Housing Age Profile
Lake City's housing stock skews relatively recent, with a median build year of 1994. Homes constructed after 1986 avoid the lead-soldered copper joints that were standard before the federal ban — reducing aggregate risk from plumbing as a contamination pathway.
Most homes in Lake City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
