Cold climate zones across Minnesota
Nearly every Minnesota county falls in IECC zone 6A or zone 7. The county guide DOE commissioned from PNNL, PNNL-33270 (2021 county data), puts 61 counties in zone 6A, 23 northern counties in zone 7 and only 3 counties in zone 5A. DOE marks zones 5A and 6A with the letter A for moist climates; zone 7 carries no moisture letter.
For window products the state is simpler. On the ENERGY STAR climate zone map (August 2025), every Minnesota county is in the Northern zone, so one set of ENERGY STAR window criteria applies to every ZIP code a buyer selects in the state.
Minnesota license law and window work
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.
Minnesota names window work in its contractor statute. Minnesota Statutes 326B.802 (checked October 7, 2026) sorts residential work into eight special skills, and the carpentry skill lists "doors, windows, and skylights" next to rough framing and finish carpentry. A company that offers two or more special skills to an owner meets the definition of a residential remodeler or residential building contractor.
The licensing section, Minnesota Statutes 326B.805 (checked October 7, 2026), requires those remodelers and contractors to hold a license from the commissioner. Its exemption list includes specialty contractors who provide only one special skill. Subdivision 1a adds a rule for older housing: a licensee performing renovation, as the federal lead rule at 40 CFR 745.83 defines it, on a residential structure built before 1978 must comply with section 326B.106, subdivision 14.
Roofer licensing, the home solicitation cancellation rule and the rest of the state overview are on leads in Minnesota.
How old Minnesota homes are
About half of the state's housing predates 1980. Table B25034 (ACS 5-year 2020-2024) puts 52.1% of Minnesota housing units in that group, and the same table counts 395,770 units built in 1939 or earlier. The median year built in table B25035 (ACS 5-year 2020-2024) is 1979, the year right after the 1978 line in the renovation rule above.
The median value of an owner-occupied Minnesota home is $329,300 in table B25077 (ACS 5-year 2020-2024). Window buyers who quote by project size can pair that figure with the number of openings a homeowner reports.
The energy code Minnesota has adopted
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.
Minnesota's residential energy code is older than its commercial one. The DOE Building Energy Codes Program page for Minnesota (checked October 7, 2026) shows the 2012 IECC with amendments for homes, adopted December 8, 2014 and effective February 14, 2015, while commercial buildings follow ASHRAE 90.1-2019 with amendments.
Filters Minnesota window buyers set
Each filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary below links back to a Minnesota fact on this page.
- Home age: the 1978 line in the renovation rule makes the approximate build year a useful field.
- Number of windows and scope: window-only work versus a job that adds siding or framing, which changes how many special skills a crew provides.
- Homeowner status: the owner is the party a licensed remodeler contracts with.
- ZIP code: buyers choose ZIP codes by service area, including the zone 7 counties in the north.
Where buyers filter in Minnesota
Crews in Minnesota usually cover the Twin Cities or one regional center. These are the six largest metro areas that include Minnesota counties, from the Census Bureau's July 1, 2025 estimates. Three of them cross into Wisconsin or North Dakota, so their figures cover the whole metro area, and ZIP code filters can keep a campaign on the Minnesota side.
- Minneapolis-St. Paul-Bloomington, MN-WI: 3,790,295 (July 1, 2025 estimate, whole metro area)
- Duluth, MN-WI: 281,219 (July 1, 2025 estimate, whole metro area)
- Fargo, ND-MN: 269,528 (July 1, 2025 estimate, whole metro area)
- Rochester: 231,184 (July 1, 2025 estimate)
- St. Cloud: 205,854 (July 1, 2025 estimate)
- Mankato: 104,907 (July 1, 2025 estimate)
