Amends existing law to provide for preemption, retroactive application, and future application.

This legislation amends the retroactivity clause of the Idaho Energy Conservation Code provisions contained in Idaho code 39-9701 to make it retroactive to the date of implementation. H660, passed into law in the 2022 legislative session put the 2018 Energy Conservation Code into statute and prohibits local jurisdictions from adopting energy conservation codes or requirements that differ from or are more extensive than those provided for in 39-9701. The retroactivity language contained in that chapter has resulted in misinterpretation or abuse of the legislative intent of H660 by some jurisdictions. This legislation intends to clarify that provisions of 39-9701 are in effect.
