How Old Is Mattapan's Housing Stock?
With 84% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Mattapan's housing stock is predominantly older, with a median build year of 1940 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here - a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.
Over half of homes in Mattapan were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mattapan: Remediation Cost in Perspective
Low proportionality - that's the Mattapan picture when remediation costs are placed against typical home equity.
Remediation costs in Mattapan are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 8% below the Massachusetts average.
Protecting Children from Lead in Mattapan
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.
84% of Mattapan housing dates to the pre-rule era, alongside aggregate readings hovering at the federal action mark - household-level confirmation through a draw-test kit fits the local picture.

Historical Flood-Claim Evidence for Mattapan
Historical NFIP data for Mattapan contains 15 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $8,001. 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.
