1 Scope
NOTE This standard covers the furnishing and installation of interior architectural signage and building-mounted, code-required signage in commercial, institutional, and light-industrial buildings. (1.1)
NOTE The scope includes tactile room-identification signs, overhead and projected directional and wayfinding signs, regulatory and informational panel signs, dimensional letters and logos, and the electrically illuminated and non-illuminated signs that carry those messages. (1.2)
NOTE This standard establishes the minimum accessibility, material, finish, contrast, fabrication, and installation requirements that apply to all of those signs. (1.3)
1.4Sign types, messages, locations, quantities, and mounting heights for each sign shall be as indicated on the contract drawings and the sign and message schedule.
NOTE Signage is governed simultaneously by accessibility law and by life-safety code, and deficiencies in either are routinely the last items to clear at final inspection; tactile and Braille signs that do not comply with the ADA 2010 Standards and ICC A117.1 expose the Owner to civil-rights liability, and code-required egress signage is mandated by the IBC and NFPA 101 to allow occupants and first responders to find their way out during an emergency. Because signage is procured late and installed near the end of the project, it is frequently value-engineered or rushed, and the result is the single most common category of accessibility citation at occupancy. (1.5)
1.6The Contractor shall develop and obtain approval of a complete sign and message schedule.
1.7The Contractor shall fabricate every accessible sign to the tactile, Braille, contrast, and finish requirements of the governing standard.
1.8The Contractor shall verify mounting height and location for every sign before installation.

4 Quality Assurance
4.1 Governing Accessibility Standard
ICC A117.1 and ADA 2010 — both apply, more stringent governs
ICC A117.1 only (per adopted building code)
ADA 2010 Standards only
Local amended accessibility standard — see drawings
4.1.1Most commercial projects must satisfy both the federal ADA 2010 Standards for Accessible Design and the accessibility provisions of the locally adopted building code, which incorporates ICC A117.1.
4.1.2The two standards are largely harmonized for signage but differ in some particulars; where they differ, the more stringent requirement shall govern unless the Authority Having Jurisdiction directs otherwise.
4.1.3The Architect shall identify the governing standard and the signs subject to accessibility requirements.
4.2 Which Signs Are Subject to Accessibility Requirements
NOTE Not every sign in a building is subject to the tactile and Braille requirements, but the rules for which signs are governed are precise and are frequently misapplied. (4.2.1)
Tactile + visual (permanent room/space identification) — raised characters and Braille required
Visual only (directional/informational) — legible characters, contrast, non-glare finish
Code-required egress sign — comply with IBC/NFPA + tactile where required at the door
Decorative/dimensional — no character-legibility requirement
4.2.2Signs that identify a permanent room or space — restrooms, stairs, exits, room numbers, and similar permanent designations — shall provide tactile (raised) characters and Braille.
4.2.3Signs that provide direction to or information about a space, and signs that are purely directional, shall comply with the visual-character requirements for height, contrast, and finish but do not require tactile characters and Braille.
4.2.4Where a single sign serves both functions, the portion designating the permanent space shall be tactile.
4.2.5The Contractor shall classify every sign on the schedule by these rules and shall not omit tactile characters and Braille from any sign that designates a permanent room or space.
4.3 Mounting Location and Height Verification
NOTE Tactile-sign location relative to the door — and the resulting clear approach to the sign — is among the most frequently cited signage deficiencies, and it cannot be corrected by adjusting the sign; it requires moving the sign. (4.3.1)
4.3.2The Contractor shall verify, before installation, the mounting height and the mounting location of every tactile sign against the governing accessibility standard, the door schedule, and the door swing.
4.3.3The Contractor shall not rely on a single standard rough-in dimension but shall confirm each tactile sign against the latch-side and approach-clearance requirements below.
5 Sign Types and Accessibility Requirements
NOTE The sign and message schedule and the floor plans determine which signs occur, what they say, and where they are located. (5.1)
NOTE The requirements below establish the accessibility, character, contrast, finish, and mounting properties that apply to each governed sign. (5.2)
5.4 Tactile (Raised) Character Height
0.6252
0.6250.7511.52
Default: 0.625 in
NOTE The 5/8 in. minimum applies to tactile room-identification copy; larger tactile characters within the range are used where the message or design calls for greater prominence. (5.4.1)
5.4.2Raised characters shall be 5/8 in. minimum and 2 in. maximum in height, measured as the height of the uppercase letter "I" of the font, per ADA 2010 Section 703.2.5 and ICC A117.1.
5.4.3Tactile characters shall be accompanied by visual characters that, where they are the same characters, may share the raised characters provided the raised characters also satisfy the visual-character requirements.
0.031250.0625
0.031250.0468750.0625
Default: 0.03125 in
5.5.1Raised characters shall be raised 1/32 in. minimum above their background, per ADA 2010 Section 703.2 and ICC A117.1.
5.5.2Raised characters shall be uppercase, sans-serif, and shall not be italic, oblique, script, highly decorative, or of other unusual form.
5.5.3Character stroke, character spacing, and the proportion of character width to height shall comply with the character-form provisions of Section 703.2.
5.5.4Raised borders or decorative elements shall be separated from the raised characters by the minimum clearances of the standard so that they cannot be mistaken for characters by touch.
5.6 Braille
○ Contracted (Grade 2) Braille, domed/rounded dots, positioned below the corresponding text
○ As required by AHJ where a different contraction standard is adopted
NOTE An incorrect or mistranslated Braille string is not detectable by sighted reviewers and is a common, costly defect. (5.6.1)
5.6.2Tactile signs shall provide contracted (Grade 2) Braille with domed or rounded dots conforming to the dimensions and spacing of ADA 2010 Section 703.3 and ICC A117.1.
5.6.3Braille shall be positioned below the corresponding raised text; where the text is multi-line, the Braille shall be placed below the entire text.
5.6.4Braille shall be separated 3/8 in. minimum from any other tactile characters and from raised borders and decorative elements.
5.6.5Braille shall read left to right.
5.6.6The Contractor shall verify the Braille translation of the approved message before fabrication.
5.7 Pictograms
5.7.1Where a pictogram is required or used to identify a permanent space, the pictogram shall have a field height of 6 in. minimum, per ADA 2010 Section 703.6 and ICC A117.1.
5.7.2The pictogram field shall not contain raised characters or Braille.
5.7.3The verbal equivalent of the pictogram shall be provided directly below the pictogram field as tactile characters and Braille.
5.7.4The pictogram and its field shall have a non-glare finish and shall contrast with each other, either a light pictogram on a dark field or a dark pictogram on a light field.
5.8 Visual Character Legibility
Sans-serif, conventional spacing, uppercase and lowercase permitted (directional/informational)
Sans-serif, uppercase only (where matching tactile copy)
NOTE The minimum visual-character height is determined by the height of the sign above the floor and the horizontal viewing distance per the table in Section 703.5.5; overhead signs and signs viewed from a distance require taller characters. (5.8.1)
5.8.2Visual characters on directional, informational, and overhead signs shall comply with the visual-character provisions of ADA 2010 Section 703.5 and ICC A117.1.
5.8.3Characters shall be conventional in form — sans-serif or simple serif — and shall not be italic, oblique, script, highly decorative, or of other unusual form.
5.8.4Character stroke thickness shall be 10 percent minimum and 30 percent maximum of the height of the character, and character spacing shall be 10 percent minimum and 35 percent maximum of character height.
5.8.5The Contractor shall confirm the minimum visual-character height per Section 703.5.5 against the schedule and the mounting condition.
5.9 Contrast
○ High contrast — light characters on dark background or dark characters on light background
○ 70% minimum luminance contrast (where AHJ specifies a numeric threshold)
NOTE Insufficient contrast is a frequent and avoidable deficiency; hue difference without luminance difference does not satisfy the requirement. (5.9.1)
5.9.2Characters and their background shall contrast, either light characters on a dark background or dark characters on a light background, per ADA 2010 Sections 703.2 and 703.5 and ICC A117.1.
5.9.3Where the Authority Having Jurisdiction or the contract documents specify a numeric threshold, a luminance contrast of 70 percent minimum between characters and background shall be provided.
5.9.4The Contractor shall select character and background colors that achieve high contrast and shall not rely on color hue alone.
5.10 Finish
○ Non-glare (matte/eggshell) finish on characters and background
○ Gloss finish — only where permitted for non-tactile decorative signs
NOTE A glossy finish produces specular reflection that defeats legibility for users with low vision. (5.10.1)
5.10.2Characters, their background, pictograms, and pictogram fields on signs subject to accessibility requirements shall have a non-glare finish, per ADA 2010 Sections 703.2, 703.5, and 703.6.
5.10.3A glossy finish shall not be used on the characters or background of governed signs.
5.10.4Decorative dimensional letters and signs not subject to the legibility requirements may use a gloss finish where shown on the schedule.
5.11 Mounting Height of Tactile Signs
4860
485460
Default: 48 in AFF
5.11.1On a sign with multiple lines of tactile copy, both limits must be satisfied simultaneously: the lowest line shall not fall below 48 in. and the highest line shall not exceed 60 in.
5.11.2Tactile characters shall be mounted with the baseline of the lowest tactile character 48 in. minimum above the finished floor, and the baseline of the highest tactile character 60 in. maximum above the finished floor, per ADA 2010 Section 703.4.1 and ICC A117.1.
5.11.3The Contractor shall lay out tactile signs to the baseline of the tactile copy, not to the top or center of the sign panel, because the requirement is measured to the character baseline.
5.12 Mounting Location of Tactile Signs
○ Latch side of the door, clear of the door swing, with the required clear approach
○ Nearest adjacent wall where there is no wall on the latch side (e.g., double doors)
NOTE This is the single most common reason a correctly fabricated tactile sign fails inspection. (5.12.1)
5.12.2A tactile sign identifying a room or space entered through a door shall be located on the latch side of the door, per ADA 2010 Section 703.4.2 and ICC A117.1.
5.12.3Where there is no wall space on the latch side — at double doors with no center mullion, or where the latch side is obstructed — the sign shall be placed on the nearest adjacent wall.
5.12.4A person shall be able to approach within 3 in. of the sign without encountering protruding objects or standing within the swing of a door.
5.12.5The Contractor shall confirm, for every tactile sign, that the latch-side wall location provides the required clear approach and is outside the door swing.
6 Materials and Construction
6.1The substrate, copy method, and finish of each sign shall be appropriate to the sign type, the environment, and the durability required, and shall produce the raised characters, Braille, contrast, and non-glare finish required for governed signs.
NOTE The selections below establish the construction of the panel signs and dimensional copy; the accessibility properties above govern in all cases. (6.2)
6.3 Panel Sign Substrate
Acrylic (cast/extruded, ASTM D4802) — interior panel signs, layered subsurface graphics
Photopolymer — integrally raised characters, Braille, and pictograms in one piece
Phenolic (high-pressure laminate) — high-abuse, wet, and exterior-adjacent interior areas
Aluminum / metal (ASTM B209) — durable panel and overhead signs, exterior building ID
NOTE Photopolymer is the predominant substrate for tactile room-identification signs because the raised characters, Braille, and pictograms are formed integrally in a single, durable, vandal-resistant piece that reliably meets the 1/32 in. relief and the Braille-dome requirements. (6.3.1)
NOTE Acrylic conforming to ASTM D4802 is widely used for layered subsurface-graphic panel signs; phenolic high-pressure laminate is specified for high-abuse, wet, and aggressive-cleaning environments; and aluminum and other metals conforming to ASTM B209 are used for durable interior panel and overhead signs and building-mounted identification. (6.3.2)
6.3.3Interior plastic signs shall meet the applicable flame-spread and combustibility requirements of the building code for the location in which they are installed.
6.4 Copy and Character Method
Integrally molded raised characters and Braille (photopolymer)
Raised characters applied/laminated to panel; Braille raster beads or formed
Subsurface (second-surface) printed graphics with applied raised tactile copy
Engraved/routed two-color laminate (non-tactile signs)
NOTE Integrally molded photopolymer produces characters and Braille in one piece and is the most reliable method for tactile signs. (6.4.1)
6.4.2The copy method shall produce raised characters of the required 1/32 in. minimum relief and Braille of the required dome dimensions.
6.4.3Where raised characters are applied or laminated to a panel, the bond shall be permanent and the characters shall not be subject to peeling or removal.
6.4.4Braille produced by inserting raster beads into drilled holes shall use beads that seat permanently and present a rounded dome.
6.4.5Engraved or routed two-color laminate shall not be used for tactile room-identification signs.
6.5 Dimensional Letters and Logos
Fabricated metal (aluminum) dimensional letters
Cast metal dimensional letters
Cut acrylic / plastic dimensional letters
Not used on this project
6.5.1Dimensional letters and logos used for building, lobby, and donor identification shall be fabricated or cast of the specified material with the specified face finish and returns, and shall be mounted by concealed studs, a mounting pattern, or a backer as shown on the shop drawings.
6.5.2Dimensional copy that also serves as permanent room or space identification subject to accessibility requirements shall additionally satisfy the raised-character, Braille, contrast, and finish requirements.
6.5.3Where the dimensional treatment cannot meet those requirements, a separate compliant tactile sign shall be provided at the door.
7 Illuminated Signs
7.1Where signs are electrically illuminated — internally illuminated panel and cabinet signs, illuminated dimensional letters, and illuminated exit signs — the sign shall be a listed assembly and shall be connected, where it serves an egress function, to the required power source.
Not applicable — no illuminated signs in this scope
Internally illuminated panel/cabinet sign (UL 48)
Illuminated dimensional letters / channel letters (UL 48)
Illuminated exit sign / directional exit indicator (UL 924)
○ Normal power with integral battery backup (90-minute minimum)
○ Emergency/standby power branch circuit
○ Self-luminous / photoluminescent (where permitted by the AHJ)
7.2Electrically illuminated signs other than emergency egress signs shall be listed to UL 48 (Electric Signs).
7.3Illuminated exit signs and illuminated directional exit indicators shall be listed to UL 924 (Emergency Lighting and Power Equipment).
7.4Illuminated exit signs shall remain illuminated for not less than 90 minutes upon loss of normal power, supplied either by an integral rechargeable battery or by an emergency/standby power source, as required by the IBC and NFPA 101.
7.5Light sources shall be LED unless otherwise indicated.
7.6Electrical connection, circuiting, and coordination with the building emergency power system shall be coordinated with the electrical work, and the sign supplier shall confirm the supply voltage and the means of connection on the shop drawings.
7.7Self-luminous and photoluminescent exit signs may be used only where specifically permitted by the Authority Having Jurisdiction and where the listing and illumination performance satisfy the adopted code.
8 Code-Required Signage
NOTE Code-required signs are mandated by the building and fire codes and by NFPA 101, and their messages, sizes, and locations are fixed by code rather than by design preference. (8.1)
8.2The Contractor shall provide every code-required sign shown on the life-safety/egress plan and required by the adopted codes, even where a sign is omitted from the architectural sign schedule.
8.3The Contractor shall reconcile the architectural sign schedule with the life-safety plan during submittal.
8.4 Exit Signs
8.4.1A sign reading EXIT, complying with the visibility, size, and illumination requirements of the IBC and NFPA 101, shall be provided at each exit and exit-access door where required by the code.
8.4.2Directional EXIT signs shall be provided where the path of egress travel is not immediately apparent.
8.4.3Where required at the door to an area of refuge, an exterior area for assisted rescue, an exit stairway or ramp, an exit passageway, or the exit discharge, a sign stating EXIT in visual characters, raised (tactile) characters, and Braille complying with ICC A117.1 shall be provided adjacent to the door.
8.5 Stairway Identification and Floor-Level Signs
○ Provide — 18 in. x 12 in. minimum, top at 5 ft above the floor landing, at each landing
○ Not applicable — stairway does not connect more than three stories
○ Provide tactile floor-level sign (visual + raised characters + Braille, ICC A117.1) at each landing door
○ Not applicable
8.5.1A stairway identification sign shall be provided at each floor landing in an interior exit stairway and ramp connecting more than three stories, per IBC/IFC Section 1023.9.
8.5.2The stairway identification sign shall identify the stairway, designate the floor level, indicate the terminus (top and bottom) of the stairway, state the story of and direction to the exit discharge, and indicate the availability of roof access for the fire department.
8.5.3The stairway identification sign shall be a minimum of 18 in. by 12 in., and the top of the sign shall be located 5 ft above the floor landing in a position readily visible when the door is in both the open and closed positions.
8.5.4A floor-level identification sign in visual characters, raised characters, and Braille complying with ICC A117.1 shall be located at each floor-level landing, adjacent to the door leading from the interior exit stairway and ramp into the corridor, to identify the floor level, per IBC Section 1023.9.
8.6 Area-of-Refuge Signage
○ Provide — 'AREA OF REFUGE' with International Symbol of Accessibility at each refuge door
○ Not applicable — no areas of refuge in this building
8.6.1Doors providing access to an area of refuge shall be identified by a sign that includes the term AREA OF REFUGE and the International Symbol of Accessibility, per the IBC.
8.6.2Where the area of refuge contains instructions for its use, two-way communication, or directions to the area of refuge, signage providing those instructions and directions shall be provided as required by the IBC and NFPA 101.

8.7.1Additional regulatory and informational signs required by the adopted codes — maximum-occupant-load signs in assembly spaces, NO EXIT signs on doors that could be mistaken for an exit, fire-door and door-blocking signs, restroom identification, and stairwell re-entry signs where applicable — shall be provided as required by the life-safety plan and the codes.
9 Installation
9.1 Layout and Verification
○ Required — verify a representative tactile sign installation for height, location, and approach before proceeding
○ Not required — Contractor verifies each sign against the schedule
9.1.1Before installing any sign, the Contractor shall lay out the locations and mounting heights of all signs and shall verify the layout against the approved sign and message schedule, the door schedule and door swings, the life-safety plan, and the governing accessibility standard.
9.1.2Particular attention shall be given to the latch-side location and clear approach of tactile signs and to the baseline mounting height of tactile characters.
9.1.3The Architect or the Owner's accessibility reviewer may require verification of a representative set of tactile signs before the balance are installed.
9.2 Mounting Method
Concealed adhesive (foam tape + silicone) — typical interior tactile and panel signs
Mechanical fasteners with concealed or vandal-resistant heads
Concealed mounting studs into blocking/backing — dimensional letters, heavy panels
Bracket / flag mounting for projected (perpendicular) overhead signs
Suspended (ceiling-hung) mounting for overhead directional signs
NOTE Typical interior tactile and small panel signs are mounted with a combination of double-sided foam tape and a compatible silicone adhesive that holds the sign permanently while accommodating minor wall irregularities; mechanical fasteners with concealed or vandal-resistant heads are used where vandalism is a concern. (9.2.1)
9.2.2Signs shall be mounted level, plumb, and securely by the method appropriate to the sign type and the substrate to which they attach.
9.2.3Heavy panel signs, dimensional letters, and projected or suspended overhead signs shall be anchored to solid blocking, backing, or structure.
9.2.4The Contractor shall coordinate in-wall blocking with Gypsum Board Assemblies and shall not rely on fasteners into gypsum board alone for any sign that bears weight or could be pulled or vandalized. 9.2.5Projected (flag-mounted) and suspended overhead signs shall be installed at a height that provides the vertical clearance required for circulation and shall comply with the protruding-object and overhead-clearance limits of the accessibility standard.
9.3 Adhesive and Surface Preparation
9.3.1Surfaces receiving adhesive-mounted signs shall be clean, dry, sound, and fully cured before the sign is applied.
9.3.2Signs shall not be adhered over loose, dusty, freshly painted, or contaminated surfaces.
9.3.3The Contractor shall use the sign manufacturer's recommended adhesive system and shall observe the manufacturer's cure time before the sign is subjected to handling or cleaning.
9.4 Cleaning and Protection
9.4.1Signs shall be protected from damage, dust, and overspray until substantial completion, and protective films shall remain on faces until final cleaning.
9.4.2At completion, signs shall be cleaned per the manufacturer's instructions with non-abrasive cleaners only.
9.4.3Abrasive cleaners shall not be used, as they dull the non-glare finish, reduce contrast, and can damage raised characters and Braille.
