Research notes
Opt-out (not opt-in). A unit may retain discretionary review only by adopting an opt-out ordinance by Dec 31 each year; scope is per topic (a city can opt out of duplex while leaving ADU by-right). Mandatory IHCDA barrier reporting. IC 32-31-1-20 (rent control / mandatory IZ preemption) is unaffected.
