Housing Age Profile
Some cities skew heavily toward one construction era; Trinity does not. The median build year of 1998 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk — with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.
Most homes in Trinity were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Trinity
In Trinity, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Trinity are relatively low compared to home values. The $1,100–$2,300 estimated range is a small fraction of median property value. Home values are 16% above the Alabama average.
Trinity: Lead Risk & Vulnerable Populations
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 Trinity — 43% 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.
