2018 International Building Code
The 2018 International Building Code Document (PDF) contains Appendix G - Flood-resistant Construction. You can search the 2018 IBC for more information on flood construction requirements by searching for the word FLOOD. Below are some examples of where flood-resistant construction code sections can be found.
Appendix G - Flood-resistant Construction:
Is intended to fulfill the flood-plain management and administrative requirements of the National Flood Insurance Program (NFIP) that are not included in the code. Communities that adopt the IBC and Appendix G will meet the minimum requirements of NFIP as set forth in Title 44 of the Code of Federal Regulations.
Flood Hazard Areas Section 202 and 1612.3
Section 16.12 Flood Loads:
Within flood hazard areas as established in Section 1612.3, all new construction of buildings, structures and portions of buildings and structures, including substantial improvement and restoration of substantial damage to buildings and structures, shall be designed and constructed to resist the effects of flood hazards and flood loads. For buildings that are locate in more than one flood hazard area, the provisions associated with the most restrictive flood hazard area shall apply.
