Internationally, code officials 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®, in this 2006 edition, is
designed to meet these needs through model code regulations that safeguard the public health and safety in all communities, large
This comprehensive building code establishes minimum regulations for building systems using prescriptive and perfor-
mance-related provisions. It is founded on broad-based principles that make possible the use of new materials and new building
designs. This 2006 edition is fully compatible with all the International Codes® (I-Codes®) published by the International Code
Council (ICC)®, including the ICC Electrical Code®, International Energy Conservation Code®, International Existing Building
Code®, International Fire Code®, International Fuel Gas Code®, International Mechanical Code®, ICC Performance Code®, Inter-
national Plumbing Code®, International Private Sewage Disposal Code®, International Property Maintenance Code®, Interna-
tional Residential Code®, International Wildland-Urban Interface CodeTM and International Zoning Code®.
The International Building Code provisions provide many benefits, among which is the model code development process that
offers an international forum for building professionals to discuss performance and prescriptive code requirements. This forum pro-
vides an excellent arena to debate proposed revisions. This model code also encourages international consistency in the application
The first edition of the International Building Code (2000) was the culmination of an effort initiated in 1997 by the ICC. This
included five drafting subcommittees appointed by ICC and consisting of representatives of the three statutory members of the
International Code Council at that time, including: Building Officials and Code Administrators International, Inc. (BOCA), Inter-
national Conference of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI). The intent was to
draft a comprehensive set of regulations for building systems consistent with and inclusive of the scope of the existing model codes.
Technical content of the latest model codes promulgated by BOCA, ICBO and SBCCI was utilized as the basis for the development,
followed by public hearings in 1997, 1998 and 1999 to consider proposed changes. This 2006 edition presents the code as originally
issued, with changes reflected in the 2003 edition and further changes approved through the ICC Code Development Process
through 2005. A new edition such as this is promulgated every three years.
This code is founded on principles intended to establish provisions consistent with the scope of a building code that adequately
protects public health, safety and welfare; provisions that do not unnecessarily increase construction costs; provisions that do not
restrict the use of new materials, products or methods of construction; and provisions that do not give preferential treatment to par-
ticular types or classes of materials, products or methods of construction.
The International Building Code is available for adoption and use by jurisdictions internationally. Its use within a governmental
jurisdiction is intended to be accomplished through adoption by reference in accordance with proceedings establishing the jurisdic-
tion's laws. At the time of adoption, jurisdictions should insert the appropriate information in provisions requiring specific local
information, such as the name of the adopting jurisdiction. These locations are shown in bracketed words in small capital letters in
the code and in the sample ordinance. The sample adoption ordinance on page v addresses several key elements of a code adoption
ordinance, including the information required for insertion into the code text.
The International Building Code is kept up to date through the review of proposed changes submitted by code enforcing 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 contents of this work are subject to change both through the Code Development Cycles and the governmental body that
enacts the code into law. For more information regarding the code development process, contact the Code and Standard Develop-
ment Department of the International Code Council.
While the development procedure of the International Building Code assures the highest degree of care, ICC, its members and
those participating in the development of this code do not accept any liability resulting from compliance or noncompliance with the
provisions because ICC does not have the power or authority to police or enforce compliance with the contents of this code. Only the
governmental body that enacts the code into law has such authority.

Letter Designations in Front of Section Numbers
In each code development cycle, proposed changes to the code are considered at the Code Development Hearings by the ICC Fire
Code Development Committee, whose action constitutes a recommendation to the voting membership for final action on the pro-
posed change. Proposed changes to a code section that has a number beginning with a letter in brackets are considered by a different
code development committee. For example, proposed changes to code sections that have [F] in front of them (e.g. [F] 903.1.1.1) are
considered by the ICC Fire Code Development Committee at the code development hearings.
The content of sections in this code that begin with a letter designation are maintained by another code development committee in
accordance with the following:
[E] = International Energy Conservation Code Development Committee;
[EB] = International Existing Building Code Development Committee;
[EL] = ICC Electrical Code Development Committee;
[F] = International Fire Code Development Committee;
[FG] = International Fuel Gas Code Development Committee;
[M] = International Mechanical Code Development Committee; and
[P] = International Plumbing Code Development Committee.
Solid vertical lines in the margins within the body of the code indicate a technical change from the requirements of the 2003 edition.
Deletion indicators in the form of an arrow ( ) are provided in the margin where an entire section, paragraph, exception or table
has been deleted or an item in a list of items or a table has been deleted.

The International Codes are designed and promulgated to be adopted by reference by ordinance. Jurisdictions wishing to adopt the
2006 International Building Code as an enforceable regulation governing structures and premises should ensure that certain factual
information is included in the adopting ordinance at the time adoption is being considered by the appropriate governmental body.
The following sample adoption ordinance addresses several key elements of a code adoption ordinance, including the information
required for insertion into the code text.
