How Old Is San Ramon'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
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In San Ramon, the median build year of 1998 indicates that plumbing age is a material factor in local lead risk - with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in San Ramon were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

San Ramon: Remediation Cost in Perspective
For most homeowners in San Ramon, the estimated cost of water and safety remediation represents a proportionally modest share of what properties are worth - placing this area in the lower tier of the remediation share scale.
Remediation costs in San Ramon are relatively low compared to home values. The $1,200–$3,550 estimated range is a small fraction of median property value. Home values are 109% above the California average.
Protecting Children from Lead in San Ramon
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 interior plumbing shapes the local picture: 39% of San Ramon homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Historical Flood-Claim Evidence for San Ramon
Historical NFIP data for San Ramon contains 23 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $45,095. Among ZIP codes with claim records, 100% 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>$2,000</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.
