A property manager once showed us a set of interior signs that had passed every visual check — right colors, right fonts, right size — and still failed inspection. What did they miss?

Looking Compliant Isn’t the Same as Being Compliant

Most people assume ADA signage compliance is mostly about looking accessible: big enough letters, a wheelchair icon where needed, maybe some Braille dots. If it looks the part, it should pass. That assumption is exactly what gets projects sent back to the fabricator. Our complete guide to ADA signage requirements covers this in depth: ADA sign requirements are governed by precise, measurable tolerances — character height, stroke width, finish reflectivity, mounting height (48″–60″ to the baseline of tactile characters), and Grade 2 Braille dot spacing — and a sign can look entirely reasonable to the eye while failing several of them at once.

Contrast, Braille, and the Details That Get Missed

Take contrast, one of the most commonly missed requirements. The code doesn’t just require “different colors” for text and background — it requires a specific contrast ratio, measured, not eyeballed. A trendy charcoal-on-navy pairing can look sharp on a mood board and fail outright on an inspector’s meter. This isn’t unique to one industry, either: we see the same pattern in medical offices, multi-family housing, and retail build-outs — the sign was designed to match the brand palette first, and compliance was checked second, if at all.

Braille placement trips up just as many projects: it has to sit below the corresponding text with dot spacing and height inside precise tolerances, which is not something you can fix by swapping a font. Parking signage carries its own set of pitfalls, too — see our breakdown of the most common ADA parking sign mistakes that draw litigation in California.

Why Fixing It Later Costs So Much More

Here’s what makes this expensive rather than just annoying: by the time most businesses discover a compliance issue, the sign is already fabricated and mounted, and sometimes the wall is already painted around it. Reworking a non-compliant sign after installation costs far more than getting it right the first time — and can delay a certificate of occupancy for a project that’s otherwise ready to open. Permitting adds another layer of timing risk; our guide to sign permit approval timelines walks through what to expect before you’re locked into a schedule.

Bring Your Sign Partner in Earlier

The real fix isn’t a better checklist at the end — it’s moving the sign fabricator’s involvement earlier. Compliance is inexpensive to design in and expensive to retrofit. If you’re sourcing signage for an upcoming project, our list of questions to ask before buying ADA signs is a useful starting point. If you’ve got a renovation or new build-out on the calendar, loop your sign partner in during the design phase, not after the walls are already up — it’s the single cheapest ADA decision you’ll make on the project.
