Sioux City Housing Stock
Census figures put the median build year in Sioux City at 1956, so a typical house here has about 70 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Sioux City has roughly 22,000 owner-occupied homes, or 65.5% of households. With a median household income of $65,473 and a median home value of $162,600, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 14 hail days and 24 days with damaging thunderstorm winds in Woodbury County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Woodbury County also had 2 tornado days in that period.
