Housing Age Profile
For a city with a median build year of 1996, Saint Landry 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 Saint Landry were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.
