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.
