Homes in North Sioux City at a glance

The newest housing in the metro
North Sioux City is the newest town on this site by its housing. Half the homes were built in 1997 or later, and only about a third before 1980. It also has the largest share of apartments and townhomes: only about 39% of homes are single-family detached houses, and about half are rented.
Heating is split nearly evenly: about 49% of homes burn natural gas and 47% heat with electricity.
What that means for the systems
- Heat pumps and electric furnaces are common in newer construction with electric heat. Ask whether the system has backup heat, because at 0°F and below — about 16 nights a year here (NOAA 1991–2020 normals) — a heat pump leans on it.
- First replacements. Equipment installed when these homes were built is now well into its second decade.
- Townhomes and condos. In attached housing, the outdoor unit may sit in a shared area, and an association may have rules about replacing it. Check before the installer quotes.
