Housing Age Profile

Viewed through the lens of construction era, Rea is predominantly an older city - a median build year of 1962 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (43%) 1970–1986 (24%) Post-1986 (33%)

Over half of homes in Rea 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 Rea Homeowners

Property equity in Rea runs well ahead of estimated remediation costs - a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.

Median Home Value

$187,500

Est. Remediation

$1,200

Remediation as % of home value 0.6%

Remediation costs in Rea are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 7% above the Missouri average.

Lead Exposure Risk for Children in Rea

67%

Homes Built Before 1986

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.

Practically, the structural drivers in Rea - 67% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark - make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.
