This provision says when the state building code applies, including to certain state-owned, publicly funded, and larger city projects, and it requires cities in one category to enforce the code and the commissioner to grant exceptions when energy rules would be impractical.
1. The state building code shall, for the buildings and structures to which it is applicable, constitute a lawful local building code. 2. The state building code shall be applicable: a. To all buildings and structures owned by the state or an agency of the state. b. In each governmental subdivision where the governing body has enacted an ordinance accepting the application of the code. c. To all newly constructed buildings and structures the construction of which is paid for in whole or in part with moneys appropriated by the state but which are not wholly owned by the state. d. In each city with a population of more than fifteen thousand that has not adopted a local building code that is substantially in accord with standards developed by a nationally recognized building code organization. The city shall enforce the state building code, including the provisions in section 103A.19, subsection 2. 3. Provisions of the state building code relating to the manufacture and installation of factory-built structures shall apply throughout the state. A factory-built structure approved by the commissioner shall be deemed to comply with all building regulations applicable to its manufacture and installation and shall be exempt from any other state or local building regulations. Except with respect to manufactured homes, as defined in section 103A.51, subsection 4, a provision of this chapter relating to the manufacture or installation of factory-built structures shall not alter or supersede any provision of chapter 542B concerning the practice of professional engineering or chapter 544A concerning the practice of architecture. 4. Notwithstanding the provisions of section 103A.22, subsection 1: a. Provisions of the state building code establishing thermal efficiency energy conservation standards shall be applicable to all construction in the state which will contain enclosed space that is heated or cooled. The commissioner shall provide appropriate exceptions for construction where the application of an energy conservation requirement adopted pursuant to this chapter would be impractical. b. Provisions of the state building code establishing lighting efficiency standards shall be applicable to all construction in the state and to new and replacement lighting in existing buildings. 5. Notwithstanding any other provision of this chapter to the contrary, the energy conservation requirements adopted by the commissioner and approved by the council shall apply to all new construction commenced on or after July 1, 2008, and shall supersede and replace any minimum requirements for energy conservation adopted or enacted by the governmental subdivision prior to that date and applicable to such construction.
