How Old Is Joinerville's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Post-1986 construction is where the lower lead-solder risk lives, because that's when the federal ban on lead solder in plumbing took effect. In Joinerville, where the median build year is 2005, the housing stock falls broadly on the newer side of that threshold — a distribution that moderates aggregate plumbing-era risk compared to older housing markets.
Most homes in Joinerville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
