How Old Is Trego's Housing Stock?
With 47% 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
With a median build year of 1981, Trego's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 — the year lead solder in plumbing was federally banned — meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Trego were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Trego: Remediation Cost in Perspective
Given current Trego valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Trego are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 6% below the Wisconsin average.
Protecting Children from Lead in Trego
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.
When older housing represents 47% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Trego address.
