ICC Multi-Hazard Resiliency for Residential Construction Committee (IS-MHRRC)
As an ANSI accredited standards developing organization, ICC is collaborating with the Insurance Institute for Business & Home Safety (IBHS) in the development of a portfolio of individual hazard mitigation standards.
Resiliency is an important factor relative to a building’s response to extreme events; hence, the fundamental goal of this committee is the development of a portfolio of Consensus Standards relevant to a wide range of hazards affecting modern residential construction three stories and less. Hazards to be considered include, but not limited to, high winds (hurricanes/typhoons, tornados, and thunderstorms), seismic, tsunami, and wildfires.
The first task of this committee updated ICC 600, entitled, “Standard for Residential Construction in High-Wind Regions.” to create the 2020 edition. The committee has primary responsibility for updating the prescriptive methodologies of resistant design and construction details for building and other structures of wood framed, steel framed, concrete, or masonry construction directed toward ensuring structural integrity. This includes prescriptive details for walls, floors, roofs, foundations, windows, doors, and other applicable components of construction in order to be consistent with industry practices.
The next order of committee business will be the development of new ICC 605, Standard for Residential Construction in Regions with Wildfire Hazard. The fundamental goal is to develop a Standard relevant to a wildfire hazard affecting modern residential construction three stories and less increasing the likelihood that the structure can continue to be useable and reduce rebuilding time. The ICC Board of Directors appointed additional committee members at their March 2022 meeting in preparation for the development cycle to begin.
ICC IS-MHRRC Multi-Hazard Resiliency for Residential Construction
The Multi-Hazard Resiliency for Residential Construction (IS-MHRRC) committee was first appointed by the ICC Board of Directors in July 2019 and has primary responsibility for the development as American National Standards. All standards development is subject to ICC's Consensus Procedures.
Applications to serve on the committee were received on June 12, 2019 for the ICC Board of Directors consideration in response to a call for committee in Apr 2019. Read more.
The ICC adheres to openness and transparency in our Standards development process. All ICC Standards committee meetings are open to the public. Any interested party can participate in committee meetings and can be considered by the committee for membership on any work-group that the committee creates. Interested parties will be notified by email of standards activities related to IS-MHRRC, including committee meetings, sub-group meetings and the availability of standard development documentation. If you wish to be placed on the “interested parties” list for the development of these standards, please email the IS-MHRRC Secretariat Keith Enstrom, P.E. at email@example.com.
The most recent in-person meeting of the IS-MHRRC committee was held Dec. 2 - 4, 2019 at the IBHS facility in Richburg, SC. The meeting was well attended. Meeting minutes subject to committee approval are posted under Committee Documents. Read more….
ICC 600 -2020 has been ANSI Approved as of December 1, 2020. The document is available in the ICC Store.
The first in-person public meeting of the committee to develop new ICC 605 has been scheduled for October 6 and 7, 2022 at 10:00 am ET at the IBHS facility in Richburg, SC. The meeting is open to the public and interested parties may participate in task groups created by the committee. The Meeting Notice is posted below with more details on the schedule, agenda and how to participate. Also please see the "IBHS Research Center Logistics" and "Covid Protocol" posted below for more information on visiting the facility and where to stay.
The ICC 605 standard will specify enhanced prescriptive methodologies of wildfire resistant design and construction details for new and existing buildings and other structures of wood framed, steel framed, concrete, or masonry construction sited in wildfire hazard areas. The standard will provide prescriptive details for walls, floors, roofs, foundations, windows, doors, and other applicable components of construction. The Standard will provide a methodology for the identification, assessment, and retrofit of existing residential dwellings to protect homes in wildfire hazard areas.
