In the sign industry, ADA signage refers to signs designed, fabricated, and installed to comply with the Americans with Disabilities Act Accessibility Guidelines. The 2010 ADA Standards for Accessible Design divides these into three categories: tactile signs for permanent rooms and exits, visual-only signs for directions, and overhead signs. It does not apply to temporary signs used for seven days or less.
Common Fabrication Methods
Manufacturers build tactile ADA signs using several methods to create the required raised characters and Braille.
- Applique and raster: Raised acrylic characters are routed or laser-cut and chemically bonded to a base material. Grade 2 Braille is created by pressing acrylic or metal beads into drilled holes.
- Photopolymer: Light-sensitive resin is exposed to ultraviolet film. This creates a solid face with built-in tactile text and Braille.
- Etched and cast: Zinc, magnesium, bronze, or aluminum is chemically etched or cast for high-abuse environments or exterior use.
- UV-cured tactile print: Ultraviolet ink is built up in multiple layers directly onto the sign material.
Code Requirements and Local Variations
The 2010 ADA Standards apply across the United States. Federal rules require a non-glare finish, high dark-to-light contrast, Grade 2 Braille, and uppercase sans-serif text raised at least 1/32 inch. Character height must be between 5/8 inch and 2 inches.
Local jurisdictions often adopt specific variations, so sign companies check local building codes during the sign permit process. For example, California Title 24 requires distinctive geometric symbols directly on restroom doors in addition to wall signs. Title 24 also mandates stricter spacing for Braille dots.
What Affects the Cost of ADA Signage
Prices for these signs depend on several manufacturing choices. Estimators often use sign estimating software to track these variables.
- Substrate material: Base materials range from standard acrylic to metal or solid surface materials.
- Fabrication method: Techniques like photopolymer tooling have different production costs than raster bead insertion.
- Design elements: Custom color matching and changeable insert windows for modular office names add production time.
- Mounting hardware: Standard tape and silicone mounting costs less than vandal-resistant hardware.
Sign codes change and vary by zoning district and overlay. Confirm with the authority having jurisdiction before submitting a permit.
Frequently Asked Questions
Does every sign in a building need Braille?
No. Only signs identifying permanent rooms, spaces, and safety exits require tactile text and Braille. Directional and informational signs require specific sizing and visual contrast, but they do not need Braille. Temporary signs and company logos are exempt.
Can we use our corporate brand fonts and colors?
You can use brand colors and fonts only if they meet specific ADA rules. The text must be sans-serif, uppercase, and non-condensed. The sign must also have a matte or non-glare finish and high visual contrast between the background and the text.
Where must tactile room signs be mounted?
Tactile character baselines must sit between 48 inches and 60 inches above the finished floor. The sign must be centered on an 18-inch clear floor space on the latch side of the door. Overhead signs require at least 80 inches of clearance.
How do sign companies quote ADA signage on site?
Estimators use sign company software like Vuely. A rep visits a customer's site, captures a survey with photos and measurements, and Vuely generates a photo-accurate mockup of the sign on the customer's actual building, checks the design against the local city sign code, estimates price, and collects a signature before the rep leaves.
Vuely is AI sales software for sign companies: site surveys, mockups on the customer's own building, and sign code checks before the quote goes out.
