Steps
Confirm the local jurisdiction has actually adopted IBC Appendix H, since it is an optional appendix rather than automatically part of the base code everywhere.
Prepare construction documents showing dimensions, materials, loads, stresses, and anchor/footing details as Appendix H requires.
Design the sign to withstand wind pressure per the wind-load provisions referenced by the local IBC adoption.
Check the jurisdiction's specific height or size exemption thresholds for pole signs, since these vary locally and Appendix H itself allows local amendment.
Size chain, cable, guy, or steel rod supports so working strength does not exceed one-fifth of ultimate strength, per Appendix H's allowable stress provisions.
Known gotchas
Appendix H is optional in the base IBC; confirm through the jurisdiction's code adoption ordinance that it is actually in force locally rather than assuming universal applicability.
Pole sign exemption height thresholds are set by local amendment and vary by city; don't reuse a threshold from one jurisdiction in another.
