Lead paint is banned for residential use in the United States, but it is still legally used in several industrial applications. The Consumer Product Safety Commission prohibited lead-based paint in homes, furniture, and consumer products back in 1977, setting a maximum allowable lead content of 0.06 percent (later tightened to 0.009 percent). That ban, however, only covers surfaces people live with. On bridges, water towers, outdoor stadiums, and other steel infrastructure, lead-based coatings remain in widespread use today.
What the Residential Ban Actually Covers
The CPSC’s ban applies to paint and similar surface coatings on products that consumers use: interior and exterior house paint, coatings on toys, furniture, and anything children might come into contact with. Any paint or coating containing 0.009 percent or more lead by weight is classified as a banned hazardous product. This threshold is extremely low, essentially zero for practical purposes.
Products manufactured before the ban, though, are still everywhere. Toys made before 2009 and any painted surface in a home built before 1978 could contain lead. The CDC continues to track recalls of children’s products including clothing, stainless steel bottles, desks, toys, and jewelry for lead contamination, often in items imported from countries with weaker regulations.
Where Lead Paint Is Still Used Today
Lead-based coatings remain the preferred choice for protecting steel infrastructure exposed to weather. Two forms of lead pigment, white lead (a lead carbonate) and red lead (a lead oxide), produce thick, durable coatings that expand and contract with the metal underneath without cracking. They also resist corrosion from acid rain, air pollution, and salt. No residential alternative matches that combination of flexibility and chemical protection on structural steel.
The Federal Highway Administration estimates that 35 to 40 percent of steel structures in the U.S. are coated with lead-based paint, including roughly 90,000 bridges. Even new steel members are sometimes coated with lead paint before being placed into service. Water towers, electrical transmission towers, and outdoor stadiums also commonly receive lead-based protective coatings. For anyone working on or near these structures, this is a significant occupational exposure risk, and strict safety protocols govern how workers strip and reapply these coatings.
The Scale of Lead Paint in Older Homes
An estimated 34.6 million homes in the U.S., about 29 percent of all housing units, still contain lead-based paint applied before the 1978 ban. That paint doesn’t pose a problem as long as it stays intact. The danger comes when it deteriorates, chips, or gets disturbed during renovation. Sanding, scraping, or demolishing painted surfaces in a pre-1978 home can release lead dust that settles on floors, windowsills, and hands.
Children are most vulnerable because they absorb lead more readily than adults and are more likely to put contaminated hands or objects in their mouths. The CDC uses a blood lead reference value of 3.5 micrograms per deciliter to flag children whose levels are higher than most kids their age. That threshold was lowered from 5.0 in 2021 to catch more children earlier. At that level, the CDC recommends nutritional counseling focused on calcium and iron intake, developmental monitoring, and follow-up blood tests. At 45 micrograms per deciliter or higher, medication to remove lead from the body may be necessary.
Rules for Renovating Older Homes
If you’re renovating, repairing, or repainting a home built before 1978, the EPA’s Renovation, Repair and Painting (RRP) Rule requires that the work be done by certified firms using trained renovators who follow lead-safe work practices. This isn’t optional. Contractors must be certified, and the training programs they attend must be EPA-accredited. The goal is to control dust and debris so that renovation work doesn’t turn stable lead paint into an airborne hazard.
If you’re hiring someone to do work on an older home, ask for their EPA certification. If you’re doing the work yourself, you should still test painted surfaces before disturbing them.
How to Test for Lead Paint
Two main options exist: professional X-ray fluorescence (XRF) testing and DIY chemical swab kits. They differ dramatically in reliability.
- XRF analyzers are pressed against the painted surface and deliver results in 2 to 10 seconds per reading. They detect lead through multiple layers of paint, so even if lead paint is buried under five coats of newer paint, the device finds it. XRF testing is EPA-recognized, highly accurate, and legally defensible for real estate transactions and regulatory compliance.
- DIY swab kits require you to cut through the paint surface, apply a chemical solution, and watch for a color change. They only test the exposed layer, so lead hidden under newer coats can be missed entirely. They have higher false positive and false negative rates, give you no information about concentration, and are not accepted by the EPA for compliance or legal purposes.
For anything beyond casual curiosity, such as a home purchase, a renovation project, or concern about a child’s exposure, professional XRF testing is the more reliable path. DIY kits can give you a rough sense of whether lead is present on a visible surface, but a negative result doesn’t guarantee safety.
Global Use Varies Widely
While the U.S., the European Union, Canada, and Australia all restrict lead in residential paint, enforcement and regulation vary significantly across the rest of the world. Some countries still manufacture and sell lead-based house paint with no labeling requirements. Imported goods, particularly toys, ceramics, and painted furniture from countries without strict lead limits, remain a source of exposure even in nations with domestic bans. This is one reason product recalls for lead contamination continue to appear regularly.
