PRINTED IN THE U.S.A.2015 INTERNATIONAL WILDLAND-URBAN INTERFACE CODEiiiPREFACEIntroductionInternationally, code officials recognize the need for a modern, up-to-date code addressing the mit-igation of fire in the wildland-urban interface. The International Wildland-Urban Inter

6、face Code, inthis 2015 edition, is designed to bridge the gap between enforcement of the International BuildingCodeand the International Fire Codeby mitigating the hazard of wildfires through model coderegulations, which safeguard the public health and safety in all communities, large and small.This

7、 comprehensive wildland-urban interface code establishes minimum regulations for land useand the built environment in designated wildland-urban interface areas using prescriptive and per-formance-related provisions. It is founded on data collected from tests and fire incidents, technicalreports and

8、mitigation strategies from around the world. This 2015 edition is fully compatible withall of the International Codes(I-Codes) published by the International Code Council (ICC), includ-ing the International Building Code, International Energy Conservation Code, International Exist-ing Building Code,

9、 International Fire Code, International Fuel Gas Code, International GreenConstruction Code, International Mechanical Code, ICC Performance Code, International Plumb-ing Code, International Private Sewage Disposal Code, International Property Maintenance Code,International Residential Code, Internat

10、ional Swimming Pool and Spa Code, and InternationalZoning Code.The International Wildland-Urban Interface Code provisions provide many benefits, including themodel code development process, which offers an international forum for fire safety professionalsto discuss performance and prescriptive code

11、requirements. This forum provides an excellent arenato debate proposed revisions. This model code also encourages international consistency in theapplication of provisions.DevelopmentThe first edition of the International Wildland-Urban Interface Code (2003) was the culmination ofan effort initiated

12、 in 2001 by the ICC and the three statutory members of the International CodeCouncil: Building Officials and Code Administrators International, Inc. (BOCA), International Confer-ence of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI). Theintent was to draft a comp

13、rehensive set of regulations for mitigating the hazard to life and propertyfrom the intrusion of fire from wildland exposures and fire from adjacent structures, and preventingstructure fires from spreading to wildland fuels. Technical content of the 2000 Urban-WildlandInterface Code, published by th

14、e International Fire Code Institute, was utilized as the basis for thedevelopment, followed by the publication of the 2001 Final Draft. This 2015 edition presents thecode as originally issued, with changes approved through the ICC Code Development Processthrough 2013. A new edition such as this is p

15、romulgated every 3 years.This code is founded on principles intended to mitigate the hazard from fires through the devel-opment of provisions that adequately protect public health, safety and welfare; provisions that donot unnecessarily increase construction costs; provisions that do not restrict th

16、e use of new materi-als, products or methods of construction; and provisions that do not give preferential treatment toparticular types or classes of materials, products or methods of construction.AdoptionThe International Code Council maintains a copyright in all of its codes and standards. Maintai

17、ningcopyright allows ICC to fund its mission through sales of books, in both print and electronic formats.The International Wildland-Urban Interface Code is designed for adoption and use by jurisdictionsthat recognize and acknowledge the ICCs copyright in the code, and further acknowledge the sub-st

19、lic. All ICCcodes and ICC standards, along with the laws of many jurisdictions, are available for free in a non-downloadable form on the ICCs website. Jurisdictions should contact the ICC at adoptionsicc-safe.org to learn how to adopt and distribute laws based on the International Wildland-UrbanInte

20、rface Code in a manner that provides necessary access, while maintaining the ICCs copyright.MaintenanceThe International Wildland-Urban Interface Code is kept up to date through the review of proposedchanges submitted by code enforcing officials, industry representatives, design professionals andoth

21、er interested parties. Proposed changes are carefully considered through an open code develop-ment process 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 co

22、de into law. For more information regarding the codedevelopment process, contact the Codes and Standards Development Department of the Interna-tional Code Council.While the development procedure of the International Wildland-Urban Interface Code ensuresthe highest degree of care, the ICC, its member

23、s and those participating in the development of thiscode do not accept any liability resulting from compliance or noncompliance with the provisionsbecause the ICC does not have the power or authority to police or enforce compliance with the con-tents of this code. Only the governmental body that ena

24、cts the code into law has such authority.Code Development Committee Responsibilities(Letter Designations in Front of Section Numbers)In each code development cycle, proposed changes to the code are considered at the CommitteeAction Hearing by the International Fire Code Development Committee, whose

25、action constitutes arecommendation to the voting membership for final action on the proposed change. Proposedchanges to a code section that has a number beginning with a letter in brackets are considered by adifferent code development committee. For example, proposed changes to code sections or defi

26、ni-tions that have BG in front of them (e.g., Section 202 BG DWELLING), are considered by the IBC General Code Development Committee at the Committee Action Hearing.The content of sections in this code that begin with a letter designation is maintained by anothercode development committee in accorda

27、nce with the following:A = Administrative Code Development Committee;BF = IBC Fire Safety Code Development Committee;BG = IBC General Code Development Committee;F = International Fire Code Development Committee; andZ = International Zoning Code Development Committee.For the development of the 2018 e

28、dition 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.0b_pref_iwuic_15.fm Page iv Friday, May 2, 2014 12:16 PM2015 INTERNATIONAL WILDLAND-URBAN INTERFACE CODEvNote: Proposed changes to the ICC P

29、erformance 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 differ-ent

30、committees hold code development hearings in different years, it is possible that some propos-als for this code will be heard by committees in both the 2015 (Group A) and the 2016 (Group B)code development cycles.For instance, every section of Chapter 1 of this code is designated as the responsibili

31、ty of theAdministrative Code Development Committee, and that committee is part of the Group B portion ofthe hearings. This committee will hold its code development hearings in 2016 to consider all codechange proposals for Chapter 1 of this code and proposals for Chapter 1 of all I-Codes except theIn

32、ternational Energy Conservation Code, International Residential Code and ICC Performance Code.Therefore, any proposals received for Chapter 1 of this code will be assigned to the AdministrativeCode Development Committee for consideration in 2016.It is very important that anyone submitting code chang

33、e proposals understand which code devel-opment committee is responsible for the section of the code that is the subject of the code changeproposal.

43、ent into traditionally nonurban areas haveincreasingly brought humans into contact with wildfires. Between 1985 and 1994, wildfiresdestroyed more than 9,000 homes in the United States. Generally, these homes were located inareas “where structures and other human development meet or intermingle with

44、undevelopedwildland or vegetative fuels,” also known as the wildland-urban interface.The International Wildland-Urban Interface Code (IWUIC) is a model code that is intended to beadopted and used supplemental to the adopted building and fire codes of a jurisdiction. The unre-stricted use of property

45、 in wildland-urban interface areas is a potential threat to life and propertyfrom fire and resulting erosion. The IWUIC has as its objective the establishment of minimum spe-cial regulations for the safeguarding of life and property from the intrusion of fire from wildland fireexposures and fire exp

The IWUIC, like other codes published by ICC, is arranged

48、and organized to follow logicalsteps that generally occur during a plan review or inspection. The IWUIC is divided as follows:The following is a chapter-by-chapter synopsis of the scope and intent of the provisions of the Inter-national Wildland-Urban Interface Code:Chapter 1 Scope and Administratio

49、n. This chapter contains provisions for the application,enforcement and administration of subsequent requirements of the code. In addition to establish-ing the scope of the code, Chapter 1 identifies which buildings and structures come under its pur-view. Chapter 1 is largely concerned with maintaining “due process of law” in enforcing theregulations contained in the body of the code. Only through careful observation of the administra-tive provisions
