28 CFR Part 35 · Appendices A–E
The Appendices: DOJ's Own Guidance
Last updated June 11, 2026
The regulation itself is only half the story. Five appendices to 28 CFR Part 35 contain the Department of Justice's official interpretive guidance — the reasoning behind the rules. Here's what each one covers and when you'd reach for it.
- Appendix A Guidance to revisions of the 2010 rule
DOJ's section-by-section analysis of the 2010 amendments — the closest thing to an official explanation of what each provision means and why it was written that way. Courts cite it regularly.
- Appendix B Guidance on the original 1991 regulation
The Department's preamble guidance to the original Title II rule. Still relevant for provisions that haven't changed since 1991.
- Appendix C Guidance on the definition of disability
Explains the 2016 amendments implementing the ADA Amendments Act: how 'disability' must be construed broadly, and what that means for coverage decisions under §35.108.
- Appendix D Guidance on the web and mobile accessibility rule
DOJ's analysis of Subpart H: how the WCAG 2.1 AA requirement works, how the exceptions apply, and how compliance will be assessed. Essential reading alongside §§ 35.200–35.205.
- Appendix E Guidance on accessible medical diagnostic equipment
DOJ's analysis of Subpart I: scoping percentages, the exam table and weight scale requirements, and qualified staff duties under §§ 35.210–35.213.
