House File 2361 was signed in April 2006. This law rescinded Iowa's minimum energy efficiency standard for residential construction, the "home heating index," and instead requires the state building commissioner to adopt energy conservation requirements based on a nationally recognized building energy code. The State Building Code Commissioner, in conjunction with the State's Building Code Advisory Council, adopts rules and holds public hearings on the proposed rules.
On October 21, 2009 the Iowa Building Code Advisory Council, after previously issuing a notice of intended action (NIA), approved the adoption of several amendments to the State Building Code, including the adoption of the 2009 IECC effective January 1, 2010 (with a three month transition period during which the previous code, the 2006 IECC, may still be used). Commercial code applies to new construction as well as any work done on existing buildings, but only to new construction of 1-2 family residences. Residential sprinkler requirements have been pushed back until January 1, 2013.
