance. the International Building Code (IBC), in the 2018 edition, is intended to meet these needs through model code regulations that safeguard the public health and safety in all communities, large and small. the IBC is kept up to date through the open code-development process of the International Code Council (ICC). the provisions of the 2015 edition, along with those code changes approved through 2016, make up the 2018 edition.

the ICC, publisher of the IBC, was established in 1994 as a nonprofit organization dedicated to developing, maintaining, and supporting a single set of comprehensive and coordinated national model building construc-tion codes. Its mission is to provide the highest-quality codes, standards, products, and services for all concerned with the safety and performance of the built environment.

the IBC is 1 of 15 International Codes® published by the ICC. this comprehensive building code establishes minimum regulations for build-ing systems by means of prescriptive and performance-related provisions. It is founded on broad-based principles that make possible the use of new materials and new building designs. the IBC is available for adoption and use by jurisdictions internationally. Its use within a governmental jurisdiction is intended to be accomplished through adoption by refer-ence, in accordance with proceedings establishing the jurisdiction’s laws.
