How Old Is Hammond's Housing Stock?

Built Before 1986

Copper
Likely Pipe Material

With 46% 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.

Housing Age Profile

Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1981 places Hammond in the middle zone between those thresholds - with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.

19%
Pre-1970 (Lead Pipes Risk)
Pre-1970 (19%) 1970–1986 (27%) Post-1986 (54%)

Most homes in Hammond were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Hammond: Remediation Cost in Perspective

When remediation costs are measured against Hammond home values, the resulting ratio is in the low tier - addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.

Median Home Value
$285,900
Est. Remediation
$2,400
Remediation as % of home value 0.8%

Remediation costs in Hammond are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 24% above the Wisconsin average.

Protecting Children from Lead in Hammond

Homes Built Before 1986
0.001
mg/L Avg Lead (Limit: 0.015)

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.

Pulling a tap sample fills the gap that utility data cannot close, particularly here where 46% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Hammond.

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>$2,400</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.
