Codes, Standards, and Permitting (Maui Wildfires Summary Report #1)

This summary report focuses on the performance of one- and two-family residential buildings impacted by the August 2023 wildfires on Maui. The performance of residential buildings varied depending on their design, construction type and quality, geographic location, siting, development density, landscape vegetation, distance to other surrounding flammable materials, and maintenance history. Several homes sustained damage from wind as well as fire, including wind damage to roof coverings, windows, and doors.

Reducing Wildfire Risk to Your Home (Maui Wildfires Recovery Advisory #2)

Defensible space is an area with limited combustibles surrounding your home that helps to reduce the chance that your home will catch fire during a wildfire event. Defensible space is up to 100 feet from your home and slows or stops the progression of wildfire. Defensible space, coupled with structural hardening, is critical to increasing your home’s likelihood of surviving a wildfire.

Marshall Fire Mitigation Assessment Team: Wildfire-Resilient Detailing, Joint Systems, and Interfaces of Residential Building Components

This document provides information on ways to reduce the vulnerability of residential structures to wildfire ignition due to windborne embers, hot gases, and flames penetrating common detailing joints and building component interfaces that exist throughout the exterior envelope of a building. This document provides information on measures that builders, contractors, and other design professionals can take to “seal” gaps at joints and retrofit building components and interfaces on the exterior surfaces. While the primary focus of this document is to provide guidance on retrofitting existing residential homes, many of the recommendations for increasing wildfire resiliency of common details, joint systems, and building component interfaces would also be applicable to new construction and commercial buildings

Mitigation Assessment Team Report: Marshall Fire Building Performance, Observations, Recommendations, and Technical Guidance (FEMA P-2320)

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.
