How Old Is Longview's Housing Stock?

Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Viewed through the lens of construction era, Longview is predominantly an older city — a median build year of 1978 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Longview were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Longview: Remediation Cost in Perspective
How much of a Longview 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 Longview are relatively low compared to home values. The $950–$2,100 estimated range is a small fraction of median property value. Home values are 42% above the Illinois average.
Protecting Children from Lead in Longview
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 91% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Longview.

What You Can Do in Longview
