Detailed Explanation
California follows the ADA 2010 Standards with additional California-specific amendments under Title 24. For tactile signs, including restroom identification signs:
1. **Height Range**: Signs must be positioned so the baseline of the lowest tactile character is at least 48 inches and no more than 60 inches above the finish floor.
2. **Latch Side Requirement**: Signs must be located on the wall adjacent to the latch side of the door. If there is no wall space on the latch side, the sign may be placed on the nearest adjacent wall.
3. **Clear Floor Space**: Viewers must be able to approach within 3 inches of the sign without encountering protruding objects or standing within the door swing.
4. **California Geometric Symbols**: In addition to tactile signs, California requires 12-inch geometric symbols (triangle for men's, circle for women's) mounted at 60 inches to centerline.
Common Mistakes
- ×Mounting signs centered at 60 inches instead of measuring to the baseline of tactile characters
- ×Placing signs on the push side of the door instead of the latch side
- ×Forgetting the 12-inch geometric symbol requirement unique to California
- ×Mounting within the door swing arc where a viewer cannot stand
How to Verify Compliance
- ✓Measure from the finish floor to the baseline of the lowest raised character
- ✓Verify the measurement falls between 48" and 60"
- ✓Confirm the sign is on the latch side of the door
- ✓Check that a person can stand and read the sign without obstruction
- ✓Verify geometric symbols are present (CA only) at 60" centerline
