Detailed Explanation
EXIT sign requirements involve both accessibility (ADA) and life safety (IBC) codes:
1. **Tactile EXIT Signs (ADA)**: - Required at doors - 48" to 60" AFF (baseline of lowest character) - Located on latch side of door - Must include Grade 2 Braille
2. **Illuminated EXIT Signs (IBC)**: - Required above or adjacent to every exit door - Bottom of sign at least 80" AFF - Must be visible from the exit access corridor - 6" tall letters minimum
3. **Both May Be Required**: Many jurisdictions require BOTH a wall-mounted tactile sign AND an overhead illuminated sign at exit doors.
4. **Photoluminescent Option**: In certain jurisdictions (LA, Santa Clarita), photoluminescent or self-luminous signs may be required.
Common Mistakes
- ×Assuming overhead illuminated signs satisfy ADA requirements
- ×Mounting tactile signs above 60" AFF
- ×Forgetting latch-side placement for tactile signs
- ×Not providing both tactile and illuminated signs when required
How to Verify Compliance
- ✓Confirm tactile EXIT signs at 48"-60" AFF on latch side
