Homes and their age

The 2020 to 2024 American Community Survey (table B25035) puts New Plymouth city's median year built at 1976 (margin of error: 4 years). Table B25034 estimates that 456 of the city's 750 housing units, about 61 percent, went up before 1980, and 177 of them before 1950. The margin of error on the unit total is 180, which is wide for a town this small, so treat the shares as rough. Houses of this age are where repiping, aging drain lines and worn fixtures come up most.

Cold snaps

For a guide to the cold, NOAA's 1991-2020 normals for the Emmett 2 E station show 6.3 days in October and 9.8 in April on which the low reached 32 degrees F or less. Those shoulder months are when hose bibs and outdoor lines tend to be forgotten. New Plymouth's own readings can differ from a station in another town.
