ADA signs — the tactile, Braille-equipped signage required by the Americans with Disabilities Act — are a legal requirement for most Denver businesses, not an optional upgrade. Whether you’re opening a new commercial space, renovating an existing one, or responding to a compliance inspection, understanding what ADA signage requires is the first step to getting it right.
This guide covers the core ADA signage requirements that apply to Denver businesses, the types of signs that must comply, key specifications for mounting and installation, and what to look for when choosing a sign company to handle your project.
What Are ADA Signs, and Why Do They Matter for Denver Businesses?
The Americans with Disabilities Act, passed in 1990 and updated through the 2010 ADA Standards for Accessible Design, requires that commercial and public-access facilities provide signage that can be read by individuals with visual impairments. This includes signs that use raised tactile letters, Grade 2 Braille, non-glare finishes, and specific color contrast ratios.
ADA signage requirements apply to any business that qualifies as a “place of public accommodation” under federal law — which covers most commercial properties in Denver, from retail stores and office buildings to medical facilities, restaurants, hotels, and multi-tenant complexes. In Colorado, state building codes align closely with federal ADA standards, meaning Denver businesses generally follow a single, consistent set of requirements.
Non-compliance carries real consequences. The Department of Justice can investigate ADA complaints, and businesses found in violation face fines starting at $75,000 for a first offense and up to $150,000 for subsequent violations. More commonly, non-compliant businesses face civil lawsuits from individuals with disabilities — a category of litigation that has increased steadily in Colorado over the past decade.
Which Signs in Your Denver Business Must Be ADA Compliant?
Not every sign in your building requires ADA compliance — the requirement applies specifically to signs that identify permanent rooms and spaces, and to signs that direct people to accessible features. Here’s a breakdown of what applies to most Denver commercial properties:
Permanent Room and Space Identification Signs
Any sign that permanently identifies a room or space — conference rooms, restrooms, offices, storage areas, stairwells, utility rooms, exits — must include raised tactile characters and Grade 2 Braille. These are the signs that are most commonly cited in compliance inspections and the most frequently needed after a renovation or tenant buildout.
Restroom Signs
Restroom signs are among the most scrutinized ADA signs in any commercial facility. They must include the International Symbol of Accessibility (ISA) where applicable, use Grade 2 Braille, have a non-glare finish, and meet specific contrast requirements between the characters and background. Gender-neutral restroom signs have additional symbol requirements introduced in recent accessibility guidance.
Exit Signs
Exit signs must meet both ADA and International Building Code (IBC) requirements simultaneously. In Denver, this means they must be illuminated or internally lit AND meet tactile/Braille requirements if they are permanently mounted at door level. Overhead exit signs (suspended above 80 inches) are exempt from the tactile requirement but must meet illumination and visibility standards.
Directional and Wayfinding Signs
Directional signs that guide building occupants toward accessible features — accessible entrances, accessible restrooms, elevator banks — must incorporate the appropriate accessibility symbols. Pure wayfinding signs that don’t reference accessible features are generally not required to include Braille or tactile characters, but they must still meet minimum character height and contrast requirements.

Key ADA Sign Specifications Denver Businesses Need to Know
Mounting Height and Location
ADA requires that tactile room identification signs be mounted so that the centerline of the sign sits at 60 inches above the finished floor. The sign must be installed on the latch side of the door — the side where the handle is — between 18 and 60 inches from the door frame. If there is no room on the latch side due to a wall or architectural feature, the sign should be placed on the nearest adjacent wall.
Tactile Characters and Braille
All required tactile signs must use raised uppercase characters that are between 5/8 inch and 2 inches high, with a minimum 1/32-inch character relief (how much they project from the surface). Below the tactile characters, Grade 2 Braille is required — this is contracted Braille that uses standard abbreviations, not letter-by-letter spelling. Incorrect Braille is one of the most common compliance errors and something a professional fabricator should catch before installation.
Contrast and Finish Requirements
Characters and their background must have a light-on-dark or dark-on-light contrast. ADA does not specify an exact contrast ratio (unlike WCAG for digital content), but most code interpretations require a clearly perceptible difference. Finishes must be non-glare — glossy or highly reflective sign surfaces do not comply, as they reduce legibility for people with low vision.
Font and Character Spacing
ADA requires the use of sans-serif typefaces with uniform stroke widths. Decorative, script, or highly stylized fonts are not compliant. Character spacing must follow specific width-to-height ratios, and word spacing must allow for legible reading. Many businesses purchase visually attractive custom-designed signs that are not ADA-compliant because of typeface choices — this is a preventable mistake.
ADA Sign Installation in Denver: What to Look for in a Sign Company
Not all sign companies are equally equipped to handle ADA compliance. ADA signage involves specific fabrication requirements — the right substrate, correct Braille specifications, proper character relief — that require both the right equipment and experience with the relevant codes.
When evaluating a sign company for your Denver ADA project, look for the following:
- Experience with commercial ADA projects — Ask specifically about Denver and Colorado work. A company familiar with local building departments knows how inspections are conducted and what reviewers look for.
- In-house fabrication capability — Companies that fabricate their own signs have more control over Braille accuracy, character relief, and finish quality than those who source from third-party suppliers.
- Professional installation — Mounting height and door-side placement are critical. Incorrect installation is one of the most common ADA violations — and it’s entirely avoidable with an experienced installer.
- Full-project coordination — For larger buildouts or renovations, you need a sign partner who can manage a full sign package across multiple rooms, coordinate with your general contractor, and deliver on a schedule that doesn’t hold up your CO.

Frequently Asked Questions: ADA Signs for Denver Businesses
What types of signs must be ADA compliant in Denver?
| Any sign that identifies a permanent room or space — including restrooms, conference rooms, stairwells, offices, and exits — must comply with ADA requirements. Directional signs that guide people to accessible features must also use accessibility symbols. Temporary signs and overhead suspended signage are generally exempt from tactile requirements. |
What are the ADA mounting height requirements for signs in Colorado?
| ADA requires that tactile signs be mounted with the centerline of the sign at 60 inches above the finished floor. Signs must be installed on the latch side of the door (the side the handle is on), between 18 and 60 inches from the door frame. In Colorado, these requirements align directly with federal ADA standards, with no additional state amendments that affect mounting. |
Do all Denver businesses need ADA signs?
| The ADA applies to all places of public accommodation and commercial facilities. This includes retail stores, offices, restaurants, medical facilities, hotels, banks, and government buildings. Businesses with 15 or more employees that are covered employers are also required to provide accessible workplaces. Essentially, if your Denver business is open to customers or clients, ADA signage compliance applies. |
What is the difference between ADA signs and standard signs?
| Standard signs are purely visual — they rely on printed text and graphics. ADA-compliant signs include raised tactile characters and Grade 2 Braille so they can be read by touch. They must also use non-glare finishes, meet minimum character height and contrast requirements, and use specific fonts. Not all signs require these features — only those designating permanent rooms and accessible features. |
Can existing signs be made ADA compliant, or do they need to be replaced?
| In most cases, existing signs need to be replaced rather than modified. ADA requirements are very specific about substrate, character relief, Braille dot specifications, and finish — these cannot typically be added to an existing sign after the fact. When renovating or changing a space, ADA signage updates are typically required as part of the project scope. |
