Facility Standards and Design Guidance

This page provides links to authoritative standards and best practices for physical infrastructure accessibility. These resources inform building design, construction, and renovation practices.

Note: This toolkit focuses on publishing accessibility information for building visitors. For technical design standards, construction requirements, and compliance details, refer to the resources listed below.

Design Frameworks and Principles

The 7 Principles of Universal Design

Most international accessibility standards are based on these seven principles, which serve as a foundation for inclusive design:

  1. Equitable Use: The design is useful to people with diverse abilities
    • Example: Automatic door serves all users equally
  2. Flexibility in Use: Accommodates a wide range of preferences and abilities
    • Example: Counter with multiple heights, adjustable seating
  3. Simple and Intuitive Use: Easy to understand, regardless of experience, knowledge, language, or cognitive ability
    • Example: Clear signage with text and symbols
  4. Perceptible Information: Communicates necessary information effectively to the user, regardless of ambient conditions or sensory abilities
    • Example: Tactile floor markers combined with visual signs and audio announcements
  5. Tolerance for Error: Minimizes hazards and adverse consequences of accidental or unintended actions
    • Example: Fail-safe features, warning systems
  6. Low Physical Effort: Can be used efficiently and comfortably with minimum fatigue
    • Example: Automatic doors, lever handles instead of knobs
  7. Size and Space for Approach and Use: Appropriate size and space provided for approach, reach, manipulation, and use
    • Example: Maneuvering space for wheelchair users, clear floor space at fixtures

Accessibility Assessment Resources


Relationship to Digital Accessibility

Several resources bridge physical and digital accessibility:

Wayfinding and Navigation

Physical wayfinding systems increasingly integrate with digital tools:

  • W3C Cognitive Accessibility: Wayfinding: Principles applicable to both physical signage and digital navigation tools
  • Digital wayfinding apps: Must follow WCAG 2.2 for screen reader compatibility and keyboard navigation
  • QR codes and NFC tags: When used for building navigation, the linked content must be accessible

Building Information Publishing

When publishing facility information online:

  • Website accessibility: All facility information must meet WCAG 2.2 AA
  • PDF accessibility: If offering facility guides as PDF, they must be properly tagged and screen-reader accessible
  • See: Website Placement Guidance for how to publish physical accessibility information accessibly

Machine-Readable Standards


How This Toolkit Relates to Standards

This toolkit does not:

  • Provide technical design specifications
  • Offer compliance interpretation
  • Replace architectural or code consulting

This toolkit does:

  • Help you communicate what your building offers
  • Provide templates for describing accessibility features in visitor-facing content
  • Emphasize transparency about limitations and alternatives
  • Use the Access Chain model to structure visitor information

To use these standards with this toolkit:

  1. Use facility standards when designing or renovating your building
  2. Use our templates to document what you’ve built for visitors
  3. Keep your published information accurate with governance practices
