ANALYSIS
Statutes interpreted:
Statutory authority:
Explanation of agency authority:
Section 227.11 (2) (a), Stats. authorizes the Department to promulgate rules interpreting any statute that is enforced or administered by the Department, if the rule is considered necessary to effectuate the purpose of the statute. Section 101.63 (intro.) and (1) (intro.), Stats. require the department to adopt rules which establish standards for the construction and inspection of one- and two-family dwellings, and s. 101.63 (5) Stats. requires the department to review the rules adopted under this subchapter once every 3 years. No set of rules may be adopted that has not taken into account the costs of specific code provisions to home buyers in relationship to the benefits derived from the provisions. Related statute or rule:
Various other rules promulgated by the Department in chs. SPS 321 to 325 address construction of one- and two-family dwellings. Plain language analysis:
Currently, the Uniform Dwelling Code requires that natural light be provided in habitable rooms above the ground floor. The proposed regulations exempt rooms over garages from this natural light requirement.
Summary of, and comparison with, existing or proposed federal regulation:
Federal regulations do not provide provisions for construction of one- and two-family dwellings other than those for Housing and Urban Development (HUD) manufactured homes and those related to accessibility. No proposed federal regulations were found specifically related to rooms over garages or natural light provisions.
Comparison with rules in adjacent states:
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.
