Key takeaways
- The Justice Department says the ADA applies to goods and services businesses open to the public offer on the web, and it gives businesses flexibility in how they comply[1].
- Almost every home page has detectable problems: 95.9% of the top million home pages failed automated WCAG checks in 2026, averaging 56.1 errors each[2].
- Six issues cause 96% of detected errors, led by low-contrast text, missing image alt text and unlabeled form fields, so a small team can fix most of them in a day[2].
- More than one in four US adults has a disability, so an accessible quote form is also a conversion fix, not only a legal one[3].
Does the ADA apply to a contractor's website?
For most home service companies the practical answer is yes. In guidance published in March 2022, the Justice Department said the ADA's requirements apply to the goods, services, privileges and activities of businesses open to the public, including those offered on the web[1]. Your online quote form, booking page and service-area pages are how customers reach a service you sell, so treat them that way.
The same guidance says businesses have flexibility in how they comply, and it points to the Web Content Accessibility Guidelines (WCAG) and the federal Section 508 standards as helpful guidance rather than mandatory checklists[1]. In practice, WCAG is the yardstick that auditors, plaintiffs' firms and web developers all use, so it is the one to plan around.
This article is practical guidance, not legal advice. If you receive a demand letter or a lawsuit, talk to a lawyer before replying.
Who you lose when the site is hard to use
CDC estimates that more than one in four US adults has some type of disability. Cognitive disability affects 13.9%, mobility 12.2%, hearing 6.2% and vision 5.5%[3]. Homeowners over 65, who own many of the houses that need a new furnace or roof, are more likely to fall into one of these groups. Add the fact that 91% of US adults own a smartphone and 16% rely on it as their only internet connection[4], and a cramped, low-contrast mobile quote form is turning away paying customers whether or not anyone sues.
What automated scans find on most sites
The WebAIM Million study runs automated checks on the home pages of the top one million websites every year. In the February 2026 run, 95.9% of home pages had detected WCAG failures, with an average of 56.1 errors per page[2]. Six types made up 96% of everything detected[2]. Demand letters frequently cite exactly these failures because they are easy to find with free tools.
| Failure | How it shows up on a service company site | Fix | Effort |
|---|---|---|---|
| Low-contrast text | Light gray text on white, white text on a pale photo banner | Darken text or add a solid background behind it | Low |
| Missing alt text | Truck, team and before-and-after photos with no description | Add short, specific alt text; mark decorative images as decorative | Low |
| Unlabeled form fields | Quote forms that use placeholder text instead of labels | Add a visible label tied to each field | Low to medium |
| Empty links | Social icons and phone icons with no text | Add accessible names such as "Call us" or "Facebook page" | Low |
| Empty buttons | Menu and chat buttons that are only an icon | Give each button a text name | Low |
| Missing page language | No language set in the page code | Set the language attribute once in the site template | Very low |
A one-day accessibility fix plan
Pick the five pages that make money
Usually the home page, the main service pages, the quote or booking form, the contact page and the service-area page. Fix these first.
Run a free automated checker
Use a browser extension that flags WCAG errors. Save a screenshot or export of the results with the date; it documents where you started.
Fix contrast and alt text
These are the most common failures and the quickest to correct in most site builders.
Rebuild the quote form
Every field gets a visible label. Error messages say what went wrong in words, not only in red. Required fields are marked with text, not color alone.
Test with the keyboard only
Unplug the mouse. Can you open the menu, fill in the form and press submit using Tab and Enter? If not, ask your developer to fix focus order and visible focus outlines.
Caption your videos
Project videos and testimonials need captions. Most video platforms generate a draft you can correct in a few minutes.
Re-run the checker and save the result
Keep both reports. Repeat monthly or whenever the site changes.
Booking, phone and chat: keep more than one door open
DOJ's guidance lists barriers such as forms without proper labels or error alerts, videos without captions and mouse-only navigation[1]. You will never make every third-party widget perfect, which is why the safest pattern is to offer more than one way to book. Put a clickable phone number at the top of every page, make sure your online booking tool can be completed with a keyboard, and give a plain text alternative for anything shown only in an image, such as your service-area map or a price-range chart.
- Write the service area as a list of towns and ZIP codes, not only as a map image.
- Make the phone number real text, not part of a banner graphic.
- Check that chat widgets can be opened, used and closed with a keyboard.
- Answer the phone when people call from the site. A caller who could not use your form is already a step away from giving up.
Questions to ask your web developer or platform
Most home service companies run on a website builder, a marketing agency's template or a field service platform's booking widget. You do not need to learn code, but you do need straight answers to a few questions:
- Which WCAG version and level do you build to, and can you show me a recent scan of my site?
- Is the online booking or quote widget yours or a third party's, and has it been tested with a keyboard and a screen reader?
- Who fixes accessibility problems in the template, and are those fixes included in what I already pay you?
- When you add a new page or promotion, who checks contrast, alt text and form labels before it goes live?
- Can you give me a written list of what was fixed and when, so I have a record?
If an agency cannot answer the first question, that is useful information when the contract is up for renewal.
A short accessibility statement you can adapt
An accessibility statement tells visitors you take the issue seriously and gives them another way to reach you. Keep it short and specific. A starting point:
We want everyone to be able to book service with us. We are working to make this website meet WCAG 2.2 level AA. If any part of the site is hard to use, call us at [office phone] or email [address] and we will book your appointment by phone and fix the problem. Last reviewed: [month and year].
Put a link to the statement in the site footer. Update the review date each time you rerun your scan, and make sure whoever answers that phone number knows what the statement promises.
About overlay widgets
Some vendors sell a one-line script that adds an accessibility toolbar to your site. A toolbar can change font size or contrast for visitors who use it, but it cannot reliably write meaningful alt text for your project photos or add proper labels to a form built by another vendor. Treat any widget as an extra, not a substitute for fixing the page itself, and keep your before-and-after scan reports as the record of what you actually fixed.
If a demand letter arrives
- Do not ignore it, and do not reply without advice from a lawyer who handles ADA matters.
- Pull your saved scan reports and a list of fixes made, with dates.
- Ask your web developer or platform which pages and plugins are named, and get a written remediation plan.
- Fix the issues named in the letter first, then the rest of the five money pages.
- Add an accessibility statement with a phone number and email so visitors can report problems and get help booking.
Example: a fictional two-truck electrical contractor receives a letter citing missing alt text and an unlabeled quote form. Its developer fixes both in an afternoon, runs a new scan and adds an accessibility statement with the office phone number. The owner's lawyer handles the reply; the owner's job is the record of what was fixed and when.
Keep it fixed
Accessibility breaks quietly. A new seasonal banner with white text on a sky photo, a new promo popup or a swapped booking widget can undo last month's work. Add a quick scan to the checklist you already use before any site change, the same way you check page speed. If your company is new and the site is still being built, add accessibility to the startup legal checklist and to your service terms review so it is part of how the business runs from day one.
Frequently asked questions
Is there a federal law that says exactly which WCAG version a small business website must meet?
For private businesses, the Justice Department's 2022 guidance gives flexibility in how to comply and describes WCAG as helpful guidance. Most auditors and developers use WCAG 2.1 or 2.2 level AA as the working target.
Does a small contractor website really get ADA claims?
Claims are not limited to large retailers. Letters often cite the same automatically detectable failures, such as missing alt text and unlabeled forms, which are common on small business sites.
Will an accessibility toolbar plugin make my site compliant?
No plugin can reliably fix every underlying problem, such as meaningful image descriptions or properly labeled third-party forms. Fix the page code and keep records of what you fixed.
What is the fastest accessibility improvement for a service business?
Fix the quote or booking form: visible labels on every field, clear error messages in words and keyboard-only completion. It is where accessibility and lost leads overlap most.
