2025 Building Code Adoption Tracking: FEMA Region 4

This fact sheet summarizes the status of hazard-resistant building code adoption across states and territories in FEMA Region 4 as of 2025. It provides annual metrics on the percentage of communities adopting the latest International Building Code (IBC) and International Residential Code (IRC) editions, with details on code amendments and adoption rates by state. The document highlights how code adoption relates to resilience against flood, wind, hurricane, tornado, and seismic hazards, and identifies gaps in code coverage and enforcement. It is intended to inform state, local, tribal, and territorial officials, as well as FEMA and partner agencies, about regional progress and challenges in building code implementation.
