ADA Website Accessibility for US Small Businesses
Why ADA website accessibility matters for US small businesses, what WCAG 2.1 and 2.2 AA require, and a practical plan to find and fix barriers on your site.
US small businesses that serve the public should make their websites accessible to people with disabilities, because the Department of Justice has stated that the Americans with Disabilities Act applies to websites and courts have heard many website accessibility cases. The practical standard to aim for is WCAG 2.1 or 2.2 Level AA, which covers things like readable contrast, alt text, keyboard navigation and properly labeled forms.
This article explains the landscape in plain terms and gives you a working plan. It is general information, not legal advice; if you receive a demand letter, speak to an attorney.
Key takeaways
- Title III of the ADA covers businesses open to the public, and the DOJ has said that includes their websites.
- There is no detailed federal technical rule for private business websites yet, so WCAG 2.1 or 2.2 Level AA is the widely used benchmark.
- Automated scanners catch only part of the problem; manual testing with a keyboard and a screen reader is essential.
- Accessibility overlays and widgets do not make a site compliant on their own.
- Building accessibility in from the start costs far less than retrofitting a finished site.
What the law says, in brief
The ADA was passed in 1990, before most businesses had websites, so it does not mention them explicitly. Title III prohibits disability discrimination by "public accommodations," a category that includes retailers, restaurants, medical offices, hotels, gyms and many other businesses. In 2022 the Department of Justice published guidance stating that businesses open to the public must make their online offerings accessible.
In 2024 the DOJ issued a rule under Title II requiring state and local governments to meet WCAG 2.1 Level AA on their websites and mobile apps, with compliance deadlines phasing in by entity size. That rule does not apply directly to private businesses, but it signals which standard regulators regard as reasonable.
Private lawsuits and demand letters are the main enforcement pressure for small businesses. Some states have their own accessibility laws as well, and Colorado has strengthened protections for people with disabilities in recent years. Your attorney can tell you how those apply to you.
What WCAG actually asks for
The Web Content Accessibility Guidelines are published by the World Wide Web Consortium and organized around four principles: content must be perceivable, operable, understandable and robust. Level AA is the middle of three levels and the one most policies reference. WCAG 2.2, published in 2023, adds criteria on top of 2.1, such as minimum target sizes and avoiding redundant data entry.
For a typical small-business site, these are the requirements that come up most:
| Area | What good looks like |
|---|---|
| Images | Meaningful images have descriptive alt text; decorative images are marked to be ignored. |
| Color contrast | Normal text has at least a 4.5:1 contrast ratio against its background; large text at least 3:1. |
| Keyboard access | Every link, button, menu and form works with the keyboard alone, with a visible focus indicator. |
| Forms | Each field has a visible label, errors are described in text and required fields are clearly indicated. |
| Headings and structure | One H1 per page and a logical heading order so screen reader users can navigate. |
| Video and audio | Captions for video with speech; transcripts for audio content. |
| Links | Link text describes the destination; avoid a page full of "click here." |
| Zoom and reflow | Content remains usable when zoomed to 200 percent and on narrow screens without horizontal scrolling. |
A practical accessibility plan
Step 1: Run an automated scan
Free tools such as WAVE or the accessibility audit in Chrome's Lighthouse flag missing alt text, low contrast, empty links and form fields without labels. They are fast and useful, but they detect only a portion of the issues WCAG covers.
Step 2: Test with a keyboard
Put your mouse away and press Tab through your homepage, a service page and your contact form. Can you see where you are at every step? Can you open the menu, close a pop-up and submit the form? If you get stuck, so will keyboard and switch-device users.
Step 3: Try a screen reader
VoiceOver is built into Macs and iPhones, and NVDA is free for Windows. Listen to how your page is announced. Unlabeled buttons read as "button," and images without alt text are skipped or read as file names.
Step 4: Fix by priority
Start with anything that blocks a task entirely, such as a booking form that cannot be completed or a checkout that traps keyboard focus. Then address contrast, alt text and headings site-wide through your templates, so one fix covers many pages.
Step 5: Publish an accessibility statement
Describe the standard you are working toward, known limitations and how people can reach you for help, including a phone number and email. It shows good faith and gives visitors a path when something does not work.
Step 6: Keep it accessible
Accessibility erodes as content changes. Train whoever updates the site to write alt text, use headings properly and caption videos, and include periodic checks in your maintenance routine.
About accessibility overlays
Overlays are scripts that add a toolbar or claim to fix accessibility automatically. They can be tempting because they are cheap and quick. However, they generally cannot repair underlying code problems such as unlabeled forms or keyboard traps, and many disability advocates criticize them. Businesses using overlays have still been sued. If you use one, treat it as an extra, never a substitute for fixing the site. The Federal Trade Commission has also taken action against an overlay vendor over its compliance marketing claims.
What accessibility costs
The cost depends on the size and age of your site. On a new build, accessible design is mostly a matter of discipline: choosing compliant colors, writing semantic code and testing as you go. That is why Kemafy designs every site with accessibility in mind from the first wireframe, whether it is an affordable small-business site or a larger custom platform. On an older site built with a heavy theme, remediation can take longer than a rebuild. Our maintenance plans can include periodic accessibility checks, and our Denver web design team can review your current site and tell you honestly whether to fix or rebuild.

Frequently asked questions
Does the ADA apply to my small business website?
If your business is open to the public, the DOJ's position is that your website should be accessible under Title III. Size alone does not exempt you. Consult an attorney about your specific situation.
Which WCAG version should I follow?
Aim for WCAG 2.1 Level AA at a minimum. Meeting WCAG 2.2 Level AA is a stronger position, since it includes all 2.1 criteria plus newer ones.
Will an accessibility plugin make my site compliant?
No plugin or overlay can guarantee compliance. Accessibility depends on how the site is designed, coded and written, which requires manual review and fixes.
How much does it cost to make a website accessible?
It varies with the site's size, age and platform. Building accessibility into a new site adds relatively little, while remediating an older site can be substantial, so request an audit first.
What should I do if I receive an ADA demand letter?
Do not ignore it. Contact an attorney experienced in ADA matters, and ask a qualified developer to audit your site so you understand the actual issues.
