What are California's geometric door symbol requirements?
Quick Answer
California Title 24 requires 12-inch geometric symbols on restroom doors: a raised triangle for men's rooms and a raised circle for women's rooms, mounted at 60 inches to centerline. This is in ADDITION to standard ADA tactile signage.

Detailed Explanation
California has a unique requirement for geometric door symbols not found in federal ADA:
1. **Symbol Types**: - **Triangle**: Equilateral triangle, 12" per side, for men's restrooms - **Circle**: 12" diameter circle for women's restrooms - **Triangle + Circle**: Combined symbol for all-gender/unisex facilities
2. **Mounting Requirements**: - Centerline at 60" above finish floor (AFF) - On the door itself, not the adjacent wall - 1/4" minimum raised from the door surface
3. **Purpose**: Provides a tactile indicator on the door itself that can be detected by touch, supplementing the wall-mounted tactile sign.
4. **Common Oversight**: Many projects fail inspection because architects unfamiliar with California codes don't specify geometric symbols separately from tactile signage.
Common Mistakes
- ×Forgetting geometric symbols entirely (thinking ADA signs are sufficient)
- ×Mounting on the wall instead of the door
- ×Using incorrect size (smaller than 12 inches)
- ×Insufficient raised depth (less than 1/4")
- ×Wrong centerline height (not at 60")
How to Verify Compliance
- ✓Confirm 12" equilateral triangle on men's room doors
- ✓Confirm 12" circle on women's room doors
- ✓Measure centerline height at 60" AFF
- ✓Verify 1/4" raised depth with depth gauge
- ✓Check that symbols are ON the door, not adjacent wall
