Nationwide Building Code Adoption Tracking

FEMA tracks current building code adoption status for state, local, tribal and territorial governments (SLTTs), reaching approximately 22,000 jurisdictions across the nation. This effort, often referred to as BCAT (Building Code Adoption Tracking), evaluates several aspects of a community’s natural hazard risks and building code adoption, including:

  • State or territory requirements for mandatory building code adoption
  • Building code adoption status for jurisdictions, including construction requirements for residential and commercial
  • Identification of known weakenings of flood, wind, and seismic provisions of adopted building codes

The Building Code Adoption Portal is an interactive WebGIS map that tracks five hazards (flood, seismic, tornado, hurricane wind, damaging wind) and displays:

  • Code adoption information for Census Incorporated Places
  • Additional metadata such as the latest decennial U.S. Census population and National Flood Insurance Program Community Identification (CID) number
  • Mutual aid layer displaying mutual aid laws
  • Regulations information from the annual Mutual Aid for Building Departments fact sheets
  • High risk areas and code adoption and weakening information for each individual hazard, or view a comprehensive combined hazards layer
