Title III of the Americans with Disabilities Act covers places of public accommodation, and US courts have repeatedly treated the websites of such businesses as within scope. Website accessibility lawsuits have been filed in the thousands annually, and the pattern is consistent: they target small and medium businesses, they are usually settled rather than fought, and veterinary practices are not exempt by size.
We are not lawyers and this is not legal advice. What follows is the practical engineering side.
The legal position, briefly
There is no single federal regulation that spells out a technical standard for private business websites. In practice, courts and settlements have converged on WCAG 2.1 Level AA as the benchmark. If a site meets that, the argument largely goes away.
The usual trigger is not a disgruntled client. It is an automated scan run at scale against many sites, followed by a demand letter. Which means the way to not receive one is to not fail the automated checks — and those checks test a fairly short list.
Who it actually affects
Set the lawsuits aside for a moment. The people a failing veterinary site excludes are:
- Clients over seventy, who are over-represented among pet owners with long-term patients, and who are the group most affected by low-contrast text and small tap targets.
- Anyone using a screen reader, for whom an unlabelled phone-number image or a form field with no label is a dead end.
- Anyone on a phone in daylight, which is most people — contrast failures that are invisible on your monitor are disqualifying outdoors.
- Anyone who cannot use a mouse, including people with tremor, arthritis or a temporary injury, who need the site to work from a keyboard.
Every accessibility fix on this list also makes the site easier for a worried person holding a cat in one arm.
Ten fixes that cover most of it
- Colour contrast of at least 4.5:1 for body text and 3:1 for large text. The commonest veterinary failure by a distance is pale grey text on white, and light grey on a brand colour.
- Alt text on every meaningful image, and empty alt on decorative ones. A photo of the team needs a description; a background texture does not.
- Your phone number as text, not inside an image or a graphic header. This fails accessibility, SEO and AI retrieval all at once.
- Labels on every form field. Placeholder text is not a label — it disappears the moment someone types.
- A visible focus ring. Many themes remove it for looks. Tab through your own site: if you cannot see where you are, neither can a keyboard user.
- Headings in order. One h1, then h2s, then h3s. Screen reader users navigate by heading, and a page that jumps from h1 to h4 is a page they cannot skim.
- Tap targets of at least 44×44 pixels. Particularly the phone number and the booking button.
- Captions on video. If you have a practice tour video, it needs them.
- No information conveyed by colour alone. A red dot meaning “closed” needs the word next to it.
- A visible skip link so keyboard users can jump past the navigation to the content.
Why overlay widgets are not the answer
The accessibility overlay industry sells a line of JavaScript that promises compliance in a day. Accessibility practitioners and disability advocacy groups have been broadly critical of them, and a substantial number of the lawsuits filed in recent years have been against sites that had an overlay installed.
The reasoning is straightforward: an overlay cannot write alt text for your photos or fix your contrast ratios, because it does not know what your images show or what your brand colours are meant to be. It can add a toolbar. The toolbar is not what is being tested.
Spend the money on fixing the ten things above instead.
Testing it yourself in an hour
- Run Lighthouse in Chrome's developer tools. The accessibility section will catch contrast, missing alt text, unlabelled fields and heading order in about thirty seconds.
- Tab through the whole site. No mouse. Can you reach the phone number, open the menu, fill the form and submit it? Can you always see where you are?
- Zoom to 200%. Does anything overlap or disappear? This catches a lot of theme failures.
- Turn the screen to greyscale. Is anything now ambiguous? That finds colour-only signals.
Lighthouse will not catch everything — roughly a third of WCAG criteria require a human — but a site that passes all four of those is not the low-hanging fruit an automated demand-letter scan is looking for.
Try it here: click the page below, then press Tab a few times. On a phone, use the Next button. Each press is one step for someone who cannot use a mouse.
Care for every pet in the family.
Getting it right at build time
Building to WCAG AA from the start adds a modest amount to a project. Retro-fitting it afterwards costs several times more, because contrast failures are usually brand-colour decisions and changing them late means revisiting everything.
If you are commissioning a new site, make “WCAG 2.1 AA, verified with an automated and a manual pass” an explicit line in the brief, and ask to see the Lighthouse report before you sign it off. That one sentence is covered further in how to hire a veterinary website designer.
Questions we get asked
Do veterinary websites have to be ADA compliant?
US courts have repeatedly treated the websites of places of public accommodation as within the scope of Title III of the ADA, and veterinary practices are not exempt by size. There is no single federal technical standard for private business sites, but courts and settlements have converged on WCAG 2.1 Level AA as the benchmark. This is a summary, not legal advice.
What is the most common accessibility failure on veterinary websites?
Insufficient colour contrast — pale grey body text on white, or light text over a brand colour. It is also the easiest to fix and the first thing an automated scan reports.
Do accessibility overlay widgets make a site compliant?
Accessibility practitioners and disability advocacy groups have been broadly critical of them, and many accessibility lawsuits have been filed against sites that had an overlay installed. An overlay cannot write alt text or choose accessible brand colours, which is where most failures actually are.
How can I test my veterinary website's accessibility for free?
Run Lighthouse in Chrome's developer tools, then tab through the entire site without a mouse, zoom to 200% to check nothing overlaps, and switch the display to greyscale to find anything signalled by colour alone. That covers most of what automated scans look for.
Is it cheaper to build accessibly or fix it later?
Considerably cheaper to build it in. Retro-fitting usually means revisiting brand colour decisions and every page that used them, which is why remediation typically costs several times what designing to the standard would have.
