A bill for an act relating to the national electrical code, and including effective date provisions.

SF 2433 updates Iowa's electrical code framework by adopting the International Energy Conservation Code (IECC), 2009 edition, as the "national energy code." It requires the electrical board to analyze cost impacts on new homes before adopting energy code changes, and mandates sellers of single-family homes built after January 1, 2027, to disclose in writing if the home doesn't meet the 2024 IECC standards. This bill directly affects homebuilders, electrical code administrators, and home sellers/buyers. The key mechanisms are the pre-adoption cost analysis and the new disclosure requirement for home sales. The bill takes effect January 1, 2027.
