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.
| If you are | The rule | Where to start |
|---|---|---|
| A US state or local government: city, county, school district, special district, state agency or public university | ADA Title II, the DOJ web rule | |
| A US federal agency, or a vendor whose documents an agency buys | Section 508, the revised 508 standards | |
| A hospital, clinic or human services provider receiving HHS funding | HHS Section 504, the HHS OCR rule | |
| An Ontario public-sector body, or an Ontario organization with 50 or more employees | AODA | |
| A business selling covered products or services in the EU | European Accessibility Act, Directive (EU) 2019/882 | |
| Any of the above | WCAG 2.1 AA and PDF/UA, the standards every rule above points at |
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
- AODA: WCAG 2.0 AA in force in Ontario
- European Accessibility Act applied across the EU
- ADA Title II: population 50,000 or more
- HHS Section 504: 15 or more employees
- ADA Title II: under 50,000, and every special district
- 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.
| Rule | Technical target | The obligation |
|---|---|---|
| ADA Title II | WCAG 2.1 AA | By April 26, 2027 or April 26, 2028, by population |
| Section 508 | WCAG 2.0 AA, by reference | In force; procurement duties |
| HHS Section 504 | WCAG 2.1 AA | By May 11, 2027 or May 10, 2028, by employee count |
| AODA | WCAG 2.0 AA | Since January 1, 2021, plus recurring compliance reports |
| European Accessibility Act | EN 301 549, which incorporates WCAG 2.1 AA | Since June 28, 2025, enforced by each member state |
| PDF/UA | ISO 14289-1 | The file-format test the laws leave unspecified |
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.
Same target, different evidence
A Title II entity has a date; an AODA organization has a recurring filing.
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.
By jurisdiction

The dates by entity size, how the population cohort is determined from Census figures, and the edge cases: special districts, public universities, county-run entities.

ADA Title II compliance deadlines by entity typeSection 508
Federal agencies' document obligations under the revised 508 standards, the WCAG 2.0 AA benchmark they incorporate, and what that means for vendors.

How the W3C's success criteria apply to PDFs, Word files, presentations and spreadsheets, criterion by criterion, and which a machine can check.
A standard, not a law: applied by every rule above
WCAG 2.1 AA applied to PDFs and documentsPDF/UA
ISO 14289: the tag tree, reading order, artifacts and metadata an accessible PDF needs, and why a validator can test it.

PDF/UA and ISO 14289 explainedAODA (Ontario)
Ontario's accessibility law and its Integrated Accessibility Standards Regulation: WCAG 2.0 AA for public web content and posted documents, the employee thresholds, the reporting cycles.
In force since January 1, 2021
AODA web accessibility requirements for documentsEuropean Accessibility Act
Directive (EU) 2019/882, the products and services it covers, the EN 301 549 standard it points at, and the documents those services deliver.
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.
Know what you publish
Start with a count of the documents your pages link to.
Scan your site freeFix what fails
Remediate to WCAG 2.1 AA and PDF/UA-1.
How bulk PDF remediation worksBe able to prove it
One verification report per file, independently validated.
What verification meansKeep 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.
