ADA Signage Requirements for Illinois Businesses: A Plain-English Guide

ADA signage isn’t just a box to check — it’s a legal requirement, and getting it wrong can mean fines or a failed inspection. Here’s what business owners in the Rockford area need to know.

What the ADA requires

The Americans with Disabilities Act sets standards for signs that identify permanent rooms and spaces — restrooms, exits, stairwells, room numbers, and similar. These signs must include:

• Tactile (raised) characters and Grade 2 braille for permanent room identification.

• High contrast between the characters and their background, with a non-glare finish.

• Correct mounting height and location — generally on the latch side of the door, 48–60 inches from the floor to the baseline of the text.

• Sans-serif fonts and specific character proportions for legibility.

Where it applies

Most public-facing and commercial buildings are covered: offices, restaurants, retail, schools, medical facilities, and places of worship. Directional and overhead signs have their own rules for size and viewing distance.

Common mistakes we see

• Decorative fonts on permanent-room signs (not allowed).

• Braille spaced or positioned incorrectly.

• Glossy finishes that create glare.

• Signs mounted on the door itself instead of the adjacent wall.
