Section 504 & Section 508 services

Beyond Title II, the firm supports the two adjacent federal accessibility regimes — Section 504 for recipients of HHS financial assistance, and Section 508 for federal agencies and their contractors.

Section 504 — HHS-funded entities

Section 504 web & mobile accessibility

Recipients of HHS federal financial assistance — hospitals, federally qualified health centers, and other grantees — carry web and mobile accessibility obligations under Section 504 (45 CFR Part 84). The firm provides the WCAG 2.1 AA conformance audit, a Section 504 gap analysis, a written Compliance Plan, and a credentialed methodology attestation built for OCR response.

Section 504 deadline — extended to 2027

On May 7, 2026, HHS extended the Section 504 web and mobile deadline by one year: WCAG 2.1 AA is required by May 11, 2027 (15+ employees) and May 10, 2028 (smaller recipients). The obligation has been in force since 2024; the dates set when the technical standard applies.

Section 508 — federal agencies & contractors

Section 508 conformance & VPAT / ACR production

For federal agencies and the vendors and primes delivering to them, the firm provides Section 508 baseline conformance support and produces Voluntary Product Accessibility Templates (VPAT 2.5) and Accessibility Conformance Reports — the documentation software vendors need to clear federal procurement.

Section 508 conformance support

Baseline WCAG / 508 conformance assessment for federal civilian delivery work and contractor deliverables.

VPAT 2.5 / ACR production

Accessibility Conformance Reports for software vendors selling to the federal government, prepared under Trusted Tester methodology. $3,000–$7,500 per product, depending on scope and standards.

Subcontract testing capacity

Credentialed Trusted Tester capacity for primes that hold 508 obligations without an in-house accessibility testing practice.

Primary focus

Title II remains the core practice

The firm's primary focus is ADA Title II compliance for state and local government. Section 504 and 508 engagements are accepted where they fit the firm's credentialed methodology. See the Title II practice →
