This guide presents a plain-language overview of design and construction provisions important to the earthquake performance of one- and two-family detached dwellings and townhouses (referred to as dwellings and townhouses in this guide) constructed under the International Residential Code (IRC) (ICC, 2024a). The primary intended audiences for this guide are homebuilders, tradespeople working in the home building industry, and building department plan checkers and inspectors. Secondary audiences include architects, engineers, and homeowners with construction knowledge.
The objective of this MAT report is to provide actionable recommendations to improve residential building performance under wildfire conflagration conditions. It describes the MAT’s observations during the field deployments, draws conclusions based on those observations, and provides recommendations for actions that property owners can take to help increase the resiliency of their homes and neighborhoods to future wildfires. It also provides recommendations that local government officials, planners, builders, design professionals, and homeowners' associations can implement to reduce the potential impacts of wildfires on communities and improve their resilience.
This guide replaces the Home Builder's Guide to Seismic Resistant Construction and all earlier versions of FEMA 232. It presents seismic design and construction guidance for one- and two-family light frame residential structures that can be utilized by homebuilders, homeowners, and other non-engineers, and provides supplemental information to the 2003 edition of the International Residential Code. Includes background information on the principles of seismic resistance and how earthquake forces impact conventional residential construction and more detailed information on architectural considerations. Discussions of masonry and stone elements, examples of typical floor plans for earthquake resistant one- and two-story homes, excerpts of seismic requirements from building codes, and checklists for home builders are included. The guide also presents a series of "above code recommendations" and low cost measures that would increase the performance of the building and help keep it functional after an earthquake.
