Code Compliance Q&A
Expert answers to common questions about ADA signage, California Title 24, and IBC 2026 building code requirements. Each answer is verified against current standards.
Installation & Mounting
Answers about proper sign placement, mounting heights, and installation requirements.
What is the required mounting height for restroom signs in California?
In California, ADA tactile signs must be mounted with the baseline of the lowest tactile character at 48 inches minimum and 60 inches maximum above the finish floor (AFF), measured to the centerline of the sign.
What does "latch side" mean for ADA sign mounting?
The latch side is the side of the door where the door handle/latch mechanism is located. ADA signs must be mounted on the wall adjacent to the latch side so users can read the sign while the door is open.
Where do ADA signs go on double doors?
For double doors, mount the tactile sign on the wall to the right of the right-hand door (when facing the doors from outside). If no wall space exists, signs may be mounted on the nearest adjacent wall or projecting from above.
What mounting methods are acceptable for ADA signs?
Common ADA sign mounting methods include VHB (Very High Bond) double-sided tape, mechanical screws with decorative caps, silicone adhesive, and standoffs. All methods are acceptable as long as the sign is securely mounted at the proper height.
Braille Requirements
Guidance on Grade 2 braille requirements and specifications.
What is Grade 2 Braille and why is it required on ADA signs?
Grade 2 Braille is a contracted form of Braille that uses abbreviations and contractions for common letter combinations. ADA requires Grade 2 Braille on all tactile signs because it is the standard literacy form used by Braille readers.
Where should Braille be positioned on an ADA sign?
Braille must be positioned directly below the corresponding tactile text, with a minimum 3/8 inch (9.5mm) clear space between the bottom of the tactile characters and the top of the Braille cells.
California-Specific Requirements
California Title 24 and CBC-specific requirements.
What are California's Braille spacing requirements?
California Title 24 requires stricter Braille spacing than federal ADA: exactly 1/10 inch (0.1") for dot spacing within cells. This is a California-specific amendment that causes many out-of-state signs to fail inspection.
What are California's geometric door symbol requirements?
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.
What are California's all-gender restroom signage requirements?
California AB 1732 requires all single-user toilet facilities to be designated as all-gender, with signage identifying the room as "All-Gender," "Gender Neutral," or similar inclusive language, plus the International Symbol of Accessibility if accessible.
What is a CASp inspection in California?
CASp (Certified Access Specialist Program) is a California certification for accessibility experts who can inspect and certify that buildings meet ADA and Title 24 requirements. A CASp inspection provides legal protection by showing good faith compliance efforts.
Life Safety Signs
Exit signs, fire safety, and emergency signage requirements.
When are photoluminescent exit signs required?
Photoluminescent exit signs are required in Los Angeles high-rise buildings (over 75 feet) per LAMC 91.1028.4, Santa Clarita commercial buildings over 3,000 sq ft, and in specific high-rise/high-hazard occupancies per IBC 1013 and NFPA 101.
What is the required mounting height for EXIT signs?
ADA tactile EXIT signs at doors must be mounted 48"-60" AFF (baseline of lowest character). Overhead illuminated EXIT signs must have the bottom of the sign at least 80" AFF per IBC. Both types may be required at the same door.
What information is required on stairwell identification signs?
IBC requires stairwell signs at each floor landing showing: floor level (4" tactile numbers), stair designation, roof access indication, and re-entry floor information. Signs must be mounted on the wall side of the landing.
Are fire extinguisher identification signs required?
NFPA 10 requires fire extinguishers to be identified with signs when not readily visible from normal viewing angles. Signs must be placed above or near the extinguisher location with lettering at least 1 inch tall.
What signage is required in stairwells?
Stairwells require tactile floor identification signs at each floor landing, positioned 60" AFF on the latch side of the door. California also requires roof access identification and emergency egress information on these signs.
When are fire extinguisher signs required?
Fire extinguisher location signs are required when the extinguisher is not immediately visible from normal approach paths, when stored in cabinets, or when required by the Authority Having Jurisdiction. Signs must include the universal fire extinguisher symbol.
General Questions
Common questions about ADA signage compliance.
What are the main differences between federal ADA and California Title 24?
California Title 24 generally includes stricter requirements than federal ADA, including tighter Braille spacing (1/10"), 12-inch geometric door symbols, and specific photoluminescent sign requirements in certain cities. When both codes apply, use the stricter standard.
Are room number signs required to have Braille?
Yes. All permanent room identification signs, including room numbers, must have tactile characters and Grade 2 Braille per ADA 703. This applies to offices, conference rooms, and any space with a permanent designation.
Do directional and wayfinding signs need Braille?
No. Directional and wayfinding signs that provide guidance but do not identify a specific room or space are exempt from tactile/Braille requirements. However, they must still meet visual requirements including minimum character size and contrast.
Should signs say "RESTROOM" or "BATHROOM"?
Both "RESTROOM" and "BATHROOM" are acceptable for ADA compliance. However, "RESTROOM" is more commonly used in commercial settings. California building inspectors generally accept either term as long as the sign meets tactile and Braille requirements.
When are ADA signs required for buildings?
ADA signs are required for all places of public accommodation (ADA Title III) and state/local government facilities (ADA Title II), including new construction, alterations, and existing facilities where barriers can be removed without undue burden.
What happens if my signs fail ADA inspection?
Failed signage inspection requires correction before certificate of occupancy is issued. Common outcomes include re-inspection fees, project delays, and the cost of replacement signs. SpecCodes offers a pass guarantee to avoid these issues.
Can ADA signs be in multiple languages?
Yes. ADA signs can include multiple languages, but only one language (typically English) needs to meet tactile and Braille requirements. Additional languages can be visual-only but must not interfere with the compliant primary text.
What signage is required for changing rooms and fitting rooms?
Changing rooms and fitting rooms require ADA-compliant room identification signs with tactile text and Braille, mounted 48-60" AFF on the latch side. Accessible fitting rooms must include the ISA symbol and be identified as accessible.
Materials & Specifications
Technical details about materials, dimensions, and durability standards.
What are the ADA requirements for tactile character height?
ADA tactile characters must be 5/8 inch (16mm) minimum and 2 inches (51mm) maximum in height, with a stroke width to height ratio between 1:5 and 1:10, and raised at least 1/32 inch (0.8mm) from the sign surface.
What are the contrast requirements for ADA signs?
ADA requires a light-on-dark or dark-on-light contrast between characters and background, with a minimum 70% contrast ratio recommended. Signs must have a non-glare finish to prevent reflections that reduce readability.
What is the required contrast ratio for ADA signs?
ADA requires a minimum 70% contrast ratio between characters and background on tactile signs. This is measured using light reflectance values (LRV) and applies to both raised characters and the sign background.
What materials are acceptable for ADA signs?
ADA does not mandate specific materials, but signs must be durable, non-glare, and allow for raised characters of 1/32" minimum. Common materials include acrylic, photopolymer, thermoformed plastic, wood, and metal with applied tactile elements.
How long do ADA signs last?
Quality ADA signs with properly applied tactile elements typically last 10-20 years for interior applications. Factors affecting lifespan include material quality, UV exposure, cleaning methods, and environmental conditions.
Symbols & Pictograms
Information about pictograms, ISA symbols, and visual elements.
What signage is required for accessible restrooms?
Accessible restrooms require the International Symbol of Accessibility (ISA) on the sign, plus tactile text stating the room type ("RESTROOM," "MEN," "WOMEN," etc.) and Grade 2 Braille. The ISA must comply with specific proportions per ADA 703.7.2.1.
What signage is required for elevators?
Elevators require floor designations with tactile characters and Braille on both door jambs, car controls with tactile/Braille floor identifications, and the ISA symbol at accessible elevator entrances. California adds specific requirements for emergency telephone signage.
What are the requirements for accessible parking signs?
Accessible parking spaces require vertical signs with the ISA symbol, "VAN ACCESSIBLE" designation for van spaces, minimum $250 penalty notice (California), and must be mounted 60" minimum to the bottom of the sign. Ground markings alone are insufficient.
What are the requirements for pictograms on ADA signs?
Pictograms on ADA signs must be in a 6-inch minimum height field, have a text descriptor below the pictogram field (not within it), and meet contrast requirements. Common pictograms include the ISA symbol, gendered figures, and information symbols.
When is the International Symbol of Accessibility (ISA) required?
The ISA wheelchair symbol is required on signs for accessible parking spaces, accessible entrances (when not all entrances are accessible), accessible restrooms, and accessible routes. It must be used as specified without modification.
