Housing & Infrastructure in Crown King
With 72% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Crown King's median build year of 1973 places it squarely in that category.
Over half of homes in Crown King were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Crown King Homeowners
In Crown King, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Crown King are relatively low compared to home values. The $150–$1,400 estimated range is a small fraction of median property value. Home values are 43% above the Arizona average.
Lead Exposure Risk for Children in Crown King
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older stock in Crown King represents 72% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
