How Old Is Gray Mountain's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Gray Mountain's median build year of 1998 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Gray Mountain were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Gray Mountain: Remediation Cost in Perspective
The cost-to-value ratio in Gray Mountain is in the moderate range — neither dismissible nor alarming, but above the threshold where remediation can be treated as incidental. Most homeowners here are weighing a real equity commitment, and the moderate classification reflects that accurately.
Remediation costs are moderate relative to home values in Gray Mountain. The estimated $0–$800 range is manageable for most homeowners but still worth budgeting for. Home values are 90% below the Arizona average.
Protecting Children from Lead in Gray Mountain
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 34% pre-rule share in Gray Mountain keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
