Compliance guides

The regulatory landscape for public documents

Several overlapping rules now set deadlines for making public documents accessible, and most organizations are covered by more than one: a public hospital district answers to ADA Title II and to the HHS Section 504 rule.

These eight guides explain what each rule requires, who it covers and when, with every claim linked to its primary source.

Who it’s for

Which of these applies to you

One row per kind of organization. More than one row can be true, and usually is.

ADA Title II dates: 91 FR 20902 (April 20, 2026), amending 28 CFR 35.200(b)(opens in new tab). HHS Section 504 dates: 91 FR 25496 (May 11, 2026), amending 45 CFR 84.84(b)(opens in new tab).

The dates on the timeline

  1. AODA: WCAG 2.0 AA in force in Ontario
  2. European Accessibility Act applied across the EU
  3. ADA Title II: population 50,000 or more
  4. HHS Section 504: 15 or more employees
  5. ADA Title II: under 50,000, and every special district
  6. HHS Section 504: fewer than 15 employees

Section 508 is in force with no upcoming date; WCAG 2.1 AA and PDF/UA are standards and set none.

Rule by rule

How these rules relate to each other

Every law here names WCAG at Level AA, directly or through EN 301 549; what differs is who, when and what you must file.

Technical target and obligation, by rule
RuleTechnical targetThe obligation
ADA Title IIWCAG 2.1 AABy April 26, 2027 or April 26, 2028, by population
Section 508WCAG 2.0 AA, by referenceIn force; procurement duties
HHS Section 504WCAG 2.1 AABy May 11, 2027 or May 10, 2028, by employee count
AODAWCAG 2.0 AASince January 1, 2021, plus recurring compliance reports
European Accessibility ActEN 301 549, which incorporates WCAG 2.1 AASince June 28, 2025, enforced by each member state
PDF/UAISO 14289-1The file-format test the laws leave unspecified
  1. Where two rules apply, both apply

    WCAG 2.1 contains every 2.0 criterion, so remediating to 2.1 AA satisfies a rule written against 2.0 too.

  2. Same target, different evidence

    A Title II entity has a date; an AODA organization has a recurring filing.

  3. No law names PDF/UA

    WCAG says what accessible means; PDF/UA-1 says what it means inside a PDF, so a validator can check it.

  • European Accessibility Act

    Applied across the EU since June 28, 2025

    European Accessibility Act document requirements

Each guide cites its own regulator: the Department of Justice for ADA Title II, the Access Board and GSA for Section 508, HHS Office for Civil Rights for Section 504, the Government of Ontario for the AODA, EU member-state authorities for the EAA, and the W3C and ISO for the standards.

Standards

The two standards every rule points at

Five laws, two standards. The laws say make it accessible; the standards say what that means.

WCAG 2.1 Level AA

The W3C's success criteria, written for web content and applied by every law here to documents as well. It tells you what accessible means.

PDF/UA-1 (ISO 14289-1)

The ISO standard for accessible PDF: what accessible means inside a PDF file, from the tag tree and reading order to artifacts and metadata. A file can pass a WCAG checklist and still fail a screen reader.

Why that matters commercially. PDF/UA-1 is what an independent validator can check, which is why DocoMatic's verification validates remediated files against PDF/UA-1 with veraPDF(opens in new tab), an open-source validator anyone can run on the same file. A vendor's score is not evidence; a reproducible verdict is.

The work

What any of these actually requires you to do

The rules differ. The work does not.

  1. Know what you publish

    Start with a count of the documents your pages link to.

    Scan your site free
  2. Fix what fails

    Remediate to WCAG 2.1 AA and PDF/UA-1.

    How bulk PDF remediation works
  3. Be able to prove it

    One verification report per file, independently validated.

    What verification means
  4. Keep it from growing back

    New documents arrive weekly; monitoring catches them.

    Document monitoring

No one can certify a document as ADA compliant. There is no such certificate. What you can produce is conformance to a standard and the evidence of it; whether your obligation is met is for your counsel. The product page lists what the platform does not do.

FAQ

Frequently asked questions

General information, not legal advice: which rule applies to you, and when, is a question for your counsel.

Which accessibility law applies to my organization?

It depends on what you are. US state and local governments fall under ADA Title II; US federal agencies under Section 508; recipients of HHS funding under the HHS Section 504 rule; Ontario's public sector and larger Ontario organizations under the AODA; businesses selling covered products and services in the EU under the European Accessibility Act. More than one can apply. The table at the top of this page and the deadline finder take it a step further.

We are covered by more than one rule. Which wins?

Neither: both apply. Every law here names WCAG at Level AA, directly or through EN 301 549, so meeting the stricter technical target meets both, and remediating to WCAG 2.1 AA satisfies a rule written against 2.0. What differs is the date, the exceptions and the filings, so plan to the earliest date and keep the evidence each regime asks for.

Do these rules cover PDFs, or just web pages?

Documents explicitly. The ADA Title II rule and the HHS Section 504 rule both name documents, PDFs included, as web content that must conform. Section 508 covers the electronic documents an agency develops, procures, maintains or uses. The AODA reaches posted documents as web content, and the EAA reaches the documents a covered service delivers. Each guide sets out the exceptions.

Can a document be certified ADA compliant?

No. There is no such certificate and no body that issues one. What a document can have is conformance to a technical standard, WCAG 2.1 AA or PDF/UA-1, and evidence of it, such as a validator's report. Whether your organization's obligation is met is a legal determination for your counsel.

What is the difference between WCAG and PDF/UA?

WCAG 2.1 AA says what accessible means for any content, and it is what the laws cite. PDF/UA-1 (ISO 14289-1) says what that means inside a PDF file: a complete tag tree in reading order, artifacts for decoration, alternative text, mapped text and metadata. A PDF can tick a WCAG checklist and still fail PDF/UA, and PDF/UA is the standard an automated validator such as veraPDF tests against.

Our deadline has already passed. What now?

For the AODA and the EAA the obligation is already in force. For ADA Title II the dates are April 26, 2027 and April 26, 2028, and for the HHS Section 504 rule May 11, 2027 and May 10, 2028; the timeline above shows where today falls. Being past a date does not make enforcement automatic, and it does not excuse the obligation either. What matters is what you can show: an inventory of what you publish, remediation under way with the most-used documents first, and a verification report for every file you have fixed.

Does remediating our documents make our website compliant?

No. Documents are one part of what the rules cover. DocoMatic remediates the documents your pages link to and does not test or fix the pages themselves, so if the site needs work you need a web accessibility tool alongside it. The product page lists what the platform does not do.

Do you cover regulations outside these eight?

Not as guides. Our regulatory guidance, deadline catalog and entity registry cover the United States and Canada, plus the EAA explainer; Quebec's provincial requirements, US state-level statutes and EN 301 549 outside the EAA are not covered here. The product is not limited by that: WCAG 2.1 AA and PDF/UA are the standards those regimes reference too, so you bring your own reading of the rule and we bring the remediation and the verification report.
