Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Crown City, the median build year of 1981 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Crown City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
