Housing & Infrastructure in New Castle
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
For most of New Castle's housing stock, construction occurred after 1986 — when lead solder in plumbing was federally prohibited. The median build year of 1992 broadly reflects that newer profile.
Most homes in New Castle were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for New Castle Homeowners
Within the New Castle market, estimated remediation claims a small portion of typical property equity — the financial burden is proportionally low.
Remediation costs in New Castle are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 4% above the Colorado average.
Lead Exposure Risk for Children in New Castle
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.
Once federal rules removed lead-bearing solder from new plumbing, building practice changed quickly. New Castle now carries just 29% of older inventory from that earlier era. Citywide readings remain compliant, though no system-level number can replace a one-home draw.
