ADA Signage: What the Law Actually Requires (Federal, State, and Local)

A Certificate of Occupancy inspection is one of the most common ways businesses find out their signage isn't compliant — usually right before an opening date. ADA signage isn't a style choice; it's layered requirements from three levels of government, and getting it wrong can mean a failed inspection or, worse, a federal civil rights complaint. Here's what actually applies, and how we handle it.

What Counts as "ADA Signage"

Not every sign in a building needs to meet the full ADA standard. The law draws a line based on what the sign identifies:

• Permanent rooms and spaces — restrooms, room numbers, exit stairs, office and suite identification — require both tactile (raised) characters with Braille and visual characters.

• Directional and informational signs — "Restrooms →," hours of operation, occupancy rules — only need to meet visual character requirements. No Braille or raised lettering required.

• Exceptions include temporary signs posted 7 days or less, building addresses, occupant name signs, and menus.

Getting this classification right is the first compliance decision, since it determines whether a sign needs Braille and raised text at all.

Federal Baseline: The 2010 ADA Standards

The 2010 ADA Standards for Accessible Design (Section 703) are the federal floor, and they're detailed:

Tactile characters (for permanent rooms/spaces):

• Raised a minimum of 1/32", 5/8" to 2" tall, uppercase, sans-serif only

• Grade 2 Braille required directly below the text

• Non-glare finish with clear light-on-dark or dark-on-light contrast

Braille specifications:

• Dot height 0.025"–0.037", dot diameter 0.059"–0.063"

• Positioned at least 3/8" below the raised text

Mounting:

• Tactile characters: baseline between 48" and 60" above the finish floor

• Visual-only signs: minimum 40" above the floor

• Mounted on the latch side of a single door, on the inactive leaf of double doors, or on the nearest adjacent wall when there's no latch-side space — with 18"x18" of clear floor space in front

Pictograms used for permanent room/space signs need a minimum 6" field height, with raised and Braille text descriptors underneath.

These numbers haven't changed since 2010 — there's no newer federal standard superseding them, so this is still the baseline every project has to hit.

The New York State Layer

New York doesn't just adopt the ADA — the Building Code of New York State incorporates its own accessibility standard (ICC A117.1) as part of the state's Uniform Fire Prevention and Building Code. In practice, that means two sets of requirements apply at once, and wherever they differ, the stricter one wins — more generous clearance or a lower reach range, whichever provides greater access.

It's worth being clear about what a building permit does and doesn't cover: passing your local Certificate of Occupancy inspection means your signage satisfies the state building code. It does not, by itself, guarantee ADA compliance — the ADA is a federal civil rights law that exists independently of any local sign-off. A CO in hand doesn't prevent an ADA complaint if a sign is later found out of spec.

The Local Layer

Enforcement happens locally. Here on Long Island, your building department — whether that's the Town of Oyster Bay, a village building department, or another Nassau County municipality — reviews signage as part of your permit and Certificate of Occupancy process under the state Uniform Code. That's the practical checkpoint most businesses encounter: signage gets inspected alongside everything else in a build-out or renovation before you're cleared to open.

The takeaway for a business owner: satisfying your local building inspector is necessary, but treat it as the state-code checkpoint it is, not a substitute for actual ADA compliance.

How We Handle ADA Signage

We fabricate ADA-compliant signage to the federal spec — correct character proportions, Grade 2 Braille placement, non-glare finishes with proper contrast, and raised text at the required depth — and we account for the New York State layer so the signage clears your local building department the first time.

That includes:

• Restroom, room ID, and suite signage with compliant tactile lettering and Braille

• Directional and informational signage in matching visual styles

• Correct mounting guidance — height, door-side placement, and clear floor space — so installation doesn't undo a compliant sign

• Low minimums — whether you need one restroom sign or a full building package, we size the order to the job, not the other way around
