, PREFACE
Introduction
The International Existing Building Code (IEBC) establishes minimum requirements for existing
buildings using prescriptive and performance-related provisions. It is founded on broad-based prin-
ciples intended to encourage the use and reuse of existing buildings while requiring reasonable
upgrades and improvements. This 2018 edition is fully compatible with all of the International
Codes (I-Codes) published by the International Code Council (ICC), including the International
Building Code, International Energy Conservation Code, International Fire Code, International
Fuel Gas Code, International Green Construction Code, International Mechanical Code, Interna-
tional Plumbing Code, International Private Sewage Disposal Code, International Property Mainte-
nance Code, International Residential Code, International Swimming Pool and Spa Code,
International Wildland-Urban Interface Code, International Zoning Code and International Code
Council Performance Code.
The I-Codes, including this International Existing Building Code, 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 U.S. and in other countries. However, the
impact of the codes extends well beyond the regulatory arena, as they are used in a variety of non-
regulatory 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, con-
struction and safety.
• Certification of building and construction-related products.
• U.S. 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 pro-
fessionals 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.
Development
This 2018 edition presents the code as originally issued, with changes reflected in the 2006 through
2015 editions and further changes approved by the ICC Code Development Process through 2017. A
new edition such as this is promulgated every 3 years.
This code is founded on principles intended to encourage the use and reuse of existing buildings
that adequately protect 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 particular types
or classes of materials, products or methods of construction.
