Housing Age Profile
With a median build year of 1983, Saint Leonard's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 - the year lead solder in plumbing was federally banned - meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Saint Leonard were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
