Chino Infrastructure Age
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 is a practical proxy for plumbing risk because federal standards changed in 1986, when lead solder was banned from new residential construction, and again earlier - before 1970, lead pipes were themselves commonly installed. Chino's median build year of 1986 sits in the range where both pre- and post-1986 homes are well represented. The bar chart above reflects that mixed picture: the distribution captures pockets of older housing alongside more recent development, and those pockets carry real lead risk potential at the individual property level.
Most homes in Chino were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Chino
In Chino, property wealth outpaces what documented remediation typically demands - the equity burden lands well within the low tier.
Remediation costs in Chino are relatively low compared to home values. The $750–$2,700 estimated range is a small fraction of median property value. Home values are 13% below the California average.
Chino: Lead Risk & Vulnerable Populations
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 Chino represents 34% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.

Chino: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Chino contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $1,200. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$1,600</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
