ADA compliance depends on many factors, but signage is one of the most frequently overlooked elements. An effective wayfinding system relies on clear, accessible signs to help all users navigate a space independently. When signage is missing—or improperly implemented—it can restrict access and lead to compliance issues.
Below, we’ve compiled eight common ADA signage violations, based on the 2010 ADA Standards for Accessible Design (U.S. Access Board, Chapter 7: Signs), along with guidance for avoiding them.
8 Common ADA Signage Violations
❌ 1. Missing Tactile Signs for Permanent Rooms and Spaces
Tactile signage is required for permanent rooms such as restrooms, conference rooms, libraries, and mechanical rooms. Without tactile signs, people with visual impairments cannot reliably locate spaces independently.
Common mistakes:
- No tactile signs at interior or exterior permanent rooms (§216.2)
- Missing exit stairway, floor level, or elevator labels (§216.4, §407)
❌ 2. Incorrect Installation Height or Lack of Clear Floor Space
ADA standards specify precise mounting heights for tactile signs to ensure accessibility.
Requirements:
- Raised characters and Braille: 48–60 inches from the finished floor (§703.4)
- Clear floor space: at least 18″ × 18″, free of obstructions up to 80″ high
Common mistakes:
- Signs mounted too high or low
- Floor space blocked by furniture or door swings
❌ 3. Improper Placement Beside Doors
For single doors, tactile signs should be installed on the latch side. For double doors, the sign typically goes on the inactive leaf or the right-hand leaf if both are active.
Common mistakes:
- Mounting on the hinge side
- Placing directly on glass or doors
- Incorrect placement at recessed or double-leaf doors
❌ 4. Missing Tactile Elements on Exit and Means of Egress Signs
EXIT and stairway signs often meet visual requirements but fail tactile standards.
Requirements:
- Separate tactile signs for stairways, exit passageways, and exit discharge (§216.4)
- Area of refuge signage must also be tactile (§1007.6.4 / IBC)
Common mistakes:
- Relying on a visual EXIT sign alone
- Failing to label floors or stairways with tactile content
❌ 5. Non-Compliant Raised Characters (Font, Size, or Spacing)
Raised characters must be legible and consistent.
Requirements:
- Uppercase letters, sans serif (§703.2)
- Height: ½–2 inches for tactile signs
- Stroke thickness: 10–15% of character height
- Line spacing: 135–170% of character height
Common mistakes:
- Script or decorative fonts
- Characters too tall, too short, or too close together
- Poor line spacing
❌ 6. Insufficient Contrast or Glare on Visual Characters
Visual characters must be legible, with light-on-dark or dark-on-light contrast and non-glare finishes (§703.5.1).
Common mistakes:
- Low contrast color combinations
- Glossy or reflective surfaces
- Text on textured or patterned backgrounds
❌ 7. Incorrect or Missing Grade 2 Braille
Braille must mirror the text content in Grade 2 contracted Braille (§703.3).
Common mistakes:
- Using Grade 1 Braille instead of Grade 2
- Placing Braille above or too close to raised text
- Improper dot size or spacing
❌ 8. Improper Use of Pictograms
Pictograms are optional, but when used for permanent room signage, they require text descriptors in raised characters and Braille below the field (§703.6).
Common mistakes:
- Pictograms without text descriptors
- Text placed inside the pictogram field
- Pictogram field smaller than 6″
- Ignoring contrast and finish standards
Quick Reference Table: ADA Signage Violations & Fixes
| ADA Signage Violation | Common Mistakes | How to Fix / Ensure Compliance |
|---|---|---|
| Missing Tactile Signs for Permanent Rooms | No tactile signs at restrooms, conference rooms, elevators, or stairways | Install tactile signs for all permanent rooms, exits, and elevator controls; ensure Braille is Grade 2 (§216.2, §407) |
| Incorrect Height / Lack of Clear Floor Space | Signs too high or low; obstructed floor space; within door swing | Mount tactile signs 48–60″ from floor; provide 18″x18″ clear floor space (§703.4) |
| Improper Placement Beside Doors | Signs on hinge side; on glass or doors; incorrect at double doors | Place single-door signs on latch side; double doors on inactive leaf or right-hand active leaf (§216.4) |
| Missing Tactile on EXIT / Egress Signs | Visual EXIT signs only; floor/stair labels missing | Add tactile signs for exit doors, stairways, and areas of refuge (§216.4, IBC §1007.6.4) |
| Non-Compliant Raised Characters | Script/decorative fonts; incorrect height or stroke; poor spacing | Use uppercase, sans serif; ½–2″ height; stroke 10–15%; line spacing 135–170% (§703.2) |
| Insufficient Contrast / Glare | Low contrast; glossy; textured backgrounds | Use light-on-dark or dark-on-light with non-glare finish (§703.5.1) |
| Incorrect / Missing Grade 2 Braille | Grade 1 Braille; incorrect placement; wrong dot spacing | Use Grade 2 Braille below raised text; ⅜” minimum from text/borders (§703.3) |
| Improper Use of Pictograms | No text descriptors; text inside field; field <6″; poor contrast | Provide raised text & Braille below pictogram; field ≥6″; maintain contrast & non-glare finish (§703.6) |
