July 2, 2026 What are the Ada Requirements for Indoor Business Signs?

For indoor business signs in Canada, requirements are primarily governed by the CSA B651 accessibility standards, which align closely with the Americans with Disabilities Act (ADA) but include specific Canadian benchmarks. Key requirements for indoor signage include:

  • Tactile and Braille Features: Permanent room identification signs (such as restrooms, room numbers, and exit doors) must use Grade 2 Braille and raised characters. The braille should be placed directly below the tactile text with a dot height of 0.5 mm to 0.6 mm.
  • Visual Contrast: Signs must have a minimum 70% luminance contrast ratio between the characters and the background. Common compliant pairings include black text on a white background or white text on a black background.
  • Character Specifications: Characters must be in a sans-serif font, set in all uppercase, and feature a non-glare or matte finish to ensure readability for individuals with low vision.
  • Mounting Height: While standards vary slightly, the benchmarks are:
  • CSA B651: 1200 mm to 1500 mm measured to the center of the sign.
  • ADA: 48 inches to 60 inches measured to the baseline of the tactile characters.
  • Material Quality: Signs should be made from durable, industry-grade materials (such as UV-laminated vinyl or aluminum) that can withstand environmental conditions and high traffic.
