Waterbury Housing Stock
The median Waterbury home dates to 1959, according to the Census ACS. That makes the typical house about 67 years old. 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. Waterbury has roughly 21,000 owner-occupied homes, or 45% of households. With a median household income of $51,642 and a median home value of $185,400, local labor rates come out below the national middle in our model.
