ADA Tactile Evacuation Signs: Raised Characters, Braille, Mounting Height and Stair Identification

The 2010 ADA Standards for Accessible Design Section 703 (Signs) sets the tactile-sign requirements that apply to every building covered by Title II (state and local government) or Title III (public accommodations and commercial facilities) of the Americans with Disabilities Act. Tactile signs — signs with raised characters and Grade 2 Braille — are required at: signs identifying permanent rooms and spaces (Section 703.1), signs at doors leading to means of egress, signs identifying exit stairs and exit doors. Tactile signs must use raised characters at least 5/8 inch tall and not more than 2 inches tall, with character stroke width 10% to 15% of character height, character spacing 1/8 inch minimum, and a non-glare surface finish. Pictograms accompanying tactile signs must have a 6-inch high field for the pictogram. Braille characters must be Grade 2 (contracted) Braille, dome-shaped, located directly below the corresponding text. The sign must be mounted with the baseline of the tactile characters between 48 and 60 inches above the floor, alongside the latch side of the door (or right side for double-doors). For evacuation planning, the most critical tactile signs are EXIT signs, stair identification signs, and area-of-refuge signs.

ADA Section 216.4 specifically requires tactile signs at: doors at exit passageways, exit discharge, exit stair enclosures (with the word EXIT or EXIT ROUTE); doors leading directly to the exterior (with the word EXIT); doors leading to areas of refuge (with the words AREA OF REFUGE or AREA OF RESCUE ASSISTANCE plus the international symbol of accessibility); doors at the exit discharge (with the word EXIT). The tactile sign supplements but does not replace the overhead illuminated exit sign. Specifically, the IBC Section 1013.4 still requires the illuminated overhead exit sign for visual signaling. Tactile signs are mounted at door height so a person with low or no vision can locate them by touch as they approach the door. Best practice is to also include directional information on tactile signs at intermediate corridor decisions — a tactile sign reading EXIT WITH ARROW at a corridor T-intersection helps a visually impaired occupant navigate to the exit. The posted evacuation plan does not directly depict tactile signs but should mark exit doors clearly enough that a sighted reader can guide a visually impaired companion.

IBC Section 1023.9 (Stairway Identification Signs) requires a tactile sign at every floor landing inside each exit stair enclosure providing the following information: the stair identifier (e.g., STAIR A), the floor level, the upper and lower terminus of the stair (e.g., FLOORS 1 TO 8), the direction to the exit discharge, and the level/direction that provides exit discharge (e.g., GROUND LEVEL — EXIT). The sign typically also indicates whether re-entry from the stair onto the floor is allowed at this level (re-entry permitted, re-entry not permitted, re-entry permitted at floors X, Y, Z). The sign is mounted with the centerline at 60 inches above the floor, on the wall adjacent to the door or in the door swing path so the sign can be located by touch by a person exiting the stair on that floor. NFPA 101 Section 7.2.2.5.4 has similar requirements. The posted evacuation plan should label each stair on each floor with its identifier (Stair A, Stair B) so the plan matches the physical signs and an occupant can navigate to a specific stair if directed by responders.

Areas of refuge — fire-rated areas where mobility-impaired occupants wait for assisted evacuation — must be marked with tactile signs reading AREA OF REFUGE or AREA OF RESCUE ASSISTANCE alongside the International Symbol of Accessibility (ISA — the figure in a wheelchair). The sign is mounted at the door entrance to the area, between 48 and 60 inches above the floor. Inside the area of refuge, additional signage provides instructions for using the two-way communication system (typically: 'Push to talk — emergency communication') and indicates the maximum number of wheelchair-bound persons the area is designed to hold (calculated under IBC Section 1009.6 — at least one wheelchair space per 200 occupants of accessible spaces served by the area of refuge). The directional signage in the corridor leading to the area of refuge points to its location, with the ISA symbol and the AREA OF REFUGE text. The posted evacuation plan should mark areas of refuge with the ISA symbol and a clear text label so all occupants — sighted and visually impaired — understand that the area exists, where it is and how to reach it.

Several states have adopted stricter tactile sign requirements than the federal ADA baseline. California Title 24 (California Building Code Chapter 11B) requires CBC-specific tactile signs in addition to ADA signs, including Spanish-language tactile signs in certain areas and specific California State Architect-defined symbols. Massachusetts requires Massachusetts Architectural Access Board-approved signs in some configurations. Texas Accessibility Standards (TAS) closely follow ADA. New York City under Local Law has additional signage for evacuation chairs and shelter-in-place. Designers in these jurisdictions must consult the local accessibility standard alongside the federal ADA — the local rule usually preempts where stricter. Tactile sign manufacturers typically offer code-compliant signs labeled for each jurisdiction so the facility can purchase pre-certified signs. The posted evacuation plan reflects the building's physical signage and route configuration, regardless of which jurisdiction's tactile sign standard applies; the plan does not need to depict the tactile signs themselves but should match the routes the signs describe.

The posted evacuation plan is a visual document and is not directly accessible to a visually impaired person. However, the plan provides the framework that the tactile signs reference: an occupant who knows the building's layout from prior orientation can use the tactile signs to confirm their location and navigate the egress route. Best practice is to provide an orientation walkthrough for visually impaired occupants — typically arranged through facility HR or a disability support office — so the occupant builds a mental map of the building. A tactile Braille version of the floor plan can be made by specialty vendors for visually impaired occupants who request one, particularly in facilities with significant numbers of visually impaired occupants (specialty schools, rehabilitation centers, government buildings). The visual posted plan still serves visually impaired occupants indirectly by guiding the sighted companions, family members and responders who may assist them during an evacuation. The plan should be physically accessible (mounted at 48-60 inch reading height alongside the tactile signs at exit doors) so sighted occupants can read it while standing next to a visually impaired companion who is reading the tactile sign.

EvacPlan Generator (www.evacplangenerator.com) does not produce tactile signs themselves — those are physical products manufactured by specialty sign vendors — but the planning workflow integrates seamlessly with tactile-sign installations. The plan should label every exit door, every stair (with Stair A, Stair B identifiers matching the physical tactile signs), every area of refuge (with the ISA symbol from the medical/accessibility category of the symbol library), and the path of egress from each area. When tactile signs are installed or updated — for example, a renovation adds a new stair with new tactile signage — the posted plan can be updated in minutes to match the new identifiers and configuration. For multi-language environments, the plan can include both English and the local language as text annotations alongside the icons, providing visual support to occupants who do not speak English fluently. The PDF export prints the plan at the appropriate size for wall-mounted posting alongside tactile signs, with high contrast and large fonts for readability by occupants with low-vision impairment who are not fully blind. The whole tactile-sign ecosystem and the posted plan together create accessible wayfinding for the full spectrum of occupants.
