Housing & Infrastructure in Rio Verde
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
Housing age matters for water quality because lead solder was widely used in plumbing until the 1986 federal ban. Rio Verde's median build year of 1993 suggests a majority of homes were constructed under the newer standard — a meaningful factor when assessing household-level lead risk from tap water.
Most homes in Rio Verde were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Rio Verde Homeowners
Given current Rio Verde valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Rio Verde are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 154% above the Arizona average.
Lead Exposure Risk for Children in Rio Verde
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.
Since the federal solder ban took effect, new plumbing has been built without that pathway, and Rio Verde's pre-rule stock at 20% reflects a contained footprint.
