Code Adoption and Change Process

Code Change Process

Regulatory: Proposed changes initially proceed through code committee meetings, and if approved, notice of intent is published in the Indiana Register. Proposed rules are published 60 days after notice, and two public hearings are held. The first is held 75 days after publication of the rules, and the second hearing is held 45 days after the first hearing. The Attorney General then has 45 days to review the rules before they proceed to the Governor. If the Governor signs off on the rules, they are effective not less than 30 days after being filed with the Secretary of State.
