Housing Age Profile
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 2009 places Coalmont in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
A significant portion of Coalmont's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Pulling a tap sample fills the gap that utility data cannot close, particularly here where 44% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Coalmont.
