Flood Resistant Provisions of the 2018 International Codes (2018)

The 2018 edition of the International Codes (I-Codes) contains provisions that meet or exceed the minimum flood-resistant design and construction requirements of the NFIP for buildings and structures. This page contains the following documents, prepared by FEMA, related to the flood provisions of the 2018 I-Codes:

- A compilation of flood resistant provisions of the 2018 I-Codes (IBC, IRC, IEBC, IMC, IPC, IFGC, IFC, ISPSC, IPSDC, and ICC Performance Code)

- A summary of changes to the flood provisions from the 2015 I-Codes

- A checklist that can be used to guide floodplain managers, building officials, and designers as they compare the flood provisions of the 2018 I-Codes and ASCE 24-14 to the minimum requirements of the NFIP. It is based on the standard checklist used by FEMA and States to review local floodplain management regulations/ordinances to determine whether such regulations and ordinances are complete for the purpose of participating in the NFIP

- Highlights of ASCE 24-14, Flood Resistant Design and Construction, a referenced standard in the 2018 IBC and IRC

Highlights of ASCE 24-14 Flood Resistant Design and Construction

The American Society of Civil Engineers (ASCE) 24-14 is a referenced standard in the 2015 International Building Code® (IBC) and the 2015 International Residential Code® (IRC). Building and structures within the scope of the IBC proposed to be constructed in flood hazard areas must be designed in accordance with ASCE 24-14. The IRC requires dwellings in floodways to be designed in accordance with ASCE 24-14 and includes an alternative that allows communities to require homes in any flood zone to be designed in accordance with ASCE 24-15. Highlights of ASCE 24-14 that complement the NFIP minimum requirements include Building Performance; Flood-Damage Resistant Materials; Utilities and Service Equipment and Siting Considerations.
