Housing & Infrastructure in Caddo
With 54% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Caddo's median build year of 1986 places it squarely in that category.
Over half of homes in Caddo were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Caddo Homeowners
The household financial picture for Caddo homeowners is proportionally favorable — addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.
Remediation costs in Caddo are relatively low compared to home values. The $450–$1,400 estimated range is a small fraction of median property value. Home values are 4% below the Oklahoma average.
Lead Exposure Risk for Children in Caddo
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.
Older stock in Caddo represents 54% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
