How Old Is Natrona'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
Congress banned lead solder in residential plumbing in 1986, drawing a clear line in housing risk by era. Natrona's median build year of 2015 puts most of its residential stock on the newer side of that boundary — a profile that generally correlates with lower plumbing-sourced lead exposure across the city.
Most homes in Natrona were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
