What Is Section 508 Compliance and Does It Apply to My Website?
Section 508 is part of the Rehabilitation Act of 1973, amended in 1998 to address electronic and information technology. It requires federal agencies to make their digital content accessible to people with disabilities — employees and members of the public alike. If a website is built, maintained, or funded by a federal agency, Section 508 applies directly.
Here’s where private businesses often get confused: Section 508, on its own, does not apply to your company’s website. It targets government entities. But that narrow definition misleads a lot of site owners into thinking they have no legal exposure at all. They do — just under a different law.
The ADA (Americans with Disabilities Act) is what typically governs private businesses, and in March 2024 the DOJ published a final rule formally requiring state and local governments — and, by extension, businesses open to the public — to meet WCAG 2.1 Level AA standards. So while you may not be subject to Section 508 directly, the practical accessibility requirements that apply to your website are nearly identical. The two frameworks share the same technical backbone.

Where the Confusion Comes From?
I talk to business owners almost every week who have received a demand letter or discovered an accessibility lawsuit and immediately search “Section 508 compliance” because that’s the phrase they heard. The reality is that most private-sector websites are subject to ADA website compliance rules, not Section 508 — but the confusion is understandable because the technical standards overlap significantly.
Both frameworks point to WCAG guidelines as the benchmark. Section 508 was refreshed in 2018 to align with WCAG 2.0 Level AA. The DOJ’s 2024 ADA web rule requires WCAG 2.1 Level AA. If your site meets WCAG 2.1 Level AA — which is the standard we work toward at Acute ADA Compliance — you are essentially satisfying both frameworks at once.
One thing worth calling out: contractors and vendors who do business with the federal government can fall under Section 508 indirectly. If a federal agency purchases software or services from your company, you may need to produce a Voluntary Product Accessibility Template (VPAT) demonstrating your product’s accessibility. In that case, Section 508 is very much your concern.

What WCAG 2.1 Level AA Actually Requires?
The Web Content Accessibility Guidelines are published by the W3C and organized around four principles: content must be perceivable, operable, understandable, and robust. Level AA is the middle tier — it goes further than the minimum (Level A) without demanding the stricter Level AAA requirements that most commercial sites would struggle to meet.
In practice, meeting WCAG 2.1 Level AA means your site needs proper keyboard navigation so users who cannot use a mouse can still access every page. It means sufficient color contrast — the ratio for normal text is at least 4.5:1 against its background. It means images carry meaningful alt text, videos include captions, and interactive elements use ARIA labels so screen readers can interpret them correctly. Forms need clear labels and descriptive error messages. Pages need logical heading structures. None of this is cosmetic; it directly affects whether real users can access your content.
From my experience doing accessibility audits on hundreds of websites, the most common failures are color contrast issues, missing ARIA labels on icons and buttons, and broken keyboard navigation on custom dropdown menus or modal windows. These are also among the first things plaintiffs’ attorneys look for when building a case.

Overlays Do Not Solve the Problem
This comes up constantly. Accessibility overlay products promise to bring your site into compliance by adding a script to your page. Most are marketed aggressively and priced to look like an easy fix. They are not.
I’ve written in more detail about the overlay problem, but the short version: overlays work on top of inaccessible code without fixing the underlying issues. Screen reader users — the people these tools claim to serve — frequently report that overlays make their experience worse, not better. The DOJ’s web guidance does not endorse overlays as a compliance method. Several companies that relied on overlays have still faced successful lawsuits.
Real compliance requires actual code remediation — fixing the HTML, ARIA structure, focus order, and visual design at the source.

How to Know Where Your Site Actually Stands?
The first step is an honest assessment. Automated scanners catch roughly 30–40% of accessibility issues — they are useful for quick triage but not for making a compliance determination. A thorough accessibility audit combines automated testing with manual review, including screen reader testing and keyboard-only navigation checks.
If you’re unsure how the process works from discovery through remediation, our how-it-works page walks through it step by step. And if you run a law firm, there are specific considerations around client portals, intake forms, and document downloads that go beyond a standard site review — you can read more about that here.
What we usually recommend for businesses that have received no prior accessibility guidance is to start with a professional audit before spending anything on fixes. You need to know the actual scope before estimating remediation cost or prioritizing what gets addressed first.

The Real Risk of Doing Nothing in 2026
Web accessibility lawsuits have risen steadily for six consecutive years. The 2024 DOJ final rule removed the ambiguity that some businesses used as cover — courts no longer have to infer that the ADA applies to websites, because the regulation now says it explicitly. Being a small business is not a reliable defense. Plaintiffs’ firms specifically target smaller companies because they are less likely to have legal teams on retainer and more likely to settle quickly.
Our team has worked with businesses across industries that thought their site was “probably fine” and discovered significant gaps only after receiving a demand letter. Getting ahead of it is almost always cheaper than responding to litigation.
You can see what our clients have to say about the audit and remediation process — the feedback we hear most often is that people wish they had addressed it sooner.

Whether Section 508 applies to your site directly or not, the technical bar you need to clear is the same: WCAG 2.1 Level AA. The question is whether you get there proactively or reactively.
If you want a straight answer about where your website stands, schedule a consultation with Acute ADA Compliance and we will give you a clear picture — no guesswork, no pressure, just an honest assessment of what needs to be done.
