# Government Website ADA Compliance 2027: The Complete Guide to the April Deadline

If you run IT for a state or local government agency and someone has mentioned "the 2027 ADA website compliance deadline," this post tells you exactly what it is, what it requires, whether it applies to your agency, and what a compliance program looks like in practice.

What Changed and Why

Title II of the ADA has prohibited disability discrimination in government programs and services since 1990. That prohibition always applied to government websites — courts have generally interpreted it to require that online services not discriminate against people with disabilities. But until March 2024, there was no specific technical standard.

In March 2024, the Department of Justice published a Final Rule under Title II that established a specific standard: government websites and mobile apps must conform to WCAG 2.1 Level AA. This is the same accessibility standard used by the federal government under Section 508, by the European Union under EN 301 549, and by most major enterprise web accessibility programs.

The rule closes the "what does accessible actually mean?" question. The answer is now legally defined: WCAG 2.1 Level AA.

Who Must Comply and When

April 26, 2027: State and local governments with a total population of 50,000 or more.

April 26, 2028: State and local governments with a total population under 50,000.

The deadline applies to:

"Total population" refers to the population of the entity's jurisdiction, not the population of the website's users or the size of the agency's staff.

An important clarification: The rule requires compliance — not just a plan for compliance — by the deadline. An agency with an audit and a remediation plan in progress but significant non-compliance remaining on April 26, 2027 is not compliant. The deadline is the compliance date, not the start-of-work date.

What WCAG 2.1 Level AA Requires

WCAG 2.1 Level AA has 50 success criteria organized under four principles:

Perceivable. Content must be presentable to users in ways they can perceive. The most commonly failed criteria:

Operable. All functionality must be operable by users who cannot use a mouse. The most commonly failed criteria:

Understandable. Content and interfaces must be understandable. The most commonly failed criteria:

Robust. Content must be compatible with current and future assistive technology. The most commonly failed criteria:

What Is Covered

The rule covers all web content and mobile apps that a public entity:

This includes:

Limited exceptions exist for truly archived content, pre-existing documents no longer actively used, and content posted by third parties not under contract to the agency.

What Is Not Covered

The rule does not apply to:

The Enforcement Mechanism

DOJ enforcement of Title II web accessibility follows a complaints-first model. A resident with a disability files a complaint with the DOJ, DOJ investigates, and agencies that cannot demonstrate compliance face corrective action.

Corrective action under Title II typically includes:

Agencies that have documented their compliance program — audit, remediation plan, progress tracking — are in a substantially different negotiating position than agencies that have ignored the requirement.

Private lawsuits under Title II of the ADA are also possible, though less common for government web accessibility than DOJ-initiated enforcement.

What a Compliance Program Looks Like

Four components make a defensible government website ADA compliance program:

1. A WCAG 2.1 Level AA audit. A professional assessment using both automated tools and manual testing with assistive technology (NVDA, VoiceOver) across a representative sample of the site and document library. Automated tools alone detect only 57% of failures and do not produce defensible compliance documentation.

2. A remediation plan. A documented timeline with responsible parties and target completion dates for each finding, organized by severity. Critical failures first, then major, then minor. Built to reach compliance by the deadline with margin for re-testing.

3. An accessibility statement. Published on the website, identifying the standard (WCAG 2.1 Level AA), the auditor, known limitations, and a contact mechanism for residents who encounter barriers.

4. Sustainable production processes. New content, new forms, new documents must meet the standard going forward. An accessibility fix overridden by the next content update is not a compliance program.

Starting Now

From today (May 2026) to the April 2027 deadline is approximately 11 months. A realistic plan:

An agency starting procurement in Q3 or Q4 2026 is building a timeline that cannot realistically reach compliance by the deadline.

The Parallax WCAG audit from Morton Technology Consulting is designed for exactly this timeline — built for Florida government agencies, 200 representative pages, NVDA and VoiceOver manual testing, full findings report, remediation roadmap, accessibility statement. The sample audit report is at morton-digital.com/parallax-sample-audit.

If you need to establish a self-assessment baseline before engaging an auditor, the free WCAG 2.1 AA Checklist and the WCAG Pre-Audit Readiness Kit ($149) provide the tools to understand your current state before writing the RFP.
