# Denton County Texas Government Website Accessibility: Denton, Lewisville, Carrollton, and the April 2027 DOJ Title II Deadline

Denton County sits in the northwestern corner of the DFW Metroplex, stretching from Carrollton and Lewisville in the south to Denton in the north and continuing to the Texas-Oklahoma border. With approximately 920,000 residents, Denton County is one of the larger suburban counties in the United States — and one that has seen dramatic population growth since 2000.

The DOJ Title II Final Rule requires every covered state and local government entity to bring its public-facing web content and mobile applications into conformance with WCAG 2.1 Level AA. In Denton County, five government entities clearly exceed the 50,000-person threshold: the county itself, the cities of Denton, Lewisville, Carrollton, and Lewisville ISD. Two public universities — UNT and TWU — and Denton ISD are below the threshold and face the 2028 deadline instead.

Here is the entity-by-entity breakdown.

The Deadlines

The DOJ Title II Final Rule — extended by interim final rule on April 20, 2026 — sets two compliance dates:

Who Is Covered and When

Denton County government — approximately 920,000 residents. dentoncounty.gov, the county courts, the county clerk's property records portal, the tax assessor-collector, the elections administrator, and county department sites are all covered. Deadline: April 26, 2027.

City of Denton — approximately 147,000 residents, county seat and the largest city in Denton County. cityofdenton.com and associated department portals — online utility services (Denton Municipal Electric is a city-owned utility), permitting, city council meeting records, library system, parks and recreation. Deadline: April 26, 2027.

City of Lewisville — approximately 116,000 residents. cityoflewisville.com and associated department portals. Deadline: April 26, 2027.

City of Carrollton — approximately 141,000 residents. Carrollton is split between Denton County and Dallas County. cityofcarrollton.com and associated portals are covered regardless of which county the municipal boundary falls in — the city is the covered entity. Deadline: April 26, 2027.

Lewisville Independent School District — approximately 55,000 students. Above the 50,000 threshold. lisd.net, parent portal, enrollment systems, board meeting records, and the district's PDF library. LISD serves communities across Denton County and parts of Dallas County. Deadline: April 26, 2027.

Denton Independent School District — approximately 35,000 students. Below the 50,000 threshold. Denton ISD faces the same WCAG 2.1 Level AA standard with one additional year. Deadline: April 26, 2028.

University of North Texas (UNT) — approximately 44,000 students. A public research university in the UNT System. Below the 50,000 threshold. UNT is a state government entity independently covered by Title II. unt.edu, student portals, course registration systems, library systems, and departmental sites are all covered. Deadline: April 26, 2028.

Texas Woman's University (TWU) — approximately 16,000 students. A public university in the Texas Woman's University System, primarily serving a female student population and offering graduate health science programs. Below the 50,000 threshold. twu.edu and associated portals are covered. Deadline: April 26, 2028.

Denton County Transportation Authority (DCTA) — DCTA operates the A-train commuter rail connecting Denton to the DART rail system in Carrollton, as well as bus service across Denton County. DCTA is independently covered as a public transit authority under the DOJ Title II Final Rule. dcta.net, trip planner, schedule PDFs, real-time arrival information, and paratransit booking (Access) are all covered. DCTA serves a population well above 50,000. Deadline: April 26, 2027.

The Deadline Split: Understanding the Threshold

The two-deadline structure is not a binary. It applies entity by entity. Denton County government (April 2027) and Denton ISD (April 2028) may share a geographic footprint, but they have different compliance deadlines because the threshold analysis is conducted separately for each government entity.

This matters for planning. An IT director at the City of Denton managing the city's compliance program cannot assume that UNT's compliance status — or lack thereof — affects the city's obligations. Each entity's compliance program stands alone.

UNT and TWU should not treat the April 2028 deadline as an indication that accessibility compliance is less urgent. The standard is identical: WCAG 2.1 Level AA. The timeline is one year later.

What WCAG 2.1 Level AA Requires

WCAG 2.1 Level AA has 50 success criteria across four principles:

Perceivable:

Operable:

Understandable:

Robust:

The rule covers PDFs, online forms, videos, maps, and third-party platforms. The City of Denton's Denton Municipal Electric billing portal, LISD's third-party parent communication app, UNT's learning management system, DCTA's trip planner — all covered.

High-Risk Compliance Areas in Denton County

Denton Municipal Electric (DME) online portal. The City of Denton operates its own municipal electric utility. The online account management portal — bill payment, usage monitoring, outage reporting — is a high-volume, high-stakes accessible form requirement. Utility payment portals are among the most common accessible-form failure sites in local government.

DCTA A-train and bus digital services. Transit trip planners and paratransit booking systems carry the highest accessibility stakes. The A-train connects Denton to DART's rail network — riders who depend on transit disproportionately include people with disabilities. DCTA's trip planner must work with keyboard navigation and with NVDA and VoiceOver screen readers. The paratransit booking system (Access) must be auditable and correctable by users with visual impairments.

Lewisville ISD parent portal and document library. LISD's parent-facing portal and enrollment system are high-volume service access points for families across one of Denton County's more diverse school districts. Third-party platforms used by the district (Skyward, ParentSquare, or equivalent) are covered by the district's compliance obligation even if they are not hosted on district infrastructure.

UNT and TWU student-facing digital services. Both universities maintain extensive student portals — course registration, financial aid, transcript requests, library access, accessible course material repositories. Graduate programs at TWU include health sciences — its student portal serves a population that includes clinicians with disabilities in training programs. Accessibility failures in financial aid or enrollment systems at a public university create direct access barriers to higher education.

Government meeting video archives. Denton County, the City of Denton, and Lewisville ISD all maintain video archives of public meetings. Auto-generated captions do not meet the accuracy and synchronization standard required for compliant captions under WCAG 1.2.2. Manual caption verification is the requirement.

PDF libraries across all entities. Budget documents, development plans, staff reports, court records, board policies, and university handbooks — all potentially in PDF format, many as scanned images. Scanned-image PDFs fail WCAG entirely. Even text-layer PDFs frequently lack correct heading structure, reading order, and alternative text for embedded graphics.

The Texas Context

Texas DIR provides statewide technology accessibility guidance for state agencies aligned to Section 508. The DOJ Title II Final Rule governs state and local government accessibility independently. Each Denton County entity — the county, each city, each ISD, DCTA, UNT, TWU — is independently responsible for its own compliance program. County compliance does not satisfy the cities. LISD compliance does not satisfy Denton ISD.

The DFW Metroplex as a whole has dozens of independently covered government entities. Denton County entities may benefit from coordination with adjacent counties (Dallas County, Collin County, Tarrant County) that are navigating the same timeline and compliance requirements, but each compliance program is legally separate.

A Realistic 11-Month Compliance Timeline

For Denton County entities facing the April 26, 2027 deadline:

May–July 2026: Scope definition. Inventory all covered domains, applications, PDF libraries, and video content. Identify the internal compliance owner — typically the IT director or ADA coordinator. Issue or award a professional WCAG audit engagement.

August–September 2026: Professional WCAG audit. Manual testing with NVDA on Windows and VoiceOver on macOS and iOS. axe-core automated scan across all identified pages. PDF sampling from document libraries. Video captioning accuracy review. Findings documented against WCAG 2.1 Level AA success criteria with severity classifications.

October 2026: Findings report delivered. Remediation plan developed with responsible parties, severity tiers, and completion dates.

October–February 2027: Remediation. Critical failures — keyboard traps, inaccessible authentication, unlabeled transactional forms — within 60 days. Major failures — contrast, PDF remediation, video captioning — through December 2026. Moderate findings through January 2027.

February 2027: Re-audit of remediated findings.

March 2027: DOJ-compliant accessibility statement published on all covered domains.

April 26, 2027: Compliance deadline for Denton County, Denton, Lewisville, Carrollton, Lewisville ISD, and DCTA.

For Denton ISD, UNT, and TWU facing the April 26, 2028 deadline: the same sequence begins 12 months later.
