Indiana has not adopted a mandatory green building code, but Indianapolis encourages high-performance design through the Thrive Indianapolis plan, expedited LEED permitting, and voluntary energy and stormwater incentives.
Indiana's state-adopted commercial energy code is based on ASHRAE 90.1 (older edition than national leaders) and the residential energy code follows an amended IECC, both enforced through Indianapolis DBNS as part of the building permit. There is no mandatory IgCC or LEED requirement, but the Thrive Indianapolis sustainability plan (2019) commits the city to lower-carbon municipal buildings and offers stormwater fee credits, expedited permitting, and density bonuses for LEED, Green Globes, or Enterprise Green Communities certification. The Office of Sustainability publishes a benchmark dashboard. Builders chasing certification should use Marion County stormwater credit manuals and Citizens Energy rebates for high-efficiency HVAC, insulation, and EV-ready wiring.
Few direct enforcement penalties because the rules are voluntary; failing to deliver promised certification can void permit incentives, density bonuses, or stormwater credits.
