Housing Age Profile

The story of Johnson Creek's housing stock is one of layered development - neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1996 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards - creating a risk environment that the city-wide aggregate water data doesn't fully capture.

Most homes in Johnson Creek were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
