Building Science Resource Library
The Building Science Resource Library contains all of FEMA’s hazard-specific guidance that focuses on creating disaster-resistance communities.
You can search for a document by its title, or filter the collection to browse by:
- Disaster Type: High winds, flood, earthquake, etc.
- Document Type: Brochure, report, fact sheet, infographic, etc.
- Audience: Building professionals & engineers, individuals & homeowners, teachers & kids, etc.
Homeowners, business owners, design professionals and builders in wildfire-prone regions can benefit from understanding general fire resistance characteristics of common construction materials and building products. This Recovery Advisory aims to provide a list of materials that can withstand higher exposure and help slow the spread of fire, but it is important to remember that fire-resistant does not mean fire-proof.
As the recovery efforts continue on Maui, this is a current list of resources available at the one-year anniversary of the Maui wildfires. Homeowners, business owners, public officials, as well as design and construction professionals can benefit from using the following wildfire resources in recovery efforts.
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.
This Recovery Advisory, focused on one- and two-family dwellings, presents important fire safety recommendations for design professionals, including architects, engineers, installation professionals and contractors to reduce the likelihood of ignition and structure-to-structure fire spread in single family homes during a wildfire, where building setbacks and defensible space may be limited.
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.

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
This document provides homeowners with steps they can take now to decrease the likelihood their homes will ignite due to direct flame contact, ember intrusion, or hot gases from wildfires at various physical vulnerabilities throughout the exterior envelope of the house. Specifically, it provides information about some measures that homeowners can take to address vulnerabilities at joints, gaps, vents, and attachments such as decks and fences.
This document helps planners, developers, local land management personnel and private property owners identify how wildfires interact with other natural hazards and mitigate the impact of these multi-hazard events. The information in this document can be used to guide the incorporation of site-based wildfire mitigation strategies into planning, community siting and zoning requirements. This document can also guide the adoption of proactive planning, development and maintenance strategies that can minimize future risk of multi-hazard events.
This document provides recommendations to contractors and designers on new building construction that may prevent or slow the spread of a fire from structure-to-structure in densely-spaced neighborhoods.
