Explore how the Americans with Disabilities Act defines what qualifies as a disability, protecting everyone's rights
The Americans with Disabilities Act (ADA) compliance is a big deal for businesses in the US, protecting a vast population. Over 70 million U.S. adults (more than 1 in 4) reported having a disability in 2022. Yet many employees choose not to disclose disabilities at work — a recent index found fewer than 5% of U.S. employees self-identified as having a disability even though 93% of their companies encouraged disclosure.
At the same time, disability-related compliance is becoming more important for employers. About 34% of all EEOC discrimination charges in 2022 involved disability claims (25,004 charges), making it the second most common claim after retaliation. ADA lawsuits have also become a major risk: federal ADA Title III cases (access to public businesses) peaked at 11,452 filings in 2021 and still numbered approximately 8,200 in 2023.
These trends show why understanding what counts as a disability under the ADA — and the law's scope of protection — is critical for business professionals, marketers, and compliance specialists.

Legally, the ADA defines "disability" as: "a physical or mental impairment that substantially limits one or more major life activities" of an individual; or having a record of such an impairment; or being regarded as having such an impairment. Each part of this definition matters:
In summary, a person qualifies as having an ADA disability if they have a significant impairment — broadly defined — that makes an aspect of daily life substantially harder for them. There is no numeric threshold or percentage impairment required. Unlike some other programs, the ADA doesn't require an impairment to be permanent or totally disabling to count. The legal emphasis is on functional limitation in context, rather than labels. Congress and the EEOC have deliberately set a low bar for "disability" so that the law protects all who need it.
The ADA provides a broad definition of "disability" to provide wider protection. Under the ADA (as amended in 2008), an individual is considered to have a disability if they meet any of these criteria:
The ADA Amendments Act of 2008 (ADAAA) directed that this definition be interpreted in favor of broad coverage. Congress expanded coverage because many people with serious conditions (like epilepsy, diabetes, multiple sclerosis, or depression) were being denied ADA protection under earlier, narrow court rulings. The ADAAA "reinstated a broad scope of protection," rejecting prior strict interpretations and making it much easier for individuals to demonstrate a disability.
Another key point is that impairments that are episodic or in remission can still be ADA disabilities. The law specifies that an impairment that is episodic (or in remission) qualifies if it would substantially limit a major life activity when active. For example, conditions like epilepsy, asthma, hypertension, or cancer in remission are covered because during active phases they limit major life activities.
All in all, ADA's coverage is not limited to visible, constant disabilities — it covers many intermittent or managed health conditions as well.
The ADA has been in effect for over three decades, yet it continues to expand its influence in American workplaces and public spaces. What qualifies as an ADA disability is intentionally broad, covering a vast range of physical and mental impairments. For businesses, the data and trends are clear: ADA compliance is not optional or static — it's an active, ongoing effort.

For marketers and compliance teams specifically, the increasing focus on digital accessibility presents both challenges and some opportunities. With over 4,500 ADA-related website and app accessibility lawsuits filed in 2023 alone, making sure your marketing materials are accessible might not be mandatory but it’s an essential risk management.
Marketing assets that fail to comply with accessibility standards can expose your organization to legal liability, damage your brand reputation, and exclude potential customers. Every email campaign, social media post, website update, and marketing collateral should be designed with accessibility in mind. This includes proper alt text for images, adequate color contrast, captioned videos, properly structured content for screen readers, and avoiding time-dependent responses.
