Section 508 for saas & software: requirements, priorities, and audit checklist
Section 508 compliance for SaaS products requires applying Section 508 of the Rehabilitation Act to the specific failure points typical of the saas & software industry — including component libraries without semantic markup, modal dialogs that trap focus incorrectly, data tables without programmatic structure.
Does Section 508 apply to SaaS products?
Section 508 of the Rehabilitation Act requires US federal agencies, federal contractors, and recipients of federal funds to make their information and communications technology (ICT) accessible to people with disabilities, with conformance benchmarked against WCAG 2.0 Level AA via the 2017 Refresh.
SaaS & Software accessibility — the lay of the land
SaaS vendors face accessibility through two channels: their own marketing site (subject to ADA Title III), and their product (subject to procurement-driven VPAT requirements and EAA scope for consumer services). Enterprise procurement increasingly requires a current VPAT.
Where Section 508 bites hardest in SaaS products
• Component libraries without semantic markup
• Modal dialogs that trap focus incorrectly
• Data tables without programmatic structure
• Drag-and-drop without keyboard alternatives
• Status messages not announced to AT (4.1.3)
Remediation priorities
• Core admin / dashboard navigation
• Forms, validation, and error recovery
• Tables, charts, and data export
• Component library (button, input, modal, menu primitives)
• Embedded customer-facing widgets
How to comply with Section 508 on a SaaS & Software site
1. Complete a VPAT/ACR: Use the latest VPAT 2.5 template (or 2.5INT for international). Document conformance to WCAG 2.0 AA per chapter 5 of Section 508.
2. Test against WCAG 2.0 AA: Combined automated + manual + assistive-technology testing. AT-required: NVDA, JAWS, VoiceOver, ZoomText.
3. Cover all 508 surfaces: Web (chapter 5), software (chapter 4), hardware (chapter 4), and documentation/support.
4. Update annually: Federal contracts require current VPATs. Re-test after any significant product change.

Does Section 508 apply to saas & software websites?
Section 508 of the Rehabilitation Act requires US federal agencies, federal contractors, and recipients of federal funds to make their information and communications technology (ICT) accessible to people with disabilities, with conformance benchmarked against WCAG 2.0 Level AA via the 2017 Refresh.
What are the most common Section 508 failures in SaaS products?
Component libraries without semantic markup Modal dialogs that trap focus incorrectly Data tables without programmatic structure
What conformance level should a saas & software site target?
WCAG 2.2 Level AA is the consensus target for legal compliance and the level referenced by virtually every national accessibility law.
Do SaaS vendors need a VPAT?
Increasingly yes. Enterprise procurement teams — particularly in higher education, healthcare, government, and large finance — require a current VPAT/ACR before purchase. Federal vendors require Section 508 VPATs explicitly.
Is the SaaS marketing site or the product more important for accessibility?
Both are in scope under different regimes. The marketing site is ADA Title III (public accommodation). The product is procurement-VPAT-driven and increasingly EAA-driven for consumer offerings. A vendor should not treat one as adequate cover for the other.
What is the most cost-effective way for a SaaS team to start?
Three steps: (1) accessibility-instrumented component library so new screens inherit conformance; (2) axe-core in CI for regression; (3) annual manual audit against WCAG 2.2 AA with an IAAP-certified team.
