Which Code Applies in My State?
The governing code depends on your state's adoption status and local amendments. Generally:
- California: CA Title 24 typically governs as it's usually stricter
- Other states: Check your state's building code adoption and any local amendments
- Federal facilities: Federal ADA (federal ADA) always applies regardless of location
When CA Title 24 Applies

- Any project seeking California building permit
When Federal ADA Applies
- All 50 states for public accommodations

Key Differences
- •California requires 12" geometric symbols on restroom doors (triangle/circle) - ADA does not
- •California Braille spacing is stricter (0.1" exact) than federal tolerances
- •California AB 1732 mandates all-gender signage for single-user restrooms
- •Certain California cities require photoluminescent signs in buildings over 75 feet
- •California has more specific requirements for sign placement clearances
For Architects & Specifiers
- When specifying for California projects, always reference CBC 11B, not just ADA
- Include geometric symbols in specifications for California restroom doors
- Specify California-compliant Braille spacing explicitly in submittals
- Check local city amendments (LA, SF, Oakland, Santa Clarita) for additional requirements
- Signs manufactured to California specs will comply with ADA, but not vice versa
