ADA Sign Mounting PegsDoes the ADA Require Signs?

Yes, the ADA requires signs. The Americans with Disabilities Act (ADA) explains what signs should look like and where they should be hung.

It is important for building managers and owners to properly mount ADA signs to ensure compliance with section 703.4 of the ADA Standards and avoid fines or lawsuits. Additionally, hanging ADA signs throughout your facility at the correct height and in the right way benefits everyone—When signs are consistently positioned, it is easier for anyone to find, read, and navigate with signage. 

Keep reading our ADA Sign Mounting FAQs to ensure that your facility’s signage meets ADA mounting regulations. Keep in mind that California’s sign mounting guidance varies slightly from federal regulations; visit Green Dot Sign’s ADA Sign Requirements Guide for guidance on these and other special signage circumstances.

What is the Required ADA Sign Height?

ADA sign height must be between 48 and 60 inches measured to the baseline of the raised lettering, as specified in section 703.4.1 (Height Above Finish Floor or Ground):

Tactile characters on signs shall be located 48 inches (1220 mm) minimum above the finish floor or ground surface, measured from the baseline of the lowest tactile character and 60 inches (1525 mm) maximum above the finish floor or ground surface, measured from the baseline of the highest tactile character. 

This 12-inch range of allowable hanging height, between 48 inches and 60 inches allows signs of varied size to be consistently hung on the same visual line along a wall. Often, it works well to hang all signs 54” from the floor to the bottom of all room signs. With a tape measure and attention to detail, ADA sign mounting per regulations is easy!

By requiring a narrow range of ADA sign height and locations, anyone anywhere in the United States who needs signs to navigate knows where to look or feel for signs. The height range is also accessible both many building users such as folks in wheelchairs and children and adults walk around.

Note that mounting height guidelines are different for elevator car controls in section 703.4.1.

What Locations Require ADA Signs?

Tactile ADA signs are required by every permanent room or space. Signs are almost always positioned at doorways, as doors mark the point of entry into a permanent building space or other area that requires identification. 

A key portion of section 703.4.2 Location explains the two location components that apply to most ADA signs:

Where a tactile sign is provided at a door, the sign shall be located alongside the door at the latch side. Signs containing tactile characters shall be located so that a clear floor space of 18 inches (455 mm) minimum by 18 inches (455 mm) minimum, centered on the tactile characters, is provided beyond the arc of any door swing between the closed position and 45 degree open position.

The below graphic illustrates standard ADA sign mounting: to the handle side of the door, at 48″ – 60″ height, and centered 9″ away from the door .

Are there ADA Sign Mounting Guidelines and Exceptions?

Yes. Because each building and doorway is unique, the ADA Standards includes guidance for where to mount signs at perplexing locations, such as double doors, and where to hang signs when there is not space. 

Section 703.4.2 (Location) of the ADA Standards describes solutions for three specific situations:

  • Where a tactile sign is provided at double doors with one active leaf, the sign shall be located on the inactive leaf. 
  • Where a tactile sign is provided at double doors with two active leafs, the sign shall be located to the right of the right hand door. 
  • Where there is no wall space at the latch side of a single door or at the right side of double doors, signs shall be located on the nearest adjacent wall.

Can I Hang an ADA Sign on a Door?

In exceptional cases, yes, a sign may be centered on door instead of a wall. Section 703.4.2 explains when an ADA sign may be mounted on the push side of a door. All three of the criteria below must be met in order for door mount ADA sign to be compliant:

  1. The sign is on the push side of door
  2. The door closes automatically
  3. Door does not have a hold-open device

In practice, almost all signs qualifying for this criteria are for restrooms and locker rooms.

Note the ADA sign height stays the same as wall mounted signs.


California has state-specific guidelines for mounting restroom signs on doors and adjacent walls. More details on exceptions can be found in our complete ADA sign requirements page.

ADA sign mounting with tape and siliconeHow Should an ADA Sign be Mounted to a Wall or Door?

Tape and silicone is the most common way to hang ADA signs. These adhesives work quickly and bind to most wall surfaces.  

The Green Dot Sign® preferred approach to mounting ADA signs utilizes four wood pegs. This method not only reduces plastic production and use, but is also the most secure. If specified in your order, our signs are shipped with the pegs glued into holes made on the back of the sign blank. Customers then use Green Dot Sign’s provided pattern to drill four holes into their wall. 

Next, silicone or eco-friendly caulking compound is applied to the holes and sign back to ensure a strong, long-term hold.  

Many of our experienced clients insist upon mounting signs with wooden pegs, fining that adhesives such as foam tape do not withstand vandalism and other risks associated with long-term use.

For those who need to quickly install signs or don’t want to use power tools, the best option is to use silicone in conjunction with adhesive provided by the sign manufacturer. Green Dot Sign® orders with foam tape will receive signage with the tape already secured to the back of their signs. To mount, simply make a circle of silicone on the back of your sign, remove the backing from the tape, and firmly stick your sign to the wall.
