NFPA 225 Model Manufactured Home Installation Standard 2017 Edition This edition of NFPA 225, Model Manufactured Home Installation Standard, was prepared by the Technical Committee on M

12、anufactured Housing. It was issued by the Standards Council on November 11, 2016, with an effective date of December 1, 2016, and supersedes all previous editions. This edition of NFPA 225 was approved as an American National Standard on December 1, 2016. Origin and Development of NFPA 225 The rst e

13、dition of NFPA 225 was developed as a result of numerous actions that led to NFPA being further involved in manufactured housing regulatory issues. First, it should be noted that the previous responsibility for management of the ANSI standard for this subject was with the National Conference of Stat

14、es on Building Codes and Standards (NCSBCS). Their 1994 document, NCSBCS A 225.1, Manufactured Home Installations, formed the basis for the rst edition of NFPA 225. In 2000, an agreement in principle was reached between NCSBCS and NFPA that would allow transfer of the ANSI standard to NFPA. It was a

15、 logical move, since an installation standard would use the basic criteria of the manufactured housing standard, as contained in NFPA 501, Standard on Manufactured Housing, for a completed unit to be efciently, effectively, safely, and adequately installed. The second area that highlighted the need

16、for the installation standard was passage of the Manufactured Housing Improvement Act (MHIA) of 2000. Although the MHIA was not implemented until 2001, the act established a broad set of criteria to ensure that changes could be effectively promulgated with respect to the design, construction, and in

17、stallation of the stock of manufactured homes. A key provision of the MHIA was the need to establish an installation standard that could be utilized by the U.S. Department of Housing and Urban Development (HUD), the ultimate overseer of manufactured homes. Thus, not only was NFPA 225 developed to pi

18、ck up where that previous NCSBCS document had left off, it became an integral part of providing another option, along with other state-sponsored installation standards, that could potentially be considered by HUD. The installation criteria in this standard are widely varied and cover a range of subj

19、ects. As written, NFPA 225 is intended to be applied to new installations, regardless of whether they are at new or existing manufactured housing sites. These criteria are intended to be adopted and enforced by the authority having jurisdiction when an alternative state or federal installation stand

20、ard does not exist. In addition to covering the basic administrative features and criteria, provisions are included for site preparation work, foundations, and procedures during on-site installation or erection, as well as management of appliances and utility connections. Requirements reecting curre

21、nt design loads and practices associated with seismic, wind, and ood events have been included. These provisions govern single-section as well as multisection homes and provide requirements for everything from interconnection criteria for multisection homes to anchor provisions to restrict movement

22、from wind loads, seismic events, and oods. The 2009 edition added extensive revisions to the ground anchor design and spacing criteria. These revisions included the addition of more detail concerning soil conditions, width of the unit being installed, and anticipated loading on the home. An entirely

23、 new chapter, Chapter 15, outlined a design approach for prescriptive ood design provisions. These changes allowed the 2009 edition of NFPA 225 to align more closely with the requirements of FEMAs ood-resistant design criteria and the 2005 edition of ASCE/SEI 7, Minimum Design Loads for Buildings an

24、d Other Structures. The 2013 edition included a new section on retroactivity in Chapter 1, and a new provision requiring carbon monoxide detectors was added to align with the requirements for other residential occupancies. Also, the lists of publications in Chapter 2 and Annex E were updated.MODEL M

25、ANUFACTURED HOME INSTALLATION STANDARD 225-2 2017 Edition The 2017 edition includes the following changes: (1) The 2013 standard provided guidance on smoke alarms and carbon monoxide detectors but was silent on how re sprinkler systems should be dealt with during the installation process. For the 20

26、17 edition, language has been added to ensure that the installer is provided with the necessary information from the manufacturer to accomplish the connection of the re sprinkler system and system inspection so the system performs as the codes and standards intend. (2) In Section 11.2, the committee

27、 has removed the word approved as being beyond the scope of this document. (3) Because ASCE 24, Flood Resistant Design and Construction, was revised and republished in 2014, 12.4.2.2.1 claries which item refers to non-engineered ood openings, revises the referenced section number to match the 2014 e

28、dition of ASCE 24 and also claries which item refers to engineered ood openings. (4) Referenced publications have been updated as appropriate.COMMITTEE PERSONNEL 225-3 2017 Edition Technical Committee on Manufactured Housing John Lake, Chair City of Gainesville, FL E Fred Benn, Advanced Automatic Sp
