Lead Paint Was Outlawed in 1978: What the Ban Covered
Lead-based paint was outlawed in the United States in 1978. The federal rule came from the Consumer Product Safety Commission, was published on August 27, 1977, and took effect on February 27, 1978. It is codified at 16 CFR Part 1303, and it did more than discourage lead paint: it made manufacturing, selling, and applying it to homes and children’s products a federal violation carrying civil and criminal penalties.
That one-word answer hides the part that actually matters to anyone who owns an older house. The ban stopped new lead paint. It never touched the lead paint already on the walls of tens of millions of existing homes. Understanding exactly what 1978 did and did not do is the difference between assuming your pre-1978 house is fine and knowing where the real risk sits.

What the 1978 rule actually prohibited
The CPSC rule set a ceiling of 0.06 percent lead by weight in the dried paint film and banned four things above that limit:
- Manufacturing paint for consumer or residential use.
- Selling or distributing it through wholesalers and retailers.
- Applying it to residential interior or exterior surfaces.
- Using it on toys and children’s furniture — the most pointed pediatric-protection language in the rule.
The limit applies to imported paint too, so foreign-made lead paint cannot legally enter the U.S. consumer market either. In 2009, under the Consumer Product Safety Improvement Act, the threshold was tightened roughly sixfold, from 0.06 percent down to 0.009 percent by weight. The CPSC still issues recalls most years for imported toys and products found with non-compliant coatings, which is why the ban is best understood as a live enforcement program, not a one-time historical event. The EPA lead program documents the current regulatory chain.
What the ban left legal
The 1978 rule was aimed at consumer and residential paint. Several categories were left outside it:
- Industrial and structural coatings. Lead paint stayed legal for bridges, steel structures, and ship hulls, where corrosion resistance mattered and worker exposure could be controlled under OSHA rules. Many of these surfaces carried lead coatings for decades after 1978.
- Military and aerospace uses where performance specifications had no qualified lead-free substitute. These exemptions narrowed over time but were never fully eliminated.
- Specialty artists’ oil paints, such as lead-carbonate flake white, which remain legal for studio use but are barred from children’s art supplies and must carry warnings.
The most important exclusion for homeowners is the simplest one: the rule never required anyone to remove lead paint that was already there. According to EPA and HUD survey data, roughly 30 million U.S. homes still contain lead-based paint, and about 24 million of those have deteriorating paint or lead-contaminated dust. If your house predates 1978, the ban says nothing about whether lead is in it — only that no new lead paint should have gone on after that date.
Why lead paint was banned when it was
Lead was added to paint for good technical reasons: as a bright, opaque white pigment (lead carbonate), as yellows and reds (lead chromate and tetroxide), as a rust inhibitor on metal, and as a drier that sped up curing. It genuinely performed well, which is why it dominated for over a century before the health cost was widely understood.
By the 1970s the evidence was undeniable. Lead-paint dust from friction surfaces — windows, doors, stairs — becomes ingestible by young children through ordinary hand-to-mouth behavior, and researchers had firmly linked childhood blood lead to lower IQ, attention problems, and developmental harm. As leaded gasoline was phased out, residential paint became the dominant pediatric exposure pathway. The CDC has since lowered its threshold repeatedly; the current CDC blood lead reference value is 3.5 micrograms per deciliter, and the agency states there is no known safe level of lead in a child’s blood. The National Institute of Environmental Health Sciences reaches the same conclusion on low-dose exposure.
The rules that came after 1978
Because the 1978 ban ignored existing paint, Congress and federal agencies built a second layer of regulation to manage the in-place hazard:
- 1992 — Title X (Residential Lead-Based Paint Hazard Reduction Act) created the framework for disclosure and renovation safety in pre-1978 housing.
- 1996 — EPA/HUD Disclosure Rule requires sellers and landlords of pre-1978 housing to disclose known lead hazards and hand over the EPA “Protect Your Family From Lead in Your Home” pamphlet before a sale or lease.
- 2000 — HUD Lead Safe Housing Rule applies lead-safe practices to federally assisted pre-1978 housing.
- 2010 — EPA Renovation, Repair and Painting (RRP) Rule requires that firms disturbing paint in pre-1978 homes use EPA-certified renovators and lead-safe work practices, because renovation dust is what actually poisons children.
The HUD Office of Lead Hazard Control administers much of this framework. If you are buying or selling, the disclosure obligation is the one you’ll meet first — we cover the mechanics in when a lead-based paint disclosure is required.
What this means if you own a pre-1978 home
Put the dates together and the practical rule is simple. Paint applied after 1978 should be lead-free. Paint under it may not be. The hazard is not intact, well-maintained paint sitting quietly on a wall — it is paint that is chipping, peeling, chalking, or being disturbed by sanding and demolition.
Consider testing (an XRF scan or lab paint-chip analysis) before any substantial renovation of a pre-1978 house, if a young child or pregnant woman lives there, or if you see deteriorating paint. That advice applies as squarely to the older brick bungalows of Denver, Boulder, and central Colorado Springs as it does anywhere else, since much of the Front Range’s pre-war housing stock is exactly the vintage the ban left untouched.
