WCAG, ADA, EAA… WTF? Making Sense of Accessibility Laws
TL;DR: The Shortcut to Accessibility Compliance
If you’re overwhelmed by accessibility laws, here’s the simple rule:
🚀 Make sure all your digital content follows WCAG 2.1 AA, and you’re probably fine.
Why? Because most accessibility laws worldwide either reference WCAG or set standards that closely align with it.
⚠️ But don’t stop there. WCAG 2.1 AA is the minimum standard, not the gold standard. If you can do better (like implementing WCAG 2.2 or AAA guidelines) go for it! Accessibility is about creating the best experience for all users, not just checking legal boxes
Accessibility Laws Aren’t Optional Anymore
The digital world is full of acronyms… Especially when it comes to accessibility. WCAG, ADA, EAA, EN 301 549… What do they mean? More importantly, which ones actually apply to you?
How do you know what to follow? How can you be sure you’re not facing lawsuits, risking fines, or putting your clients at legal risk? Who should take responsibility to ensure a project is accessible?
This article cuts through the confusion, breaking accessibility frameworks into two clear categories:
Guidelines – Best practices that help create inclusive experiences.
Regulations – Legal requirements that can cost you if ignored.
Let’s demystify accessibility laws and help you stay on the right side of compliance (without the legal headaches).
Quick Glossary: Accessibility Acronyms You Need to Know
Before diving into laws, you can already see that accessibility is full of acronyms. Keeping track of them can be overwhelming, so here is a cheat sheet for the key terms you'll encounter in this article:
WCAG (Web Content Accessibility Guidelines): The global standard for web accessibility, created by W3C's Web Accessibility Initiative (WAI).
ATAG (Authoring Tool Accessibility Guidelines): Ensures that software (like CMS platforms) supports accessible content creation.
UAAG (User Agent Accessibility Guidelines): Defines how browsers and media players should support accessibility.
ARIA (Accessible Rich Internet Applications): A set of technical specs for improving accessibility in complex web apps.
ADA (Americans with Disabilities Act, 1990): U.S. law that courts increasingly apply to websites under Title III, requiring businesses to provide equal access to digital services.
Section 504 (Rehabilitation Act of 1973): Ensures accessibility for federally funded programs and services, covering public schools, universities, hospitals, and other entities that receive federal financial assistance.
Section 508 (Rehabilitation Act of 1973): Requires U.S. federal agencies and contractors to make electronic and IT systems (websites, software, hardware) accessible, aligning with WCAG 2.0 AA.
AODA (Accessibility for Ontarians with Disabilities Act, 2005): Canadian law requiring businesses and organizations to comply with WCAG 2.0 AA standards.
EAA (European Accessibility Act, 2019): EU-wide law mandating digital accessibility across various sectors, with full enforcement set for 2025.
EN 301 549: The European standard for ICT (Information and Communication Technology) accessibility, aligning with WCAG 2.1 AA.
UK Equality Act 2010: Anti-discrimination law that includes digital accessibility requirements, making it unlawful to exclude people with disabilities from online services.

Guidelines vs. Regulations: Rules vs. The Law
When it comes to accessibility, or really any structured system of rules, there are two key forces at play: guidelines and regulations. Understanding the difference between them is like knowing the difference between a recipe and food safety laws, or between driving best practices and traffic laws. Both are important, but they serve very different purposes.
Guidelines: The Playbook for Doing Things Right
Think of guidelines like a cookbook. A great recipe tells you how to make a dish taste amazing, it suggests the best ingredients, methods, and timing. But no one is forcing you to follow it. You might tweak it based on your preferences, resources, or skill level.
Similarly, guidelines provide best practices that help create an inclusive experience, but they are not legally required on their own. They set the gold standard for how things should be done, making them invaluable for those who want to get accessibility right rather than just meeting the bare minimum.
💡 Following guidelines means you’re aiming for excellence, not just compliance.
Regulations: The Laws You Can’t Ignore
If guidelines are like recipes, regulations are food safety laws. It doesn’t matter how delicious a meal looks, if it violates health codes, the restaurant can be shut down.
Regulations are legally binding rules set by governments or governing bodies. They must be followed, and failure to comply can lead to fines, lawsuits, and other legal consequences.
💡 Regulations exist to protect people and ensure fair access. Whether it's accessibility, food safety, or traffic laws, they provide a baseline of fairness and safety for everyone.
Where Do Technical Specifications Fit?
If guidelines are cookbooks and regulations are food safety laws, then technical specifications are the engineering blueprints for kitchen equipment. They define the precise mechanics of how something should work.
For example, a recipe might tell you to "bake at 350°F," but the technical specification tells manufacturers exactly how an oven must regulate temperature to be safe and effective.
In accessibility, technical specifications work behind the scenes to ensure tools, platforms, and technologies function properly within both guidelines and regulations.
Bringing It All Together
Guidelines help you do things well. Regulations make sure you follow the law. Technical specifications ensure everything works smoothly behind the scenes.
Now that you understand the difference, let’s break down which accessibility acronyms fall into each category, so you know exactly what to follow and why.
Making Sense of the Letters Soup…
It’s time to move past cookbooks and recipes and start categorizing all these acronyms.
Here’s the simplest way to break it down:
- WAI (Web Accessibility Initiative) is the working group that creates global accessibility guidelines. They are responsible for WCAG, ATAG, and UAAG, the key frameworks for accessibility.
- WAI is also behind the technical specification for ARIA, which helps assistive technologies interact with modern web applications.
- Then, individual countries, states, or unions establish their own regulations (ADA, Section 508, EAA, etc.) and specific technical standards (EN 301 549) to ensure compliance and prevent discrimination in digital spaces.
At the end of the day, accessibility isn’t just about avoiding fines, it’s about making digital experiences work for everyone.
OK… But Now What?
You might be asking yourself:
💭 What do I do with this information?
💭 I just follow project requirements, and if stakeholders don’t care, it’s not my problem, right?
Well, here’s the thing:
- Now that you know what’s what, you can make better decisions.
- And yes, accessibility is everyone’s responsibility.
But here’s where I challenge you: it’s even more on the development team than the stakeholders.
Let’s make a quick comparison:
Today, if a client asks for a website, there’s no debate about whether it should be responsive. It just is. Everyone expects web applications to work seamlessly across devices, whether on a desktop, laptop, phone, or tablet. If you delivered a project that broke on mobile, the client wouldn’t ask, "Why didn’t you make this responsive?". They’d assume you simply didn’t do your job right.
💡 Web Accessibility should be the same.
Clients and stakeholders shouldn’t need to request or justify it. It should just be part of how we build. If accessibility is embedded in your workflow, it won’t add significant time to your project, but it will make a huge difference for those who rely on it.
So, What Does This Mean for You?
Accessibility laws and guidelines aren’t just about avoiding lawsuits, they’re about creating better, more inclusive digital experiences. No matter your role, accessibility affects you:
- If you work in government or enterprise: Compliance isn’t optional (Section 508, EN 301 549, EAA). The EAA will be fully enforceable by 2025, meaning businesses operating in the EU must be compliant.
- If you run a business with a digital presence: ADA lawsuits are increasing, and with the EAA deadline approaching, enforcement is only getting stricter. Ensuring WCAG 2.1 AA compliance helps protect your company from legal risk while making your services more accessible.
- If you’re a designer or developer: Following WCAG and ARIA isn’t just good practice. It future-proofs your work, ensures inclusivity, and makes digital experiences better for everyone.
🚀 Next steps: Start by testing your site against WCAG 2.1 AA, prioritize accessibility fixes, and stay informed on legal updates. Accessibility isn’t just compliance, it’s good business and the right thing to do.
Final Thoughts: Accessibility is Inevitable
Whether you're just learning about accessibility or actively working toward compliance, one thing is clear: accessible design is becoming the norm, not the exception.
The question is: will you be ahead of the curve, or scrambling to catch up when the next lawsuit or regulation hits?
This article has laid the foundation, but there’s still a lot more to uncover when it comes to accessibility laws, guidelines, and best practices. Stay tuned for future articles where we’ll continue breaking down key topics to help you navigate accessibility with confidence.
