(A separately-hosted City of Rigby PDF titled 'Solar Permit' exists but its body text is actually a Fence Permit template and should not be used.)

The State of Idaho DOPL. Rigby and Jefferson County do not locally administer electrical permitting, so the electrical-connection scope of a solar array is a separate State of Idaho DOPL permit, distinct from this county-processed structural/building permit.
