Housing Age Profile
For a city with a median build year of 1983, Caddo Gap carries a housing profile that straddles the 1986 federal ban on lead solder in plumbing. Neither predominantly new nor predominantly old, the stock presents a moderate aggregate risk environment — with individual risk varying sharply depending on when and where a specific home was built.
Most homes in Caddo Gap were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Caddo Gap Homeowners
Given current Caddo Gap property values, the remediation share falls in the moderate tier — an indicator that the household financial perspective here calls for advance planning rather than dismissal, with most homeowners positioned to address documented issues through deliberate budgeting rather than needing to treat remediation as a significant equity event or financial emergency.
Remediation costs are moderate relative to home values in Caddo Gap. The estimated $1,200–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 13% above the Arkansas average.
Lead Exposure Risk for Children in Caddo Gap
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.
Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 46% of Caddo Gap stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.
