How Old Is Lewisville's Housing Stock?
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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Lewisville's median build year of 1982 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on - and whether it predates 1970 - is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Lewisville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lewisville: Remediation Cost in Perspective
For most homeowners in Lewisville, the estimated cost of water and safety remediation represents a proportionally modest share of what properties are worth - placing this area in the lower tier of the remediation share scale.
Remediation costs in Lewisville are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 34% above the North Carolina average.
Protecting Children from Lead in Lewisville
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 46% 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 Lewisville address.
