Lancaster Housing Stock
Half the homes in Lancaster were built before 1938 (Census ACS median), so the typical house is about 88 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. About 10,000 households here own their home, 47.5% of the occupied total. Homes here have a median value of $203,700 and households a median income of $63,421. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Lancaster County show 12 hail days and 54 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.5 inches across.
