How Old Is Sahuarita'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
A post-1986 majority in Sahuarita's housing inventory — median build year 2005 — generally signals lower aggregate plumbing-era lead risk.
Most homes in Sahuarita were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Sahuarita: Remediation Cost in Perspective
Across Sahuarita, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Sahuarita are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 3% above the Arizona average.
Protecting Children from Lead in Sahuarita
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.
Although citywide aggregate readings pass cleanly and just 9% of Sahuarita housing comes from the pre-rule era, the difference between what utilities sample and what arrives at one specific faucet remains a structural feature of how monitoring works. Households with kids in the home can find a certified lead-removal filter and a draw-test kit through retailer-verified channels. That step is independent of system-level data.

Climate-Related Water Risk for Sahuarita
Measured across the NFIP's multi-decade tracking period, Sahuarita shows a moderate flood record — 6 claims and 100% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Sahuarita has a moderate flood history with 6 FEMA claims averaging $6,000 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$1,600</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
