The Americans with Disabilities Act has several titles. Title II concerns state and local public entities, including local authorities and public educational institutions. The specific web and mobile-app rule supplies technical requirements for their digital content. Federal Section 508 and Title III for private entities are separate legal tracks.
A municipality using a private website or app supplier can still have duties concerning that content. Start with who provides the service to residents. Who coded the website or designed the PDF is a separate question about contracts and supplier responsibilities.
The amended dates in the table concern compliance with this technical web and app rule. They do not suspend existing duties such as effective communication and access to public programmes and services.
DOJ’s April 2026 Interim Final Rule extended the deadlines for the specific web and mobile app rule. The groups and dates appear below. The rule uses WCAG 2.1 AA.
| Group | Date |
|---|---|
| Public entities with populations of at least 50,000 under the rule’s calculation | 26 April 2027 |
| Public entities with populations below 50,000 and special district governments | 26 April 2028 |

Certain pre-existing conventional electronic documents have an exception. Documents still used to apply for, access or participate in services and programmes need a different assessment. Other ADA obligations do not disappear merely because a document is excepted from this particular rule.

The exception for preexisting conventional electronic documents can cover PDF, word-processing, presentation and spreadsheet files available on the website or app before the entity’s applicable compliance date. But the exception is limited for documents currently used to apply for, access or participate in services, programmes or activities.
Consider a historical event poster and a current application form, both uploaded years ago. The poster records a past event; the form remains an essential step for applicants. Their shared publication year does not give them identical legal treatment.
Archived web content has its own exception with several conditions, including preservation, location and absence of changes. Do not confuse it with the document exception. Certain individualised, password-protected documents also have specific treatment. Other ADA duties, including effective communication when someone needs the information, may remain applicable.

List every file in the application process. Identify which ones are necessary to apply today. Prioritise the complete task: finding instructions, understanding requirements, entering information and submitting it. Repairing only the first PDF can leave the rest of the process unusable.
Assign an owner to each component and link testing to the published version. Instructions may be on the web, eligibility conditions in a PDF and submission in an external system. Test the task through all three. One successful PDF validation report cannot establish that the complete path works.
Determine the entity’s category before using dates in the project plan. Population is not the number of website visitors, students or employees. DOJ’s guidance specifically discusses entities such as school districts. Record the basis for the chosen date so suppliers work from the same assumptions.
This guide concerns the Title II rule for state and local governments. It does not summarise Title III for private entities or federal Section 508. Also check how the entity’s population must be calculated.
