Key takeaways
Lead paint is an age-of-home problem with a child-health core: it is nearly universal in homes built before 1940, rare in those built after the 1978 ban, and the reason it still matters is that no blood lead level in children is considered safe. Removal costs a few thousand dollars, but intact paint is often safest sealed rather than stripped.
87% of US homes built before 1940 have some lead-based paint.
Lead paint removal averages about $3,499 ($1,478 to $5,520).
About 500,000 US children have blood lead at or above the CDC reference value.
The CDC states there is no safe blood lead level in children.
Residential lead paint was banned in 1978; disclosure is required for older homes.
How we built this report
Every figure below was compiled in September 2026 from named public sources and checked against the original document before publishing.
- Government sources for all health data
Prevalence figures come from the EPA and blood-lead figures from the CDC. We use the CDC's current reference value (3.5 micrograms per deciliter) and note it is a population marker, not a health-based safety threshold.
- Only explicitly stated figures
We include only numbers a named source states directly, and attribute each inline at the point it appears.
- Health and cost kept separate
Prevalence and blood-lead figures come only from the EPA and CDC; dollar costs come only from the cost guide. We do not blend the two.
- Independent review
Written by one co-founder and reviewed by the other before publishing.
Scope note: prevalence figures are EPA estimates by construction era; the CDC blood lead reference value is a population marker (the 97.5th percentile), not a regulatory or health-based safety threshold. Cost figures are guide-level national ranges and vary by method, surface, and home size. Confirm any single figure against the specific source before relying on it, and use an EPA-certified professional for any work in a pre-1978 home.
Lead paint in US homes, by the numbers
All 20 figures, grouped into four themes: where lead paint is found, the child blood-lead picture, what removal costs, and inspection and abatement methods. Each is drawn from a named public source and independently verified.
Where lead paint is found
Lead paint prevalence is almost entirely a function of when a home was built. According to the US Environmental Protection Agency (epa.gov), 87% of homes built before 1940 have some lead-based paint, falling to 24% of those built between 1960 and 1978. Residential lead paint was banned in 1978, and federal law (Title X) requires disclosure of known lead-based paint before the sale or lease of most housing built before then, which is why a lead disclosure is now part of most older-home transactions.

What this means: Home age is the single best predictor of lead-paint risk. A pre-1940 home should be assumed to contain lead paint until tested, while a post-1978 home effectively does not, which makes the build year the first question in any older-home purchase or renovation.
The child blood-lead picture
Lead's danger is concentrated in young children. According to the CDC (cdc.gov), there is no safe blood lead level in children, and even low levels cause harm. The CDC uses a blood lead reference value of 3.5 micrograms per deciliter to flag children above the 97.5th percentile; about 2.5% of children aged 1 to 5, roughly 500,000 children, are at or above it. The long-run trend is one of the great public-health successes: in 1976-1980, 88.2% of children 1 to 5 had blood lead at or above 10 micrograms per deciliter, a level almost no child reaches today.

What this means: The removal of lead from gasoline and paint drove one of the largest environmental-health improvements on record, but the reference value keeps dropping precisely because no level is safe. The remaining exposure is concentrated in older housing, where deteriorating paint and dust are the pathway.
What removal costs
Removal cost scales with area and method. According to HomeAdvisor (homeadvisor.com), lead paint removal averages $3,499, with most homeowners spending $1,478 to $5,520; small jobs start around $800 and whole-house abatement can reach $11,600. Manual removal runs $8 to $17 per square foot, so cost climbs quickly with the size of the home, from a few thousand dollars for a single room to tens of thousands for an entire house.

Statistic 14
Demolition and replacement of lead-painted components runs $10,000 to $15,000.
HomeAdvisor (2026)
What this means: Because manual removal is priced per square foot and dominated by labor, the total is really a function of how much lead-painted surface a home has. That is what makes the cheaper in-place options below worth considering when paint is intact.
Inspection and in-place methods
Testing is cheap and the decision it informs often favors leaving intact paint alone. According to HomeAdvisor (homeadvisor.com), a lead inspection with a certified inspector runs $200 to $400. Two in-place methods cost far less than removal: encapsulation, sealing the paint with a specialized coating, runs $4 to $8 per square foot, and enclosure, covering it with a new surface, $9 to $10 per square foot. Intact, well-maintained lead paint is lower risk than the dust created by disturbing it, which is why a test before any renovation is the pivotal step.

Statistic 20
Encapsulation at $4 to $8 per square foot is roughly half the cost of manual removal at $8 to $17 per square foot.
HomeAdvisor (2026)
What this means: For intact paint, encapsulation or enclosure at a fraction of removal cost is often the recommended course, and a $200 to $400 inspection is what tells a homeowner which path applies before a renovation disturbs anything.
