Housing Age Profile
Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 2006, much of Ardenvoir's housing falls on the safer side of that line — though homes built before 1986 still warrant testing regardless of the city-wide profile.
Most homes in Ardenvoir were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
