Steps
Check whether the local adopting ordinance specifically references Appendix H, since IBC appendices are not mandatory unless the adopting jurisdiction says so
If adopted, review Appendix H's provisions on sign structure design, wood anchors/supports, and projecting/wall/roof sign requirements
Cross-check for local amendments — jurisdictions commonly delete or modify specific Appendix H sections (some remove portable-sign provisions entirely)
Confirm which IBC edition's Appendix H is locally in force (2015/2018/2021/2024 content and section numbers differ) before citing a specific section number
Coordinate Appendix H structural requirements with ASCE 7 wind load calculations and any local sign code for a complete permit submission
Known gotchas
Appendix H is optional by default under the base IBC — never assume it applies without confirming the local adoption ordinance references it
Local jurisdictions commonly amend or strike specific Appendix H sections, so a generic national copy of Appendix H may not reflect the actual locally enforced text
Section numbering and content differ across IBC editions, so citing a section number requires first confirming which edition is in force locally
