ADA 2027 Deadline: Large Government Entities
April 26, 2027 is the ADA Title II web accessibility compliance deadline for state and local government entities serving populations of 50,000 or more. If your entity is in this category, you have until that date to bring all web content and mobile apps into conformance with WCAG 2.1 Level AA.
Your window is open — but remediation takes time
Typical remediation timelines for government sites run three to twelve months depending on the size and complexity of the site. Large entities that wait until 2027 to begin will find the work harder and more expensive than those who start now. A baseline scan today gives you a prioritized list of issues and a timestamped record that you began assessing your compliance — which matters if a complaint is ever filed.
The first step is knowing where you stand. A free scan gives you a baseline WCAG 2.1 AA score and a list of the violations you need to fix.

Which entities have the 2027 deadline?
The April 26, 2027 deadline applies to state and local government entities serving populations of 50,000 or more:
Large entities (population 50,000 or more)
State and local government bodies whose jurisdiction or service area serves a population of 50,000 or more people. Population is measured by the total population of the jurisdiction, not by website visitors or service recipients. If your entity falls in this category, April 26, 2027 is your compliance date.
Examples of covered entities:
Small entities (under 50,000) and all special district governments have until April 26, 2028.
What does WCAG 2.1 Level AA require?
The DOJ's final rule (28 CFR Part 35) specifies WCAG 2.1 Level AA (June 2018 version) as the technical standard. It applies to all web content and mobile apps used to deliver government services, programs, or activities to the public.
WCAG 2.1 AA includes 50 success criteria organized under four principles: content must be Perceivable (text alternatives for non-text content, captions for video, sufficient color contrast), Operable (keyboard accessible, no seizure triggers, sufficient time limits), Understandable (readable, predictable, error identification), and Robust (compatible with assistive technologies like screen readers and braille displays).
Limited exceptions
The rule includes narrow exceptions: archived web content not updated after the compliance date and stored solely for reference; content posted by uncontrolled third parties; and pre-existing conventional documents (PDFs, Word docs) not currently used to access government services. Content used to deliver public services or programs must comply regardless of format.
What is exempt from the rule?
Archived content
Web content not updated after the compliance date and stored solely for reference or historical purposes.
Uncontrolled third-party content
Content posted by third parties — comments, user-generated content — that the entity does not control and does not pay for.
Pre-existing conventional documents
PDFs and Word documents that are not currently used to access government services or programs. Documents used to deliver services must still comply.
Exclusively internal content
Content used exclusively for official governmental functions that is not available to the public. If it is used to deliver services to constituents, it must comply.
These exceptions are narrow. If content is used by constituents to access government services or programs, it must comply. Consult legal counsel to evaluate specific content.
What enforcement looks like after April 2027
DOJ enforcement actions
After April 26, 2027, the Department of Justice can investigate and bring enforcement actions against non-compliant large entities. The DOJ can initiate investigations proactively — it does not need to wait for a complaint to begin an investigation.
Private lawsuits under Title II
Individuals can file private lawsuits under ADA Title II once an entity is in violation. Plaintiff law firms actively monitor government websites following compliance deadlines. Filing activity historically increases sharply after a deadline passes.
Federal funding implications
Non-compliance with ADA Title II can affect federal funding eligibility. Entities receiving federal financial assistance also have separate obligations under Section 504 of the Rehabilitation Act, which carries additional enforcement mechanisms through funding agencies.
HHS complaint process
Individuals can also file complaints with the Department of Health and Human Services Office for Civil Rights. HHS has authority to investigate compliance and, in cases of non-compliance, can initiate proceedings to terminate federal financial assistance.
How to get compliant before the 2027 deadline
Government sites that complete remediation well before April 2027 have time to test, verify, and document their compliance — the three things that matter most if a complaint is ever filed.
Run a baseline accessibility scan
Start with an automated WCAG 2.1 AA scan of your key public-facing pages. This gives you an objective score, a prioritized list of violations, and a timestamped record that you began assessing compliance — which matters in any future enforcement context.
Identify your highest-risk pages
Prioritize the pages constituents use to access services: online payment portals, permit applications, service request forms, contact pages, and any pages linked from official government notices. These are the most likely targets of complaints.
Fix critical and serious issues first
Focus on violations that completely block access: missing alt text on important images, keyboard traps, unlabeled form fields, and color contrast failures. These are the most common complaint triggers and typically the fastest to remediate.
Test with assistive technology
Automated tools identify many common failures but cannot catch everything. Supplement with manual testing using screen readers (NVDA, VoiceOver, JAWS), keyboard-only navigation, and browser zoom at 200% minimum.
Publish an accessibility statement
Document your conformance level, any known limitations, your remediation timeline, and a contact point for users reporting barriers. An accessibility statement demonstrates good-faith effort and can reduce complaint escalations.
Set up ongoing monitoring
New content, redesigns, and third-party integrations regularly introduce accessibility regressions. Automated monthly monitoring keeps you from slipping back below compliance as your site evolves.

Under the DOJ's final rule (28 CFR Part 35, published April 24, 2024) as amended by a DOJ Interim Final Rule (effective April 20, 2026), these entities must have all web content and mobile apps conforming to WCAG 2.1 Level AA by that date. Small entities (under 50,000 population) and all special district governments have until April 26, 2028.
Which government entities have the April 2027 deadline?
The April 26, 2027 deadline covers state and local government entities that serve populations of 50,000 or more. This includes large city and county governments, state agency websites and portals, public universities serving large populations, large public school districts, state court systems, DMV portals, large public transit agencies, and large public library systems. Population is measured by the total population of the jurisdiction, not by website traffic.
What does WCAG 2.1 Level AA require?
WCAG 2.1 Level AA is the technical standard specified in the DOJ's rule (June 2018 version). It requires web content to be Perceivable (text alternatives for images, captions for video, sufficient color contrast), Operable (keyboard navigable, no seizure triggers, enough time to interact), Understandable (readable text, predictable behavior, error identification), and Robust (compatible with assistive technologies like screen readers). There are 50 success criteria at Level AA. An automated scanner can identify many common failures; manual testing with assistive technology is recommended for full verification.
What happens if my government entity misses the 2027 deadline?
After April 26, 2027, non-compliant large entities become subject to DOJ enforcement actions and private lawsuits under ADA Title II. The DOJ can initiate investigations proactively without waiting for a complaint. Individuals can file complaints with the DOJ or HHS. Plaintiff law firms actively monitor government websites following compliance deadlines. ADA web accessibility settlements frequently involve mandatory remediation requirements, monitoring periods, and significant legal costs.
Are public school districts covered by the 2027 deadline?
Public school districts are state or local government entities subject to ADA Title II. Large districts serving populations of 50,000 or more fall under the April 26, 2027 deadline. Smaller districts (under 50,000 population) have until April 26, 2028. Coverage includes district websites, student information portals, online registration forms, and any web-based applications used to deliver district programs and services.
Does the 2027 deadline apply to state government agencies?
Yes. State agencies are state government entities covered by ADA Title II. Most state agencies serve populations well above 50,000 and fall under the April 26, 2027 deadline. This covers agency websites, online service portals, digital forms, and any web-based application used to deliver state programs or services to the public.
