How Old Is Fresno'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 Fresno's housing inventory — median build year 2004 — generally signals lower aggregate plumbing-era lead risk.
Most homes in Fresno were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Fresno: Remediation Cost in Perspective
Because property values in Fresno comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Fresno are relatively low compared to home values. The $1,200–$2,500 estimated range is a small fraction of median property value. Home values are 5% above the Texas average.
Protecting Children from Lead in Fresno
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.
Whenever aggregate samples pass the federal action benchmark and pre-rule housing — 7% in Fresno — represents a smaller fraction, lead occupies a lower priority on the local picture.

Climate-Related Water Risk for Fresno
Within the NFIP's national dataset, Fresno falls in moderate-exposure territory — 94 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Fresno has a moderate flood history with 94 FEMA claims averaging $35,993 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>$1,800</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.

What You Can Do in Fresno
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
