Was Asbestos Really Banned? The Truth About Asbestos in American Buildings

If you've ever been told that your home or building "doesn't need asbestos testing because it was built after 1980," you've been given dangerously inaccurate advice. The belief that asbestos was banned in the United States decades ago is one of the most persistent and potentially harmful misconceptions in property ownership and construction today.

The reality is far more nuanced—and understanding it could protect your family, your employees, or your investment.

The 1989 Ban That Wasn't

In 1989, the U.S. Environmental Protection Agency (EPA) issued a final rule under the Toxic Substances Control Act (TSCA) that would have phased out and banned most asbestos-containing products in the United States. For a brief moment, it appeared that the country was finally taking decisive action against a substance known to cause lung cancer, mesothelioma, ovarian cancer, and laryngeal cancer.

That moment was short-lived.

In 1991, the Fifth Circuit Court of Appeals largely struck down the EPA's ban in Corrosion Proof Fittings v. EPA (947 F.2d 1201). The court ruled that the EPA had not adequately demonstrated that a ban was the least burdensome alternative for addressing asbestos risks. The decision didn't just overturn the 1989 rule—it effectively crippled the EPA's ability to regulate existing chemicals under TSCA for the next 25 years.

Only a handful of specific product bans survived the court's ruling: new uses of asbestos that didn't exist before 1989, flooring felt, rollboard, and certain types of commercial and specialty paper. Everything else—roofing materials, gaskets, brake pads, cement products, clothing, and dozens of other product categories—remained perfectly legal.

What the 2024 Ban Actually Covers

In March 2024, the EPA finalized a new rule banning ongoing uses of chrysotile asbestos, the only form of asbestos currently known to be imported into and used in the United States. This was the first rule finalized under the 2016 amendments to TSCA, and it was widely reported as a historic milestone.

And it is—but with important caveats that most news coverage glossed over.

The 2024 ban specifically targets chrysotile asbestos in products that were still actively manufactured or imported: asbestos diaphragms used in the chlor-alkali industry, sheet gaskets, brake blocks, aftermarket automotive brakes and linings, and other vehicle friction products. The chlor-alkali industry—which uses asbestos diaphragms to produce chlorine for water treatment—was given a transition period of five to twelve years to phase out asbestos use entirely.

Here's what the 2024 ban does not do:

It does not address the millions of buildings across America that already contain asbestos-containing materials. It does not ban all six types of regulated asbestos fibers—only chrysotile. And critically, it does not retroactively make older buildings safe. The asbestos that was legally installed in your walls, floors, ceilings, insulation, and roofing over the past century is still there.

Why Building Age Is Not a Reliable Indicator

This is where the misconception becomes genuinely dangerous. Many homeowners, real estate agents, and even some contractors operate under the assumption that buildings constructed after 1980 (or 1985, or 1990—the date varies depending on who's giving the advice) are "asbestos-free." This assumption has no basis in federal regulation.

There are three reasons why building age cannot reliably predict the presence of asbestos:

First, asbestos was never comprehensively banned in building materials. As we've established, the 1989 ban was overturned, and the 2024 ban addresses only a narrow set of products. Throughout the 1980s, 1990s, 2000s, and even into the 2010s, it remained legal to manufacture and sell building products containing asbestos in the United States. Some products simply phased out asbestos voluntarily as manufacturers found alternatives, but this was a market decision—not a legal requirement.

Second, imported building materials present a significant and often overlooked risk. A substantial portion of the building products sold in American retail stores—from drywall joint compounds to roofing materials to floor tiles—are manufactured overseas. Many of these source countries have no asbestos regulations whatsoever, or have regulations that are poorly enforced. When these products enter the U.S. market, they are not routinely tested for asbestos content. The result is that asbestos-containing materials can and do end up in new construction and renovation projects, regardless of when the building was constructed.

Third, renovation and repair work introduces materials from multiple eras. Even if the original construction of a building used no asbestos-containing materials, subsequent repairs, renovations, and additions may have introduced them. A roof replaced in 1995, a bathroom retiled in 2005, or insulation added in 2010 could all potentially contain asbestos depending on the products used.

What This Means for Property Owners

The practical implication is straightforward: testing is the only reliable way to determine whether materials in any building contain asbestos. Not the year it was built. Not the type of construction. Not the appearance of the materials. Only laboratory analysis of physical samples can confirm or rule out the presence of asbestos.

This matters in several specific situations:

Before any renovation or demolition work. Michigan's Department of Environment, Great Lakes, and Energy (EGLE) requires asbestos surveys before renovation and demolition activities under the National Emission Standards for Hazardous Air Pollutants (NESHAP). This requirement applies regardless of building age.

During real estate transactions. Buyers and sellers benefit from knowing the asbestos status of a property. Discovering asbestos-containing materials after closing can lead to unexpected remediation costs that could have been factored into negotiations.

After water damage or other property damage. When materials are disturbed by water, fire, or physical damage, any asbestos they contain can become friable—meaning the fibers can be released into the air. Restoration contractors need to know what they're dealing with before they start tearing out damaged materials.

For ongoing building maintenance. Property managers and facility managers should maintain an inventory of known or suspected asbestos-containing materials so that maintenance workers and contractors can take appropriate precautions.

The Conservative Presumption

In the environmental testing and consulting industry, we operate under what's known as the conservative presumption: when the asbestos status of a material is unknown, we presume it may contain asbestos until testing proves otherwise. This isn't excessive caution—it's the standard of care established by OSHA, EPA, and industry best practices.

This presumption exists precisely because visual identification of asbestos-containing materials is unreliable. Asbestos fibers are microscopic, and materials that contain them look identical to materials that don't. A floor tile, a piece of drywall, a section of pipe insulation—none of these can be cleared by visual inspection alone.

Protecting Yourself and Your Property

If you own, manage, or are purchasing property in Michigan, here are the key takeaways:

Do not rely on building age to determine asbestos risk. A home built in 2005 can contain asbestos-containing materials just as readily as one built in 1965.

Have materials tested before any renovation, demolition, or restoration work. This protects workers, occupants, and your liability.

Work with independent testing companies that do not also perform remediation. This eliminates the financial incentive to find—or not find—asbestos.

Maintain records of all testing results for your property. These become valuable documentation for future transactions, insurance claims, and compliance purposes.

The asbestos "ban" that most Americans believe exists is largely a myth. The regulations that do exist are narrower than most people realize, and the presence of asbestos in building materials remains a reality that property owners must actively manage through testing and informed decision-making.
