6、o-date code addressing repair,alteration, addition or change of occupancy in existing buildings. The International Existing BuildingCode, in this 2015 edition, is designed to meet this need through model code regulations that safe-guard the public health and safety in all communities, large and smal
7、l.This comprehensive existing building code establishes minimum regulations for existing buildingsusing prescriptive and performance-related provisions. It is founded on broad-based principlesintended to encourage the use and reuse of existing buildings while requiring reasonable upgradesand improve
8、ments. This 2015 edition is fully compatible with all of the International Codes(I-Codes) published by the International Code Council (ICC), including the International BuildingCode, International Energy Conservation Code, International Fire Code, International Fuel GasCode, International Green Cons
9、truction Code, International Mechanical Code, ICC PerformanceCode, International Plumbing Code, International Private Sewage Disposal Code, InternationalProperty Maintenance Code, International Residential Code, International Swimming Pool andSpa Code, International Wildland-Urban Interface Codeand
10、International Zoning Code.The International Existing Building Code provisions provide many benefits, including the modelcode development process, which offers an international forum for building professionals to discussperformance and prescriptive code requirements. This forum provides an excellent
11、arena to debateproposed revisions. This model code also encourages international consistency in the application ofprovisions.DevelopmentThe first edition of the International Existing Building Code (2003) was the culmination of an effortinitiated in 2000 by a development committee appointed by the I
12、CC and consisting of representa-tives of the three statutory members of the International Code Council at that time, including: Build-ing Officials and Code Administrators International, Inc. (BOCA), International Conference ofBuilding Officials (ICBO) and Southern Building Code Congress Internation
13、al (SBCCI). The intent wasto draft a comprehensive set of regulations for existing buildings consistent with and inclusive of thescope of the existing model codes. Technical content of the latest model codes promulgated byBOCA, ICBO and SBCCI as well as other rehabilitation codes was utilized as the
14、 basis for the develop-ment, followed by a public forum in 2001 and the publication of the 2001 Final Draft. This 2015 edi-tion presents the code as originally issued in 2003 with the changes reflected in the 2006 edition,2009 edition, 2012 edition and with further changes approved through the ICC c
15、ode developmentprocess through 2013. 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 buildingsthat adequately protect public health, safety and welfare; provisions that do not unnecessarilyincrease constru
16、ction costs; provisions that do not restrict the use of new materials, products ormethods of construction; and provisions that do not give preferential treatment to particular typesor classes of materials, products or methods of construction.AdoptionThe International Code Council maintains a copyrig
17、ht in all of its codes and standards. Maintainingcopyright allows the ICC to fund its mission through sales of books, in both print and electronic for-mats. The International Existing Building Code is designed for adoption and use by jurisdictions thatrecognize and acknowledge the ICCs copyright in
18、the code, and further acknowledge the substan-tial shared value of the public/private partnership for code development between jurisdictions andthe ICC.The ICC also recognizes the need for jurisdictions to make laws available to the public. All ICC codesand ICC standards, along with the laws of many
19、 jurisdictions, are available for free in a nondownload-able form on the ICCs website. Jurisdictions should contact the ICC at adoptionsiccsafe.org to learniv 2015 INTERNATIONAL EXISTING BUILDING CODEhow to adopt and distribute laws based on the International Existing Building Code in a manner thatp
20、rovides necessary access, while maintaining the ICCs copyright.MaintenanceThe International Existing Building Code is kept up to date through the review of proposed changessubmitted by code enforcing officials, industry representatives, design professionals and otherinterested parties. Proposed chan
21、ges are carefully considered through an open code developmentprocess in which all interested and affected parties may participate.The contents of this work are subject to change through both the code development cycles andthe governmental body that enacts the code into law. For more information rega
22、rding the codedevelopment process, contact the Codes and Standards Development Department of the Interna-tional Code Council.While the development procedure of the International Existing Building Code ensures the high-est degree of care, the ICC, its members and those participating in the developmen
23、t of this code donot accept any liability resulting from compliance or noncompliance with the provisions becausethe ICC does not have the power or authority to police or enforce compliance with the contents ofthis code. Only the governmental body that enacts the code into law has such authority.Code
24、 Development Committee Responsibilities(Letter Designations in Front of Section Numbers)In each code development cycle, proposed changes to this code are considered at the CommitteeAction Hearings by the International Existing Building Code Development Committee. Proposedchanges to a code section ha
25、ving a number beginning with a letter in brackets are considered by adifferent code development committee. For example, proposed changes to code sections that arepreceded by the designation F (e.g., F 1404.2) are considered by the International Fire CodeDevelopment Committee at the Committee Action
26、Hearings.The content of sections in this code that begin with a letter designation is maintained by anothercode development committee in accordance with the following:A = Administrative Code Development Committee;BE = IBC Means of Egress Code Development Committee;BG = IBC General Code Development C
27、ommittee;BS = IBC Structural Code Development Committee;EC = International Energy Conservation Code Development Committee;F = International Fire Code Development Committee;FG = International Fuel Gas Code Development Committee;M = International Mechanical Code Development Committee; andP = Internati
28、onal Plumbing Code Development Committee.For the development of the 2018 edition of the I-Codes, there will be three groups of code devel-opment committees and they will meet in separate years. Note that these are tentative groupings.2015 INTERNATIONAL EXISTING BUILDING CODEvNote: Proposed changes t
29、o the ICC Performance Code will be heard by the code development committee noted in brackets in the text of the code.Code change proposals submitted for code sections that have a letter designation in front ofthem will be heard by the respective committee responsible for such code sections. Because
30、differ-ent committees hold code development hearings in different years, it is possible that some propos-als for this code will be heard by a committee in a different year than the year in which the primarycommittee for this code meets.For instance, Section 606.2.3 is designated as the responsibilit
31、y of the International BuildingCode Development Committee (Structural), along with all structural related provisions of the IEBC.This committee will conduct its code development hearings in 2015 to consider all code change pro-posals to the International Building Code and any portions of other codes
32、 that it is responsible for,including Section 606.2.3 of the IEBC and other structural provisions of the IEBC (designated withBS in front of those sections). Therefore, any proposals received for Section 606.2.3 will be consid-ered in 2015 by the IBC - Structural Code Development Committee.Another e
33、xample is that every section of Chapter 1 of this code is designated as the responsibilityof the Administrative Code Development Committee. That committee is part of the Group B codehearings. This committee will conduct its code development hearings in 2016 to consider all codechange proposals for C
34、hapter 1 of this code and proposals for Chapter 1 of all I-Codes except theIECC, IRC and ICC Performance Code. Therefore, any proposals received for Chapter 1 of this codewill be deferred for consideration in 2015 by the Administrative Code Development Committee.It is very important that anyone subm
35、itting code change proposals understand which code devel-opment committee is responsible for the section of the code that is the subject of the code changeproposal.

45、oaches to repair, alteration and additions to existing buildings.A large number of existing buildings and structures do not comply with the current building coderequirements for new construction. Although many of these buildings are potentially salvageable,rehabilitation is often cost-prohibitive be
46、cause compliance with all the requirements for new con-struction could require extensive changes that go well beyond the value of the building or the origi-nal scope of the alteration. At the same time, it is necessary to regulate construction in existingbuildings that undergo additions, alterations
47、, extensive repairs or change of occupancy. Such activ-ity represents an opportunity to ensure that new construction complies with the current buildingcodes and that existing conditions are maintained, at a minimum, to their current level of compli-ance or are improved as required to meet basic safe
48、ty levels. To accomplish this objective, and tomake the alteration process easier, this code allows for options for controlled departure from fullcompliance with the International Codes dealing with new construction, while maintaining basic lev-els for fire prevention, structural and life safety fea
49、tures of the rehabilitated building. This code provides three main options for a designer in dealing with alterations of existing build-ings. These are laid out in Section 301 of this code: OPTION 1: Work for alteration, repair, change of occupancy, addition or relocation of all existingbuildings shall be done in accordance with the Prescriptive Compliance Method given in Chapter 4.It should be noted that this method originates from the for
