The ADA Standard for Transit Facilities and Its Edition-Freeze Date
Transit facilities are governed by DOT's 49 CFR 37.9, not DOJ's ADA Standards directly — and DOT's own safe harbor freezes a different CFR edition.

What matters now
- Transit facility accessibility is defined by 49 CFR 37.9, a DOT regulation — not direct application of DOJ's ADA Standards.
- 49 CFR 37.9 cross-references 36 CFR part 1191 Appendices B and D, as modified by Appendix A to 49 CFR part 37.
- DOT adopted those appendices, with its own modifications, effective November 29, 2006.
- DOT's safe harbor lets construction begun before that date comply with the October 1, 2006 CFR edition instead.
Public transportation facilities are not governed directly by the Department of Justice’s ADA Standards. They are governed by the Department of Transportation’s own regulation, 49 CFR 37.9, which defines accessibility by cross-reference to 36 CFR part 1191 Appendices B and D, as modified by Appendix A to 49 CFR part 37 — and DOT’s regulation carries its own edition-freeze date for pre-adoption construction.
This original record-reading guide is a general reading aid, not cited evidence. It does not depict a source record; the article text and source links provide the facts.
Governing DOT regulation
The regulation that defines accessibility for transportation facilities is a DOT rule, not DOJ’s ADA Standards applied directly:
“For purposes of this part, a transportation facility shall be considered to be readily accessible to and usable by individuals with disabilities if it meets the requirements of this part and the requirements set forth in appendices B and D to 36 CFR part 1191, which apply to buildings and facilities covered by the Americans with Disabilities Act, as modified by appendix A to this part.” (49 CFR 37.9)
This is why the Access Board’s public-facing ADA Standards document treats the DOJ and DOT versions as related but separately sourced texts:
“This version of the ADA Standards combines both documents and notes unique provisions in the DOJ Standards and the DOT Standards.” (Access Board, ADA Standards)
Cross-referenced appendices
49 CFR 37.9’s cross-reference points to 36 CFR part 1191, the regulation that houses Appendices B and D (the ADA Accessibility Guidelines). That part’s own text confirms DOT adopted those appendices, with modifications, as its regulatory standard:
“The Department of Transportation has adopted by reference Appendices B and D to this part with modifications as the regulatory standards for the construction and alteration of transportation facilities subject to its regulations under the Americans with Disabilities Act, effective November 29, 2006. 49 CFR 37.9 and Appendix A to 49 CFR part 37, as amended at 71 FR 63263, October 30, 2006; and corrected at 72 FR 11089, March 12, 2007. The Department of Transportation has modified section 206.3 in Appendix B to this part; and sections 406, 810.2.2, and 810.5.3 in Appendix D to this part. The modified sections adopted by the Department of Transportation are reprinted in Appendix F to this part.” (36 CFR part 1191)
Part 1191 itself traces to a 2004 source rule:
“Source: 69 FR 44151, July 23, 2004, unless otherwise noted.” (36 CFR part 1191)
These appendices apply on a going-forward basis from that November 29, 2006 adoption date, which raises the question of what governs construction that predates it.
DOT’s freeze date
DOT’s regulation contains its own safe-harbor provision for construction that predates the November 29, 2006 adoption date. That safe harbor freezes a specific CFR edition:
“New construction or alterations of buildings or facilities on which construction has begun, or all approvals for final design have been received, before November 29, 2006, are not required to be consistent with the requirements set forth in appendices B and D to 36 CFR part 1191 and appendix A to this part, if the construction or alterations comply with the former appendix A to this part, as codified in the October 1, 2006, edition of the Code of Federal Regulations.” (49 CFR 37.9)
That frozen edition — October 1, 2006 — applies specifically to DOT’s own regulation for transit facilities. Readers researching accessibility requirements should confirm which regulator’s rule — DOT’s or DOJ’s — governs the facility type in question, since the Access Board treats the two as related but separately sourced texts (Access Board, ADA Standards).
What this article does not answer
This article settles only which regulation and which edition-freeze date govern transit facilities, based on 49 CFR 37.9 and 36 CFR part 1191. It does not assess whether any specific transit facility or station complies with the applicable standard. It does not explain what the modified sections DOT adopted — section 206.3 in Appendix B, or sections 406, 810.2.2, and 810.5.3 in Appendix D — technically require. And it does not address which agency has jurisdiction when a facility serves mixed uses. Readers with those questions should consult the full text of 49 CFR part 37, 36 CFR part 1191, and the Access Board’s published guidance directly.
