How Old Is Dublin'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
Federal restrictions on lead pipe, solder and flux in new drinking water plumbing date from the 1986 Safe Drinking Water Act amendments; the median build year of 2007 for Dublin is one reference point against that date.
Most homes in Dublin were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Historical Flood-Claim Evidence for Dublin
Historical NFIP data for Dublin contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,963. 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 $500 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.
