Answer: Yes. HUD is using the DOE provided map to determine state energy codes that are equivalent:

If the home meets the current energy code in the states marked as equivalent to IECC 2021 on the map then HUD staff have indicated they are compliant with their energy requirements. In states with local rule (those shown as white on the map) it may depend on the local jurisdiction having adopted the IECC 2021.
