Michigan adopts the 2015 IECC (International Energy Conservation Code) under Part 10 of MCL 125.1502. New construction in Wayne County must meet insulation, glazing, and HVAC efficiency thresholds; Detroit pursues additional sustainability goals.
Michigan's Uniform Energy Code applies statewide, requiring R-49 attic insulation, R-20 wall insulation, U-0.32 windows, and Energy Star appliances in new homes. Commercial buildings must comply with ASHRAE 90.1-2013. Wayne County's joint Detroit Public Health Department supports voluntary sustainability programs but does not impose stricter mandates. Detroit's Green Building Ordinance (2010) requires LEED Silver certification for city-funded projects over $5 million. Single-family home renovations exceeding 50% replacement value trigger full code compliance. Solar-ready electrical conduit is required in new homes by Michigan Building Code amendments effective 2025. DTE Energy offers rebates for above-code performance.
Failing IECC compliance prevents certificate of occupancy issuance. Civil fines reach $10,000 per violation. Falsified energy compliance documents constitute misdemeanor fraud under building code enforcement.
