Two code zones, one window zone in South Dakota
South Dakota is split on the building code map but not on the window map. PNNL's county guide for the Department of Energy, PNNL-33270 (2021 county data), assigns 48 South Dakota counties to IECC zone 6A and the other 18 to zone 5A. Zone 6 is the colder of the two, and the letter A is DOE's label for moist.
ENERGY STAR, by contrast, places the entire state in its Northern zone on the window climate zone map (August 2025). For a window buyer the product criteria are the same in every county, while any code question depends on which IECC zone the county is in.
What DOE lists for South Dakota's residential code
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
The Building Energy Codes Program page for South Dakota (checked October 7, 2026) lists the 2009 IECC in the residential column, adopted March 15, 2011 and effective July 1, 2011, with no state amendments. The commercial column reads "None Statewide." For the use of the REScheck compliance tool, the page says "Applicable by County or Jurisdiction."
Buyers selling to installers in several South Dakota towns can ask each installer how its county or city handles the residential code.
South Dakota homes by age and value
Close to half of South Dakota's housing dates from before 1980. Table B25034 (ACS 5-year 2020-2024) puts 49.7% of units before 1980, and the median year built in table B25035 (ACS 5-year 2020-2024) is 1980.
The oldest band is the largest. The same table B25034 (ACS 5-year 2020-2024) counts 64,494 South Dakota units built in 1939 or earlier, ahead of every later decade in the table. A request from a house of that age may involve original wood windows or openings that are not standard sizes, which is why buyers ask for the year built.
Home values are moderate: table B25077 (ACS 5-year 2020-2024) puts the median value of an owner-occupied South Dakota home at $257,400.
The South Dakota tax license that covers window installers
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
South Dakota's state-level requirement for contractors runs through the Department of Revenue. Its fact sheet, License Requirements for Sales, Use and Contractor's Excise Tax (August 2025), says the contractor's excise tax is 2% of the gross receipts of prime contractors on construction services or realty improvement projects in the state, that the license has no fee, and that the license is required regardless of the amount of receipts or tax due.
The sheet lists construction, building, installation, repair and remodeling of real property as construction services. Who needs the license, and the state's door-to-door sales rule, are summarized on leads in South Dakota.
Filters South Dakota window buyers use
A South Dakota window campaign is usually built from four fields:
- ZIP code: buyers choose ZIP codes, which also places each job in an IECC zone and county.
- Home age: the large pre-1940 band above makes year built a useful question.
- Number of windows and scope: a few broken units or a whole-house replacement.
- Homeowner status: the owner is the person who signs the window contract.
