Overview of FEMA P-804 (2023), Wind Retrofit Guide for Residential Buildings in Hurricane-Prone Regions

This overview summarizes FEMA P-804 (2023), which provides updated technical guidance for selecting and implementing cost-effective wind retrofit projects for existing one- and two-family dwellings in hurricane-prone regions of the United States and its territories. The guide introduces a tiered system of Mitigation Packages—Basic, Intermediate, and Advanced—each comprising specific retrofit measures to strengthen the building envelope and load path against high winds and windborne debris. It references current codes and standards, aligns with the 2020 IBHS FORTIFIED Home Hurricane designations, and is intended for homeowners, contractors, evaluators, and design professionals. The document also incorporates lessons learned from recent hurricanes and FEMA Mitigation Assessment Team deployments.
