How Old Is Hanover'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
Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 2006, much of Hanover's housing falls on the safer side of that line - though homes built before 1986 still warrant testing regardless of the city-wide profile.
Most homes in Hanover were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Hanover: Remediation Cost in Perspective
How much of a Hanover home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.
Remediation costs in Hanover are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 76% above the Minnesota average.
Protecting Children from Lead in Hanover
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.
Despite citywide averages reading cleanly under the federal action threshold, the way utilities pull samples - from a representative subset rather than door-to-door - leaves room for individual buildings with older interior lines to behave differently than the aggregate suggests. With only 20% of Hanover stock predating the solder rule, that residual subset is small but real, and a draw-test kit gives the only direct read on what comes out of one faucet on a given morning.
