In the United States, lead-based paint for homes was effectively phased out in the late 1970s, with a nationwide ban on its use in residential properties taking effect in 1978. However, it can still be present in older buildings, especially those built before that year.

Key dates in the U.S.

  • Lead-based paint was widely used in homes through the early and mid‑20th century because it was durable and resisted moisture.
  • Growing evidence of lead poisoning, especially in children, led to federal action in the 1970s.
  • A comprehensive federal ban on manufacturing and selling lead-based house paint for residential use took effect in 1978, which is why homes built after 1978 are generally considered much lower risk for original lead paint on walls and trim.

Why it still matters today

  • Many homes built before 1978 still have layers of old lead paint under newer coatings, and it becomes hazardous when it peels, chalks, or is disturbed during renovations.
  • Lead dust and chips from deteriorating or sanded paint can cause serious health problems, particularly for children and pregnant people, including developmental delays and neurological damage.

Quick safety tips

  • If a home was built before 1978 and paint is cracking or renovations are planned, it is safer to assume lead may be present and use certified lead-safe contractors for testing and removal.
  • Dry sanding or scraping painted surfaces in older homes without proper containment and protection should be avoided because it can release large amounts of lead dust.
