This fact sheet summarizes the status of hazard-resistant building code adoption across states and territories in FEMA Region 9 as of 2025. It presents annual metrics on the percentage of communities adopting the 2021 or later International Building Code (IBC) and International Residential Code (IRC) without weakening resilience provisions for high-risk hazards. The document details state and territory adoption levels, code strengths or weaknesses, and the population protected by up-to-date codes for flood, wind, hurricane, and seismic risks. It is intended to inform policy, funding, and resilience planning for building safety in the region.
