Illinois: An Internet-based search did not reveal the existence of a statewide one- and two-family dwelling code. Dwelling regulation appears to be left up to the individual local units of government.
Iowa: An Internet-based search revealed that the Iowa Building Code adopts the 2009 International Residential Code (IRC) and 2009 International Energy Conservation Code (IECC). The Iowa Building Code applies statewide to state owned and funded buildings. The accessibility, energy conservation, and minimum plumbing provisions apply to dwellings statewide. The 2009 IRC requires natural light in all habitable rooms of residences except if certain lighting and mechanical ventilation criteria are met and the room is not used for sleeping.
Michigan: An Internet-based search revealed a mandatory, statewide one- and two-family dwelling code. The Residential Construction Code under the Construction Code Commission’s General Rules, in section 408.305, contains the state amendments to the 2009 International Residential Code developed by the International Code Council. The 2009 IRC requires natural light in all habitable rooms of residences except if certain lighting and mechanical ventilation criteria are met and the room is not used for sleeping.
Minnesota: An Internet-based search revealed a mandatory, statewide one- and two-family dwelling code. The Minnesota Department of Labor and Industry, in Chapter 1309, adopts by reference Chapters 2 through 10, 44, Section P2904 and Appendix K from the 2012 IRC as amended in Minnesota. Chapters 2-10 contain the general construction provisions of the IRC. Natural light is required in all habitable rooms of residences except if certain lighting and mechanical ventilation criteria are met and the room is not used for sleeping. Summary of factual data and analytical methodologies:
The Department received input during meetings with the Dwelling Code Council. The makeup of this Council is established under section 15.407 (10) of the Statutes and consists of members who are appointed by the Governor. The Council includes representatives of several types of small businesses. These businesses provide input on design, construction, and inspection interests relative to the Uniform Dwelling Code. Through this Council, the Department was able to gather information on the potential impacts of the rule revisions contained herein. ------------------------------------------------------------------------------------------------------------
