The hidden costs of partial WCAG compliance and why isn’t Level AA always enough?
You hired someone to get you to Level AA WCAG compliance. You might tell yourself that’s good enough, but going halfway or stopping at “Level AA” can cost you in ways you don’t expect.
This article uncovers those hidden costs and explains why aiming for full WCAG compliance makes sense. We will also guide you on what to do next, especially if you are at the decision stage.

What is Partial WCAG Compliance?
You might assume that following conformance to WCAG means the whole site is accessible. However, technically, it might mean something much less.
- WCAG defines three levels of conformance: Level A is basic, Level AA is mid-level, and Level AAA is the most stringent.
- A statement of partial conformance is when a website indicates: “We don’t fully conform, but would conform if some bits we don’t control were removed.”
- For example, a website might use a third-party plugin or widget that doesn’t meet the criteria. The site owner may mark those parts as uncontrolled and claim partial compliance.
So, is “partial compliance” good enough in practical terms? Partial levels of conformance explicitly mean that there are known accessibility gaps somewhere.
Someone with a disability might hit those gaps and be blocked. That can translate into legal risk, lost audience, and poor reputation, among other issues.

What Are the Hidden Costs of Stopping at Partial (or Just Level AA) Compliance?
You might think you are covered at Level AA WCAG accessibility. However, the hidden costs of doing less than full compliance are substantial. Here are the big ones:
Litigation Risk
If you claim compliance and are missing key pieces in an interactive feature, you expose yourself to legal actions.
For example, one industry brief noted that accessibility lawsuits averaged $4,000 in 2019 but jumped to $39,000 in 2022 for certain web accessibility claims.
It’s a clear gap when a user cannot complete a checkout or critical flow because of accessibility barriers. There will inevitably be a cost associated with that.
Reputation
You may claim to care about accessibility, but partial compliance creates barriers, and word gets out. This can lead to losing customers or earning a public accessibility complaint.
A site that is harder for someone to use will likely see a drop in SEO rankings and conversions.
Missed Audience
You miss out on real traffic and real customers when you are not fully serving the disabled audience.
Furthermore, accessibility best practices often align with broader UX improvements. Overlooking WCAG guidelines regarding keyboard navigation, clear headings, and alt text can cause you to miss significant growth opportunities.
Remediation Costs
You accumulate technical debt by launching new features that are not engineered with accessibility in mind. Reports show that remediation costs rise dramatically if accessibility is tacked on late in the development process.
Every new module or widget adds risk and cost, so it is crucial to integrate accessibility from the start.
Maintenance Burden
Understand that accessibility is an ongoing effort. Content updates, new features, and third-party embeds can all introduce new issues.
Businesses must continually exert effort and incur expenses to maintain accessibility.
If you only stop at AA and do not monitor continuously, old issues will resurface and create unplanned costs.
Compliance Gaps
Your main website pages might meet Level AA, yet your PDFs, videos, dynamic content, or dashboards do not. This means parts of your offering are unusable to some users.
This is a major hidden cost: You may drive traffic but lose conversions because a critical document couldn’t be used.

Why Isn’t Level AA Enough?
Level AA is the standard, but it might not be enough in your specific case. Here are some reasons:
| Level AA is Not Enough | The Shortcomings |
|---|---|
| Not suitable for unique risk profile | Complex apps, dashboards, or tools may need AAA |
| Partial compliance means gap exposure | Declaring “partial conformance” still leaves users blocked |
| Accessibility is better for everyone | Better UX, navigation clarity, and device usability helps all users |
| Future-proofing | WCAG updates over time; stopping at AA today means expensive rework |
| Contracts may demand more | Government and enterprise sectors often expect higher conformance |
Q: Why isn’t Level AA compliance enough for most websites?
A: Because complex websites need higher standards. Stopping at Level AA can leave gaps, cause extra fixes later, and may not meet legal or contract requirements.

What Should You Do? A Practical Game Plan for WCAG Accessibility
Here is a clear plan for moving from AA-only compliance to a robust WCAG posture.
Step 1: Conduct a Full Audit. Go Beyond Automated WCAG Testing
Do not rely solely on free automated tools. Utilize a combination of manual testing and auditing documents, as well as third-party widgets.
According to W3C, if a process has many pages and just one fails, the entire process fails under WCAG.
Book a consultation now to audit your web assets and identify full-scope gaps.
Step 2: Prioritize the Gaps
Categorize issues based on the audit results. Group them as:
- Critical barriers: Issues that completely stop users.
- Major issues: Problems that significantly hurt the user experience.
- Minor issues: Cosmetic problems that still matter.
Prioritize remediation and plan for documents, media, dynamic features, and third-party content.
Step 3: Go Beyond the Minimum Where It Makes Sense
Level AA is often considered a minimum target. Go further based on your specific business scenario.
Do not treat accessibility only as a cost center; it should be viewed as an investment.
For example, high-stakes documents, multimedia, and app-based interactions should aim for selective Level AAA criteria. This approach can position your brand from merely “meets basic compliance” to being “accessible for all.”
Step 4: Communicate Your WCAG Certification
Communicate your accessibility achievements after remediation. Make it a part of your brand story.
You will be amazed at the outcomes, as there will be fewer user complaints, fewer legal complaints, and improved SEO.

Conclusion
If you run a website and stop at partial compliance without a full strategy, you are exposing your business to hidden costs.
Level AA is a good start, but it cannot fully protect your business from legal risk and extra maintenance. In many real-world scenarios, partial WCAG compliance simply isn’t enough on its own.

FAQs
1. What is WCAG Level A, AA and AAA compliance?
Level A covers the most basic accessibility requirements. Level AA takes things a step further and is the standard most laws refer to. Level AAA is the highest level for enhanced accessibility in reading or website navigation.
2. Is WCAG Level AA compliance enough to keep my website out of legal trouble?
Level AA is the usual target for most organizations. However, if your website has complex features, apps, or third-party tools, basic AA compliance may still leave you exposed to serial litigants.
3. What happens if my website is only partially WCAG compliant?
Partial compliance means some parts of your site still create barriers for disabled users. This can result in user complaints and lawsuits if those barriers prevent access to important actions.
4. Is it cheaper to make my site WCAG compliant now or wait until later?
Fixing it later almost always costs more. A full audit and remediation may seem costly at first, but it is cheaper than regular fixes and potential legal fees. Prevent accessibility issues from the start to save costs down the road.
5. How do I tell if my website conforms to WCAG standards?
Automated tools are a good place to start, but they often miss what real people experience. A professional audit provides accurate results by combining automated checks with manual testing. Schedule a 30-minute WCAG compliance consultation to get an action plan.
