How Old Is Knotts Island'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
Because Knotts Island's housing stock spans a wide range of construction eras, the median build year of 1996 lands in a zone where two distinct risk populations share the same residential market. Homes built before 1986 may have lead-soldered copper plumbing joints - that practice was federally prohibited in 1986 but remained standard until then. The fraction built before 1970 face an additional risk: lead pipes used for service line connections were common before that decade, meaning both the pipe and the solder may be lead-containing in the oldest structures. Residents in mid-century or earlier homes face a different risk environment than neighbors in houses built after 1986, even if they drink from the same utility's supply - and that property-level divergence is what makes the age distribution above more diagnostic than the city-wide median alone.
Most homes in Knotts Island were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Knotts Island: Remediation Cost in Perspective
At current valuations, Knotts Island sits in the low remediation-share tier - the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Knotts Island are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 0% above the North Carolina average.
Protecting Children from Lead in Knotts Island
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.
34% - that captures the slice of Knotts Island housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Historical Flood-Claim Evidence for Knotts Island
Historical NFIP data for Knotts Island contains 38 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $11,170. 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>$1,200</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.
