ADA Class Actions and the Rise of “Scent-Based” Accessibility Claims

If the last six months are any indication, the plaintiffs’ bar has found a new - and surprisingly pervasive -target: fragrance.

We have all experienced turning a corner and knowing what store you are about to see from the scent alone, or have been welcomed into a hotel lobby that smells the same in every city you’ve visited. But now a wave of nearly identical class action complaints are wafting their way across the country, seeking to recast this use of scented products in public buildings as a form of unlawful disability discrimination under the Americans with Disabilities Act (“ADA”), 42 U.S.C. §§ 12101 et seq.

Fragrance-based lawsuits have historically found some traction in the employment setting, but this new litigation strategy seeks recovery on a much larger scale, transforming the common branding practice of “signature scenting” into the next class-action frontier for ADA compliance risk. 

Fragrance as a Barrier to Access

The complaints we are seeing are filed across a number of industries, but focus primarily on hotel chains and retail defendants.  The core theory is the same across the board: the intentional dissemination of “synthetic fragranced consumer products” in indoor environments renders those spaces inaccessible to individuals with chemical sensitivities or related disabilities.

Plaintiffs typically allege that fragrance exposure substantially limits major life activities such as breathing or concentrating; that conditions like asthma, chemical sensitivity, and multiple chemical sensitivity qualify as ADA disabilities; and pervasive scenting policies deny disabled individuals “full and equal enjoyment” of places of public accommodation.

The complaints frame fragrance not as a benign environmental feature, but as a functional barrier akin to an architectural impediment that excludes a protected class of individuals from access.

Whoever Denied It, Supplied It

Although the claims are limited to the ADA and an (allegedly) protected class of those with fragrance sensitives, the pleadings typically also assert that these synthetic fragrances are inherently toxic to anyone that comes into contact with them, and through the use of HVAC dispersion, are inescapable. 

Plaintiffs also typically emphasize that customers are exposed without warning and cannot avoid contact before entering or traversing indoor spaces. Some individuals, the theories go, find this so offensive to their olfactory system that they alter their behavior and avoid establishments altogether, resulting in what they claim to be economic and social harms.

In short, these claims seek to recharacterize what most businesses view as ambiance into a form of compelled chemical contact.

As a result these complaints do not just seek monetary damages – as with other ADA class actions, they are seeking broad injunctive relief prohibiting the use of fragranced products in public spaces, ask for policy changes such as disclosure and removal of scent systems, and – of course – attorneys' fees and costs. 

Can We Clear the Air?

Despite the coordinated nature of these filings across multiple jurisdictions, several legal hurdles remain.

1. Defining disability and causation.
While chemical sensitivity has been recognized in some contexts, plaintiffs will still need to establish that fragrance exposure constitutes a substantial limitation on a major life activity under the ADA – which even in notoriously plaintiff-friendly California is still a big ask.

2. Reasonable modification vs. fundamental alteration.
We expect Defendants will argue that eliminating fragrance entirely, particularly where it is integral to branding, may not be a “reasonable” accommodation.

3. General applicability.
Unlike targeted barriers, fragrance exposure affects all patrons. Courts may scrutinize whether a universally applied condition can constitute discrimination absent differential treatment.

4. Where to draw the line.
If fragrance qualifies as a barrier, similar logic could extend to other environmental conditions (cleaning agents, food odors, temperature settings), raising administrability concerns.

Practical Takeaways for Businesses

Regardless of ultimate liability, the litigation trend itself presents immediate risk:

• Hospitality, retail, and residential operators are prime targets due to widespread scenting practices;
• Centralized policies and HVAC-based systems increase exposure by creating uniform, facility-wide conditions;
• Lack of disclosure appears to be a common—and easily alleged—deficiency.

Conclusion

To date, there is limited precedential guidance squarely addressing these issues, making outcomes difficult to predict. Whether courts will accept that “scent” is legally indistinguishable from a physical barrier remains to be seen. We will continue to closely monitor these claims, but for now one thing is clear: what was once a branding tool is now squarely in the crosshairs of ADA litigation. And for businesses still pumping “signature scents” through their HVAC systems, the question may no longer be what aroma aligns with your brand — but rather whether that ubiquitous scent is worth the risk.
