Website accessibility for US service businesses: what the ADA asks for
The direct answer
The Americans with Disabilities Act applies to state and local governments under Title II and to businesses open to the public under Title III, and the Department of Justice has consistently taken the position that both cover what those organisations offer on the web. For a business open to the public, the requirement is full and equal enjoyment of its goods and services, which includes providing appropriate communication aids where they are needed. The Department has no detailed regulation setting out technical standards for those businesses, so the method of compliance stays open, while the requirement itself does not. Its guidance names the failures it sees most often: poor colour contrast, colour used as the only signal, images without a text alternative, videos without captions, forms without labels and error messages, and pages that only work with a mouse.
Five conclusions
The argument, compressed.
- Title III covers businesses open to the public, and the Department of Justice reads it as reaching what they offer on the web.
- The requirement is full and equal enjoyment of goods and services, including appropriate communication aids.
- There is no detailed federal technical standard for public accommodations, so the method of compliance is open.
- The guidance names specific failures: contrast, colour as the only signal, missing alt text, missing captions, unlabelled forms and mouse only navigation.
- Headings, keyboard access and a way to report a problem are the cheapest improvements available to most small sites.

The accessibility pass
Five checks that cover most of what a small service business website gets wrong.
Decision 01 / 05
Start with the text
Read the page as a screen reader would: one heading per section, in order, with link text that says where the link goes.
Which organisations the ADA covers
Title II covers state and local governments, and the Department of Justice reads it as applying to all of their services, programs and activities, including the ones offered on the web. Title III covers businesses open to the public, sometimes called public accommodations, and the same reasoning applies: the Department has taken the position since 1996 that the ADA reaches what those businesses make available online.
The examples the guidance gives are ordinary commercial settings, including retail stores, banks, hotels, hospitals and medical offices, and food and drink establishments. A service business with an enquiry form, a booking page and a client portal is in that group.
What is actually required
For a business open to the public, the standard is full and equal enjoyment of the goods, services, facilities, privileges, advantages or accommodations it offers. Where a communication aid is needed for effective communication, the business has to provide an appropriate one, and the guidance lists interpreters, note takers, captions and assistive listening devices as examples.
The important nuance is that the Department has no detailed regulation setting technical standards for public accommodations. Businesses have flexibility in how they comply, and the requirement itself does not move. That combination is why the practical approach is to follow a recognised standard voluntarily rather than to look for a safe harbour.
The barriers the guidance names
The guidance lists failures rather than standards, which makes it a useful checklist for a small site. Poor colour contrast stops a reader with limited vision from reading the text at all. Using colour as the only signal fails anyone who cannot distinguish it, and screen readers never announce colour. Images without a text alternative leave the content of the image unreachable. Videos without captions exclude a deaf visitor. Forms without labels, instructions and visible errors cannot be completed. Navigation that assumes a mouse locks out anyone using a keyboard.
- Text that fails contrast against its background.
- Information carried by colour alone.
- Images with no text alternative.
- Video with no captions.
- Forms with no labels, instructions or error messages.
- Journeys that only work with a mouse.
Which standards to borrow
Because the Department sets no technical standard for businesses, the useful move is to adopt one that already exists and is checkable. The guidance points to the Web Content Accessibility Guidelines published by the World Wide Web Consortium, and to the Section 508 standards the federal government uses for its own sites.
It also offers a caution about tooling. Automated checkers are helpful, and a clean report does not mean everything is accessible, just as a short list of errors does not by itself mean a visitor is blocked. Pairing an automated check with a manual pass, keyboard included, is what produces a defensible result.
Making it a habit rather than a project
Most small sites treat accessibility as a repair. Treated as a build rule, it changes the work itself: headings become structural rather than visual, images get written descriptions as they are chosen, captions are part of the video brief, and forms are labelled before they are styled.
The guidance also suggests publishing a way for a visitor to report a problem. That single line converts an argument about compliance into a queue of fixes, and it tells a visitor that the site was built with them in mind.
The keyboard test
Put the mouse aside and complete the main journey with the keyboard alone, from the homepage to a submitted enquiry. Whatever blocks it is the first thing to fix.
Before you use it
Questions that can change the recommendation.
Does the ADA apply to a business website?
The Department of Justice has consistently taken the position that it does. Title III covers businesses open to the public, and the requirement is full and equal enjoyment of the goods and services offered, including online.
Is there a fixed technical standard for business websites?
The Department has no detailed regulation setting technical standards for public accommodations. Businesses have flexibility in how they comply, and the requirement to provide accessible service does not move, so most borrow the Web Content Accessibility Guidelines.
What failures does the guidance name?
Poor colour contrast, colour used as the only signal, images without a text alternative, videos without captions, forms without labels and error messages, and navigation that assumes a mouse.
Do accessibility overlays solve the problem?
The guidance treats automated checkers and overlays as helpful tools that need care. A clean report does not establish accessibility by itself, and pairing an automated check with a manual review is the reliable route.
