To participate in the National Flood Insurance Program (NFIP), communities must adopt and enforce regulations and codes that apply to new development in Special Flood Hazard Areas (SFHAs). Local floodplain management regulations and codes contain minimum NFIP requirements that apply not only to new structures, but also to existing structures which are “substantially improved (SI)” or “substantially damaged (SD).” This Desk Reference provides practical guidance and suggested procedures to implement the NFIP requirements for SI/SD.

For answers to frequently asked questions about SI/SD, see FEMA 213, Answers to Questions About Substantially Improved/Substantially Damaged Buildings (2018), at https://www.fema.gov/media-library/assets/documents/169099.”
