Milwaukee Housing Stock
The median Milwaukee home dates to 1952, according to the Census ACS. That makes the typical house about 74 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. Milwaukee has roughly 96,000 owner-occupied homes, or 41.5% of households. Homes here have a median value of $172,000 and households a median income of $51,888. Those two numbers drive the labor adjustment in our estimate.
Milwaukee County had 19 hail days and 19 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across.
