ADA sign requirements: a practical guide for building projects
The core rule is simpler than it looks: signs that identify a permanent room or space need tactile characters and braille; signs that direct or inform need to be legible, but not tactile. Everything else is details — sizes, heights and finishes.
Which signs need braille?
| Sign purpose | Tactile + braille? | Examples |
|---|---|---|
| Identifies a permanent room or space | Yes | Restrooms, room and suite numbers, stairwell IDs, electrical/janitor rooms, exit door signs |
| Directs or informs | No — visual rules only | “Units 201–212 →”, directories, “Pool hours”, amenity directionals |
| Temporary (7 days or less) or changeable | Exempt | Tenant name inserts, event notices, menus |
“Permanent” means the room’s function isn’t likely to change: a restroom is permanent; the name of the tenant inside suite 410 is not — which is why the suite number is tactile but the directory insert isn’t.
Tactile sign specifications
- Raised characters: at least 1/32" (0.8 mm) above the surface, uppercase, sans-serif, no italics or decorative fonts.
- Character height: 5/8" to 2" for tactile text.
- Braille: Grade 2 (contracted) braille with domed dots, positioned directly below the corresponding text.
- Finish and contrast: non-glare surface with high light-to-dark contrast between characters and background.
- Pictograms: where used to identify a space, the pictogram sits in its own 6"-high field with the text description below it.
Mounting height and location
- Tactile characters sit between 48" and 60" above the finished floor (measured to the baseline of the characters).
- Mount on the latch side of the door; at double doors, on the nearest adjacent wall.
- Keep an 18"×18" clear floor space centered on the sign, beyond the door swing, so a person can approach and read it by touch.
What about apartment buildings?
Common areas of multifamily buildings — lobbies, mailrooms, amenity rooms, public restrooms — are treated as public accommodations, so their identification signs follow the tactile rules above. Whether individual dwelling unit doors need tactile numbers varies by jurisdiction, funding type and applicable codes (Fair Housing Act, local building code). Many developers specify tactile unit numbers throughout for consistency and future-proofing; the per-sign cost difference in a bundle is small.
Common mistakes we see
- Braille on everything. Directional and informational signs don’t need it — it adds cost and can even confuse tactile readers looking for room IDs.
- Glossy finishes. A beautiful mirror-polish sign can fail the non-glare requirement. Use brushed or matte finishes for tactile signs.
- Wrong mounting height. Installers default to eye level (~62"); tactile signs need the 48–60" band. Every SignBundle tactile sign ships with a mounting note.
- Forgetting stairwells. Stair identification signs are among the most commonly missed — and most commonly flagged in inspection.
How SignBundle handles this
Every US building bundle starts from a template that already includes the tactile signs the building type typically needs, produced to the specifications above. During proofing we review your jurisdiction’s requirements — state amendments like California’s CBC Chapter 11B can differ from federal ADA — and confirm the final specification with you before production.
