Des Moines does not impose a mandatory green building code beyond Iowa's adopted IECC energy code, but the 2024 Climate Action Plan promotes voluntary high-performance standards, EV-ready wiring, and electrification incentives for new construction.
Iowa adopts the International Energy Conservation Code (IECC) statewide under Iowa Code Chapter 103A, setting minimum insulation, window, lighting, and HVAC efficiency requirements for new buildings in Des Moines. Beyond that floor, the city's 2024 Climate Action Plan encourages voluntary measures, including LEED, ENERGY STAR Multi-Family, and Passive House paths, EV charging readiness, solar-ready roofs, and heat-pump installations. Some city-funded affordable housing and capital projects must meet enhanced sustainability standards by policy. State law preempts local energy codes that exceed the state-adopted version, so private developers cannot be forced beyond the IECC, but they can earn incentives or expedited review for green features.
Failing to meet the state-adopted IECC during plan review or inspection delays certificate of occupancy, while voluntary green commitments tied to incentives may be clawed back if not delivered.
