July 1, 2015 The design standard for any new construction commenced after this date within the boundaries of any local unit of government that has not adopted an ordinance prescribing standards for new construction pursuant to § 11-10-5 shall be based on the 2015 IBC. Each local unit of government may adopt an ordinance allowing local administration and enforcement of the design standard. The provisions of this section do not apply to new construction for any one or two family dwelling, mobile or manufactured home, townhouse, or farmstead and any accessory structure or building thereto.
July 1, 2011 Senate Bill 94 becomes effective, making the 2009 IECC the effective voluntary energy standard for new residential construction. SB 94 was signed into law on March 15, 2011.

This legislation also accordingly updates the state’s required disclosure form for prospective homebuyers regarding information about the energy efficiency of the new residential building.

July 1, 2009 The legislature passes Senate Bill 64, making the 2006 IECC effective as the adopted voluntary standard for new residential buildings. Any builder or seller of a previously unoccupied new residential building which is a single-family or multifamily unit of four units or less shall disclose to the buyer or prospective buyer information regarding the energy efficiency of the residential building.
1978 The South Dakota building code is first enacted, with an energy code as part of Chapter 53 of the state building code. However, only three jurisdictions adopt the energy code portion of the state building code. As of 1994, no jurisdictions actively enforce the energy code portion of the state building code.
